Well done on getting this project out.  I like ruby (though I'm
new), and I like wxWidgets, so I'm keen on getting this running.

I have ubuntu Linux running.  I checked out the code with:
root at opal:/home/rhys/wxride# svn checkout
svn://rubyforge.org/var/svn/wxride/trunk

Then I cd into the trunk directory.
Then try to run the program but get this error:

root at opal:/home/stone/wxride# cd trunk/
root at opal:/home/stone/wxride/trunk# ruby wxRIDE.rb
./lib/ui/AboutDialog.rb:13: uninitialized constant
WxRide::AboutDialog::RUBY_PATCHLEVEL (NameError)
        from /usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
        from /usr/lib/ruby/1.8/rubygems/custom_require.rb:27:in
`require'
        from wxRIDE.rb:94
root at opal:/home/stone/wxride/trunk#


Is any kind and wise soul able to tell me how to resolve this?

Many thanks,
StonePiano

Hey Stone,

Thanks for the kind interest and support for wxRIDE.  wxRIDE now has a User
and Development list, and I'd prefer to keep chatter about wxRIDE limited to
it's own list.  Just so you know, you can subcribe to them.  As for your
problem, the error is coming from the fact that your Ruby doesn't set
RUBY_PATCHLEVEL for some reason, when it should be.  If you don't mind me
asking, what version of Ruby are you running?  You can find out by typing in
ruby --version on a command line, and it'll tell ya.  If you could though,
please reply to this email on wxride-users at rubyforge.org.

Thanks,

Subject: [wxruby-users] Some problems with Wx::Grid
Message-ID: <68adf8c45d1a7f50fbf1a74d6fb1e4f2@ruby-forum.com>

Recently I have been writing an app making some use of the Grid control,
and I have experienced some problems with it. After playing around with
the grid for a while I sometimes succeed to make the cells appear
outside of the window, as if the actual grid would be placed in the top
left corner of the screen, while it actually is in rather small window
in the center of th screen. I attach a screenshot for better clarity.
The occurance of the error is always accompanied  by changing of the
cell "marker"/cursor from beeing thick black rectangle to beeing thin
grey rectangle, and can be provoked by inputing random data in the grid
and scrolling fast to the right by pressing down the left arrow key, and
repeting that couple of times. Im using Ruby 1.8.6 and WxRuby 1.9.5. I
know it may be hard to tell but if anyone sees any errors in my code I'd
be gratefull for pointing them out. Here is how the grid is made:


class ImageGrid < Grid
    def initialize(parent, image)
        @rows = 100;
        @cols = 100
        @img = image

        super(parent, -1)
        self.create_grid(@rows, at cols)
        set_default_cell_alignment(ALIGN_CENTRE, ALIGN_CENTRE)


        # this event will actually come when text is entered in 1 cell
        evt_grid_range_select() do |e|
            # deselection gives whole table...
            top_row = e.get_top_row
            left_col = e.get_left_col
            bottom_row = e.get_bottom_row
            right_col = e.get_right_col
            # after cursor has left the cell... could be because of edit
            cur_row = get_grid_cursor_row
            cur_col = get_grid_cursor_col


            # input, not range selection
            if top_row == 0 and left_col == 0 and bottom_row == @rows-1
and right_col == @cols-1
                # ...
            # range selection, not input
            else
                # ...
            end

        end # ...grid range select event
    end # ...initialize
end # ...class ImageGrid

Hi,

Does anyone know how to detach controls from a panel or frame? What I
want to do is click a button and redraw a new UI without the button. Is
there any possible was to do this? Thank you for any help in advance. :D

If your layout is controlled by sizers, use Sizer#remove or 
Sizer#detach, then call destroy on the removed Window. You may need to 
call Sizer#layout afterwards to adjust to the new window contents.

If not, just call Window#destroy. It's one of the rare occasions that 
calling this directly is useful.

Another way, if your planning to re-use the control, is to call
hide()/show(false) on the button, then call layout() on the window, to
re-draw the controls.  Hide will make it invisible, so that it's no longer
there.

An example:

begin
    require 'rubygems'
rescue LoadError
end
require 'wx'

class MyFrame < Wx::Frame
    include Wx
    def initialize(*args)
        super
        @button1 = Button.new(self,1000,"Hide Me!")
        @button2 = Button.new(self,1001,"Show other button")
        hbox = BoxSizer.new(HORIZONTAL)
        hbox.add(@button1,1,ALL)
        hbox.add(@button2,1,ALL)
        set_sizer(hbox)
        evt_button(1000) do
            @button1.show(false)
            layout()
        end
        evt_button(1001) do
            @button1.show(true)
            layout()
        end
    end
end

Wx::App.run do
    MyFrame.new(nil,:title=>"Button Hiding Example",:size=>[200,60]).show()
end

L8ers,

Hi Daniel

Thanks for the report. Unfortunately I couldn't test out your code 
because it requires other files that you haven't included. We ask that 
when posting a problem or bug, you simplify your code to demonstrate the 
problem rather than just copying your enitre program.

http://wxruby.rubyforge.org/wiki/wiki.pl?MailingLists

I have a couple of suggestions on organisation and style that may help. 
I think you could simplify your code quite a bit and that should help 
iron out the bug.

My main one would be to use Wx::Timer rather than ruby Threads+sleep to 
count down the time until the alarms go off. The way Ruby threads are 
designed makes them ill-suited for many uses with GUI libraries, so 
don't use them unless you really have to - and here, you don't.

>   
Here you could make your code a lot simpler by using client_data. This 
allows you to associate any normal ruby object (eg an Alarm object) with 
an item in a ComboBox. So when the user clicks the edit button, you just 
find the Alarm object associated with the currently selected value in 
the ComboBox, and start editing it. You would then be able to handle an 
arbitrary number of Alarms.

>     @checkTue = CheckBox.new(@aPanel, -1, "Tuesday")
A CheckListBox might be better here: 
http://wxruby.rubyforge.org/doc/checklistbox.html

> $minDef = \"#{$comboMinVal}\"
There are much easier and safer ways to save an object with settings to 
file. Look up "Marshal" or "YAML" for ruby - these will allow you to 
save and load Alarms with no extra work.

> class Alarm
>   def initialize
>   
I would design your Alarm class to have attributes for the hour, minute 
and second, an array for the days of the week, and a boolean to 
represent whether it's on or off.

attr_accessor :hour, :minute, :second, :days, :active

Have a look at http://www.rubycentral.com/pickaxe/tut_classes.html

In the constructor for your TextCtrl, maybe something like:

evt_set_focus { self.background_colour = Wx::RED }
evt_kill_focus { self.background_colour = Wx::WHITE }

I'm not sure that on all platforms, the native TextCtrl is allowed to 
change the background colour. But this works fine for me on OS X.

I've just committed a patch (SVN:1664) to fix these 
ObjectPreviouslyDeleted errors sending events to destroyed Wx::Windows.

It seems to fix the samples; if possible, please test SVN HEAD to see 
whether the problem is resolved for you.

Message-ID: <000f01c89ff3$6362d570$a50ba8c0@valcom.com>

I'm having trouble changing the color of Buttons in WxRuby.  I'm calling
set_background_colour (and set_foreground_colour) and the calls return true,
but the button remains gray.  

 

In searching the documentation it seems that the problem might be related to
should_inherit_colours, which can prohibit color changes, but the
documentation is confusing.  (Doesn't specify whether should_inherit_colours
should return true or false.)

 

Any suggestions?

 

Eric

Generally a major part of wxRuby's approach is that standard native 
controls like Wx::Button take the standard theme colours, depending on 
the user's desktop settings. You don't mention what platform you're 
using, but I'd expect that some desktops just won't permit non-standard 
colours to be used here.

If you could say more about what your application's trying to do here, 
perhaps we could suggest a better way of desiging a UI that will achieve 
it whilst still looking harmonious. There are several other options eg 
Wx::BitmapButton.

Subject: [wxruby-users] alpha release of Weft QDA 2
Message-ID: <48085361.6080802@pressure.to>

Hi

I just put out an alpha release of Weft QDA 2, an application written in 
wxRuby. Weft QDA is used by sociologists, anthropologists and similar 
for the analysis of textual data like interviews, fieldnotes and 
published literature.

You can read more about the release: 
http://rubyforge.org/pipermail/weft-qda-users/2008-April/000130.html

Anyway, the specific purpose of the application won't be relevant to 
most people here, but there might be a few things of interest in there 
about coding a large-ish database-backed application in wxRuby.

It uses a large number of wxRuby GUI classes, with a mixture of XRC and 
wxSugar coding to build the interface. DialogBlocks and xrcise were used 
to speed up development of the main windows.

It uses a hand-written object-relational mapper with an Observer 
mechanism to update the GUI with changes in the database. All the core 
classes can be used without a GUI, and this makes the GUI event-handling 
code pretty simple.

It's packaged up so it feels like a completely native app on Windows and 
OS X from installation to use. I gave up on rubyscript2exe; it's fairly 
convenient for a quick solution for smaller apps, but limited. So on OS 
X I used Platypus to create the binary, and distribute it as a .dmg 
file. On Windows it sets up a fully-functional ruby distribution via the 
NullSoft Installer System (NSIS). This give smaller downloads, and make 
it feel like a compiled app (with some tweaking, in the rakefiles).

Anyway, if anyone's interested in knowing more on these topics, I can 
perhaps post a wxRuby tutorial at some point.

cheers

Subject: [wxruby-users] wxRuby / wxWigets with C++
Message-ID: <op.t9tfikh3xdblfq@jarod>

Hi,

I am experimenting with integration of C++ and Ruby. What exactly I would  
like to do is to provide an option to use Ruby and wxRuby for creation of  
GUI and doing algorithms in C++ and then displaying results in the openGL  
Canvas.

I can easily use openGl / Glut in "render" function in C++ say class  
VisualiseGraph, build using SWIG an extention to Ruby and then use this  
function (that does not take any parameters and returns void) to display  
on the wxGLCanvas
(
  @canvas.evt_paint { @canvas.paint { render } }
).

But I would also like to transfer the data from the form built using Ruby  
into some classes in C++. Like parameters: numbers and string. But I am  
wondering if it is possible to create controls in Ruby and then just  
assign then into C++ fields (the controls not values). For example

class FormInCpp
{
	wxTextField * someText;

	void setSomeText(wxTextField * param){
		someText = param;
	}

}

then use SWIG to build extention in module say Llap

and then

txt = Wx::TextCtrl.new(self, -1, "val")

form = Llap::FormInCpp.new
form.setSomeText(txt)

I thought these are in fact the same controls, they were written in C++,  
but I guess txt is not of type [wxTextField *], but rather
  #<SWIG::TYPE_p_wxTextCtrl:0xb7c49944>
  so how to get the pointer to wxTextField so I can manipulate the control  
 from cpp class like this

someText->GetValue()

and then do smthing with this value.

hi. I want to make button that can change picture when mouse is entering
and can click to use function. and this is my code.


    @button2 = BitmapButton.new(@window, -1, @picturebox1_bmp,
Point.new(248,89),       Size.new(53, 53))
    @button2.evt_mouse_events{ |event| evtmouse2(event) }
    evt_button(@button2.get_id()) { |event| evtbtn2()}


    def evtmouse2(event)
      if event.entering == true
        @button2.set_bitmap_label(@picturebox2_bmp)
      end
      if event.leaving == true
        @button2.set_bitmap_label(@picturebox1_bmp)
      end
    end


    def evtbtn2()
      #mycode
    end

[ Sebastien asked - when I use "BusyCursor.busy do .. end" within a 
begin/rescue clause, and an exception is raised, the BusyCursor 
continues - how can I can I stop it? ]

J'ai rencontr? le m?me probl?me. Je l'ai r?solu avec 'ensure', comme 
ci-dessus:

[I ran into the same problem. I resolved it with ensure, like this:]

begin
  Wx::BusyCursor do
    #long code
  end
rescue
ensure
  a_frame.cursor = Wx::Cursor.new(Wx::CURSOR_ARROW)
end

Selon moi, nous devrons le d?panner dans wxRuby
http://rubyforge.org/tracker/index.php?func=detail&aid=19646&group_id=35&atid=218

[In my opinion, this is something we should fix in wxRuby - bug added]

I wasn't totally clear what you wanted - do you want to end up with a 
ruby script that calls some C++ extensions, or a compiled C programme 
that calls wxRuby to do a GUI. I think the latter will be harder...

Not quite sure how this would work. Unless the interface of your C++ 
library is very complex, it might be easier to do it the other way 
around, ie create a simple ruby wrapper around your C++ library (using 
SWIG or RICE) then use Ruby to transfer the values into the C library. 
Is there a particular reason this won't work for you?

SWIG provides a lot of useful functions for doing this, if you want. See 
http://www.swig.org/Doc1.3/Ruby.html#Ruby_nn50

in particular, SWIG_ConvertPtr which converts a VALUE to the underlying 
C++ object.

It's generally used little directly, as it's easier to use %extend to 
write methods in which the placeholder variable $self refers to the C++ 
object.

Another, easier way to implement this type of functionality, is to use the
following given methods:

BitmapButton#set_bitmap_focus()<http://wxruby.rubyforge.org/doc/bitmapbutton.html#BitmapButton_setbitmapfocus>
BitmapButton#set_bitmap_hover()<http://wxruby.rubyforge.org/doc/bitmapbutton.html#BitmapButton_setbitmaphover>
BitmapButton#set_bitmap_selected()<http://wxruby.rubyforge.org/doc/bitmapbutton.html#BitmapButton_setbitmapselected>
BitmapButton#set_bitmap_disable()<http://wxruby.rubyforge.org/doc/bitmapbutton.html#BitmapButton_setbitmapdisable>

Though, the way you have now, gives you an idea of how to do things, this
sort of thing is already implemented, just so ya know. ;-)

Should be:

BitmapButton#set_bitmap_disabled()<http://wxruby.rubyforge.org/doc/bitmapbutton.html#BitmapButton_setbitmapdisabled>

My mistake.

This won't run. I get 'in `render': wrong number of arguments (2 for 1) 
(ArgumentError)' when I copy your example verbatim.

Removing the extra argument in render and rerunning gives me:

C:/ruby/lib/ruby/gems/1.8/gems/scruffy-0.2.2/lib/scruffy/graph.rb:131:in 
`render': undefined method '[]' for #<Wx::PaintDC:0x591d318> 
(NoMethodError)

I would like to render a graph directly to the screen - is this possibly 
using scruffy / wxruby?

Andreas

I think you've misunderstood the purpose of the example. It was just to 
show a set up where a scruffy graph would render using a wxRuby DC 
(device context) rather than to an SVG object.

What remains for someone with motivation to do is to convert or 
translate the calls that scruffy makes to an svg object inside the 
library (eg svg.line, svg.circle) into the equivalent DC calls 
(dc.draw_line, dc.draw_circle). The relevant parts of scruffy to look at 
are in the components and layers directory.

Probably it would be easiest to create a bridge class that translates 
svg calls as dc calls. Then you could use the the Scruffy library 
unmodified.

I did enough to persuade myself that this was likely a viable approach, 
but have no particular interest in pursuing at the moment.

No, not directly without you or someone else doing some work.

The other approach would be to wrap a C++ wxWidgets component that 
renders SVG (such as wxArt2D) in Ruby. This is probably harder.

Or, the simplest route would just to be to install a ruby extension that 
renders SVG to PNG or some other raster format that wxRuby can read, and 
then display that.

I think ImageMagick can rasterize SVG in this way.

You're right I did misunderstand. I might pursue your first suggestion 
to create the svg and the load it as an image, though it is suboptimal.

I understand you can divert the output procedure to the screen but since 
it is not a part of the "standard package" - and I thus need to write it 
myself - I don't think it is a good route to take, considering time and 
reliability.

Thanks!

Hi,
All programs I make with wxruby crash when they are closed. This happens
with the examples as well.

Is this fixed in the svn?
I tried building the svn from source, but once I compiled and installed
it, I got some question about a missing symbol when running my program.

Thanks,

Please say which platform you're on, and what version you're using. And 
could you show us some simple, complete code that demonstrates the 
error, or at least indicate which sample(s) you're talking about?

There is a fix in SVN for a longstanding irritating bug which could 
crashes on closing frames under some circumstances, if event handlers 
were attached. But without knowing more about your bug, it's hard to 
know whether this is the problem - but it sounds quite possible. With 
SVN head I now have no crashes on exit on any sample.

Again, can you give us a clue about what symbol was missing? And what 
wxWidgets you are building against?

Subject: [wxruby-users] Transparent line in Frame
Message-ID: <7c83d0dbe249ef046e1d8572c1b2af3f@ruby-forum.com>

Hi

Thanks for a great GUI toolkit!

I want to draw transparent lines in a Frame. I have the following setup
but my lines are not transparent.

My colour object is created using:
   transparent_blue = Colour.new(0,0,255,100)

and I draw lines using a pen with this colour:
   @pen = Pen.new(transparent_blue)

In evt_paint of frame I have:
   dc.set_pen(@pen)
   dc.draw_line(x1,y1,x2,y2)

The line is blue but there is no transparency.

I set the alpha level to 100 where 255 is supposed to be completely
opaque.

I'm on Windows XP SP2 and

C:\>ruby --version
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

Please help!

Regards, Andreas

The standard DC doesn't support transparency (except on OS X I think). 
But you can instead use wxGraphicsContext which fully supports 
transparency, antialiasing and other advanced drawing tools like splines 
and transforms. You create one from an ordinary DC like this:

paint.do | dc |
  gdc = Wx::GraphicsContext.create(dc)
  gdc.stroke_line(0, 0, 500, 500)
  # etc
end

Unfortunately the wxWidgets developers decided to make the API to 
GraphicsContext different to DC, but the results are worth it for 
graphical apps.

Thanks! I'm having a bit of trouble, though. Here is a small example I 
use:

require 'wx'
include Wx

App.run do
  frame = Frame.new(nil, :title => 'GraphicsContext example', :width => 
[300,400])

  frame.evt_paint do
    frame.paint do |dc|
      gdc = GraphicsContext.create(dc)
      siz = dc.size
      h, w = siz.height, siz.width
      #dc.draw_line(0,0,w,h)
      gdc.stroke_line(0,0,w,h)
    end
  end

  frame.show
end

It should draw / stroke a diagonal line in the frame. This works if I 
use draw_line.

What am I missing? :)

It seems with GraphicsContext, you need to set some sort of pen before 
starting drawing - there is no default pen when it's first created.

I just wanted to report back to the list on one chart-making technique
that has been working out well for me so far.  I am using a popular open
source scientific and mathematical plotting package called Gnuplot.  

http://www.gnuplot.info/  

To use Gnuplot I started with a Ruby wrapper called rgplot (found on
RubyForge).  

http://rubyforge.org/projects/rgplot

After playing with rgplot a while, I came to the conclusion that the
interface wasn't really suited for my needs, so I studied the code,
learned a few key things, and ultimately came away with the one or two
lines of code that setup the pipe between Ruby and Gnuplot.  Then I
wrote my own proof-of-concept wrapper to plot a couple of charts:
clustered bar charts, stacked bar charts, line graphs, etc.  

Unfortunately, my wrapper is not really good enough for public
consumption, but I can explain how it works and you might be able to use
the same idea for your own applications.  Basically, Gnuplot is run as a
subprocess from Ruby.  You pass whatever commands and data you want to
Gnuplot through a stream to that subprocess.  When it's done plotting,
Gnuplot writes an image file to disk (JPG or other format).  Finally you
create a Wx::Image from the image file and draw it as Wx::Bitmap on a
dc.  

You can get pretty nice looking charts out of Gnuplot but you might have
to work at it.  The Gnuplot syntax can be a pain, but it does come with
a lot of example files that help a lot.  It also has an interactive GUI
that is handy for testing command syntax.  One thing that Gnuplot cannot
do is pie charts.  However, if you really need pie charts, they would be
easy enough to implement yourself by drawing directly with wx.  

To implement your own wrapper for Gnuplot, I definitely recommend
studying rgplot (or use it "as is", if it works for you).  One thing to
look out for is that Gnuplot will be running asynchronously from
whatever else you are doing in Ruby or wx.  So I use the on_timer event
to watch for the image file to be completed.  After a lot of
experimentation, I found that (File.exists?(path) and File.size(path) >
0) is the best test to see if the image file is actually ready to be
loaded into wx.  Also, if you need to create multiple charts at the same
time, you will need to write a manager that sequentially feeds jobs to
Gnuplot and then collects the resulting images.  I was able to do that
without too much trouble, again using the on_timer event.  

Maybe someday I'll be able to put together a wrapper that I would be
willing to share.  At the moment I'm not working on this actively, but I
hope to get back to it in a few months.

Best of luck,
P

I'm running GNOME version 2.22.1 on Ubuntu 8.04 release candidate (it is
possible this is the problem, I'll use a livecd later to check on an
earlier ubuntu). I'm using the gem retrieved using 'gem install wxruby',
which is 1.9.5.

As for some code none of the samples I tried worked. Here is nothing.rb
(minus comments):
begin
  require 'rubygems' 
rescue LoadError
end
require 'wx'
Wx::App.run do 
  frame = Wx::Frame.new(nil, :title => "Minimal wxRuby App")
  frame.show
end

Gives this:
minimal/nothing.rb:13: [BUG] Segmentation fault
ruby 1.8.6 (2007-09-24) [i486-linux]

I'm using 2.8.7.1, BUT I also have version 2.6.3.2 runtime installed for VLC.
I don't have the i18n package or the wx-common package installed.
As the the missing symbol, I don't know right now but I'll get back to you.
If it is of any significance, during installation it said the PrinterDC component would be skipped for some reason.

I use current 7.10 Ubuntu, so no need to test there to see if it's the

OK, there's something wrong if nothing.rb isn't working. Most of the 
bugs that have been fixed in SVN since 1.9.5 are pretty esoteric.

One thing springs to mind here. The ruby-core team decided it was a good 
idea to change bits of ruby's GC code between two patch levels of ruby 
1.8.6 and this created a problem in wxRuby which is now fixed in SVN. 
This would show up as something like "object allocation during GC" error 
message.

Could you try running it under gdb please? The binary is stripped so it 
may give anything useful, but worth a shot.

 gdb --args ruby -rubygems minimal/nothing.rb

Then at the gdb prompt:

Then when it crashes:

And post back the first 20-odd lines of what results.

The binary gem includes a statically linked version of wxWidgets so your 
system version shouldn't matter. It will matter if you're building 
yourself against a distro package.

That's normal on GTK. If that's the only component being skipped, it's 
trying to build everything else including all optional components like 
Scintillla, MediaCtrl, OpenGL. wxRuby's configure should detect if these 
aren't available and skip them, but it could be that this hasn't 
happened and that's the reason for the missing symbol. If we knew the 
symbol that would pin it down

Does that mean we can assume it the fact I'm running 8.04 that's causing the problem?
Upgrading to the rc has caused me nothing but trouble, I'll be patient in the future:)

It could be, or it could just be that that version of Ubuntu has 
upgraded to ruby 1.8.6-p114 and that's causing problems. Rather than 
trying to compile wxRuby yourself, you could also see if ruby-1.8.6-p110 
works if you compile it yourself.

http://rubyforge.org/frs/?group_id=426

I will likely move onto 8.04 when it's ready and offered by Ubuntu's 
update manager, so future gems will target that.

Unfortunately there's not much useful left in there, because the binary 
in the gem is stripped to reduce size.

Hi,

How do I make a bitmap toggle button? I tried making a toggle button
and then drawing onto it, but that didn't work. Also, I tried a bitmap
button but that wouldn't remain pressed like a toggle button.

Thanks for any help,

warrior

There's nothing in standard wxRuby and wxWidgets like that, apart from a 
"toggle" tool in a Wx::ToolBar.

If you search for "wxBitmapButton bitmap" you'll turn up references to 
several wxWidgets C++ classes that do this. Maybe you could adapt the 
code from one of those to Ruby.

Also, you might adapt from wxPython's GenBitmapToggleButton. The python 
code should be easier to translate into wxRuby.

Thanks Alex,

wxPython's GenBitmapToggleButton seems to rely heavily on the toggle
mixin, and it might require more digging in than I had originally
intended. I'll try it later and keep posted.

Subject: [wxruby-users] Black background using paint_buffered
Message-ID: <7152d40c27957a000ada2e4b4de334e2@ruby-forum.com>

Hi,

To avoid flickering during screen updates in a Frame on Windows I
recently switched from

paint do | dc |
   #...
end

to

paint_buffered do | dc |
   #...
end

The background colour of the Frame is set to WHITE, which is respected
under paint, but is replaced by BLACK under paint_buffered.

The painting jobs seems fine, though all my black lines become invisible
:P

Is there something I can do to sort this out? Perhaps supply my own
buffer...

Thank you!

Regards, Andreas

Yes, you can pass your own buffer as an optional argument to 
paint_buffered. It should be a Wx::Bitmap of the appropriate height and 
width.

I will see if the ruby code that does paint_buffered could make the 
bitmap background match the window's.

Dang you Alex,

You beat me to it. :P  Actually, another suggestion, would be to use
Wx::DC#draw_rectangle(), in which you set the Pen and Brush with the color
you want to use.

Simple Example (Not Tested):

<code>
pen = Wx::Pen.new(Wx::WHITE)
brush = Wx::Brush.new()
brush.colour(Wx::WHITE)

dc.set_pen(pen)
dc.set_brush(brush)
dc.draw_rectangle(0,0,self.width,self.height)

.... do your drawing here ....
</code>

L8ers,

Hi
I've been trying to find out how to use wxglade with ruby in google, but I
haven't been able to find anything on the topic so far, so I was wondering
what do you guys use instead? I mean you don't really hand code all the gui
stuff do you, you must have some visual gui designer available?

I'm new to Gui so please be kind!
Thanks

Use wxGlade but save the resulting files as "XRC". This is an XML format 
you can load into ruby.

http://wxruby.rubyforge.org/wiki/wiki.pl?Using_GUI_Designers
http://wxruby.rubyforge.org/wiki/wiki.pl?UsingXRCise

And see the example 'samples/xrc/xrc_sample.rb'

Hi,
I'm having some trouble allowing the user to edit a multi-column
listctrl. I can do the first column fine, simply by calling
ListCtrl::edit_label in the activate event, but it seems impossible to
do this for the other columns for two reasons. 1, the activate event
doesn't allow you to get the column, and 2, edit_label onl;y works for
the first column.

I can't find a reference right now, but I have a feeling that only the 
first column is editable - I think because not all the native controls 
support editing of secondary columns.

You might look into Wx::Grid, which does support this. Its appearance is 
highly customisable so you could make it look more like a ListCtrl if 
you wished.

Hi

Just a quick follow-up on the recent thread about displaying images eg 
graphs generated by other libraries such as gnuplot, scruffy, rmagick etc.

The upcoming 1.9.6 release of wxRuby will support loading images from 
arbitrary IO-like objects such as Files, Sockets and StringIO. Hopefully 
this will be easier and more direct than messing around with writing to

Yes. Only descendants of Wx::TopLevelWindow - either Frames or Dialogs - 
can have no parent. Any other Wx::Window has to have a valid parent.

If you want to show no Frame at all, just use Frame#hide.

If you want a minimal frame, you could use Wx::MiniFrame or perhaps a 
shaped frame - there is an example of the latter in bigdemo.rb.

Subject: [wxruby-users] wxRuby 1.9.6
Message-ID: <4819167A.2010808@pressure.to>

I'm happy to announce that the latest version of wxRuby is available now 
from Rubyforge. This release contains many bugfixes, enhancements and a 
few additional features, and it's a recommended upgrade.

== INSTALLATION ==

The release can be downloaded from:
http://rubyforge.org/frs/?group_id=35&release_id=21668

Or installed via rubygems for Windows, Linux and OS X:
(sudo) gem install wxruby

Note that the upcoming ruby version 1.8.7 is NOT supported (see below)

== WHAT'S NEW ==

This release contained a record number of changes among recent releases; 
these are detailed in full in the ChangeLog, but highlights include:

* New MingW build for Windows (somewhat experimental - see below)
* Added AboutDialogInfo and AnimationCtrl GUI classes
* Added ToolBar and Animation helper classes
* Substantial improvements to Image class such as raw data manipulation 
and reading to IO
* Minor syntax enhancements and additional methods in existing classes
* Many fixes to long-standing and newly identified bugs, crashers, and 
memory leaks
* Additions to the samples and documentation

== PLATFORMS AND RUBY VERSIONS ==
A quick note on where wxRuby is going with regards to ruby versions.

Firstly, the One-Click Installer on Windows is likely to move over to 
compiling with MingW (gcc on Windows) instead of the Microsoft 
toolchain. This is very good news for wxRuby - we're currently relying 
on old, unsupported and unavailable versions of MSVC. wxRuby under MingW 
is also significantly faster, and will make it easier for contributors 
on Windows to work on the core library. However at present a few classes 
are not available - eg GLCanvas

For more information, see:
http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/4056d40003e05728/5d4ebedd430dec4a

Note that the -mingw build will NOT work with the current OCI - you must 
use the gem tagged -mswin32

With regard to ruby versions, 1.8.6 is currently the preferred version, 
although recent 1.8.x releases should work. The emerging 1.9.x releases 
will be fully supported, although there is a bug in ruby 1.9.0 which 
currently breaks important functionality in wxRuby.

The upcoming ruby 1.8.7 version introduces numerous internal and API 
changes that are not backwards compatible, and cause a real headache for 
library maintainers. There are no plans to support this version at present.

== BUGS ETC ==
The bugfixes for this release mean that the bug list on Rubyforge is 
down to a small list most of which can only be fixed by changes to 
wxWidgets. So please do report any crashes or wrong behaviour with this 
release to get the final stable release as good as possible.

== THANKS ==
Thank you very much to everyone who contributed patches, bug reports and 
code samples to this release. Particular thanks to Mario, who has been 
the driving force in getting the MingW build flying.

cheers
