lyle,

i have a problem installing fxruby 1.6 gem on linux. the fox16.so
compiled fine. everything seems to be in its place but require "fox16"
doesn't seem to work.

henon at golem:~$ irb

here are the last lines of the gem installation process. it says that
there is nothing to do for make install. is this ok?

I'm experiencing a closely analogous error on a Debian Etch system.  It doesn't matter whether the file is installed via gem or via compiling the tarball.  The symbol Fox is still undefined.
test.rb:3: uninitialized constant Fox (NameError)

Where does one find the documentation for fox14?  That gem appears to be working flawlessly, (Well, there's a strange error in the unicode example, but perhaps that wasn't expected to work until fox16.), but the only api documentation I've found has been for fox16.

I just did a fresh install on Fedora Core 4 and everything works as 
expected. Could you send me a copy of the file:

	/usr/local/lib/ruby/gems/1.8/gems/fxruby-1.6.0/ext/fox16/gem_make.out

It may be in a slightly different location, depending on where you've 
installed Ruby. I'm not sure what I'm looking for, but I can at least 
see if there are any obvious differences between my copy of 
gem_make.out and yours.

Thanks,

Lyle

Message-ID: <43d756720606041358q1d287c37hfd69e1ea84ae5226@mail.gmail.com>

dear (FX)Ruby hackers,

lyle has released FXRuby 1.6.0 some days ago. so it was a good
opportunity for me to fix some more bugs and release annother version
of foxGUIb which is tested against FXRuby 1.6.0.
the most interesting feature Fox1.6 brings to you is unicode support.
(see foxGUIb/test/unicode_test_japanese.rbin)

thanks for all the feedback and the bug reports.

enjoy ;)

==========================
foxGUIb v0.7 Release Notes
==========================

== What is foxGUIb? ==
   foxGUIb is a GUI creator and code generator for FXRuby. It's a
   convenient tool that makes it easy to quickly build complex and
   good looking graphical user interfaces for Ruby.

== Whom is foxGUIb for? ==
   * FXRuby newbies who want to experiment with the widgets and layouts.
   * FXRuby experts who want to prototype parts of their GUI components rapidly.
   ... ok, lets say everyone who wants to create a GUI with FXRuby ;)

== What has changed? ==
   * Fixed the bug that allowed to change properties of a
     deleted widget (caused a crash)
   * Fixed several bugs that led to crashes when typing
     improper values into the property manipulators. e.g.:
     backColor="bad input" instead of "200,255,255"
   * on startup foxGUIb logs important version infos to the
     log file. the log file is appended instead of replaced.
     in case of a problem you can send me your logfile.
   * some minor convenience fixes.

Charles, I don't think this difference is significant; it just 
indicates that your Ruby is installed under /usr instead of /usr/local.

I've compared both yours and Henon's gem_make.out files to mine (which 
was for a build under FC4) and the only obvious differences are:

+ For the Debian builds, the "platform" part is "i486-linux" instead of 
"i686-linux"
+ For the Debian builds, "-lruby1.8" is included in the final link step 
(the one that builds fox16.so). It's not included in mine.

Neither of these differences are ringing any bells for me, and so I 
don't know what to tell you to do. I suspect that there's something 
"interesting" about how the version of Ruby that's bundled with Debian 
is built, but I don't have access to that operating system.

Are any other Debian users reading this? Any clues?

Lyle

Well, if you just did "configure; make; make install", then FOX got 
installed in /usr/local/lib and not /usr/lib.

If that's the case, the solution to your problem can be found on this 
page from the FXRuby User's Guide:

Hope this helps,

I didn't follow all of that very well, but I think your question boils
down to, "How do I change the text of a label?" If that's the
question, you change it using the text accessor method, e.g.

    @header.text = "Contents of file " + new_filename

Note that you don't have to create a new label every time, and in fact
that's sort-of a wasteful thing to do. Better to just change the text
of the existing label widget (as shown here).

P.S. Please consider subscribing to the fxruby-users mailing list and
posting questions there instead.

if you have downloaded version 0.7 please upgrade to 0.7.1.
while fixing a minor bug i have been inserting a major one that could
result in data loss.
it's really time to build a testsuite for foxGUIb ... i know, but i
don't really have the time. hope this one is stable.

Let me be sure I understand this (I also did a "make intall").
The files are in:
/usr/local/lib/libFOX-1.6.a
/usr/local/lib/libFOX-1.6.la
/usr/local/lib/libFOX-1.6.so
/usr/local/lib/libFOX-1.6.so.0
/usr/local/lib/libFOX-1.6.so.0.0.4
Isn't this one of the "few standard places"?

I'm sorry, I don't understand the question. A "standard place" for what?

Subject: [fxruby-users] Q about combining behaviour of foursplit.rb and
	shutter.rb
Message-ID: <20060605201405.273160@gmx.net>

I have a window that is split into four, like in
foursplit.rb, where there are four buttons.
Using a menu command, one can expand any of
these, so that only this button takes the whole
space.
Now, I want to add a shutter button bar, as there
is one in shutter.rb to the left of the main window.

The user should have the possibility to "expand"
any of the four windows, both from the menu
(as in foursplit.rb), and from one set of Shutterbuttons.

So far, I've tried to change the {}-block of the ShutterButtons
to achieve that:

    shutterItem = ShutterItem.new(@shutter, "Files, data, and pictures", nil, LAYOUT_FILL_Y)
    ShutterButton.new(shutterItem.content, "Expand dirlist", fatBot).connect(SEL_COMMAND) { FX4Splitter::ID_EXPAND_TOPLEFT}
    ShutterButton.new(shutterItem.content, "Expand cell file editor", angryGuy).connect(SEL_COMMAND) { FX4Splitter::ID_EXPAND_BOTTOMLEFT}
    ShutterButton.new(shutterItem.content, "Expand tuning curve plot", sawBlade).connect(SEL_COMMAND) {  FX4Splitter::ID_EXPAND_TOPRIGHT}
    ShutterButton.new(shutterItem.content, "Expand reconstruction plot", redMacOS).connect(SEL_COMMAND) {FX4Splitter::ID_EXPAND_BOTTOMRIGHT}
    ShutterButton.new(shutterItem.content, "Show all four", redMacOS).connect(SEL_COMMAND) { FX4Splitter::ID_EXPAND_ALL }
 
But nothing happens.
What should I do ?

Thank you very much,

Best regards,

Axel

Well, your message-handler blocks don't *do* anything (other than evaluate
the value of a constant like FX4Splitter::ID_EXPAND_TOPLEFT).

I think you want to modify them to call a function on the splitter, for example:

    ShutterButton.new(shutterItem.content,
      "Expand dirlist",
      fatBot).connect(SEL_COMMAND) {
        four_splitter.expanded = FX4Splitter::ExpandTopLeft
    }

Hope this helps,

Dear Lyle,

thanks for that. I have yet another *stupid* question.
In the beginning of my script, I call 

include Fox,

so the code you gave me now produces 

c:/axelhome/ngui/f16.rb:157:in `initialize': uninitialized constant Fox::FX4Splitter::ExpandTopLeft (NameError)

How can I get rid of Fox:: in there ? - I still need it in
another place , though.

Thank you very much!

Best regards,

Axel

You must be using FXRuby 1.4; the code I showed was for FXRuby 1.6. Try this
instead:

    foursplitter.handle(self,
      FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_TOPLEFT), nil)

Hope this helps,

Yeah, that's talking about looking for the include files (e.g. in 
/usr/include/fox-1.6, /usr/local/include/fox-1.6, etc.) so that it can 
build the FXRuby extension.

Right, the FXRuby installation process doesn't attempt to automatically 
"fix" your ld.so.conf file settings that control how shared libraries 
are loaded.

Have you filed a bug report about this yet? I'm not remembering this 
one and I don't (think) I see it in the list at:

	http://rubyforge.org/tracker/?atid=1223&group_id=300&func=browse

If you're pretty sure it's some kind of FXRuby bug, please do go ahead 
and file a bug report for it.

I'm trying to develop a GUI that combines features of
the foursplit.rb and shutter.rb examples.
So there is a bar of ShutterButtons to the left,
and a set of four FX4Splitter elements to the right
of the screen. 
Thanks to expert help from Lyle, it's now possible to
'expand' any of these elements to full size of the
right pane.
Now, I need to add the possibility to switch between
different layers of the right pane, just like in the
shutter.rb application, where you press one of the
ShutterButtons on the left to have that behaviour.

In my code, I set a variable @shutter.current =0, etc..,
like this

...
big_splitter = FXSplitter.new(self, (LAYOUT_SIDE_TOP|LAYOUT_FILL_X|
      LAYOUT_FILL_Y|SPLITTER_TRACKING))
...    
@shutter = FXShutter.new(big_splitter, nil, 0,
      FRAME_SUNKEN|LAYOUT_FILL_X|LAYOUT_FILL_Y,
      0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
...
@switcher = FXSwitcher.new(big_splitter,
      FRAME_SUNKEN|LAYOUT_FILL_X|LAYOUT_FILL_Y, 0, 0, 0, 0, 0, 0, 0, 0)
splitter = FX4Splitter.new(@switcher,
      LAYOUT_SIDE_TOP|LAYOUT_FILL_X|LAYOUT_FILL_Y|FOURSPLITTER_TRACKING)
shutterItem = ShutterItem.new(@shutter, "Files, data, and pictures", nil, LAYOUT_FILL_Y)
    ShutterButton.new(shutterItem.content, "Expand dirlist", big_folder).connect(SEL_COMMAND){
     @switcher.current=0
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_TOPLEFT), nil)}
    ShutterButton.new(shutterItem.content, "Expand cell file editor", pens).connect(SEL_COMMAND){
     @switcher.current=0
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_BOTTOMLEFT), nil)}
    ShutterButton.new(shutterItem.content, "Expand tuning curve plot", messypaint).connect(SEL_COMMAND){
     @switcher.current=1
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_TOPRIGHT), nil)}
    ShutterButton.new(shutterItem.content, "Expand reconstruction plot", drawing).connect(SEL_COMMAND){
     @switcher.current=2
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_BOTTOMRIGHT), nil)}
    ShutterButton.new(shutterItem.content, "Show all four", monitor).connect(SEL_COMMAND){
     @switcher.current=3
     splitter.handle(self,FXSEL(SEL_COMMAND, FX4Splitter::ID_EXPAND_ALL), nil)}
    
Then, I get the error below.
What is the problem here ?

Thank you very much in advance,

Axel

it's normal to get some errors when writing a program. but a
programmer must know how to deal with them. i give you some help so
that you can help yourself in future:

have a look at the error msg: it tells you exactly where in your
source code the error happened. then add some lines that output the
values to see what's going on.

in your case you set the current item of the switcher to an index that
does not exist. so just output the index with puts to see what is the
error in your program.

try that first. if you have more questions i will answer them.
hope that helps,

OK.

> What is the problem here ?

Looking at your code example, I don't see where you're actually adding any
content to the switcher. It's empty, so when you tell it to switch to a
different page (by setting @switcher.current to a new value) you're getting
an error.

Subject: [fxruby-users] Create fails strangely => Fixed resource limits in
	FXRuby/Fox?
Message-ID: <4486A8F5.2020009@iptest.com>

Hi,

I've got a problem with my big and sprawling app.  The behaviour
appears to be related to how many widgets i have in use. (I'm creating
100's and using show/hide at appropriate times.)

What happens when i create a new window is code like this:

    Control.new( owner , ... )
    puts 1
    control.create
    puts 2

will work fine, but at some point will display 1, but not 2, and
the loop it was in will terminate there and then, but the app.
will keep on running, destined to crash oddly later on.

If I put all the creates after all the Control.new calls I get
exactly the same behaviour.  It is completely repeatable.

The create call doesn't raise any exception.

Can someone shed some light on what's going on, or tell me
how I can find out more?

I'm using Fox 1.4.2, Ruby 1.8.2.

Thanks you,
Martin.

To address the subject line first: we don't have any fixed resource 
limits in FOX. The problem that you're describing, however, is almost 
certainly a GC-related bug in FXRuby. A possible workaround is to add 
the line:

	GC.disable

somewhere near the beginning of your program's execution. That won't 
work around all GC-related bugs, but it often does the trick. And I 
stress that it is just a work-around; we need to identify the actual 
underlying bug.

Repeatable bugs are good things. ;)

Can you send me a copy of the program and some instructions on how to 
reproduce the crash? Even better, if you hit on a way to reproduce the 
problem in a pared-down version of the application, that will reduce 
the number of distractions during debugging.

Dear Meinrad,
Dear Lyle,

thank you for your responses.
Meinrad: my problem was not so much to identify
an error line number, but to get some grasp
of what constant actually does what in FXRuby.
This generates a lot of silly questions to more
experienced people, of course. Sorry for that.

So I find that in any learning process, 
redundancy is a good thing. It may be very
nice to have one example for each particular
behaviour FXRuby offers, but if you're learning it,
this may not be enough to disambiguate the
silly things one thinks a program does from
those that actually happen.
I am just starting FXRuby now, but I use
Ruby for command-line things for a longer
period of time. It is the first language
I feel I can talk about serious things to a computer -
otherwise, in university maths studies, you may well
 acquire computer knowledge like other people learn
Old Greek or Sanskrit: not much practical
use in today's Greece or India ...
So I'd suggest to you FXRuby experts to write a
book like Hal Fulton's The Ruby Way - plenty of
code for disambiguation ... . There really may
be a need for it, as amazon doesn't show me any
book entirely about FOX or FXRuby. (I know of
Ruby Developer's guide, but here FXRuby is one
of many topics.)

Then again, I've got another question I couldn't find
an answer to :
In one field of an FX4Splitter, I want to display a PNG
image.
I know how to do this (basically) from the imageviewer.rb
file.
But the image I display needs to be generated first
(by Gnuplot ... no problem to output PNG from there,
except one: to set the size : I don't know what
to tell Gnuplot there:
- how do I see what the size of that

 @imageview_rec = FXImageView.new(@topFrame_rec, nil, nil, 0,
      LAYOUT_FILL_X|LAYOUT_FILL_Y)

is ?
I tried   
    p @imageview_rec.getHeight
    p @imageview_rec.getWidth

but that gives me 1 and 1.

Thank you and sorry for my annoying questions,

Best regards,

Axel

The FXImageView widget isn't going to have a known size until it's created,
and I'm guessing you're calling getHeight() and getWidth() before that happens.

i'm sorry because i did not understand your question right and
therefore gave a answer that was not helpful. Anyway, I am not an
expert in FXRuby. lyle is the real expert. i am just trying my best to
give my experience to people who are new to FXRuby.

i also often had the problem that a widget did not give back it's real
size but 1x1 instead. maybe making a layoutcontainer (verticalframe or
packer) around the imageview might help. then you can get the
containers width and height.

Dear all,

in a GUI, I have a help window with some text and a
Menu toolbar button quite similar to that of textedit.rb:
a help window of class FXDialog appears, displays a
help text, and if you don't need it anymore, there is
a button to close it. This works :)
But when the user wants to see the help window again,
and re-presses the menubar help button, the whole
program exits saying:


c:/axelhome/ngui/f30.rb:686:in `show': This FXDialogBox * already released (RuntimeError)
	from c:/axelhome/ngui/f30.rb:686:in `onCmdShowHelp'
	from c:/axelhome/ngui/f30.rb:893:in `runme'
	from c:/axelhome/ngui/f30.rb:902

This is the function I used :

class MainWindow

 def initialize
    ...
    # Help window

    # init HelpWindow as in helpwindow.rb required by textedit.rb
    @helpwindow = HelpWindow.new(self)
 end
 # Show help window
  def onCmdShowHelp(sender, sel, ptr)
    @helpwindow.show(PLACEMENT_CURSOR)  # line that generated the error.
    return 1
  end
end

How can I make help re-accessible ? In textedit.rb this works,
but I don't know why.

Thank you,

Best regards,

Axel

axel,

there are two ways to do it:
1) not destroying the window just hiding it.
2) calling create everytime you want to show it again.

Hi,
I use the FXTreeList from FXRuby 1.4.
Now I want go get an Item from the list and have only some 
indexinformation example first column and 4th row.
I tried to use getItemAt(x,y) but without success.
Can any one help my?

An other question:
I am a newbie in coding FXRuby.  And the API is not as well as it could 
be. Is there an other source (book ...) where I can get a good 
description how to use FXRuby.

Thanks

You can go through the tree using  "each"

example:
  nodearray=[]
  atreeID.each do |t| nodearray<<t end
  nodearray.each do |a0|
        a0.each do |a1|
            next if a1.numChildren() ==0
            nodearray<<a1
       end
  end

another way:
I think you can give an Identifier (user data) to the item with setItemData
and retrieve it using findItemByData

Hope this help

I would like to set up a container of properties, just as
there is one in the "properties" section of the splitter
window in foxGUIb.
I managed to do this using a function much like the
make_container and add_prop_manipulator methods of foxGUIb.rb,
respectively its required files.

Now, I need to be able to set some of those properties
as checked or unchecked and to attach some methods to them.
For instance, I have a two property fields
for two- and three-dimensional data sets.
Now, if the two-dimensional property is checked,
I'd like to uncheck a property for z-axis name automatically.

How could this be done ?

Thank you very much,

Best regards,

Hi list,
I am writing a small program where I want to display some objects in an
IconList. For a better looking a choose an an .png and created a
FXPNGIcon instance of it.
When the program starts it creates an empty FXIconList and the Icons
will initialized too.
While using the program it should be possible to add some objects to the
list.
But if I run the program is crashes with this message:

"FXDCWindow::drawIcon: illegal icon specified."

I do not now what I had made wrong.
Because if I insert some objects to the iconlist during the
initialization (in de initialize method) it works great!


The code looks like:
def initialize()
....
@iconNonterm = loadIcon("tb_buttonbx01.png")
...
@nonterminallist =
FXIconList.new(nonterminalgroupbox,nil,0,LAYOUT_FILL_X|LAYOUT_FILL_Y|ICONLIST_MINI_ICONS|ICONLIST_EXTENDEDSELECT|ICONLIST_SINGLESELECT|ICONLIST_ROWS|ICONLIST_DETAILED)
@nonterminallist.connect(SEL_RIGHTBUTTONPRESS,method(:onRightNonterm))
...
end
def onRightNonterm(sender,sel,ptr)
    if !ptr.moved
    menu = FXMenuPane.new(sender)
    FXMenuCommand.new(menu,"Neu",nil,sender).connect(SEL_COMMAND,
method(:onAddNonterm))
    newI = FXIconItem.new("Bla", at iconNonterm, at iconNonterm)
    @nonterminallist.appendItem(newI)

end

Thanks a lot

Thats a good explanation, thanks for the pointer. I would not have
thought of the subclassing problem.

How about automatic creation? Methods that need "created" widgets could
check if their parameters are already created, and if they are not, call
create on them.

Fox C++ library might not be the right place to do this. After all,
you'd expect C++ interfaces to have (and enforce) very strict rules. I
believe it would fit more into the FXRuby layer, and would probably be
very easy to achieve with a nice metaprogramming hack.

What do you think?

I have a Combobox, which should have a white background

color of the frame it sits in.
I have tried to correct this by setting

p = $settingsFrame
p.recursive{|w|
			# w.baseColor=STD_BACK_COLOR
			next if w.kind_of? TextField
			next if w.backColor==HEADER_COLOR
                        if /ComboBox/.match(w.type.to_s)
                    	 w.baseColor=WHITE_BACK_COLOR
                         w.backColor=WHITE_BACK_COLOR
                        
                        else
                          w.backColor=STD_BACK_COLOR
                        end
          	}


for WHITE_BACK_COLOR=FXRGB(255,255,255),
and STD_BACK_COLR=FXRGB(128,128,128)

but this changes the background color from gray to white only if I click on
the combobox to show a dropdown of them. Then , everything becomes
white, but after that, it turns to gray again.

Thank you for your help,

Axel
