[wxruby-users] Two issues using GridBagSizer

[Alex Fenton]

Sorry, hit send too early...

The example class you might look at is:
http://weft-qda.rubyforge.org/svn/trunk/weft-qda/lib/weft/wxgui/controls/multitype_control.rb


Note that when swapping items in and out of a Sizer, you should probably 
call layout() afterwards to readjust the relative spacing.

* As for the expansion, you probably want to check that all the inner 
widgets are also set to expand within their parent. So in the case of 
your short textcontrols in the upper pane, they may need to be told to 
expand to full width.

Note that if a Window is the sole child of a managed Frame it will 
resize automatically to fill that Frame. You don't need to put it within 
a sizer.
