Hi, all -
Is it possible to resize the main window on the fly? I want to default to an
800x600 window but give the user an option to resize to 1024.
This approach didn''t work:
class MyWindow < FXMainWindow
def initialize( app )
#...
@mainWindowWidth = 800
# Build the overall Application GUI
# ---------------------------------
super( app,
" MyWindow ",
:width => @mainWindowWidth, :height => 600, :vSpacing => 0 )
#...
winWidth = FXListBox.new( blk1, :opts => LISTBOX_NORMAL )
winWidth.appendItem("800")
winWidth.appendItem("1024")
winWidth.connect( SEL_COMMAND ) do | sender, sel, data |
@mainWindowWidth = data.to_i
app.forceRefresh
end
end
end
#...
if __FILE__ == $0
FXApp.new do | app |
FXToolTip.new( app )
gui = MyWindow.new( app )
app.create
app.run
end
end
My fallback is to save to a file and load the value on the next start, but
is that necessary?
Another question, is this discussion list archived and visible anywhere?
Lyle, your time is better spent coding than answering the same questions
more than once. :)))

It has nothing to do with the application''s main window''s width.

One further refinement necessary, for the record. FXListBox returns a zero-based index into the list, not the text. FXComboBox (according to Lyle) can be inspected with sender.text, but FXListBox is a bit more primitive. My working solution, retaining the variable so I can intelligently size and position things: availWinWidths = Array["800", "1024"] winWidth = FXListBox.new( blk1, :opts => LISTBOX_NORMAL ) availWinWidths.each { | w | winWidth.appendItem( w ) } winWidth.connect( SEL_COMMAND ) do | sender, sel, data | wSel = availWinWidths[ data.to_i ] @mainWindowWidth = wSel.to_i resize(@mainWindowWidth, 600 ) end It works marvelously well. Thank you for the big nudge in the right direction! -- :D -------------- next part -------------- An HTML attachment was scrubbed...

On the other hand, you could simplify the whole above to the following: ### winWidth = FXListBox.new(blk1, :opts => LISTBOX_NORMAL) [800, 1024].each { |w| winWidth.appendItem(w) } winWindth.connect(SEL_COMMAND) do |sender, selector, data| resize(winWidth.getItemText.to_i, height) end ### This could save you some typing and looks (at least to me) more readable. Here "height" is actually a method from FXWindow, which returns the current height of this window''s instance. The same is true for "width", so you wouldn''t need to store the window''s current width in an external variable.

I hadn''t thought to ask the Window for its size, and getItemText is much preferable to the external array. It took a few more type conversions to work, but still is much less code than my earlier solution. ### winWidth = FXListBox.new(blk1, :opts => LISTBOX_NORMAL) ["800", "1024"].each { |w| winWidth.appendItem( w ) } winWidth.connect(SEL_COMMAND) do |sender, selector, data| resize(winWidth.getItemText( data.to_i ).to_i, height) end ### Again, thanks for the suggestions! -- :D -------------- next part -------------- An HTML attachment was scrubbed...
