[Fxruby-users] How do you get the width of a wdiget?

[Rich <ri...@li...>]

When I output the 'width' of a widget I get '1'... I'm assuming that's =
because it's autosized - but then how can I tell how big it is at any =
time during runtime?

I looked through the archives at SourceForge, but none of the subject =
lines seemed to match.

Thanks for any help with such a simple question!

I think I answered my own question - I was asking for the width before =
the window had been 'drawn' (is that the right term?)... so I got '1'.

If I asked for the width after it was drawn, then I got the more =
sensible answer...

[Fxruby-users] reparent/linkAfter in FXFileSelector widget

[Rich <ri...@li...>]

I'm trying to insert my own FXTextField right after the directory drop =
down in the first FXHorizontalFrame... but I've only found the =
'children()' method as the way to navigate through the existing =
structure... and that returns an FXWindow... reparent and linkAfter =
require an FXComposite type as the parameter...

Here's the two different NON-working code attempts:

localVF=3DFXVerticalFrame.new(contentHF,LAYOUT_FILL_X|LAYOUT_FILL_Y)
lfs=3DFXFileSelector.new(localVF,nil,0,LAYOUT_FILL_X|LAYOUT_FILL_Y)
ldTF=3DFXTextField.new(localVF,20,nil,0,LAYOUT_FILL_X)
ldTF.reparent(lfs.children()[0])

...and a different approach...

localVF=3DFXVerticalFrame.new(contentHF,LAYOUT_FILL_X|LAYOUT_FILL_Y)
lfs=3DFXFileSelector.new(localVF,nil,0,LAYOUT_FILL_X|LAYOUT_FILL_Y)
ldTF=3DFXTextField.new(lfs.children()[0],20,nil,0,LAYOUT_FILL_X)
ldTF.linkAfter(lfs.children()[0].children()[3])

What are my options? Is there an easy/easier way to 'insert' something =
into an existing widget like the FXFileSelector?

[Fxruby-users] Why does it return FXRbTextField when I call 'getClassName()' on an FXTextField?

[Rich <ri...@li...>]

Here's the code:

require 'fox'
include Fox
theApp=3DFXApp.new
mainwin=3DFXMainWindow.new(theApp,"Test")
puts FXTextField.new(mainwin,20).getClassName()
theApp.create
mainwin.show(PLACEMENT_SCREEN)
theApp.run

I dunno (maybe it has something to do with the way C++ classes are 
wrapped), but

puts FXTextField.new(mainwin,20).class.name

behaves in an unsurprising way. Hope that helps...

It's returning the name of the underlying C++ class. There's no reason 
for this function to even be exposed to the Ruby interface, just an 
oversight on my part. If you need to know the Class of the Ruby object 
you've got, just use the standard Object#class instead.

The approaches that you're trying are correct, but there is a problem 
with the return values for FXWindow#children. The first child widget for 
the FXFileSelector is supposed to be an FXHorizontalFrame but it's being 
returned to you as an FXWindow instance instead. I know what's wrong, 
but I don't think there's a workaround for FXRuby-1.0.27. I have added 
this to the bug list and it should be fixed in the next release.

Thanks a ton for your response...

I'm really impressed with FOX - until now I haven't really had much hope of
ever being able to code a GUI... this rocks!!
