fxruby users - Apr 2005 - Available layout options?

How can I dynamically figure out all of the available layout options
for any given widget.

I can scrape the RDocs for options available to just that widget, but
each widget inherits more from the hierarchy - right?

Well, if by "dynamically figure out" you mean some sort of method you 
can call on an object at runtime, there''s no way to do that; you 
definitely have to consult the documentation.

You are correct that the options (layout and otherwise) available for a 
particular widget include all of the options available for objects of 
its ancestor classes. For example, a label (an instance of the FXLabel 
class) has certain label-specific options (e.g. how the text is 
justified inside the label, or how the label''s text is positioned 
relative to the label''s icon), but since FXLabel is a subclass of 
FXFrame, you also have the frame decoration options at your disposal 
(e.g. sunken or raised frames, frame thickness, etc.)

Yes, the FXRuby classes'' inheritance chain is the same as that for the 
FOX classes.

Sure, that should work. You might also be able to write a clever little 
Ruby program to figure it out for you since you can ask Ruby classes 
about their superclass, e.g.

	superclassOfLabel = Fox::FXLabel.superclass # should return 
Fox::FXFrame

Anyways, hope this helps,

Hello list,

I''m having trouble getting hotkeys to work in FXRuby. For my app, or
at least a window, can I define a global hotkey for it so that I could
,say, press F5 and run some function? I''ve messed with FXAccelTable
and looked all over the place, but I still can''t get them to work.
Anyone have a working example?

Thanks.

See ya,

The datatarget.rb program in the "examples" directory of the FXRuby 
distribution provides one such example. Take a look around line 175:

	# Install an accelerator
	self.accelTable.addAccel(fxparseAccel("Ctl-Q"), getApp(), 
FXSEL(SEL_COMMAND, FXApp::ID_QUIT))

and change the text in the call to fxparseAccel() to some other 
accelerator key, e.g.

	self.accelTable.addAccel(fxparseAccel("F5"), getApp(), 
FXSEL(SEL_COMMAND, FXApp::ID_QUIT))

This says that when the user presses the F5 key, the accelerator table 
will send a message with type SEL_COMMAND and identifier FXApp::ID_QUIT 
to the application object (which is returned by the call to getApp). In 
your case you''ll probably want to send some other message to some other
object.

Hope this helps,

Lyle
