Re: [Fxruby-users] Icons and tooltips

[Jamey C. <jc...@tw...>]

I'm sure others, especially Lyle, can anwer these questions better than 
I can, but since we all want Lyle to be working on the next version of 
FXRuby instead of answering questions, I'll take a lame stab at some 
answers:   :)

FXPNGIcon.new isn't putting the icon into any particular widget, it is 
simply creating the icon so that it can later be put into one or more 
widgets or windows (i.e. button, dialogbox, etc.).  That's why you don't 
specify the particular widget (i.e. button) when you initially create 
it.  However, if you look in the docs for the FXButton class, you will 
see that you can specify an icon in the constructor.  That's where you 
put the reference to the FXPNGIcon that you created earlier.   Am I 
understanding the question or did I miss something?

This is kind of the same thing.  You initialize a FXTooltip object once 
for the entire application.  Then, when you create each object (i.e. 
button), you can specify a text string in the constructor that will 
appear as the tooltip for that object.  But you have toe create the 
FXTooltip first for the whole app in order for tooltips to work for each 
object.

A pretty good source for docs is at www.fxruby.org.  Click on the "API" 
button.  This will take you to definitions of all the FXRuby 
classes/methods/attributes.

HTH.
