Hello Ive been playing around with ruby Tk to build a UI for a few new  
music ruby apps I was wondering if anyone knew how to get a image to  
display for a button? Ive looked around but didn’t find any real world  
examples

Thanks Gabriel

## Please create a TkPhotoImage object and ‘image’ option of button widgets. For example,

## img = TkPhotoImage.new(:file=\>your\_image\_file\_name) btn = TkButton.new(base, :image=\>img).pack

See the Ruby/Tk WidgetDemo (ext/tk/sample/demos-en/widget on a Ruby  
source). It includes examples of label widgets with a image.  
TkButton class is a subclass of TkLabel.  
So, same ways are available for button widgets.

Standard Tcl/Tk can support only GIF and PPM/PGM formats.  
If you want to use other formats (BMP, JPEG, PNG, and so on),  
you must use TkImg extention (ActiveTcl package includes TkImg  
extension).

When “require ‘tkextlib/tkimg’” returns true,  
your Ruby/Tk (Tcl/Tk) has TkImg extension.  
Otherwise, you must install TkImg extension for your _Tcl/Tk_  
libraries which used by Ruby/Tk.
