Hello, world!

How does one go about changing the style of a button after it has  
already been made? Or if there is none, is there some way to highlight  
a button? The button can’t be a ToggleButton, it must be a  
BitmapButton.

Thanks!

I’m not sure exactly what you mean by style - if you just mean the  
bitmap that is shown, you can use set\_bitmap\_label (and also other  
set\_bitmap\_xxx methods for other states like hover, focus) to change the  
image that’s displayed. Using set\_bitmap\_focus and set\_bitmap\_selected  
will automatically deal with highlighted images for those states - you  
don’t need to managed this yourself.

If you need to change the formal “style” argument (eg Wx::BU\_AUTODRAW)  
then you have to swap two different widgets in and out, and show and  
hide them.
