How to make an imagebutton with focus mask but for transparent buttons?

[searchwindows]

I understood that focus_mask =True will allow non-transparent area to be selected.

For example,

Code: Select all

Screen kitchen:
	add "kitchen_bg.jpg"
	imagebutton:
		hover "apple_hover.png" focus_mask = True action Null
		idle  "apple_idle.png" focus_mask = True action Null

This will make the apple function with idle and hover as long as the cursor hovers over the non-transparent part of the apple_idle.png.

But if theres already an apple on kitchen_bg.jpg, and you create ANOTHER apple as apple_idle.png for idle imagebutton, that mean's the apple from kitchen_bg.jpg is overlapped by the apple_idle.png idle image and is no longer shown. How do I make it so that the apple from kitchen_bg stay, and still make apple_idle work if I made it transparent?

Your problem is the action Null and the =

Code: Select all

	imagebutton:
                focus_mask True 
                action NullAction()
		hover "apple_hover.png" 
		idle  "apple_idle.png"

I found a workaround by using a transparent image for idle.png
and defining a focus_mask image as the apple.png.

If there is a simpler way to do this, I'm all ears!
