how can i add an animation (.gif) on a button on press?
for example a button that disappear on left border
no, look at ResourceImageSet in xml's
i must add animation directly here?
i don't understand how can i add animation, when i create animation (gif image or other format) where i must tell to program that on push property of the button it must show me the animation?
Copy every frame from animation file to new image in external editor.
Use ResourceImageSet for switch frames in new image.
