Is it possible to create a hidden button?

[joethezombie]

I wish to create a hidden button. One that is only visible when the mouse is hovering over the control. The problem is VLC will not show the over="example.png" image if the up="transparent.png" image is completely transparent. In fact, the control can only be operated on visible pixels.

Is there a way to allow the control to be operated even though it is transparent?

You can use the part of the background image which is behind the button, for the "up" state.

Unfortunately, the background image changes depending on certain variables, but I altered the skin to compensate. Not what I wanted to do, but it works.
