On the theory that the mouse can only interact with one element on the screen at
|
|
|
|
|
a time, there's no need for every element to always define its own highlight.
|
|
|
|
|
|
|
|
|
|
rematch:ShowTextureHighlight(texture) will parent a shared frame to the texture's
|
|
|
|
|
parent, then make the frame's texture the same as the given texture, but with
|
|
|
|
|
alphaMode "ADD", causing the texture to light up.
|
|
|
|
|
|
|
|
|
|
Use rematch:HideTextureHighlight() to remove it.
|
|
|
|
|
|
|
|
|
|
CompositeButtons use this method to highlight its textures, but with its own frame.
|
|
|
|
|
|
|
|
|
|
TODO: Make CompositeButtons use this instead and add UpdateTextureHighlight to
|
|
|
|
|
the postUpdateFuncs of its scrollframes.
