How to disable user interaction on widget

[sonoro1234]

Hi,

I have a curve widget and show three of them (one for each RGB channel)
As they are quite big I am rendering them all at the same CursorScreenPos so that you can see them all because of transparency.

When user interacts only the topmost of them should respond.
How can achieve this

Now I am solving this drawing first the curve I want to interact with. The problem is that it appears not at the top but at the bottom!

draw it again last?

[sonoro1234]

Yes but is an expensive widget!

I am using ratcherfreak proposal. Perhaps BeginDisabled()/EndDisabled(); proposal in #211 would be the way.

Closing as duplicate. @sonoro1234, see #211 for beginning of a solution.
