Is it possible to bring a control on top of other.

For example:


If I want to make Control2 to stay on top of control1.

Your question doesn't make sense to me.

When you write "top", which dimension are you referring to?

Some refer to "top" as the y position further from the floor
Some refer to "top" as z-order, so the iterm covers another control

I have changed you script to show that the 2nd control is layered on top of the first.

I know of 3 ways to keep one control drawn on top of another (and still be part of the same gui).

First is to redraw the upper control immediately whenever the bottom control is redrawn, you can do this by monitoring the WM_NOTIFY message.

Second is to use SetParent to make the upper control a child of the lower control.

Third is to use WinSet, Region, to cut a 'hole' in the lower control to allow the upper control to show through, regardless of what order they're redrawn in. (Also, setting controls' display regions can produce effects like graphically joining separate edit controls).

Yes, sorry I am talking about their zindexing.

Thanks VxE, I will try out these techniques and see which one works best in my situation.
