Is window blank?

[RichardL]

I'm driving an application with AutoIt, I know the coordinates of the window control. I want to know if the area is blank, and no dialogues in front of it. Maybe there's a way with PixelSearch, but I want to know if there is any pixel that is not white. I could checksum the area, and compare with a reference, but the reference number would change with control size.

Thanks.

You mean you want to know if the selected area has no controls inside?

@RichardL

Why not setting the window as topmost or checking its active state?

If not, then you can loop through visible windows and getting their coords in order to know if one of them is over the window.

But I have not understood the blank part...

Br, FireFox.

If it really boils down to pixels, then loop though the control pos (I suggest you use a Step)

with pixelgetcolor and return false if a pixel is not white.

It's a specialised drawing package and it might have been left with some drawings open, i.e. the main window is not all white, and as well as that it might have dialogues open. Yes, JohnOne I could scan all the pixels as you say, but as the mechanism is the same as PixelSearch, but with opposite criteria I was hoping there was a way to do it by simply selecting the right options.

Thanks all.

Have you tried testing ControlgetText()

I know it might not have text, but it's something I'd do on the off chance something is returned

when colours are present.
