How to get the control under the mouse cursor in onMouseDown event?

Question

I have a TGridLayout filled with some images in a Firemonkey HD Application. In the gridLayout's onMouseDown event I want to get the image object on which the user has clicked, but I have only mouse coordinates.

Implementing onMouseDown event for every image is not an option, because if an image is removed from the gridlayout an empty space remains. In this case I also want to know if the user has clicked in this empty area.

Is there a some kind of "getChildAtPos" or "FindVCLWindow" analog in Firemonkey?

Thanks!

TForm.ObjectAtPoint should do the trick.

ha ha. Emba had to rename the function because it contained VCL in its name :) – Gabriel Mar 02 '23 at 08:38

FindVCLWindow does what you need. You need to specify the point at which the control is, in your case it's mouse position.

My fault also :) I refined the question so it's clear now it's about Firemonkey Application. – iPath ツ Oct 08 '12 at 13:37
