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.

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