Determining the coordiante position of a certain gui item

So, not sure if you are asking about the clicking AND the position or just the clicking.  If you can find the component via NameMapping, etc., then there are properties of the component that indicate pixel position.  Top and Left are the pixel locations of the object relative to the parent object.  Then "height" and "Width" will tell you the size of the object.  ScreenTop and ScreenLeft give the position of the object relative to the entire visble screen.  Using some combination of ScreenTop and ScreenLeft with Height and Width should be able to give you the necessary values to put together a drag function.

Hi Mehdi,

In addition to everything suggested by others, you may also talk to developers and ask them to include debug information for the TLogGrid as described here: https://support.smartbear.com/testcomplete/docs/app-testing/desktop/delphi/preparing/compiling-delphi-xe6-xe8-and-10-applications-with-debug-info.html

Then you should be able to get every TLogGrid's line in the Object Browser and be able to operate its absolute and relative coordinates.

Have you tried to add the TLogGrid class to the standard TStringGrid of supposed application developpment langage ? To access to its internal properties.

For knowing the caret position it's simple with win 32 api, function getCaretPos:

To use it in TestComplete:

You can also use Sys.Desktop.MouseX and Sys.Desktop.MouseY to know the coordinate of the mouse, but you must find a way that the mouse is on the corrrect field.
