How to determine mouse coordinates in delphi?

Question

Delphi

In general, I need to determine the mouse coordinates and write them to the label.
In the mouseMove event I write

Form1.label4.caption := 'X = ' + IntToStr(X) + ' : ' + 'Y = ' + IntToStr(Y);

But nothing happens. How to fix the code so that everything works?

Answer 1

And some panel or something else that does not lie in the whole form? Your line will only work when the mouse is moving directly over the "naked" form.

Answer 2

Should only work within a form!
