GetCursorPos

[Middlecope]

On a form I have a Paintbox.
On the Canvas of the Paintbox I draw an Ellipse(x1,y1,x2,y2)
If I click inside the ellipse in the PaintboxOnClick I state GetCursorPos(p).
Unfortunately the  p.X and p.Y are outside the ranges [x1..x2] and [y1..y2]
Does anyone has an idea what I do wrong?
Thanks for your attention

AFAIK GetCursorPos returns cursor's global position (i.e. relative to the screen, not your application nor the specific control). Try calling ScreenToClient method from the specific control (TPaintBox in your case).

Alternatively you can declare variables mouseX, mouseY, and update their values in PaintBoxOnMouseMove event, by X, Y parameters.

Or even easier by using onMouseDown (or onMouseUp) event instead of onClick. You have those cursor coordinates passed as X, Y there too.
