Hi List.
I want to know the placement of the caret (in pixels, not character
count) in a TEdit. However i am struggeling to fint a method that will
allow me to do so.
If i try to calculate it using the assigned font, I have the problem
that TEdit.Font.GetTextWidth always returns the default size (16),
since the Font doesn't have a canvas assigned to it.
If you are on windows (and win only), you may be able to use GetCaretPos
https://msdn.microsoft.com/en-us/library/windows/desktop/ms648402(v=vs.85).aspx
(That is, if the edit is focused, and has the caret)
On Windows there is only one caret per App, so if the TEdit has it, then
GetCaretPos should get the pos for that Edit.
Of course win only, and the Edit needs the focus. (And not tested at all)
