[Lazarus] Measuring text width in a TEdit

[Vojtěch Čihák]

Hi,
 
maybe you can create some temporary canvas, assign TEdit.Font to TCanvas.Font, do the measurement and free that canvas.

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.
 
 The TEdit itself does not really have any methods for calculation the 
 caret position in pixels either.
 
 All suggestions are welcome. :)
 
 
 Kind regards,
 Torsten Bonde Christiansen.
