TWinControl.CanSetFocus function

Declaration

function CanSetFocus: Boolean; virtual

Description

Checks if the control can receive focus, i.e. if all its parents are visible and enabled.

A possible usage:

if MyControl.CanSetFocus then
   MyControl.SetFocus;

CanSetFocus should be preferred over CanFocus if used in CanSetFocus/SetFocus combination because it checks also if the parent form can receive focus and thus prevents the "cannot focus an invisible window" LCL exception.
