TWinControl.CanFocus function

Member of TWinControlpublicIn unit Controls

Is this control allowed to receive the focus when parent form is visible?

Declaration

pascal

function CanFocus: Boolean; virtual

Description

Checks if the control can get focus when parent form is visible, i.e. if all its parents except the form are visible and enabled.

A possible usage:

if FormFoo.EditBar.CanFocus then
  FormFoo.ActiveControl := FormFoo.EditBar;

CanFocus returns True even if the parent form is not actually visible, and a subsequent SetFocus call could throw an exception. Use CanSetFocus in this case.
