TWinControl.RemoveFocus procedure
Notifies the parent Form when the control cannot be focused.
Declaration
procedure RemoveFocus(Removing: Boolean)Arguments
Removing | True if the control is being freed, False when it is not enabled or not visible. |
Description
RemoveFocus is a method used to notify the parent form when the
control cannot be focused. RemoveFocus is called from methods like Destroy
and RemoveControl, where the control will no longer exist on the parent form.
It is also called from methods like CMEnabledChanged and CMVisibleChanged,
where the parent form should no longer allow the control to be focused.
RemoveFocus calls GetParentForm to get the parent form instance, and calls its DefocusControl method to ensure that the control is removed as the ActiveControl (when assigned).
