protected procedure TCustomComboBox.DestroyWnd; override; |
DestroyWnd is an overridden method in TCustomComboBox used to destroy the handle for the windowed control. This occurs when the control is freed, and when the handle is re-created in the widgetset class. DestroyWnd ensures that values for the ItemIndex and Items properties are retrieved from the widgetset class before it is destroyed or re-created. The value in Sorted is applied to the Items retrieved from the widgetset class.
DestroyWnd calls the inherited method prior to exit.
DestroyWnd calls RaiseGDBException to raise a catchable debugger exception if a handle has not been allocated for the control.
