PtUnrealizeWidget()
Unrealize a widget
Synopsis:
int PtUnrealizeWidget( PtWidget_t *widget );
Library:
ph
Description:
This function unrealizes the specified widget and all its children: the widgets are removed from the display, and the widget engine will no longer invoke their callbacks.
Unrealized widgets still exist in the widget hierarchy and can be realized again.
 |
Unrealizing and realizing a widget can take some time. If you want to hide a widget quickly, you can set its Pt_ARG_POS to a very negative value. You should also set Pt_BLOCKED in its Pt_ARG_FLAGS so the widget won't get focus. |
Returns:
- 0
- Successful completion.
- -1
- An error occurred.
