Closable Property


Object.Closable[ = lExpr]

lExpr

The settings for the Closable property are:

Setting	Description
True (.T.)	(Default) The Close item is added to the window pop-up menu.
False (.F.)	The form cannot be closed by double-clicking the window pop-up menu icon, and the Close item is removed from the window pop-up menu.

Applies To: Form Object | _SCREEN System Variable

The following example demonstrates how the Closable property is set to False (.F.) to prevent a form from being closed using the window pop-up menu or the Close button. If the form's Closable property is set to True (.T.) and the form is closed using the window pop-up menu, CLEAR EVENTS must be issued to stop event processing and exit the program.
