DESTROYFLAG property (Window)

Specifies if the window is flagged for destruction during QUERYEND processing.

This is a Boolean property.

When the SYSTEM QUERYEND property returns TRUE$, windows that are destroyed will have DESTROYFLAG set, but the windows themselves will not be destroyed.

Often, the HANDLE property is used to test if a window still exists, but if a window is closed (by using End_Window() for example) when QUERYEND is true, the HANDLE will still exist but DESTROYFLAG will be set.

In earlier versions of OpenInsight this property was called DESTROY_FLAG. This name is deprecated but can still be used.
