DataWindow.QueryClose Method

X#
Provide a method that is invoked just before the data window closes to confirm if the application really wants to close the window.

Namespace:  VO
Assembly:  VOGUIClasses (in VOGUIClasses.dll) Version: 2.21
Syntax
Copy
 VIRTUAL METHOD QueryClose(
	oQCE
) AS USUAL CLIPPER
Request Example View Source

Parameters

oQCE (Optional)
Type: Usual
The Event object that describes which data window is about to be closed.

Return Value

Type: Usual
TRUE if the data window is to be closed; otherwise, FALSE.
Remarks

Tip Tip
Important! This is a callback method used by X#. Normally, it should not be called in your application code.
Tip Tip
If you reimplement this method in your subclass, it is recommended that you first call SUPER:QueryClose() within the method to obtain its default behavior.
When a user tries to close an application by selecting the Close menu command from a system menu (or by using another method to end the session), the system calls each data window's QueryClose() event handler.
