Message XbpWindow():xbeP_Quit Foundation

Application will be terminated.

:quit := {| nCause, nConfirm, self | ... } --> nConfirm
:quit ( <nCause>, <nConfirm> ) --> self
The parameter indicates the cause of a program termination. It is a numeric value for which #define constants exist in the XBP.CH file. These constants are prefixed with XBP_QUITCAUSE_*.
The second parameter is used to confirm a program termination. The following #define constants can be used as valid values:
Constants for the second parameter
Constant Description
XBP_ALLOW *) Program may be terminated
XBP_REJECT Program must not be terminated
  1. Default

The code block must return a numeric value represented by a #define constant that is valid for <nConfirm>.

This method returns the object executing the method (self).


The parameter <nConfirm> determines whether or not a program may be terminated. If a code block is assigned to the instance variable :quit, it must return a valid value for <nConfirm>. When the :quit() method is overloaded, the super class's method must be called with a valid value for the second parameter.

The xbeP_Quit event is generated when an Xbase++ application is terminated by its process being deleted from the task list. The task list is displayed by pressing the key combination Ctrl+Esc. It contains the titles of all windows where processes are active. Processes within the task list can be terminated by pressing the Delete key. If an Xbase++ application is terminated in this manner, the xbeP_Quit event is generated to which a reaction can be made.

On Windows platforms, the xbeP_Quit event is only generated upon system shutdown. That means, Windows does not generate an xbeP_Quit event when a program is terminated from the Task Manager. Instead, an xbeP_Close event is created. Only when a running process is about to be killed by the operating system's shutdown procedure does the program receive the xbeP_Quit event.
