Window.CancelClose

From Xojo Documentation

Event


Window.CancelClose(appQuitting as Boolean) As Boolean

Supported for all project types and targets.

The window is about to be closed by the user clicking the close button, by calling the Quit or Window.Close methods.

Notes

When the application is quitting, CancelClose and Close are called as a pair for each open window. Close will be called after CancelClose executes, assuming that the close wasn't canceled by the user.

Return True to prevent the window (and in the case of the Quit method, other open windows) from closing. The parameter appQuitting is True when the window is being closed because the whole application is quitting and False when only the window is being closed.
