Replace quitting behaviour

[fleimeris]

Hello,

I would like to ask if it's possible to replace behavior of quitting application or get a signal whenever application quit is requested ?

In source code I can see that it just does RequestStop (); but maybe I'm missing something:

Terminal.Gui/Terminal.Gui/App/Application.Keyboard.cs

Lines 217 to 225 in b3aa9c5

	AddCommand (
	Command.Quit,
	static () =>
	{
	RequestStop ();
	return true;
	}
	);

Thank you in advance.

You can do it like this

https://github.com/gui-cs/TerminalGuiDesigner/blob/v2/src%2FUI%2FEditor.cs#L905

Or, at the Application level you can subscribe to Application.NotifyStopRunState, although unlike Toplevel.Closing, this event can't be cancelled.

Or, ...

You can call Application.KeyBindings.ReplaceCommands and replace the default logic for Command.Quit. However, this will not catch cases where some other part of your code directly calls RequestStop.
