Exit app from menu on control in Tab [message #58131]

I want to exit the app from a menu-item on an ArrayCtrl::WhenBar-handler in a TabCtrl in the main window.

I am using

bar.Add("Exit", [&]{ Break(); }); --- bug - assertion fails

I also tried

bar.Add("Exit", [=]{ Break(); });

but get same error

What is the right way to do so?

Hi

This is how I do

	bar.Add ( t_ ( "Exit" ), [=] { Exit(); })
	.Help ( t_ ( "Exit the application" ) );

And Exit() function.

void mainclass::Exit()
{
	Close();
}

Warm Regards

Deepak

Thanks for the suggestion.
Unfortunately does not work either, and/but I don't get any error-message either, it just does nothing.
(I tried it before with overriding 'Close()' in the mainclass as well)

I debug-traced the execution-calls, it follows:
TopWindow::Close()
Ctrl::IgnoreMouseUp()
Ctrl::Close() - which it completes to '... popup = false; }'
(and then seems to go on with standard Upp processing, I think)
and then nothing happens, the app still runs.

I tried with & without GuiLock __; and also in Release-mode - still fails to close the app
(the app needs to close in a controlled way because a class needs to update a db on dtor)

Hi Slashupp,

Check GeoFun from example folder of UPP.

It may be available other places also.

Warm Regards

I checked GeoFun just now...
(It works in my app if put an arrayctrl directly in the mainclass) BUT ...
The big/main difference is that I've got a TabCtrl(several tabs) and in a tab there
is a ArrayCtrl as child. It is from the popup-menu on this child arrayctrl that I want to
be able to close the app. I use a pointer to the main-class instance where the Exit()(or /Close())
method is defined to make the call from the lambda. This is what fails.

Hello slashupp

Have you tried posting a callback to the main window/loop. (e.g. using PostCallback([&] { Break();} ) method) ?

Best regards,

Hi Oblivion

Doing 'PostCallback([&] { Break(); })' does not work.
but when I replace the call to Break(); with a call to the Exit(); from deep's answer it works!
'PostCallback([&] { Exit(); })' - works! Smile

Thank you
