Custom main frame close

Postby jvxdev » Fri Mar 04, 2016 4:43 pm

I won't close the application if x button was pressed. How is this possible?

This depends on the UI implementation.

If you use Vaadin UI, it can't be done because JVx can't change the browser handling.
If you use Swing UI, it's easy because the launcher is the frame:

Code: Select all
getLauncher().eventWindowClosing().addListener(this, "doWindowClosing");

If you add a listener to the event, the default implementation will be completely ignored.

Don't forget to call:

Code: Select all

in your listener, to close the frame, if needed.
