    Hello everyone.

    My question is how to prevent a Dialog from closing when android’s back button is pressed. I tried using connectors targeted to the Application and listening for BackButtonPressedGlobally, but no luck. What I want to achieve is a modal dialog box, which cannot be dismissed – either positive or negative action must be chosen.

    Hi Dauren!

    There are currently two ways to show dialogs:
    Either with the QML based InputDialog component, or by using a NativeDialog.

    Unfortunately, both dialogs do not support disabling the back button handling at the moment. When showing a native dialog, the back button button is not handled by QML and always dismisses the dialog. The QML based Dialog handles the back button from within QML, so it would be possible to interrupt this by consuming the back pressed event before the Dialog can handle it.

    Have you tried adding:

          Connections {
            target: getApplication()
            onBackButtonPressedGlobally: {
              console.log("back button pressed")
              event.accepted = true // consume the event so other components, like the dialog don't handle it

    to your QML code?





    I’ll give it a shot, and let you know. Thanks, Günther.



    So, it does work when

    event.accepted = true

    is specified. Apparently, I missed this bit when I tried for the first time.
