Hi Nathan!

Yes, the Android back button is automatically handled by some app components, which also includes popping pages from the NavigationStack.
Unfortunately, we currently do not yet provide a way to overwrite the default behavior in a convenient way. For that we want to have a well-structured component that handles the back-button and decides which implementation has priority if multiple handlers are defined.

This is already on our roadmap, and there will probably also be a way to define a custom handling within a Page as you suggested.

The inofficial way to add a custom handler to a Page looks like that at the moment:

 

import VPlayApps 1.0
import QtQuick 2.5

App {

  NavigationStack {
    backButtonEnabled: false // deactivate default behavior of navigation stack

    Page {
      title: "Custom BackButton"

      Text {
        id: textItem
        anchors.centerIn: parent
        text: "Press Back Button"
      }

      // handle back button
      Connections {
        target: getApplication()
        onBackButtonPressedGlobally: {
          event.accepted = true

          // do sth here
          textItem.text = "Back Pressed"
        }
      }

    }
  }

}

 

Note: As this is just a connection to the back button press, other components (e.g. a Navigation which opens the first tab on a back press) might steal the back event from the page. So it might be a good idea to just stick with the default behavior until we have a better solution ready. 😉

 

Cheers,
Günther
