Hi

How to catch android back button in application?

With ApplicationWindow I have onClosing signal

With VPlay Games there is onBackButtonPressed

But how about VPlayApps ? I have tried this code but it seems no key events are received inside Page or Rectangle

            focus:true
            Keys.enabled: true
            Keys.onPressed:{
                console.debug("back key")
            }
            Keys.onReleased: {
                console.log("back key")
            }
            Keys.onBackPressed: {
                console.log("back key")
            }

Particulary with Page and “backNavigationEnabled: false” which is good when user is already logged in (can’t go back to login page), but then I can’t close the app

Best Regards

ok part of the problem is solved.

When I set navigationBar.backButtonVisible:false inside NavigationStack (instead of backNavigationEnabled: false in loggedPage) the effect is the same – user cannot go back from loggedPage to loginPage but android back key is closing the app, but still how to catch onClosing or something similar to display close dialog ?

Hi,

The App type also supports a signal onBackButtonPressed, which you can use (it’s missing in the docs/auto-completion, as we intend to improve custom back button handling within Felgo Apps in the future):

App {
  onBackButtonPressedGlobally: {
    event.accepted = true

    // do sth here
    console.log("BACK PRESSED")
  }
}

Best,
Günther

Hi

Yeah, it works!

onBackButtonPressedGlobally: {
        if(mainNavigation.currentIndex==0) {
            event.accepted = true
            console.log("BACK PRESSED")
            Qt.quit()
        } else {
            event.accepted=false
        }
}

Best Regards

Any improvements about custom back button handling? Is there a possibility to handle back button in Page component, not globally?

Hi Pawel,

we will introduce improvements to the back button handling with the next update. This will allow you to e.g. stop a specific page from popping and instead handle the back button event yourself inside this page.

Best,
