Adding stackview qml pages to virtualkeyboard basic example



  • Hi,
    I am very new to qt and qml things...
    I am able to run virtual keyboard example on Raspberry Pi 3 EGLFS QT 5.9...
    It is running perfectly but now I want to add stack view so I can push pop qml pages at event of buttons...so I modified the file basic-b2qt.qml as shown below and have commented out Basic:{} part and instead inserted stack view and after loading basic-b2qt.qml pushed "Basic.qml " page on stack..and it was showing perfectly on my raspberry pi screen 7" but auto scrolling is disabled by changing this ..so when I touch text field at bottom of screen and type on virtual keyboard the text field stays there behind keyboard ...before adding stack push like this it was auto scrolling up to top edge of keyboard.

    Whole project files same as example just made this changes in basic-b2qt.qml file...

    I don not know about qt qml much just started learning... if this way is wrong how to do it..any suggestion .

    Thank you.

  • Changed this but issue still remains ...any suggestion about this..........

    StackView{
                id: stackView
                focus: true
                ayout.fillWidth: true
                Layout.fillHeight: true
                anchors.top: parent.top
                anchors.bottom: inputPanel.top
    
            }
    


  • got expected output....
