mouse.button with switch-case

hslee_6560

Hi, I tried to use switch-case with mouse.button but, it seems that doesn't work.

I want to know the reason.

Why It doesn't work?

MouseArea {
    anchors.fill: parent
    acceptedButtons: Qt.AllButtons
    // ...
    onPressed: {
        property string buttonID = 'Nothing'

        switch (mouse.button) {
        case Qt.LeftButton: buttonID = 'LeftButton'; break;
        case Qt.RIghtButton: buttonID = 'RIghtButton'; break;
        }
        test.text = 'pressed ' + buttonID
    }
}

I found it works whether I use if-else not switch-case.

I can not understand what is the difference between two of them.

Please, Let me know.

Thank you! :)

ps. I missed something like 'break' or 'acceptedButtons' ... but it were there when I found the problem, and I edited them. sorry.

I am really sorry, It turned out my fault.
I wrote wrong spell " switch (mouse.botton) { ..."
now it works.
Thanks all your comments.

hi,
@hslee_6560 said in mouse.button with switch-case:

onPressed: {
property string buttonID = 'Nothing'

you can not write QML inside js block

declare your buttonID like you declare js variable , not QML property

  onPressed: {
        var buttonID = 'Nothing'

Beside of a lot of syntax mistakes you are using switch in a wrong way. Add break at the end of each case block.

switch (mouse.button) {
case Qt.LeftButton: buttonID = 'LeftButton'
case Qt.RIghtButton: buttonID = 'RIghtButton'
}

The acceptedButtons value for MouseArea is Qt.LeftButton

To indicate that all possible mouse buttons are to be accepted, the special value 'Qt.AllButtons' may be used.
Refer: acceptedButtons : Qt::MouseButtons.

MouseArea { acceptedButtons: Qt.AllButtons }

Please check for the Spelling & Syntax

    MouseArea {
        property string buttonID: 'Nothing'

        anchors.fill: parent
        acceptedButtons: Qt.AllButtons

        onClicked: {
            switch (mouse.button) {
            case Qt.LeftButton: buttonID = 'LeftButton'
                break;
            case Qt.RightButton: buttonID = 'RightButton'
                break;
            }

            textEdit.text = 'pressed ' + buttonID;
        }
    }

All the best.
