Delete last character in a string

[Gaurav Chopra]

How can I delete a last character from a string ?

[sierdzio]

QString string("abc");
string.chop(1);

https://doc.qt.io/qt-6/qstring.html#chop

Or, if you prefer const solution:

const auto shorter = QString("abc").chopped(1);

@sierdzio Giving error in line 8 ->

Expected token `,'

import QtQuick 2.0

Rectangle {
    height: 480
    width : 800
    color : "black"

property QString string("abc")

MouseArea{

    anchors.fill: parent
    onClicked:{
        string.chop(1);
        console.log(string)
    }

}

}

Ah, you mean in QML, you should have said so :-)

In this case you need to look at JavaScript docs for strings. Maybe this will work:

property string str: "abc"
onClicked:{
        str = str.slice(0, -1);
        console.log(str)
    }
