  3. QTBUG-112475

StackView operations (which take QQmlV4Function* args) cannot be compiled by qmlsc

    • 7d0ec8910 (dev), 1baa7fc3e (dev), 3e619367b (dev)

      These functions don't seem to be compilable:

      Q_INVOKABLE void push(QQmlV4Function *args);
Q_INVOKABLE void pop(QQmlV4Function *args);
Q_INVOKABLE void replace(QQmlV4Function *args);

       

      Code

      import QtQuick
import QtQuick.Controls.Basic

Window {
    width: 640
    height: 480
    visible: true

    StackView {
        id: stack
    }

    Component {
        id: comp
        Rectangle{}
    }

    function pushOne(): void {
        stack.push(comp)
    }
    function popOne(): void {
        stack.pop()
    }
    function popOneWithoutTransitions(): void {
        stack.pop(StackView.Immediate)
    }
    function popAll(): void {
        stack.pop(null)
    }
}
