SwipeView and TabBar currentIndex issue when dynamic object creation

nsourl

Hi,

I am using Qt 5.15.0 and trying to load some tabs dynamically on SwipeView before using it on my project. But unfortunately, I am facing an issue with currentIndex of SwipeView and TabBar that it doesn't increment at all. So, the Rectangle area will remain always red instead of switching colors between red and green.

Am I doing something wrong with my QML example? Am I missing something how to connect SwipeView and TabBar? Please check my QML example below.

Thanks!

import QtQuick 2.12
import QtQuick.Controls 2.12

ApplicationWindow {
    width: 640
    height: 480
    visible: true
    title: qsTr("Tabs")

    Component {
        id: resultListView
        Rectangle {
            color: "blue"
        }
    }

    Component {
        id: tabButton

        TabButton {
            width: implicitWidth
        }
    }

    SwipeView {
        id: swipeView
        anchors.fill: parent
        currentIndex: tabBar.currentIndex
    }

    footer: TabBar {
        id: tabBar
        currentIndex: swipeView.currentIndex
    }

    Component.onCompleted: {
        for (var i = 0; i < 5; i++) {
            console.log("tabBar currentIndex: ", tabBar.currentIndex)
            console.log("stack currentIndex: ", swipeView.currentIndex)

            // Add TabButtons dynamically on TabBar
            tabBar.addItem(tabButton.createObject(tabBar, {text: qsTr("tab - " + (tabBar.count))} ) )

            var col = "green";
            if (tabBar.currentIndex % 2 === 0) {
                col = "red";
            }

            console.log("tabBar color: ", col)

            swipeView.addItem(resultListView.createObject(swipeView, {color: col}))
        }
    }
}

Hi @nsourl ,

Please consider using count (total number of items) instead of currentIndex property:

            if (tabBar.count % 2 === 0) {
                col = "red";
            }

Hi @ndias ,

Indeed, using count instead of currentIndex solved my issue.

Thanks!
