Qt Quick Controls 2 - How to grab the items contained in a TableView in images in order to print them?

[jeanmilost]

I need to print the whole content of a TableView. How can I grab its items in images in order to print them?

I tried the following code, but no way, this doesn't work:

QList<QObject*> objects = m_pEngine->rootObjects();
QQuickItem*     pItem   = qobject_cast<QQuickItem*>(objects[0]->findChild<QObject*>("gvMessageGrid"));
    
if (pItem)
{
    QImage pImage = pItem->grabToImage()->image();
    ...

The above code always return an empty image.

For info, here is the qml code for my TableView:

/**
* Grid view item
*/
Component
{
    id: itGridItem
        
    Item
    {
        width: gvMessageGrid.width
        height: itemTextID.height + 40
        
        Rectangle
        {
            property int messageWidth: (gvMessageGrid.width / 2) - 50
        
            id: itemRect
            x: senderIsMyself ? 25 : gvMessageGrid.width - (25 + messageWidth)
            y: 5
            width: messageWidth
            height: itemTextID.height + 20
            color: senderIsMyself ? "#d5d5d5" : "#800b940e"
            radius: 5
            clip: true
        
            Text
            {
                id: itemTextID
                width: parent.width - 20
                text: itemText
                renderType: Text.NativeRendering
                textFormat: Text.StyledText
                wrapMode: Text.WordWrap
                font.family: "Segoe UI Emoji"
                font.pixelSize: 18
                anchors.margins: 10
                anchors.left: parent.left
                anchors.top: parent.top
                color: "#101010"
            }
        }
    }
}
        
/**
* Messages grid view
*/
ListView
{
    id: gvMessageGrid
    objectName: "gvMessageGrid"
    y: 0
    Layout.fillHeight: true
    flickableDirection: Flickable.VerticalFlick
    Layout.fillWidth: true
    Layout.alignment: Qt.AlignHCenter | Qt.AlignVCenter
    clip: true
    contentWidth: 700
    contentHeight: 300
    model: lmGridModel
    delegate: itGridItem
        
    ScrollBar.vertical: ScrollBar
    {
        visible: true
        minimumSize: 0.1
    }
}        

An important note: Please don't provide solutions involving Qt Quick Controls 1.x. I cannot use them, as they contain too many severe performance issues, and they aren't DPI aware. My company rejected them, so it's not a solution for me. Only Qt Quick Controls 2.0 are accepted.
