Application memory increases a lot with a FileDialog: Using Loader this memory is not free

  • Hi,

    I have a simple QML application where I open a FileDialog when a button is pressed.

    I have realized that when I open the FileDialog the current application memory is increased a lot (12 Mb only with the dialog), so I have added a Loader to the FileDialog. Therefore, the memory is only increased when I open the dialog. But my problem is that I can not free this memory, even setting the Loader source to "".

    My test file:

    import QtQuick 2.0
    import QtQuick.Controls 1.4
    Item {
        width: 400
        height: 400
        Loader {
            id: loaderFileDialog
        Connections {
            target: loaderFileDialog.item
            onAccepted: {
                loaderFileDialog.source = "";
            onRejected: {
                loaderFileDialog.source = "";
        Button {
            anchors.centerIn: parent
            width: 100
            height: 50
            text: "Open file";
            onClicked: {
                loaderFileDialog.source = "qrc:/MyFileDialog.qml";
                loaderFileDialog.item.visible = true;

    And my QML file with the FileDialog: MyFileDialog.qml

    import QtQuick 2.1
    import QtQuick.Dialogs 1.0
    FileDialog {
        id: fileDialog

    What am I doing wrong? Any idea or suggestion?

    Thanks a lot in advance,
