Increase in memory usage while using FileDialog qml

Tirupathi Korla

Hi,
We have an application which opens FileDialog on a button click. we are using qml's FileDialog. When we show the FileDialog and closing it by selecting cancel button, we see an increased memory around 1.2MB (in taskmanager) . When we open FileDialog multiple times, the memory is keep going on increasing by 1.2 MB. is it a memory leak?

Hi,

Please provide the version of Qt you are using, the platform and compiler version.

A minimal compilable example showing what is happening would be great.

Hi,
I tested this on Windows Desktop Qt 5.7.1 minGW 32 bit

Here is the code i tested with

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import QtQuick.Dialogs 1.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    FileDialog{
        id:testFileDialog
        onAccepted: {
            console.log("accepted")
        }
        onRejected: {
            console.log("rejected")
            testFileDialog.close()
        }

    }

    Button {
        id: button
        x: 270
        y: 209
        text: qsTr("Button")
    }

    Connections {
        target: button
        onClicked: {

            print("clicked")
            testFileDialog.visible = true
        }
    }
}

Then you should first test on a more recent version. Qt is currently at 5.9.1.
