MessageDialog in QML

Adrian.Aioanei

Hey again to all :D

I am back with a little problem.:D
I want to create a MessageDialog in QML.
I have found this in Qt documentation (Qt doc).

And if i try to run this example:

import QtQuick 2.2
import QtQuick.Dialogs 1.1

MessageDialog {
    title: "Overwrite?"
    icon: StandardIcon.Question
    text: "file.txt already exists.  Replace?"
    detailedText: "To replace a file means that its existing contents will be lost. " +
        "The file that you are copying now will be copied over it instead."
    standardButtons: StandardButton.Yes | StandardButton.YesToAll |
        StandardButton.No | StandardButton.NoToAll | StandardButton.Abort
    Component.onCompleted: visible = true
    onYes: console.log("copied")
    onNo: console.log("didn't copy")
    onRejected: console.log("aborted")
}

Doesn't give me any error but when i use this in main :

    QQuickView view;
    view.setSource(QUrl("qrc:/window.qml"));
    view.show();

Popup a empty window.
And what is more strange is when i run, popup tow window and i don't understand why.
Is there another way or maybe the correct way to use MessageDialog ?

I think your code give you an error like this:
"QQuickView only supports loading of root objects that derive from QQuickItem.
Ensure your QML code is written for QtQuick 2, and uses a root that is or
inherits from QtQuick's Item (not a Timer, QtObject, etc). "
So you need put your MessageDialog to e.g. Item wrap like this:

import QtQuick 2.2
import QtQuick.Dialogs 1.1
Item{
MessageDialog {
    title: "Overwrite?"
    icon: StandardIcon.Question
    text: "file.txt already exists.  Replace?"
    detailedText: "To replace a file means that its existing contents will be lost. " +
        "The file that you are copying now will be copied over it instead."
    standardButtons: StandardButton.Yes | StandardButton.YesToAll |
        StandardButton.No | StandardButton.NoToAll | StandardButton.Abort
    Component.onCompleted: visible = true
    onYes: console.log("copied")
    onNo: console.log("didn't copy")
    onRejected: console.log("aborted")
}
}

And It should work now.
And in main use only:

QQuickView view;
view.setSource(QUrl("qrc:/window.qml"));

Yes, now works fine.
