Including MessageDialog

[ssudhindrarao]

HI,

I am using Qt5.2, i have a user input QML screen in which the user will fill form and submit.

On Submit, i want to do the validations using the javascript function and if there is any error then show it as a popup.

Can anyone please give a sample of how i can trigger the MessageDialog from the javascript function.
And also i am not able to create a MessageDialog component even after including
import QtQuick 2.2
import QtQuick.Dialogs 1.1

Is there anything else i need to include?

Thanks in advance

Hi , did you see the example code at http://qt-project.org/doc/qt-5/qml-qtquick-dialogs-messagedialog.html#details ?
What did you try and why doesn't it work for you? The example looks fairly easy to implement I guess.

You just need to modify the code a little if you want to open it from a JS function, do it like
@
import QtQuick 2.2
import QtQuick.Dialogs 1.1

MessageDialog {
id: messageDialog
title: "May I have your attention please"
text: "It's so cool that you are using Qt Quick."
onAccepted: {
// whatever you wanna do
}
}

// in your JS function
messageDialog.open()
@

if you want you can of course create the MessageDialog dynamically, but this is the easy way :)
If you need to create it dynamically you can use a Loader or Component in QML.

Thank you.

Even though after including
import QtQuick 2.2
import QtQuick.Dialogs 1.1

For MessageDialog it says Unknown component. Do i need to add any library reference for my QtQuick 2 project .pro file?

Hi, I just tested it myself, works like it should be with Qt 5.2.1, you don't need to add any special libraries or modules in the project file. My test code:
@
import QtQuick 2.2
import QtQuick.Dialogs 1.1

Rectangle {
width: 300
height: 300

Component.onCompleted: messageDialog.open()

MessageDialog {
    id: messageDialog
    title: "May I have your attention please"
    text: "It's so cool that you are using Qt Quick."
}

}

that is all.. be aware that QtQuick.Dialogs is a dynamic QML plugin, so if you deploy your app and don't run that code from Qt Creator you have to deploy the QtQuick.Dialogs plugin with your app, obviously. :)
