Dialog

This property holds the button pressed by the user. Its value is one of the flags set for the standardButtons property.

The QML object which implements the dialog contents. Should be an Item.

For example the following dialog will show custom content and no buttons:

import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Dialogs 1.2

Dialog {
    visible: true
    title: "Blue sky dialog"

    contentItem: Rectangle {
        color: "lightskyblue"
        implicitWidth: 400
        implicitHeight: 100
        Text {
            text: "Hello blue sky!"
            color: "navy"
            anchors.centerIn: parent
        }
    }
}

Whether the dialog should be shown modal with respect to the window containing the dialog's parent Item, modal with respect to the whole application, or non-modal.

By default it is Qt.WindowModal.

Modality does not mean that there are any blocking calls to wait for the dialog to be accepted or rejected: only that the user will be prevented from interacting with the parent window or the application windows until the dialog is dismissed.

Dialog has a row of buttons along the bottom, each of which has a ButtonRole that determines which signal will be emitted when the button is pressed. You can also find out which specific button was pressed after the fact via the clickedButton property. You can control which buttons are available by setting standardButtons to a bitwise-or combination of the following flags:

For example the following dialog will show a calendar with the ability to save or cancel a date:

import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Dialogs 1.2

Dialog {
    id: dateDialog
    visible: true
    title: "Choose a date"
    standardButtons: StandardButton.Save | StandardButton.Cancel

    onAccepted: console.log("Saving the date " +
        calendar.selectedDate.toLocaleDateString())

    Calendar {
        id: calendar
        onDoubleClicked: dateDialog.click(StandardButton.Save)
    }
}

The default is StandardButton.Ok.

The enum values are the same as in QMessageBox::StandardButtons.

The title of the dialog window.

This property holds whether the dialog is visible. By default this is false.

This signal is emitted when the user has pressed any button which has the AcceptRole: OK, Open, Save, Save All, Retry or Ignore.

The corresponding handler is onAccepted.

This signal is emitted when the user has pressed the Apply button.

The corresponding handler is onApply.

This signal is emitted when the user has pressed the Discard button.

The corresponding handler is onDiscard.

This signal is emitted when the user has pressed the Help button. Depending on platform, the dialog may not be automatically dismissed because the help that your application provides may need to be relevant to the text shown in this dialog in order to assist the user in making a decision. However on other platforms it's not possible to show a dialog and a help window at the same time. If you want to be sure that the dialog will close, you can set visible to false in your handler.

The corresponding handler is onHelp.

This signal is emitted when the user has pressed any button which has the NoRole: No or No to All.

The corresponding handler is onNo.

This signal is emitted when the user has dismissed the dialog, by closing the dialog window, by pressing a Cancel, Close or Abort button on the dialog, or by pressing the back button or the escape key.

The corresponding handler is onRejected.

This signal is emitted when the user has pressed any button which has the ResetRole: Reset or Restore Defaults.

The corresponding handler is onReset.
