The Dialog type provides common QML API for native platform dialogs.
To show a native dialog, construct an instance of one of the concrete Dialog implementations, set the desired properties, and call open() . Dialog emits accepted() or rejected() when the user is done with the dialog.
注意: Types in Qt.labs modules are not guaranteed to remain compatible in future versions.

This default property holds the list of all objects declared as children of the dialog.
This property holds the window flags of the dialog. The default value is

.
Available values:

The dialog is modal to the application and blocks input to all windows. |
