详细描述

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.

特性文档编制

[default] data : list < 对象 >

This default property holds the list of all objects declared as children of the dialog.

flags : Qt::WindowFlags

This property holds the window flags of the dialog. The default value is Qt.Dialog .

modality : Qt::WindowModality

This property holds the modality of the dialog. The default value is Qt.WindowModal .

Available values:

常量	描述
`Qt.NonModal`	The dialog is not modal and does not block input to other windows.
`Qt.WindowModal`	The dialog is modal to a single window hierarchy and blocks input to its parent window, all grandparent windows, and all siblings of its parent and grandparent windows.
`Qt.ApplicationModal`	The dialog is modal to the application and blocks input to all windows.

parentWindow : Window

This property holds the parent window of the dialog.

Unless explicitly set, the window is automatically resolved by iterating the QML parent objects until a Window 或 Item that has a window is found.

result : int

This property holds the result code.

Standard result codes:

常量	值
`Dialog.Accepted`
`Dialog.Rejected`

注意： MessageDialog sets the result to the value of the clicked standard button instead of using the standard result codes.

title : string

This property holds the title of the dialog.

visible : bool

This property holds the visibility of the dialog. The default value is false .
