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.

visible : bool
