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 () 或 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.
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
