|
---|
49 | \brief The QDesignerWidgetBoxInterface class allows you to control
|
---|
50 | the contents of Qt Designer's widget box.
|
---|
51 |
|
---|
52 | \inmodule QtDesigner
|
---|
53 |
|
---|
54 | QDesignerWidgetBoxInterface contains a collection of functions
|
---|
55 | that is typically used to manipulate the contents of \QD's widget
|
---|
56 | box.
|
---|
57 |
|
---|
58 | \QD uses an XML file to populate its widget box. The name of that
|
---|
59 | file is one of the widget box's properties, and you can retrieve
|
---|
60 | it using the fileName() function.
|
---|
61 |
|
---|
62 | QDesignerWidgetBoxInterface also provides the save() function that
|
---|
63 | saves the contents of the widget box in the file specified by the
|
---|
64 | widget box's file name property. If you have made changes to the
|
---|
65 | widget box, for example by dropping a widget into the widget box,
|
---|
66 | without calling the save() function, the original content can be
|
---|
67 | restored by a simple invocation of the load() function:
|
---|
68 |
|
---|
69 | \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 0
|
---|
70 |
|
---|
71 | The QDesignerWidgetBoxInterface class is not intended to be
|
---|
72 | instantiated directly. You can retrieve an interface to Qt
|
---|
73 | Designer's widget box using the
|
---|
74 | QDesignerFormEditorInterface::widgetBox() function. A pointer to
|
---|
75 | \QD's current QDesignerFormEditorInterface object (\c formEditor
|
---|
76 | in the example above) is provided by the
|
---|
77 | QDesignerCustomWidgetInterface::initialize() function's
|
---|
78 | parameter. When implementing a custom widget plugin, you must
|
---|
79 | subclass the QDesignerCustomWidgetInterface to expose your plugin
|
---|
80 | to \QD.
|
---|
81 |
|
---|
82 | If you want to save your changes, and at the same time preserve
|
---|
83 | the original contents, you can use the save() function combined
|
---|
84 | with the setFileName() function to save your changes into another
|
---|
85 | file. Remember to store the name of the original file first:
|
---|
86 |
|
---|
87 | \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 1
|
---|
88 |
|
---|
89 | Then you can restore the original contents of the widget box by
|
---|
90 | resetting the file name to the original file and calling load():
|
---|
91 |
|
---|
92 | \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 2
|
---|
93 |
|
---|
94 | In a similar way, you can later use your customized XML file:
|
---|
95 |
|
---|
96 | \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 3
