| 34 | \class QDesignerWidgetBoxInterface |
| 35 | |
| 36 | \brief The QDesignerWidgetBoxInterface class allows you to control |
| 37 | the contents of Qt Designer's widget box. |
| 38 | |
| 39 | \inmodule QtDesigner |
| 40 | |
| 41 | QDesignerWidgetBoxInterface contains a collection of functions |
| 42 | that is typically used to manipulate the contents of \QD's widget |
| 43 | box. |
| 44 | |
| 45 | \QD uses an XML file to populate its widget box. The name of that |
| 46 | file is one of the widget box's properties, and you can retrieve |
| 47 | it using the fileName() function. |
| 48 | |
| 49 | QDesignerWidgetBoxInterface also provides the save() function that |
| 50 | saves the contents of the widget box in the file specified by the |
| 51 | widget box's file name property. If you have made changes to the |
| 52 | widget box, for example by dropping a widget into the widget box, |
| 53 | without calling the save() function, the original content can be |
| 54 | restored by a simple invocation of the load() function: |
| 55 | |
| 56 | \snippet lib/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 0 |
| 57 | |
| 58 | The QDesignerWidgetBoxInterface class is not intended to be |
| 59 | instantiated directly. You can retrieve an interface to Qt |
| 60 | Designer's widget box using the |
| 61 | QDesignerFormEditorInterface::widgetBox() function. A pointer to |
| 62 | \QD's current QDesignerFormEditorInterface object (\c formEditor |
| 63 | in the example above) is provided by the |
| 64 | QDesignerCustomWidgetInterface::initialize() function's |
| 65 | parameter. When implementing a custom widget plugin, you must |
| 66 | subclass the QDesignerCustomWidgetInterface to expose your plugin |
| 67 | to \QD. |
| 68 | |
| 69 | If you want to save your changes, and at the same time preserve |
| 70 | the original contents, you can use the save() function combined |
| 71 | with the setFileName() function to save your changes into another |
| 72 | file. Remember to store the name of the original file first: |
| 73 | |
| 74 | \snippet lib/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 1 |
| 75 | |
| 76 | Then you can restore the original contents of the widget box by |
| 77 | resetting the file name to the original file and calling load(): |
| 78 | |
| 79 | \snippet lib/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 2 |
| 80 | |
| 81 | In a similar way, you can later use your customized XML file: |
| 82 | |
| 83 | \snippet lib/tools_designer_src_lib_sdk_abstractwidgetbox.cpp 3 |
| 84 | |
