For example: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 2 - - When implementing a custom widget plugin, a pointer to \QD's - current QDesignerFormEditorInterface object (\c formEditor in the - example above) is provided by the - QDesignerCustomWidgetInterface::initialize() function's parameter. - - The member sheet (and any other extension), can be retrieved by - querying \QD's extension manager using the qt_extension() - function. When you want to release the extension, you only need to - delete the pointer. - - All widgets have a default member sheet used in \QD's signals and - slots editing mode with the widget's member functions. But - QDesignerMemberSheetExtension also provides an interface for - creating custom member sheet extensions. - - \warning \QD uses the QDesignerMemberSheetExtension to facilitate - the signal and slot editing mode. Whenever a connection between - two widgets is requested, \QD will query for the widgets' member - sheet extensions. If a widget has an implemented member sheet - extension, this extension will override the default member sheet. - - To create a member sheet extension, your extension class must - inherit from both QObject and QDesignerMemberSheetExtension. Then, - since we are implementing an interface, we must ensure that it's - made known to the meta object system using the Q_INTERFACES() - macro: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 3 - - This enables \QD to use qobject_cast() to query for - supported interfaces using nothing but a QObject pointer. - - In \QD the extensions are not created until they are - required. For that reason, when implementing a member sheet - extension, you must also create a QExtensionFactory, i.e a class - that is able to make an instance of your extension, and register - it using \QD's \l {QExtensionManager}{extension manager}. - - When a widget's member sheet extension is required, \QD's \l - {QExtensionManager}{extension manager} will run through all its - registered factories calling QExtensionFactory::createExtension() - for each until the first one that is able to create a member sheet - extension for that widget, is found. This factory will then make - an instance of the extension. If no such factory is found, \QD - will use the default member sheet. - - There are four available types of extensions in \QD: - QDesignerContainerExtension, QDesignerMemberSheetExtension, - QDesignerPropertySheetExtension and - QDesignerTaskMenuExtension. \QD's behavior is the same whether the - requested extension is associated with a multi page container, a - member sheet, a property sheet or a task menu. - - The QExtensionFactory class provides a standard extension - factory, and can also be used as an interface for custom - extension factories. You can either create a new - QExtensionFactory and reimplement the - QExtensionFactory::createExtension() function. For example: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 4 - - Or you can use an existing factory, expanding the - QExtensionFactory::createExtension() function to make the factory - able to create a member sheet extension as well.

For - example: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 15 - - Note that if you change the value of a property using the - QDesignerPropertySheetExtension::setProperty() function, the undo - stack is not updated. To ensure that a property's value can be - reverted using the undo stack, you must use the - QDesignerFormWindowCursorInterface::setProperty() function, or its - buddy \l - {QDesignerFormWindowCursorInterface::setWidgetProperty()}{setWidgetProperty()}, - instead. - - When implementing a custom widget plugin, a pointer to \QD's - current QDesignerFormEditorInterface object (\c formEditor in the - example above) is provided by the - QDesignerCustomWidgetInterface::initialize() function's parameter. - - The property sheet, or any other extension, can be retrieved by - querying \QD's extension manager using the qt_extension() - function. When you want to release the extension, you only need to - delete the pointer. - - All widgets have a default property sheet which populates \QD's - property editor with the widget's properties (i.e the ones defined - with the Q_PROPERTY() macro). But QDesignerPropertySheetExtension - also provides an interface for creating custom property sheet - extensions. - - \warning \QD uses the QDesignerPropertySheetExtension to feed its - property editor. Whenever a widget is selected in its workspace, - \QD will query for the widget's property sheet extension. If the - selected widget has an implemented property sheet extension, this - extension will override the default property sheet. - - To create a property sheet extension, your extension class must - inherit from both QObject and - QDesignerPropertySheetExtension. Then, since we are implementing - an interface, we must ensure that it's made known to the meta - object system using the Q_INTERFACES() macro: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 16 - - This enables \QD to use qobject_cast() to query for supported - interfaces using nothing but a QObject pointer. - - In \QD the extensions are not created until they are - required. For that reason, when implementing a property sheet - extension, you must also create a QExtensionFactory, i.e a class - that is able to make an instance of your extension, and register - it using \QD's \l {QExtensionManager}{extension manager}. - - When a property sheet extension is required, \QD's \l - {QExtensionManager}{extension manager} will run through all its - registered factories calling QExtensionFactory::createExtension() - for each until the first one that is able to create a property - sheet extension for the selected widget, is found. This factory - will then make an instance of the extension. If no such factory - can be found, \QD will use the default property sheet. - - There are four available types of extensions in \QD: - QDesignerContainerExtension, QDesignerMemberSheetExtension, - QDesignerPropertySheetExtension and QDesignerTaskMenuExtension. Qt - Designer's behavior is the same whether the requested extension is - associated with a multi page container, a member sheet, a property - sheet or a task menu. - - The QExtensionFactory class provides a standard extension factory, - and can also be used as an interface for custom extension - factories. You can either create a new QExtensionFactory and - reimplement the QExtensionFactory::createExtension() function. For - example: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 17 - - Or you can use an existing factory, expanding the - QExtensionFactory::createExtension() function to make the factory - able to create a property sheet extension extension as well. For - example: - - \snippet doc/src/snippets/code/doc_src_qtdesigner.qdoc 18 - - For a complete example using an extension class, see the \l - {designer/taskmenuextension}{Task Menu Extension example}.
