Detailed DescriptionThe QDesignerFormWindowManagerInterface class allows you to manipulate the collection of form windows in Qt Designer, and control Qt Designer's form editing actions. QDesignerFormWindowManagerInterface is not intended to be instantiated directly. Qt Designer uses the form window manager to control the various form windows in its workspace. You can retrieve an interface to Qt Designer's form window manager using the QDesignerFormEditorInterface::formWindowManager() function. For example: QDesignerFormWindowManagerInterface *manager = 0; QDesignerFormWindowInterface *formWindow = 0; manager = formEditor->formWindowManager(); formWindow = manager->formWindow(0); manager->setActiveFormWindow(formWindow); When implementing a custom widget plugin, a pointer to Qt Designer's current QDesignerFormEditorInterface object (formEditor in the example above) is provided by the QDesignerCustomWidgetInterface::initialize() function's parameter. You must subclass the QDesignerCustomWidgetInterface to expose your plugin to Qt Designer. The form window manager interface provides the createFormWindow() function that enables you to create a new form window which you can add to the collection of form windows that the manager maintains, using the addFormWindow() slot. It also provides the formWindowCount() function returning the number of form windows currently under the manager's control, the formWindow() function returning the form window associated with a given index, and the activeFormWindow() function returning the currently selected form window. The removeFormWindow() slot allows you to reduce the number of form windows the manager must maintain, and the setActiveFormWindow() slot allows you to change the form window focus in Qt Designer's workspace. In addition, QDesignerFormWindowManagerInterface contains a collection of functions that enables you to intervene and control Qt Designer's form editing actions. All these functions return the original action, making it possible to propagate the function further after intervention. Finally, the interface provides three signals which are emitted when a form window is added, when the currently selected form window changes, or when a form window is removed, respectively. All the signals carry the form window in question as their parameter. See also QDesignerFormEditorInterface and QDesignerFormWindowInterface. Member Type Documentation
