    \class QDesignerFormWindowManagerInterface

    \brief The QDesignerFormWindowManagerInterface class allows you to
    manipulate the collection of form windows in Qt Designer, and
    control Qt Designer's form editing actions.

    \inmodule QtDesigner

    QDesignerFormWindowManagerInterface is not intended to be
    instantiated directly. \QD uses the form window manager to
    control the various form windows in its workspace. You can
    retrieve an interface to \QD's form window manager using
    the QDesignerFormEditorInterface::formWindowManager()
    function. For example:

    \snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindowmanager.cpp 0

    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.
    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 \QD's workspace.

    In addition, QDesignerFormWindowManagerInterface contains a
    collection of functions that enables you to intervene and control
    \QD'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.
