\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.
