\class QDesignerFormWindowCursorInterface
\brief The QDesignerFormWindowCursorInterface class allows you to
query and modify a form window's widget selection, and in addition
modify the properties of all the form's widgets.
\inmodule QtDesigner
QDesignerFormWindowCursorInterface is a convenience class that
provides an interface to the associated form window's text cursor;
it provides a collection of functions that enables you to query a
given form window's selection and change the selection's focus
according to defined modes (MoveMode) and movements
(MoveOperation). You can also use the interface to query the
form's widgets and change their properties.
The interface is not intended to be instantiated directly, but to
provide access to the selections and widgets of \QD's current form
windows. QDesignerFormWindowInterface always provides an
associated cursor interface. The form window for a given widget
can be retrieved using the static
QDesignerFormWindowInterface::findFormWindow() functions. For
example:
\snippet doc/src/snippets/code/tools_designer_src_lib_sdk_abstractformwindowcursor.cpp 0
You can retrieve any of \QD's current form windows through
\QD's \l {QDesignerFormWindowManagerInterface}{form window
manager}.
Once you have a form window's cursor interface, you can check if
the form window has a selection at all using the hasSelection()
function. You can query the form window for its total
widgetCount() and selectedWidgetCount(). You can retrieve the
currently selected widget (or widgets) using the current() or
selectedWidget() functions.
You can retrieve any of the form window's widgets using the
widget() function, and check if a widget is selected using the
isWidgetSelected() function. You can use the setProperty()
function to set the selected widget's properties, and the
setWidgetProperty() or resetWidgetProperty() functions to modify
the properties of any given widget.
Finally, you can change the selection by changing the text
cursor's position() using the setPosition() and movePosition()
functions.
