plasma-framework/widgets/lineedit.h
Aaron J. Seigo 5f8c6be988 make Applet (and lineedit) usable with qgraphics_item cast. we probably want to do this with all of our QGI subclasses.
i introduced a new enum in the Plasma namespace, ItemType, so we can keep track of these id's centrally.
however, the right click mechanism is rather broken in its implementation; we need a way to offer a centralized menu on appets no metter where they are clicked.
