/*
The FormWindow is the widget which is used as editor for forms. It
handles inserting, deleting, moving, resizing, etc. of widgets.
Normally multiple formwindows are used at the same time in the
Designer. So each formwindow has its own undo/redo buffer, etc.
Also the formwindow has some signals to inform e.g. about selection
changes which is interesting for the PropertyEditor.
For handling the events of the child widgets (moving, etc.) the
handleMousePress(), etc. functions are called from the application
event filter which is implemented in MainWindow::eventFilter().
