\param moudule Module which holds the params
\param view Unused today - may get style information in the future.
- This function builds a VBox, and puts it into a Gtk::Plug. This way
- the native window pointer can be pulled out and returned up to be
- stuck in a Gtk::Socket further up the call stack. In the Vbox there
- are several Hboxes, each one being a spin button to adjust a particular
- parameter. The names of the parameters and the labels are all
- stored in the arrays in the middle of the function. This makes
- the code very generic. This will probably have to change if someone
- wants to make this dialog look nicer.
+ Uses AutoGUI for creating the GUI.
