We use the QT Toolkit for GUI- and other programming. The <SPAN  CLASS="textit">QT-Assistant</SPAN>
is an important tool for getting help. Almost everything can be looked
up there.

<P>
GUIs can be either be hardcoded (see <TT>fterfirsta`a=95 _ `a=58 : 
      `a&gt;64
        `a&lt;91 aaa

                            c@amelhyph<269>>rranger.cpp</TT> for an example)
or can be created using <SPAN  CLASS="textit">QT-Designer</SPAN> (see the dialogs under
<TT>fterfirstw`w=95 _ `w=58 :

                            c@amelhyph<269>>idgets/function_dialogs/</TT> for mostly cleanly-written examples).
Don't forget to add your <TT>fterfirstc`c=95 _ `c=58 :
