We use the QT Toolkit for GUI- and other programming. The QT-Assistant
is an important tool for getting help. Almost everything can be looked
up there.
GUIs can be either be hardcoded (see fterfirsta`a=95 _ `a=58 : 
      `a>64
        `a<91 aaa
                            <`<=95 _ `<=58 : 
      `<>64
        `<<91 <<<
                            c@amelhyph<269>>rranger.cpp for an example)
or can be created using QT-Designer (see the dialogs under
fterfirstw`w=95 _ `w=58 : 
      `w>64
        `w<91 www
                            <`<=95 _ `<=58 : 
      `<>64
        `<<91 <<<
                            c@amelhyph<269>>idgets/function_dialogs/ for mostly cleanly-written examples).
Don't forget to add your fterfirstc`c=95 _ `c=58 : 
      `c>64
        `c<91 ccc
                            <`<=95 _ `<=58 :

      `<>64
        `<<91 <<<
                            c@amelhyph<269>> and fterfirstu`u=95 _ `u=58 : 
      `u>64
        `u<91 uuu
                            <`<=95 _ `<=58 : 
      `<>64
        `<<91 <<<
                            c@amelhyph<269>>i files to the
corresponding sections in the fterfirstC`C=95 _ `C=58 : 
      `C>64
        `C<91 CCC
                            <`<=95 _ `<=58 :

Additionally, MusE offers some custom widgets, like menu title items etc.
Following, there will be a small, unordered list about custom widgets:
