DESCRIPTION

Tk::Text::SuperText implements many new features over the standard Tk::Text widget while supporting all it's standard features.Its used simply as the Tk::Text widget. New Features:

• Unlimited undo/redo.

  So you can undo and redo whatever you deleted/inserted whenever you want. To reset the undo and redo buffers call this method: $w->resetUndo;

• Rectangular selections.

  Rectangular text zones can be selected,copied,deleted,shifted with the mouse or with the keyboard.

• Selection right/left char and tab shift.

  Text selections can be shifted left/right of one or more chars or a tabs.

• Normal and 'inline' selection paste.

  The 'normal' paste is the normal text paste you know :

  Paste Buffer:

  line x

  line y

  Text Buffer:

  line 1

  line2

  Normal paste at line 1:

  line x

  line y

  line 1

  line 2

  The 'inline' paste work as this:

  Inline paste at line 1:

  line x line 1

  line y line 2

• Parentheses matching.

  To help you inspect nested parentheses,brackets and other characters,SuperText has both an automatic parenthesis matching mode,and a find matching command. Automatic parenthesis matching is activated when you type or when you move the insertion cursor after a parenthesis.It momentarily highlightsthe matching character if that character is visible in the window.To find a matching character anywhere in the file,position the cursor after the it,and call the find matching command.

• Autoindenting.

  When you press the Return or Enter key,spaces and tabs are inserted to line up the insert point under the start of the previous line.

• Control codes insertion.

  You can directly insert a non printable control character in the text.

• Commands are managed via virtual events.

  Every SuperText command is binded to a virtual event,so to call it or to bind it to a key sequence use the Tk::event functions. I used this format for key bind so there's no direct key-to-command bind,and this give me more flexibility;however you can use normal binds.

  Example: $w->eventAdd('Tk::Text::SuperText','<<SelectAll>>','<Control-a>');

  To set default events bindigs use this methos: $w->bindDefault;

• Key bindings are sometimes redefined (not really a feature :).
