97 Tk::Text::SuperText implements many new features over the standard
98 Tk::Text widget while supporting all it's standard features.Its used
99 simply as the Tk::Text widget. New Features:
100 · Unlimited undo/redo.
102 So you can undo and redo whatever you deleted/inserted whenever you
104 want. To reset the undo and redo buffers call this method:
105 $w->resetUndo;
106 · Rectangular selections.
108 Rectangular text zones can be selected, copied, deleted, shifted
110 with the mouse or with the keyboard.
111 · Selection right/left char and tab shift.
113 Text selections can be shifted left/right of one or more chars or
115 a tabs.
116 · Normal and 'inline' selection paste.
118 The 'normal' paste is the normal text paste you know :
120 Paste Buffer:
122 line x
123 line y
125 Text Buffer:
127 line 1
128 line2
130 Normal paste at line 1:
132 line x
133 line y
135 line 1
137 line 2
139 The 'inline' paste work as this:
141 Inline paste at line 1:
142 line x line 1
143 line y line 2
145 · Parentheses matching.
147 To help you inspect nested parentheses, brackets and other
149 characters, SuperText has both an automatic parenthesis matching
150 mode, and a find matching command. Automatic parenthesis matching
151 is activated when you type or when you move the insertion cursor
152 after a parenthesis. It momentarily highlightsthe matching
153 character if that character is visible in the window. To find a
154 matching character anywhere in the file, position the cursor after
155 the it, and call the find matching command.
156 · Autoindenting.
158 When you press the Return or Enter key, spaces and tabs are
160 inserted to line up the insert point under the start of the
161 previous line.
162 · Control codes insertion.
164 You can directly insert a non printable control character in the
166 text.
167 · Commands are managed via virtual events.
169 Every SuperText command is binded to a virtual event,so to call it
171 or to bind it to a key sequence use the Tk::event functions. I
172 used this format for key bind so there's no direct key-to-command
173 bind, and this give me more flexibility; however you can use normal
174 binds.
175 Example:
177 $w->eventAdd('Tk::Text::SuperText','<<SelectAll>>','<Control-a>');
178 To set default events bindigs use this methos: $w->bindDefault;
180 · Default key bindings are redefined (not really a feature :).
182 Every virtual event has an associated public method with the same
184 name of the event but with the firts char in lower case (eg:
185 <<MouseSelect>> event has a corresponding $super_text->mouseSelect
186 method).
