95
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
101 · Unlimited undo/redo.
102
103 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
107 · Rectangular selections.
108
109 Rectangular text zones can be selected, copied, deleted, shifted
110 with the mouse or with the keyboard.
111
112 · Selection right/left char and tab shift.
113
114 Text selections can be shifted left/right of one or more chars or
115 a tabs.
116
117 · Normal and 'inline' selection paste.
118
119 The 'normal' paste is the normal text paste you know :
120
121 Paste Buffer:
122 line x
123
124 line y
125
126 Text Buffer:
127 line 1
128
129 line2
130
131 Normal paste at line 1:
132 line x
133
134 line y
135
136 line 1
137
138 line 2
139
140 The 'inline' paste work as this:
141 Inline paste at line 1:
142 line x line 1
143
144 line y line 2
145
146 · Parentheses matching.
147
148 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
157 · Autoindenting.
158
159 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
163 · Control codes insertion.
164
165 You can directly insert a non printable control character in the
166 text.
167
168 · Commands are managed via virtual events.
169
170 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
176 Example:
177 $w->eventAdd('Tk::Text::SuperText','<<SelectAll>>','<Control-a>');
178
179 To set default events bindigs use this methos: $w->bindDefault;
180
181 · Default key bindings are redefined (not really a feature :).
182
183 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).
