Set cursor position in a Text widget

Question

Is it possible to set the cursor position in a Tkinter Text widget? I\'m not finding anything terribly useful yet.

The best I\'ve been able to do is emit a <

Answer 1

This property is just for Text Widget, because for Entry Widget we could use:

entry_widget_name.icursor("position")

For Text Widget will be:

text_widget_name.mark_set("insert", "%d.%d" % (x,y))

where x = row position y = column position

(using integer numbers with dots like 1.0 or 3.0 for example)

Answer 2

If "text", "line", and "column" are your text object, the desired text line and desired column variables are, respectively:

text.mark_set("insert", "%d.%d" % (line + 1, column + 1))

If you would not like to care about the line number... well, you have to.

Answer 3

To set the cursor position, you can use the text_widget.mark_set method, with "insert" (or Tkinter.INSERT for a “constant”) first argument and, for the second argument, one of many forms, the most useful being:

• "%d,%d" % (line, column), where line is 1-based and column is 0-based
• "1.0+%d chars" % index, where index is 0-based just like a string/unicode index in Python

To get the index of a mark, you can use the text_widget.index method:

text_widget.index(Tkinter.INSERT)
