set-selection

Arguments: stream start &optional (end start)

Sets the selected text in stream, which must be a text-edit-window, text-edit-pane, a text control (such as an editable-text or multi-line-editable-text), to be the characters indexed by start (inclusive) and end (exclusive). If start equals end, the cursor is placed before the character at start, but no text is selected. Indexing is zero-based so the first character is index 0. Two invisible characters typically appear at the end of a line.

This function also works on editor buffers (instances of lisp-edit-pane). For a simple test of this function, open an editor window (click View | New Editor if necessary). Click on Tools | Get Component and click on the editor pane. The object will be returned in the Debug Window. In the Debug Window, evaluate

(setq lp *)

Now, in the editor pane, enter

0123456789
0123456789

(with no spaces).

(set-selection lp 0 2) selects 01 in the first line.

(set-selection lp 0 10) selects all characters in the first line.

(set-selection lp 0 13) selects all the first line and 0 in the second

line. (the 11th and 12th characters are the carriage-return and linefeed).
