2003-02-20 Sven Neumann <sven@gimp.org> * libgimpbase/gimputils.c (gimp_utf8_strtrim): trim the string only if necessary. * app/text/gimptext.c: changed the default text to NULL. * app/widgets/gimptexteditor.[ch]: replaced Cancel and OK buttons with a single Close button and removed the callback. * app/widgets/gimppropwidgets.c: gtk_text_buffer_set_text() doesn't like NULL pointers, pass it an empty string instead. * app/tools/gimptexttool.c: create a new text layer as soon as the user starts editing.

/**

* gimp_utf8_strtrim:

* @str: an UTF-8 encoded string (or %NULL)

* @max_chars: the maximum number of characters before the string get

* trimmed
|

*
|
|
* Creates a (possibly trimmed) copy of @str. The string is cut if it
