2000-03-07 Christopher James Lahey <clahey@helixcode.com>
* widgets/e-text/e-text.c, widgets/e-text/e-text.h: Added a
"break_characters" argument. It lets you define a set of
characters which should cause optional linebreaks to occur. Made
setting the "clip_height" argument to -1 mean no height clipping.
Moved calling the "resize" signal into an idle handler to avoid
reentering the canvas update loop. Made EText recalc bounds if
the affine has changed. Fixed up tooltip_count (this counts the
number of ENTER and LEAVE events.)
* widgets/e-text/e-text-test.c: Got rid of a few warnings.
* widgets/e-minicard/e-minicard-label.h: Reindent a few lines.
* widgets/e-minicard/e-minicard.c,
widgets/e-minicard/e-minicard-label.c: Switch from using "x" and
"y" to set the children's position to using
e_canvas_item_move_absolute.
