@ -2121,6 +2121,14 @@ The following is a list of the components and the properties they support.
Example: ``progress_hl_*.png``.
If the value is equal to ``bar_style`` then no styled boxes
will be shown.
@item highlight_overlay
@tab If this option is set to ``true`` then the highlight box
side slices (every slice except the center slice) will overlay the
frame box side slices. And the center slice of the highlight box
can move all the way (from top to bottom), being drawn on the center
slice of the frame box. That way we can make a progress bar with
round-shaped edges so there won't be a free space from the highlight to
the frame in top and bottom scrollbar positions. Default is ``false``.
@item font
@tab The font to use for progress bar.
@item text
