From eda80390d5afc4346d2e64a256762df7df30bb17 Mon Sep 17 00:00:00 2001 From: Jonathan Gordon Date: Sun, 15 Aug 2010 14:13:36 +0000 Subject: A bunch of new features for the bar type tags (%pb, %pv, %bl, etc): * the bar orientation (horiz/vert) is now chosen based on the width and heigt values (or can be forced). * the fill direction can now be inverted (fill right to left, or top to bottom is considered inverted) * It can now draw a slider type bar instead of a fill type (or indeed a slider with a fill type) To configure the new bar, any (or all) of the following params can be used after the bmp filename (order makes no difference either): invert - cause the bar to fill in the inverted direction vertical - draw a vertical bar (not needed if the height > width) horizontal - draw a horizontal bar (this is obviously the default) nofill - dont draw the filling bar (this still draws the outline, obviously pointless without the slider param) slider - draw an image for the slider. The next param MUST be the label of the image to draw. No option to use a subimage here, so the whole image needs to be the image you want on the slider. example: %pb(0,0,-,-,-,nofill, slider, slider_image, invert) - draw a boring horizontal progressbar which doesnt fill and only draws the image "slider_image" which moves right to left. the slider type might need some tweaking. let us know how it goes git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27821 a1c6a512-1295-4272-9138-f99709370657 --- apps/gui/skin_engine/skin_display.c | 77 ++++++++++++++++++++++++++++++++---- apps/gui/skin_engine/skin_parser.c | 37 +++++++++++++++++ apps/gui/skin_engine/wps_internals.h | 5 +++ 3 files changed, 111 insertions(+), 8 deletions(-) (limited to 'apps/gui/skin_engine') diff --git a/apps/gui/skin_engine/skin_display.c b/apps/gui/skin_engine/skin_display.c index 53b568ad53..8e08343d82 100644 --- a/apps/gui/skin_engine/skin_display.c +++ b/apps/gui/skin_engine/skin_display.c @@ -129,7 +129,10 @@ void draw_progressbar(struct gui_wps *gwps, int line, struct progressbar *pb) struct wps_state *state = gwps->state;
