rockbox/firmware/export/lcd-remote.h, branch master My Rockbox tree put_line/scrolling: Make the scroll engine inform custom scrollers about start/stop of scrolling. 2014-01-12T00:34:06+00:00 Thomas Martitz kugel@rockbox.org 2014-01-12T00:30:26+00:00 488a1b983e1c2fac14de25aa781caf12628e53c8 With the new lcd_putsxy_scroll_func() code can register custom scroll functions (put_line() makes use of that). In order for the custom scroller to be able to properly manage its userdata pointer (set via struct scrollinfo::userdata) the scroll engine must inform the scroller about start and stop of scrolling. To inform about start the lcd_scroll_* functions now return true when the line will scroll. To inform about stop the scroll engine calls into the scroller one last time, with the text set to NULL. put_line() can use this to release the userdata registered per scrolling line so that it can be recycled. This fixes that some scrolling lines became glitchy after some time because the userdata was recycled too early. Change-Id: Iff0a6ce2a4f9ae2bada1b8e62f4f5950224942a9 
With the new lcd_putsxy_scroll_func() code can register custom scroll functions
(put_line() makes use of that). In order for the custom scroller to be able
to properly manage its userdata pointer (set via struct scrollinfo::userdata)
the scroll engine must inform the scroller about start and stop of scrolling.

To inform about start the lcd_scroll_* functions now return true when
the line will scroll. To inform about stop the scroll engine calls into the
scroller one last time, with the text set to NULL.

put_line() can use this to release the userdata registered per scrolling line
so that it can be recycled.

This fixes that some scrolling lines became glitchy after some time because
the userdata was recycled too early.

lcd-common/scroll_engine: Remove unused functions lcd_puts_style_xyoffset() and lcd_puts_scroll_style_xyoffset(). 2014-01-07T13:13:48+00:00 Thomas Martitz kugel@rockbox.org 2013-04-14T16:15:09+00:00 9a4686b563ac9e27615e1032792bd9878bb291f7 With this functions removed there is no exported function in firmware left that draws line decorations. Also no function supports specifying an y-offset anymore (was used for pixel accurate positioning of otherwise strictly line-based API calls). Both should be handled in apps/ now.
