2014-01-12put_line/scrolling: Make the scroll engine inform custom scrollers about ↵Thomas Martitz
start/stop of scrolling. 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
2014-01-11scroll engine: Factor out renderer function so it can be called by lcd code.Thomas Martitz
This is used by lcd_puts_scroll_worker() to render the line immediately instead of waiting for the next scroll tick when only the text was updated. Previously lcd_puts_scroll_worker() did not render anything in this case which could lead to visible blinking. This fixes blinking scrolling lines with dynamic text in the skin engine.

2014-01-07lcd-common: Remove direct style (line decorations) from lcd-puts* functions.Thomas Martitz
This logic is moved into apps (put_line()) which can better handle line decorations with respect to scrolling, mulitline and other complications. Firmware doesn't need this. The remaining drawing function know only one style, that is foreground on background/backdrop (changing drawmode is still supported). Change-Id: I707060edc388a7d723a7d09b0cf5cbda6ec56708

2013-12-14scroll_engine: Major rework to support pixel-based scrolling and scroll ↵Thomas Martitz
callbacks. Much of the scrolling work is moved from lcd-bitmap-common to lcd-scroll.c, a small scroll callback routine remains. This callback can potentially be overridden by more extensive scrollers. The callback also gets fed with pixel-based scrolling information, which finally removes the strict line-based nature of the scroll engine. Along with this is the change from scroll_stop_viewport_line() to scroll_stop_viewport_rect() which works on a pixel-based rectangle instead of lines. The ultimate goal is to move most of the scroll work to apps, which can much better decide which line decorations to apply etc. This work is laying the ground work.

2010-10-06Pixel-accurate (vertical) list scrolling for touchscreen targets.Thomas Martitz
Looks much smoother now as you don't scroll by whole lines anymore. Add some functions lcd driver to enable the line based scrolling engine to draw the lines with a pixel-based y-offset. This should also allow for a sensible kinetic scrolling mechanism (still a todo). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28214 a1c6a512-1295-4272-9138-f99709370657
2010-03-03FS#10756 - Free unused init codeThomas Martitz
Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back. Only implemented for PP and as3525 so far. More targets could be added, as well as more functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25013 a1c6a512-1295-4272-9138-f99709370657

2010-02-08revert r24478 and make the backdrop behaviour the same as it used to be (so ↵Jonathan Gordon
when in the wps the sbs' backdrop will be fully disabled). Also changes the API back to having to manually set the current backdrop. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24565 a1c6a512-1295-4272-9138-f99709370657
2010-02-03fix a bug where the backdrop from the sbs is displayed on scrolling lines in ↵Jonathan Gordon
the wps when the %wd tag is not used. I'm not crazy about this commit and maybe a better solution would be to outright disable the sbs backdrop when in any skinned screen. This then means backdrops go back to needing special handling (i.e they arnt "free") git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24478 a1c6a512-1295-4272-9138-f99709370657

2007-09-27FS#7808 by Tom Ross, Ken Fazzone and me, with help from Antoine Cellerier.Nicolas Pennequin
Add two new line selector types: solid colour and gradient. Solid colour only uses the primary colour setting. The secondary colour setting is used for the gradient. Text colour for the selected item is also changeable. These new settings are a bit controversial so they may be removed later. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14868 a1c6a512-1295-4272-9138-f99709370657
