Previously the expected behaviour for front ends using the correct
API for hotlist, global history, cookie manager, and ssl cert
viewer was that the front end would initialise the treeview module
on startup and finalise it on application exit.
However, this meant that the front ends had to include the core
treeview header, which they didn't otherwise need.
Since the tree module provided access to the new treeview utilities
through the old tree API, and was used by front ends with no changes
for the new treeview API, the tree layer refcounted initialisations
of treeview-based widgets, and only called the underlying treeview
init/fini functions when needed.
This change moves that refcounting into the treeview module. Now
the hotlist, global history, cookie manager, and ssl cert viewer
widgets call call treeview init/fini as part of their own
initialisation and finalisation. This means that front ends
using the correct APIs for treeview-based widgets don't need to
know anything about the underlying treeview, and the tree module
compatibility layer has had its treeview refcounting removed.
Finally, the treeview_init function took a font size parameter.
Now it does not and lit gets font size from config. We probably
want to add a new `treeview_font_size` option to nsoptions, and
have differnent defaults on different platforms. 12pt on RISC OS,
and 11pt elsewhere, most likely.
This changes the LOG macro to be varadic removing the need for all
callsites to have double bracketing and allows for future improvement
on how we use the logging macros.
The callsites were changed with coccinelle and the changes checked by
hand. Compile tested for several frontends but not all.
A formatting annotation has also been added which allows the compiler
to check the parameters and types passed to the logging.
The netsurf core is driven from numerous operation tables most of
which are now set through a common netsurf_register() interface. The
font and plotting interfaces are currently separate and unlike all the
other operation tables are modified for differing contexts.
This change moves the font operations alongside all the other
operations table and remove unnecessary interaction with the renderers
font internals. Further this also removes the need for css internals
to be visible in frontends.
Currently it can only open, display and launch entries in an existing hotlist file.
TODO:
- Generate defualt hotlist when file not found.
- Add hotlist saving.
- Allow adding to hotlist.
- Allow hotlist editing.
- Allow hotlist nodes to be moved by dragging.
- Allow hotlist visit data to be updated.
Now single callback for both redraw requests and drag reports.
Update treeview to use new textarea API.
Update Atari URL bar to use new textarea API. (Ignores drag reports, currently.)
Minor textarea fixes.
