Remove the --sync option and remove the possibility of backend-specific
commandline options altogether. --sync is being replaced by
a GDK_SYNCHRONIZE environment variable.
Commandline arguments should go away altogether, but this one
goes first, since we then don't need to worry about
_gdk_windowing_substitute_screen_number anymore.
This commit does a number of things:
- remove some dead wchar configury from configure.ac and gdkconfig.h
- repurpose gdkconfig.h as header that contains GDK_WINDOWING_foo
macros for each included backend, include it in gdk.h and install
it in $includedir instead of below $libdir
- drop the backend from the library names
- build libgdk-3.0.la as a convenience lib and include it in libgtk-3.0.la
It does not yet enable building multiple backends at the same time.
The old functions to get core pointer and devices list are gone as
well. This slice is entirely replaced internally by multidevice
handling and may just go.
Added gtk_cell_area_context_get_preferred_height_for_width and
width_for_height & gtk_cell_area_copy_context() to gtk.symbols
and gtk3-sections.txt (also finished up documenting those apis).
Move the guide into the 2-to-3 guide, since it is something
you have to do when porting from 2 to 3. Also add an example
for handling of temporary state changes and some more text
about color handling.
gtk_cell_area_foreach_alloc() itterates over an allocated list of cells
and calls a callback with the cell's allocation until the callback returns
TRUE.
- Removed vfunc get_cell_allocation() and implemented
gtk_cell_area_get_cell_allocation() using foreach_alloc()
- Added gtk_cell_area_get_cell_at_position() using foreach_alloc()
- Removed GtkCellAreaBox ->event() implementation and implemented
mouse "click" cell activation in GtkCellArea class directly using
gtk_cell_area_get_cell_at_position().
