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).
When focus is initially grabbed and there is no focus column, when selecting
the first column for focus, further explicitly focus into the first cell
using gtk_cell_area_focus().
the edge.
When focusing left/right or up/down inside GtkCellArea, now we save what
was the last focused cell and if we hit the side (or top or bottom) of
the view we then restore focus to the last focused cell.
This function did alot of nothing, gtk_cell_area_focus() simply returns whether
the focus stays in the area (column) or not, seems not to cause regressions to
just call it directly instead.
Added a few apis,
- GtkCellAreaContext get_preferred_height_for_width &
width for height apis and vfuncs, this lets the icon view
request the collective (and aligned) height for width for
a said row.
- gtk_cell_area_copy_context() this creates a duplicate of
an already created and requested context, this way the icon
view uses a global context to request the widths of all rows
and then makes a copy with all the stored alignments and
uses a separate copy to calculate the height and alignments
of each row separately.
Instead this is now enforced in gtk_tree_view_get_cell_area_height().
There are rows for which a height in between 0 and expander_size is
allowed, for example separator rows.
This argument allows the caller to specify that only an editable
cell should start editing but an activatable cell should not toggle
it's state, this is important for public apis like
gtk_tree_view_set_cursor_on_cell() which are only intended to
programatically bring attention to the editing of a specific
row or cell but not actually change any data.
GtkTreeView & CellAreaScaffold updated for the last minute api change.
No longer need to detect if we're currently resetting the context since
the context properly now avoids re-triggering the reset by properly
avoiding to notify properties that dont change as a result of the reset.
This allows us to reduce code allocation code paths in subclasses, as
a result GtkCellArea implements the ->render() vfunc and the subclass
only decides the cell area and background area distributions in a single
code path.
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.
This allows us to add a check before executing
->get_preferred_height_for_width() to ensure we always
request for at least the minimum required size (and lets
us remove the warning in gtkcontainer.c telling implementors
to do this check manually from thier container implementations).
This fix is incorrect, treeviews dont rely on the expander size for drawing
separator rows (added XXX comment in line), need to fix this somewhere else
Scanner doesn't detect this case correctly because it's a typedef;
work around it here by explicitly specifying that it's caller
allocates. See bug 636393 for the scanner issue.
Commit 39f5740763 bumped the
autoconf version to 2.64 with no explicit rationale. It looks
to me like a copy-and-paste error. Reverting back to 2.62 (the
previous version). 2.63 at least (RHEL6) works here.
