Since parse() is a method of the Gdk.RGBA class, the GdkRGBA pointer
should be the first argument, and the string the second one, to allow a
more natural binding.

This is still very much a work in progress, but it renders and more or
less works. I will be fixing up the details in the very near future.
Important: this commit breaks ABI as it modifies the GtkTreeViewColumn
structure in gtktreeviewcolumn.h. This is a sealed structure that needs
to be moved to an internal header file, most likely gtktreeprivate.h.
Slight tweak for GtkTreeView, also non-editable cells must be able to receive
focus to get all keyboard navigation right. This will be further tweaked
to get focus siblings to work like focus cells did in GtkTreeView before
refactoring.
The allocated size, or (horizontally speaking) for-width size, can be
smaller than the sum of all minimum widths. For example when the user
is resizing tree view columns manually.
What this means is basically that a vertically oriented GtkCellAreaBox
will render cells properly even if the height is not constant for every
for of data in the said GtkCellAreaContext (i.e. the height was not allocated
by gtk_cell_area_context_allocate).
This is done completely on the fly and so is much more heavy duty
at render time (considerably slower but not visibly noticable in
lightweight views like GtkTreeMenu). Note that cell alignments
are not possible in an unallocated orientation, each row of data
individually receives only enough space to render the independant
row and no space is reserved for alignments if the size is not
a constant size across rows in the same context.
Since a cell renderer might use more space than the natural
size when recieving expand space it's impossible to know how
much space is actually used to render content.
Adding this virtual method to allow text renderers to implement
it, the base default method uses height-for-width apis and aligns
the cell assuming the renderer uses a fixed size.
This commit removes the similar code from gtkcellarea and
subclasses.
- gtk_cell_area_context_get_height_for_width()
- gtk_cell_area_context_get_width_for_height()
- gtk_cell_area_context_push_height_for_width()
- gtk_cell_area_context_push_width_for_height()
- gtk_cell_area_context_flush_height_for_width()
- gtk_cell_area_context_flush_width_for_height()
- Contextual size changed signal
All of these are not really important for the CellArea to operate
and not of any real consequential value to the user (the user can
accumulate the returned values from height-for-width requests
and do as they please with it).
This is so that treeviews can have some columns oriented vertically and
some horizontally, usually the column will only allocate the areas
width, having vertical columns without fixed row heights just means
it's slower to render.
Since Havoc's patches introducing the GtkWidget halign/valign
properties, fill should always be TRUE. If the widget should
not fill its allocated space then it should set the halign or
valign properties for that purpose.
This also consequently fixes bug 634592.
This commit adjusts the app chooser code to GTK+ coding style:
- line up prototypes
- remove some excess {}
- remove tabs and trailing whitespace
- add docs
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.
