Although, you can use:
gtk_widget_get_parent_window (gtk_bin_get_child (GTK_BIN (widget)))
there already are gtk_tree_view_get_bin_window() and
gtk_layout_get_bin_window() in GTK+ api.

When GtkMisc padding is set on an image, the optimization for only
recalculating size after a clear() breaks, since the requisition is
not (0, 0). We need a separate 'need_calc' flag.
Every call to _gtk_file_system_model_new*() gets the same list of column types,
so we now keep the list in a macro instead of having duplicated copies all around.

The old semantics was to return a GFile* owned by the file system model; the new
semantics is to hand out new references whenever possible.

There was some confusion between "index" as used for the model->files[] array,
and node->index as used for our 1-based row numbers. Now we use "index" only
for indices in the model->files[] array, and node->row for row numbers. Functions
and variables are renamed to clarify whether they refer to indexes or rows.

The non-standard "filechooser::mime-type" was a remnant of the recent-files code using
a hand-built GFileInfo; now we just query the file info ourselves.

g_array_new() doesn't reserve any size by default, so during the initial population
of the file array, we'll do more reallocs than strictly needed. We'll start with
a reasonable preallocated size, in this case the number of files which we can
get in a single chunk out of GIO.

There's no point in running a GtkFileSystemModel with invalid column types.
This way we can also avoid clearing the memory of the column_types array.

The previous function enumerated the whole directory and used a lot of
outdated API to decide how to show files.
The new code queries the filesystem model to decide about this.
The now unused old functions were removed.
Previously information about file sizes was not available for search
results and recent files, so the column was always hidden. As this
information is now available, we can stop the special handling and use
the same setting as in browse mode.
Use the faster _gtk_file_system_model_get_value() function instead of
gtk_tree_model_get() inside the sort functions. This gives a significant
speed-up when sorting large lists.
In a test case with 40.000 files, the sorting time went from ~5 seconds
to less than 0.5 seconds for my test case. There is 2 significant
problems with gtk_tree_model_get() that cause this:
1) The value is copied, which takes quite a bit of time for strings.
~25% of excessive time or ~1 second in my test
2) The tree model functions need to lookup the interface vfunc. And
gtk_tree_model_get() doesn't do that only once, but multiple times
(verifying column id, getting the actual value, ...)
~75% of excessive time or ~3 seconds in my test
Replace the list model code with the file system model and use all the
file system model API niceties we get from that.
Also adds the function _gtk_file_system_model_add_and_query_file() which
g_file_query_info()'s the file before adding it, so it gets added with
the right information.
Since the time taken by g_file_enumerate_children() depends a lot on the
attributes that are queried, we query the minimum attributes that need
to be queired to display the file chooser.
In particular, the attributes for loading the icon are ignored, as icons
are loaded on demand (see previous commit).
Because loading icons takes a noticable performance, this code loads the
pixbuf on demand and only loads icons for rows that are visible. There
is a few caveats to this:
- The pixbuf cell renderer must report the proer size even if the icon
is not yet loaded. This is achieved by setting a fixed size.
- On theme changes the cahced pixbufs and the cell renderer must be
updated to conform to the new theme.
Previously, there was a GtkTreeSortModel wrapped around the filesystem
model to make it sortable. As the new implementation implements the
GtkTreeSortable interface, we can use this instead.
A lot of code special cases accesses to the tree view for the different
browse modes, which was previously necessary, because the models were
different. Now that they are identical in the first columns, there is no
such need anymore, and the functions don't need to be special cased.
Previously custom functions were used to compute the data passed to the
cell renderers. Now that all this data is saved by the tree models with
compatible nodes, the usual default attribute-to-column mapping can be
used.
With this, caching of the values can happen in the tree model, which
avoids costly lookups of icons or computation of strings. Last but not
least it avoids spurious bugs that could happen when strings changed
without anyone noticing, like the mtime when a new day begins.
All tree models in browse mode now share the first 10 column types
containing all the necessary information to display the model on screen.
Therefor it is now easy to just operate on the tree model associated
with the file tree view and in most cases it isn't necessary anymore to
special case the browse modes.
The new model is mostly API-compatible with the old model (minimal
changes were required), but is a lot faster and has a lot of very
desirable features.
- the model does no longer support a tree, just a list of files in a
given directory
- the storage has been moved to a GArray as opposed to a tree
- no more dependency on GtkFileSystem
- columns are managed by the creator of the model, so any number of
nodes can be added as needed. This also makes the API more similar
to GtkListStore.
- Values are filled on demand using a function given when creating the
model.
- The function can decide to let the model cache returned values or
decide to be called again the next time the value is queried.
- implements GtkTreeSortable
- _gtk_file_system_model_get_value() was added to significantly speed
up value access, which is necessary when sorting large models.
Add API for GtkDialog to return widgets by response ID.
Added gtk_dialog_get_widget_for_response() to access to all kinds
of buttons with all kinds of responses.
Zero width/height is unsupported and will magically be turned into one.
For instance, gtk_widget_size_allocate() will eventually do this magic
on the value stored in widget->allocation.
However, if we don't do this magic conversion early, then the value
returned from gtk_window_compute_configure_request() will not be
comparable with whats stored in widget->allocation. (I.E. they will
differ if width or height are zero).
This is dangerous, as we do such a comparison in gtk_window_move_resize().
Currently a change from e.g. 10x1 (current allocation) to 10x0 (new size)
will be expected to produce a ConfigureNotify, when it actually won't,
thus never thawing the frozen toplevel.

Like the other GtkSettings already registered, these are influenced from
the outside and cannot be properly tested. The defaultvalues test
passes again now.
gtk_tree_model_build_level() always needs to emit row-inserted when
requested, this should not depend on whether the level has a parent
level or a virtual root, which is a check whether or not we need to
reference the node in the child model. Furthermore, we also need
to emit row-has-child-toggled after row-inserted when appropriate.
When gtk_tree_model_filter_row_changed() pulls in the root level, it
must request build_level() to emit signals for this. The refilter
function uses row_changed to process the changes, so build_level() in
the first call to row_changed() might pull in multiple new nodes in this
scenario, for all of these signals need to be emitted. Of course,
build_level() will then also emit the signals for the node row_changed()
is processing, we should not emit a duplicate signal, this is now
accounted for.
Add a unit test for this. For this small functionality to block the
row-changed signal has been implemented, so that we can simulate calls
to the refilter function using the current visible column setup.
_gtk_tooltip_handle_event, which is called for many events in the GTK+
main loop, calls gtk_tooltip_set_last_window, which keeps a weak
reference to the last window we passed through. If the window being
set is the same than the last one there's really no need to update our
weak reference, so add a check for that and exit early.
Check for 'auth-info-required' attribute from printer attributes to
find out whether an authentization of user is needed.
Change password dialog of print backend to be able to require informations
requested thru 'auth-info-required' (#566522).
This patch tests availability of remote host before getting ppd file
for selected printer (#586207). It also adds a state message for
failure of getting details.
progress-border and invisible-char style properties had wrong amount
of colons for gtk-doc (signal markup instead of properties), so the
Since tags didn't seem to get picked up.
GtkEntry:invisible-char also had a wrong Since: 2.22, fixed to 2.18.
With Bug 302240, a check was added to avoid keynav to unrealized
radio buttons in the group, but that's not the right check - the
check should be on MAPPED instead, since a widget can be realized
even if it, or a parent, is hidden. Bug 595599
Applications using non-double-buffered drawing using cairo (e.g. Abiword)
can draw directly to the window using cairo and thus manage to avoid
the automatic flushing of outstanding moves. This can cause redraw
inconsistencies like bug 593507.
We fix this by always flushing when exposing non-double-buffered widgets.
Fixed the button-sensivity patch done to GtkComboBox to account for
changes in appearance (changes to the appears-as-list style property).
Also, in list-mode, the event box that has been created below the cell
view also needs to have its sensitivity updated.
Commit 3f306a4042 made it possible for
gtk_tree_view_top_row_to_dy() to be called recursively. (In a different
way than was already guarded for). This caused a single test case in
the scrolling test suite to fail. We now also guard for recursive calls at
the beginning of gtk_tree_view_top_row_to_dy().
Rework the sort and filter models to store their reference to the parent
element as an array index instead of a pointer to an array element.
These pointers could become invalid with any array modification, whereas
indices do not.
If we have a level with zero visible nodes and the first node becomes
visible in that level, then parent has just become a "real" parent node.
In such a case we need to emit row-has-child-toggled. This only applies
to non-root levels that have a parent. This problem was also found when
writing the unit test, the respective cases in the unit test have been
corrected.
This fixes bugs:
Bug 372010 - Filtering not working properly
Bug 525965 - Filtered and sorted GtkTreeView is missing rows
When a filter function is used that determines the visibility property
of a node using whether or it it has children, the state of this node
very likely changes when the filter model receives a
row-has-child-toggled signal. Therefore, we need to handle state
changes in the row-has-child-toggled handler.
