If a range goes all the way to the edge of the screen then we don't
have any way to activate autoscrolling. By adding a small region
at the ends of the range we can handle this case. This is the same
approach used in treeviews.
The newly-added gtk_flow_box_child_is_selected() needed to return a
gboolean, so use g_return_val_if_fail() to return FALSE when an invalid
GtkFlowBoxChild* is passed in.
Make flowbox selection more orthodox. Control and Shift now
modify the selection behaviour pretty much in the same way
they do in a tree view, and clicking without modifiers will
clear the selection.
When dealing with touch devices, we treat modifier-less events
as modifying the selection.
This commit also adds a few other selection necessities, such
as catching Escape key presses to cancel rubberband selection,
and handling grab notify.
GtkFlowBox is a container that its children in a reflowing
grid, which can be oriented horizontally or vertically.
It is similar to GtkListBox in that the children can
be sorted and filtered, and by requiring a dedicated child
widget type, GtkFlowBoxChild. It is similar to GtkTreeView
in that is supports a full set of selection modes, including
rubberband selection.
This is the culmination of work that has happened in the
egg-list-box module, and earlier in libegg. The origins of
this code are the EggSpreadTable in libegg, which was written
by Tristan van Berkom. It was moved to egg-list-box and
renamed EggFlowBox by Jon McCann, and I gave it some finishing
touched in the flowbox-improvements branch of that module.
Previously, the "Places" sidebar was populated by the update_places()
call from within gtk_places_sidebar_style_set(). After
742a2f11a9, update_places() is never called
and the sidebar is never populated unless gtk_places_sidebar_add_shortcut()
happens to be called. This commit fixes this by calling update_places()
at the end of gtk_places_sidebar_init().

GtkWidget had a hack where if opacity is 0.999 we set up an opacity group when
rendering the widget. This is no longer needed in 3.10, and GtkStack doesn't
use it anymore.
GdStack is using it, so applications should be ported from GdStack to GtkStack
in 3.12.
https://bugzilla.gnome.org/show_bug.cgi?id=703603
Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.

Add a has-tab-gap style property to GtkNotebook so that we can
disable drawing the gap between tabs and the page in the Adwaita
theme without breaking existing themes.
https://bugzilla.gnome.org/show_bug.cgi?id=707920
GtkSourceView draws before chaining upo to GtkTextView and assumes
that this will be visible, but the pixelcache will just overdraw
that with background.
So, we stop drawing the background to the pixel cache and instead
make it an CAIRO_CONTENT_COLOR_ALPHA surface to make the previously
drawn content see through.
This is slower, but more backwards compatible.
https://bugzilla.gnome.org/show_bug.cgi?id=708423
Previously, we were showing and hiding the custom titlebar
widget in response to state changes such as maximization.
Instead, use gtk_widget_set_child_visible() and leave
show/hide to applications. This makes it possible to set
a custom titlebar and hide it, for a titlebar-less appearance.
https://bugzilla.gnome.org/show_bug.cgi?id=707132
When loading a symbolic icon, g_file_get_contents() is currently used
with the icon pathname, to load its SVG data. This won't work when the
icon is not a local file, for instance when a symbolic icon is loaded
from a GFileIcon with a GResource path.
Fortunately GtkIconInfo already holds a GFile, so we can just use
g_file_load_contents() to load the data instead.
https://bugzilla.gnome.org/show_bug.cgi?id=709056
Updated documentation to specify that '0' should be specified if
one does not need to automatically assign a bound child to a public
or private instance member (now that negative values are private
structure offsets).
If we start with a padding of -1 then it can leak out of the size
allocation request for the column when the treeview is empty. The
GtkTreeView will then collect these -1 values and add them together,
returning -n where 'n' is the number of columns.
This is usually not a problem because treeviews tend to be used with a
scrollbar and the width of the scrollbar will be added to this number
bringing it into positive territory again. On Ubuntu, with overlay
scrollbars, this is not the case, however.
https://bugzilla.gnome.org/show_bug.cgi?id=703062
The size of the shadow and invisible borders can (and usually
will) change between backdrop and focused windows, while the
overall window size remains unchanged. This causes the visible
window to visually 'jump'. We can avoid this by always reserving
the maximum of the focused and unfocused border sizes. The code
for positioning the input-only windows making up the invisible
border is adjusted to deal with this. We now always place the
invisible border right outside the visible content, even if the
shadow extends out much farther.
https://bugzilla.gnome.org/show_bug.cgi?id=707524
And use the "header" style class to do that.
This allows themes to set e.g. the background of the tab header
differently.
Themes will need slight adjustment to make things appear
as before.

This allows subclasses of GtkTextView that require a corresponding
subclass of GtkTextBuffer to automatically do the right thing when
constructed with a NULL buffer. An example of this is GtkSourceView
which requires a GtkSourceBuffer.

The GtkStack and GtkStackSwitcher code did not really
follow GTK+ conventions for includes. Fix that, and also
fix up a case of gpointer vs gpointer* confusion
in gtkstack.c.
This adds new 'over' and 'under' transitions which work by moving
the new page over the previous one, or moving the previous page off
to reveal the new one. We also add an over/under combination that
is going to be used in GtkAboutDialog.
https://bugzilla.gnome.org/show_bug.cgi?id=707187
Some of the labels were not marked as no-show-all. But the
code clearly tries to manage their visibility, so gtk_widget_show_all()
should not affect them.
https://bugzilla.gnome.org/show_bug.cgi?id=681484
The child property is watched by the StackSwicther which in turns sets a
needs-attention css class on the corresponding button, so that the theme
can for instance show a throbbing animation if one of the hidden pages
needs the user attention.

If an icon is in a Fixed or Threshold directory we normally don't
scale it. However, in the case of HiDPI scaling we *do* want to
scale it, to avoid different layouts in Lo/HiDPI. We look up whatever
the size of the icon would have been in LoDPI and scale to that
in the no-scaling case, thus getting the same layout as the
unscaled case.
https://bugzilla.gnome.org/show_bug.cgi?id=708384
GdkPixbuf will fail returning %NULL if we try to scale a pixbuf to (0, 0),
which will then trigger an assertion in gtk_icon_info_load_icon_finish();
we never want a scale of 0, so ensure it is at least 1.
https://bugzilla.gnome.org/show_bug.cgi?id=708384
We need to subtract border_width from the size we're passing to the
children hfw functions as those are added by ourselves.
Fixes the window-border-width.ui reftest.
Previously, when you clicked and held the button down on a
GtkExpander's label or disclosure triangle, then moved the mouse
away and released the button, the expander would still activate.
This brings the behavior in line with the more generally expected
behavior, as exhibited by GtkButton for example.

This allows GTK+ applications with headerbars to fit in
better in platforms that have window controls on the left.
To use this, set -GtkWindow-decoration-button-layout: 'close:'
in the theme.
https://bugzilla.gnome.org/show_bug.cgi?id=706708
At least for header bars, there's often application controls
in this area, which should be included in the focus chain.
We make it so that the initial focus avoids the titlebar,
but tabbing around will eventually get there.

This reverts commit 7cecc8e524.
It is impossible to use the selection object of the menu while it is
collapsed (collapsed menus deselect everything for a start), so even
though the original patch was correct, the followup issues are too big
to solve this quickly to a release.
https://bugzilla.gnome.org/show_bug.cgi?id=707786
* gtk/gtkwidget.c: drag-leave signal: Document that it is called before
drag-drop.
drag-data-received signal: Document that it is up to the application
to know why the data was requested (e.g. drag motion or drop).
* demos/gtk-demo/toolpalette.c: interactive_canvas_drag_drop():
Do not transform the drop_item created in the drag-motion handler.
Instead caused drag-data-received to be called, remembering why,
and create a new item there.
interactive_canvas_drag_leave(): Remove the idle-handler hack,
now that we do not need to keep the drag-motion drop_item alive until
the drop.
I noticed that this patch was sitting in bug #605611 from 2009
though it had been approved. I do not remember much about why I
created it.
This is the same behaviour as gtk_widget_get_valign, except
we have no gtk_wiget_get_halign_with_baseline, as baselines make
no sense for halign.
Without this some widgets (like e.g. GtkOverlay) crash if you accidentally
set a BASELINE halign.
It is more logical to first delete the selection and then pasting the
text. When the selection and the text contain tags, the new behavior is
more natural.
A segfault in paste_from_buffer() is also avoided. The segfault occurs when
the text to paste is deleted because it is the selection.

Move GtkWrapMode from GtkTextTag to the GtkTextView section. The wrap
mode property is in the text view.
Links to the "mark-set" and "mark-deleted" signals.
Add a precision about gtk_text_buffer_get_iter_at_line().
Fix typo in gtk_text_tag_set_priority().

A proper name or label is required. In the same way, if the
widget is labelled, ATs uses to expose both the label and the
name, making the final output not really user-friendly.

keyboard navigation didn't support activation since we moved
the keynav to the child row widgets. We fix this by adding a
activate signal handler for the row and setting
widget_class->activate_signal to it.

This reverts commit 70ac2b24c3.
It turns out the correct fix is to make pango_layout_get_text() not
return NULL. This has been done, so we can drop this patch.
I won't bump the Pango dependency in configure.ac for this as I don't
consider the crash critical enough.
Use the pixelcache rendered area to inform what part of the cache should
be invalidated upon changes to the underlying textlayout.
By rendering the background to the pixelcache, we can avoid the need to
use RGBA content.
Also, we're using the pixel cache on the text windows bin_window (see
gtk_text_view_get_window) so we need to register the invalidation handler
on that, otherwise the region passed to the invalidate handler will get
clipped to the visible region.
https://bugzilla.gnome.org/show_bug.cgi?id=707244
We added code to look for settings.ini in system config dirs,
and then proceeded to move it to /usr/share/gtk-3.0 :-(. So,
look in that location as well.
We now pass NULL when the current color should be the default value of
the "color" property and we haven't looked up any value yet. This way we
don't need to look it up all the time and more importantly we can
resolve the default color, which is required because it's a
GtkCssColorValue and not a GtkCssRgbaValue.
Fixes assertions triggering at Polari startup.
The version of device scale that landed in upstream cairo
master already inherits the device scale in cairo_create_similar,
so no need to do that in gtk anymore.
Even when not following states, blacklist the states we don't follow
instead of whitelisting the ones we do. This way, we don't accidentally
eat new ones like the text direction flags.
Fixes a bug where text direction wasn't available when rendering stock
items.

Call gtk_widget_get_mapped() in a couple of places before looking at the
widget's parent, since it might be set to a widget that has been
finalized, causing an invalid read.
GTK+ tries to automatically assign the best input module based on the
'system locale'. In the specific case of the IME input method, it will
be the default for the whole GTK+ application if the system locale is
either Japanese (ja), Korean (ko) or Chinese (zh). Other defaults are
equally applicable, e.g. if system locale is Catalan (ca), the special
'Cedilla' input module is chosen.
System locale can be changed (e.g. Win7) through the following sequence
(reboot required):
Control Panel
Region and Language
Administrative
Language for non-Unicode Programs
Change system locale...
The problem with this behaviour is that changing the 'default input
language' (e.g. from English to Japanese+IME) doesn't affect the GTK+
application. Therefore, I can have an English system locale (where GTK+
will choose Simple IM by default) but then have Japanese+IME as input
language.
Default input language can be changed (e.g. Win7) through the following
sequence (no reboot required):
System locale can be changed (e.g. Win7) through:
Control Panel
Region and Language
Keyboards and Languages
Keyboards and other input languages
Change keyboards...
Default input language can also be changed using the language bar directly.
So, instead of using the system-wide default locale to decide which input
method to use as default, better use the input language specified by the
user, which may be the same as the system-wide default locale, or different.
Following the previous example, with an English system locale and a
Japanese+IME input language, the default input method will now be IME
instead of Simple, which is closer to what's expected by the user.
This change only affects the application during startup; i.e. if the user
changes the input language while the application is running, we wouldn't be
changing the default input method to use. We could do this processing the
WM_INPUTLANGCHANGE messages, though.

finalized, causing an invalid read.
GtkAssistant is bending the rules about child properties
of non-direct children, and the recent fix to accomodate
GtkInfoBar changes broke things. The effect was that child
properties of assistant pages in ui files were just not
applied, so all pages ended up without titles and with
the normal page type, leading to broken assistants all
over the place.
