Implement GtkFileChooserNative for sandboxed applications
by talking to org.freedesktop.portal.FileChooser. Currently,
this supports OPEN and SAVE mode.

The gtk_show_uri API doesn't let us specify a parent window. With
portals, there may be an intermediate dialog, for which it is nice
to have parent window information, to place it properly.

If we have an application that never goes idle (or takes a long time to
go idle), the close buttons in CSD decoration don't work properly.
While it's not clear why the usage of an idle was added in the first
place, keep on using it to avoid unexpected reentrancy problems, but
change the priority to G_PRIORITY_DEFAULT.

Our property parser stops at the first match when looking for
enums, so we need to order our values so that we don't end up
with prefixes of longer names being found first.
I noticed this when the parser tried to interpret
background-blend-mode: color-burn; as "color, with junk at the end".
It also affects animation-direction, which is also fixed here.
CSS supports blend modes, in which a series of layers are
merged together according to the given operation or set of
operations.
Support for blend modes landed on Cairo, which exposes all
the commons and also the exquisites blend modes available.
Adding support for blend modes, then, is just a matter of
using the available Cairo operations.
This patch adds the background-blend-mode CSS enum property,
and adapts the background rendering code to blend the backgrounds
using the available blend modes when they're set.

Xfce4-session-manager added support for managing dbus based clients.
This patch adds support for checking if Xfce session manager is
around after trying the gnome one.

I was struggling to understand why calling
gtk_print_unix_dialog_set_manual_capabilities (...,0)
was not having the expected effect of hiding the preview
button. The initial capabilities were not applied at all.
commit 0015ebc4a8 reworked
some of the titlebar size allocation code. Those changes
inadvertently introduced a warning when the application sets
the headerbar title widget to be hidden.
This commit fixes that warning.

This partly reverts 9f5b9c0e07, which
removed the check for GtkWidget-window-dragging in the multipress
gesture. This check is still needed for widgets which have this style
property set (e.g. menubars and toolbars) can maximize the window on
double click -- but those widgets which have it set to FALSE shouldn't
maximize the window.
Use G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE to detect remote filesystems
instead of hardcoded list of filesystem types.
Bump required GLib version accordingly.

...or warning style class applied.
This particular style bit wasn't converted to the saner 3.20 way
so `entry:selected` used in place of `entry selection`.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=768025
we used to style infobars by using the .info, .question, .warning
and .error selectors directly, which used to be ok when we had just
styleclasses all over the place, now it needs to be more specific
or it interferes with everything with those styleclasses applied
like entries.
The header bar currently ignores the expand property on its
children. This commit changes the code to honor that property.
It divvies up any free space and distributes it equally to packed
children (with any left over space given out a pixel at a time
on a first come, first serve basis).
This commit also adds support for the title widget to be made
expandable.
It accomplishes this by using up the padding the title widget
is centered with.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
In order to support the expand property on children, we're
going to need to look at the size of the packed children
on each side of the title widget, up front, before allocating
them (to compute how much extra allocation each expanded child
gets).
This commit lays the groundwork for that analysis by splitting
the size calculation of each side of the header bar outside
of the loop that allocates each child of the header bar.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
With a headerbar, the widget in the center may be a label, constructed
internally, or a custom widget, constructed externally. The size
allocation code needs to handle either case the same way for the most
part. There's more than one place in the code that checks which of
the two widgets to use and does some operation on the selected one.
This commit simplifies the code by checking up front which one is the
center (title) widget and storing that in a temporary variable,
This allows reducing duplicated logic later on in the function.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
There's some extraneous MIN() calls that have predetermined answers.
This commit drops them and then simplifies a few redudant checks into
one MIN call.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
The size allocation code maintains an array of two elements,
to track the allocation of children packed into the two sides
of a header bar. Sometimes this array is indexed with 0 and 1,
and sometimes its indexed with GTK_PACK_START and GTK_PACK_END.
The latter happen to have the values 0 and 1, respectively, but
that's not really obvious.
For clarity, this commit changes the code to index those arrays
consistently, sticking to 0 and 1 across the board.
It's only possible to have a label or a custom title, not both.
The size allocate code confusingly treats them as independent.
That is confusing, because, as the code is written, it makes it
look like the space for the custom title isn't getting accounted
for.
This commit else-ifies some parts of the size allocate code for
clarity.
Firefox does a bunch of interesting things with GTK.
If the top-level GtkWindow does not have a "csd" style class associated,
Firefox will happily draw the contents of the container used to render
HTML and XUL directly on the top level's GdkWindow; on the other hand,
if a "csd" style class is found, the MozContainer will create a new
child window, and draw on it.
Then, Firefox will proceed to disable double buffering on both the
top-level window and the MozContainer (unless they are backed by the
same GdkWindow, in which case only the top-level will be
single-buffered) *and* it will add a GDK_EXPOSURE_MASK flag to the
MozContainer events for good measure (even if this is only needed for
GTK+ 2.x).
After landing the GdkDrawingContext API in GdkWindow, GTK enabled
automatic double buffering on all top-level windows backed by a native
surface, ad most users of single buffering rely on child widgets instead
of top-levels, and we'd still like to have the same double buffering
behaviour for all top-levels on all backends. Obviously, with Firefox
disabling double buffering on the top-level window, the change broke
their drawing mechanism.
Ideally, Firefox could be fixed to not disable double buffering on the
top-level window when MozContainer has a separate GdkWindow — i.e. the
CSD case — but since we did introduce a slight change of behaviour in
fringe users of the GTK+ API, let's keep backwards compatibility with
the old code for a little while longer, and create an intermediate Cairo
context unbound from the GdkDrawingContext, like we used to do until
GTK+ 3.20.
And ensure it's still visible before returning the keyboard focus to it.
Because of the extra ref, add a dispose handler that will ensure the
ref is lost (by popping down), although this should be already ensured
through other paths (eg. when the popup widget loses visibility).
This fixes a possible crash in dispose paths, where we might be restoring
focus on an already destroyed widget, and at a time where, if the toplevel
is being itself disposed, no new focus should be set.
https://bugzilla.gnome.org/show_bug.cgi?id=767849
If there are widget margins set, the whole popover will be displaced.
However the calculation of the tail position doesn't have this into
account, ending up with the tail being detached from the popover if
the margin grew too big.
We should not render the arrows invariably next to the GdkWindow edge,
but optionally displaced inside it depending on the widget margins.
Fixes the gtk3-demo "Popovers" demo case, whose GtkEntry popovers set
widget margins for some reason.
https://bugzilla.gnome.org/show_bug.cgi?id=767851
do_sort will crash if sort_func is not defined. Instead of adding a check
there in the hot path, just check for sort_func before invalidating the
sort of the underlying GSequence.
I noticed that some of the gestures did not show up in the
search results in the builder example in gtk3-demo, because
they share the same title and don't have an accelerator to
disambiguate. Include the shortcut type to handle this case.
The cellrenderer signals might be taking the grab somewhere else, at which
point it's dubious we should attempt to take the keyboard focus into the
treeview.
This concretely breaks popovers triggered from cellrenderer signals on
button press, because the treeview will attempt to grab focus
inconditionally then.

It's almost certainly a programmer error if an action isn't
activatable because its target and parameter type don't match.
This commit changes the existing g_message to a g_warning.

Previously a style cascade's parent could not have a parent itself. That
represented the two levels at which you could add a style provider: at
the screen level, with gtk_style_context_add_provider_for_screen(), and
at the style context level, with gtk_style_context_add_provider().
This commit changes no functionality, but this change will be necessary
for adding style providers in the future that apply to a subtree of the
widget tree. It relaxes the requirement that a style cascade's parent
must not have a parent, since in the future a style context may be
affected by any number of parent widgets' style contexts.

This is a bit of fallout from 34feba1, now that we resolve
the has_indicators value earlier than realize, it becomes
possible to call gdk_window_move_resize() before realization.
Just added the appropriate checks.
Instead of associating the GdkWindow that created the GdkDrawingContext
we can directly bind the Cairo context to the GDK drawing context.
Cairo contexts created via gdk_cairo_create() go back to not having a
GdkWindow associated to them, like they did before we introduced the
gdk_window_begin_draw_frame() API.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Instead of giving out Cairo contexts, GdkWindow should provide a
"drawing context", which can then create Cairo contexts on demand; this
allows us to future proof the API for when we're going to use a
different rendering pipeline, like OpenGL.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Widgets should support size requests before being realized in general,
otherwise this can cause flicker/resize at initial display time as
the toplevel window can make a request before realize/allocate.
This also makes the added testsuite/gtk/scrolledwindow.c test work again,
this was broken because we only ever calculate whether we are going
to use overlay scrollbars once the scrolled window is realized (and
the test case does not realize any window).
This patch does a couple of things:
o Removes the obscure 'extra_width' and 'extra_height' variables
making the request code exceedingly difficult to read
o Fixes the max-content-size properties introduced in bug 742281
so that they do not grow the minimum request.
o Cleanup of request code in general:
- min/max content sizes are clamped around the child request as needed
- scrollbar requests are only added in one place, after child request
sizes are calculated and without the extra_width/height thing.
