Now that GDK has the appropriate API, we can simplify the widget drawing
code into a single function.

ddcf47026d widget: No longer postpone style-updated on unrealized widgets
GTK used to not emit GtkWidget::style-updated on widgets that weren't
realized. This sped up construction of complex widgetry in the early
days of GTK3 where we instantly invalidated on every change.
We don't do that anymore, so in theory (and in my limited testing with
widget-factory) this shouldn't be a prolem anymore.

What is a problem though is that postponing style-updated leads to 2
problems:
(1) Unrealized widgets will not emit style-updated which may cause them
    to not properly update their state and return wrong values from
    get_preferred_width/height() etc
(2) Emitting style-updated during realize can happen too late.
    When a widget is not made child-visible by its parent (common
    examples: notebook, paned) it will also not be realized when the
    parent is initially shown. However, when they get realized later
    (after a resize of the parent), they will emit style-updated (and
    potentially queue a resize) during size-allocate.

580ea227a6 widget: Redo drawing code
Previously, we had a special cae to draw subwindows of widgets.

This is not necessary as conformant widgets should be able to properly
render themselves when all windows need to be painted.
From now on assume that is the case.

We therefore paint nonnative GDK windows "inline" by just returning TRUE
for gtk_cairo_should_draw_window() for those windows.

This speeds up hilighting different rows in the listbox gtk-demo example
tremendously (by a factor of 10 or more) as the previous code was
O(<number of non-window subwidgets> *
<number of subwindows>) which in the listbox example were ~15,000 and
~2,000 respectively.

ebdf5f581d widget: Add :focus-on-click property
There are currently three widget that implement such a property, and
there are other widgets for which the behavior can make sense. It

The gesture is hooked to the capture phase, so it works for buttons in

capturing events from, an ugly hack is in place to avoid capturing
events when the target widget has a gesture that would consume motion
events.

235837ad49 gtkwindow: Use actions from focused widget to activate accel
Currently we only take into account the window GActionGroup for
activating the accels.

However, the application could have some custom GActionGroup in the
chain of focused widgets that could want to activate some action if
some accel is activated while that widget is focused.

To allow applications to set accels on widgets that use custom
GActionGroups, simply use the muxer of the focused widget, which
already contains the actions of the parents.

6c49cd0ea6 action stuff: stop abusing GLib's namespace
Rename our internal GActionMuxer, GActionObserver and GActionObservable
classes and interfaces to have names in our own namespace.

These classes were originally intended for GIO but turned out to be too
special-purpose to be useful there, so we never made them public API but
have just been copying them around (without bothering to properly rename
them).  Now that other people will be copying them out of Gtk, it's even
more important to prevent this namespace abuse from spreading further.

bd4d00918e API: Don't export gtk_widget_preferred_size_and_baseline()
gtk_widget_preferred_size() is only useful if you want to quickly port a
widget from GTK2 sizing code to GTK3 but does not properly work with
height-for-width as used in GTK. So we don't want to encourage people to
use it. In particular we want people to convert to height-for-width
before adding baseline support to their widgets.

d22fd7223c Only handle exposes on native window, propagate to children via draw()
We now consider non-native windows non-opaque, which means any invalid
area in a subwindow will also be invalid all the way up to the nearest
native windows. We take advantage of this by ignoring all expose events
on non-native windows (which typically means just the toplevel) and instead
propagating down the draw() calls to children directly via
gtk_container_propagate_draw.

This is nice as it means we always draw widgets the same way, and it
will let us do some interesting ways in the future.

We also clean up the GtkWidget opacity handling as we can now always
rely on the draing happening via cairo.

We can't really just draw by walking down the widget hierarchy, as
this doesn't get the clipping right (so e.g. widgets doing cairo_paint
may draw outside the expected gdkwindow subarea) nor does it let
us paint window backgrounds.

So, we now do multiple draws for each widget, once for each GdkWindow,
although we still do it on the same base cairo_t that we get for the
toplevel native window. The difference is only the clipping, the rendering
order, and which other widgets we propagate into.

We also collect all the windows of a widget so we can expose them inside
the same opacity group if needed.

NOTE: This change neuters gtk_widget_set_double_buffered for
widgets without native windows. Its impossible to disable
the double buffering in this model.

316d450421 Handle non-baseline supporting subclasses overriding baseline supporting classes
If a subclass (say a child of GtkButton) overrides the non-baseline
size request methods we need to call these, rather than the new
get_height_and_baseline_for_width method.

In order to handle this we make the default for this method to be
NULL, and instead check at runtime which method to call. If any
non-baseline vfunc has changed in a class but the baseline one
hasn't, then we can't use the baseline one.
2013-04-23 05:58:48 +02:00
Alexander Larsson
852cbb62b8 Initial support for baselines
This modifies the size machinery in order to allow baseline support.

We add a new widget vfunc get_preferred_height_and_baseline_for_width
which queries the normal height_for_width (or non-for-width if width
is -1) and additionally returns optional (-1 means "no baseline")
baselines for the minimal and natural heights.

We also add a new gtk_widget_size_allocate_with_baseline() which
baseline-aware containers can use to allocate children with a specific
baseline, either one inherited from the parent, or one introduced due
to requested baseline alignment in the container
itself. size_allocate_with_baseline() works just like a normal size
allocation, except the baseline gets recorded so that the child can
access it via gtk_widget_get_allocated_baseline() when it aligns
itself.

There are also adjust_baseline_request/allocation similar to the
allocation adjustment, and we extend the size request cache to also
store the baselines.

d30d56452c GtkWidget: Add gtk_widget_insert_action_group()
This allows adding a GActionGroup with a given name at an arbitrary
point in the widget tree.

This patch also adds an internal _get_action_muxer() API.  Calling this
will create a GActionMuxer associated with the widget.  The parent of
the muxer will be the muxer of the widget's conceptual parent.  For
non-menus, that is the normal parent.  For menus, it is the attach
widget.

In this way, we end up with a hierarchy of GActionMuxer that largely
reflects the hierarchy of GtkWidget, but only in places that the action
context has been requested.  These muxers are the ones on which the
inserted actions groups are installed.

A following patch will add a user of this API.

9f4bfff1b0 gtk: Add a way to do event capture
This patch adds a capture phase to GTK+'s event propagation
model. Events are first propagated from the toplevel (or the
grab widget, if a grab is in place) down to the target widget
 and then back up. The second phase is using the existing
::event signal, the new capture phase is using a private
API instead of a public signal for now.

This mechanism can be used in many places where we currently
have to prevent child widgets from getting events by putting
an input-only window over them. It will also be used to implement
kinetic scrolling in subsequent patches.

http://bugzilla.gnome.org/show_bug.cgi?id=641836

We automatically request more motion events in behalf of
the original widget if it listens to motion hints. So
the capturing widget doesn't need to handle such
implementation details.

We are not making event capture part of the public API for 3.4,
which is why there is no ::captured-event signal.

This function returns the accessible if it already exists. This way we
can call functions on the accessible from the widget itself instead of
having to rely on signals.

38b5c8cf45 Cache heights-for-range-of-widths instead of height for every width.
This patch optimizes window resizes by assuming that if a widget
has the same height at a width of 50 as with a width of 150, the
height for width 100 will also be the same.

The patch also further optimizes the cache allocator, now there
are 2 pointer arrays of up to a maximum of 5 requests, the arrays
will only be allocated if a request is ever made in that orientation
and the array will be sparse until each request is made (i.e. if a
label can only wrap to 3 lines, there will only be 3 out of a
possible 5 SizeRequest structures allocated to cache it).

82ae7b77ca Reduce memory consumption of the size request cache.
This patch makes contextual height-for-width request caching
optional (the contextual cache is not allocated for widgets that
report GTK_SIZE_REQUEST_CONSTANT_SIZE).

1c20c93423 Optimize queue_resize_on_widget()
Optimized GtkSizeGroup code that is invoked for every queued resize
and every request that is not previously cached by trading qdata on
widgets for 3 extra bitfields on the GtkWidgetPrivate structure.

001697a22a Move the get_cursor_color in GtkStyleContext
Move the private get_cursor_color method belongs to StyleContext. Change
the api so that retrieving both primary and secondary color is possible.
I left the method private for now, though it should probably be public
as all the other getters.

2cc059a0e7 Split off gtkprivate.h
The gtkprivate.h header contains GtkWidget-specific private symbols that
are not useful except in a handful of cases. Basically everything
includes gtkprivate.h for the GTK_PARAM_* macros.
