Async callbacks are delivered in idles, so we need to make sure
we get the gdk lock before calling any gdk/gtk stuff. This was
missing in a few places.
Dumps the widget path into a string representation. It tries to match the CSS
style as closely as possible (Note that there might be paths that cannot be
represented in CSS).
The main use of this code is for debugging purposes, so that you can
g_print() the path or dump it in a gdb session.
This ensures that widgets that aren't ported and rely on the style-set
signal being emitted work as well as before. They should not rely on
style-set being emitted however.
Note that this function is a no-op if the initial style has been set
already and is very cheap if it has not been set yet. It only becomes
relevant if the resulting style actually gets used.

The intention of this patch is to make the code clearer, shorter and
most of all to avoid recreating the widget path and setting it path
twice on the style context when the style context was recreated.
Now that we have wesome macros in glib 2.0, we can use them. Woohoo, GTK
2.0 will be so awesome in the future.
(Did anybody touch dnd code this millenium?)
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).
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).
The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
gtk_settings_get_default() was used to monitor the
"gtk-application-prefers-dark-theme" setting, rather
than the GtkSettings object associated with the window's
screen.
Fixes Bug 639584 - initial emission of GtkWidget:style-set is
not happening.
GtkWidget was filtering out ::style-updated (and ::style-set)
emissions until the widget was realized in order to avoid often
useless updates during widget construction and placing.
This is now done instead until the widget has a parent/screen,
which ensures the initial emission happen prior to the first
size negociation, while still filtering out all early emissions
during construction.
You can select something, but moving the focus somewhere else, or bringing up
the context menu makes the selection go away. This makes it impossible to
copy-paste the text.
The reason for this regression is that gtk_label_state_changed was sloppy and
assumed that it would only ever be called when a labels goes insensitive, which
is no longer the case.
The patch fixes things by explicitly checking if the widget is insensitive, and
only resetting the selection in that case, which is the same behaviour we have
for e.g. GtkEntry.
