With pango handling changes to the PangoLayout there now is no
style changes that can affect the layout for the entry, so we don't
have to reset the layout whenever the style is updated.
Now that Pango tracks changes to the context automatically there is
no need to do it manually in e.g. style-updated or direction-changed,
in fact the only case we have to care about is when we re-create
the PangoContext due to a screen change, so we only have to clear
the layouts in GtkLabel in screen-changed.
This means we're not clearing all the layouts whenever the state changes,
which happens to every widget when the window is unfocused, which helps
performance a lot.

This is for a very simple reason: The getter is returning a const value
and the font isn't const anymore. So we need to store the font
description somewhere but we can't reuse it as it's changing all the
time (yay animations, yay inherited values). Sucks.
So keep the hack in here but deprecate the function.
Instead of using gtk_style_context_get_font() in
pango_context_get_metrics(), use pango_context_get_font_description().
The context contains the font description we are about to use after all.
This is necessary because values in a GtkCssComputedValues can change
now. So if the font-size is inherited or animated, the cached value will
be outdated.
Fixes the fontchooser preview not updating.
This means reffing the root in the set property implementation,
rather than in the constructor. We don't need to unref the root
on set, as it's a CONSTRUCT_ONLY property.

GtkWindow always queues a resize on style updates if there is
a grip, because it may have been the grip size style properties
that changed. However, even if it *were*, and it likely wasn't
that would not affect the windows size request, so no need
to queue a resize.
queue_resize basically tells the parent widget that it may need
to pick a different size/layout. However, for a hidden child widget
that should never be needed. It may be that the widget is in a
sizegroup that has ignore_hidden == FALSE though, so it may
affect the size group calculations.
However, if a widget is not visible and not in a size group then
its safe to avoid the resize, as the widget will be resized on
becoming visible anyway.
This avoids a lot of size allocation for hidden things like menus
and tooltips.
Almost all array computations lead to no changes (99% in nautilus)
so we avoid the upfront allocation and delay it until we know its
needed. This drops the allocate/free from the profile.
These are internal apis, and any external issues should have been
caught by checks at public API points. We use the internal checks
here because these checks show up in a non-neglible way on profiles.
pasteboardChangedOwner is not called as reliably as we'd want to get it,
so keep track of [pasteboard changeCount] and drop clipboard ownership
when a change happened. Also better unset the clipboard content redundantly
in a few places rather than missing one, and reorder the code in
gtk_clipboard_set_contents() so that the new aggressive unsetting
won't unset the clipboard under our feet when we call
[pasteboard declareTypes].
(cherry picked from commit f2b74db5dc)
We now support the keywords (like xx-small, medium, larger, smaller...)
and I've changed the default value to be "medium".
This required some shuffling of the "get default font size" code. But
all is well now.
The default font is no longer handled like a custom style sheet that
overrides everything, but as the initial value. This is the same
behavior as in web browsers.
And it allows the theme to actually use the 'font-family' and
'font-size' properties. Of course, a well behaved theme will respect the
setting as much as possible and for example use relative font sizes
(which aren't yet supported, but will be soon).
This gives a GtkSettings object for resolving system-dependant things -
like the default font family and font size.
No code does this yet, but we have an API.
Only GtkSettings implements this.
Now we use the selector tree everywhere, so there is no need to
keep around the linear selectors unless we're using them to
verify the tree correctness, so free them.
We add some "artificial" ordering to the otherwise unordered
tree nodes. This means the tree will be the same every time for the
same input. This is good because e.g. tree order affects the
reordering of the simple selectors, which may affect how
css providers are printed, which need to be consistent for
the css tests to work.
When building the tree we generally reorder the selectors inside
the same simple selector in order to pick a good first selector
to balance the tree better. However, some kinds of selectors
can't really be reordered, even thought they are simple.
This is since the matching code for some types handle
the existance of a directly preceeding selector differently:
REGION and ANY selectors look for a DESCENDANT previous
POSITION selector look for a REGION previous
From a set of GtkCssSelectors and the rulesets they match to
we create a large decision tree that lets us efficitently match
against all the rules and return the set of matched rulesets.
The tree is created such that at each level we pick the initial rule[1]
in all the considered selectors for that level and use put the
one that is in most selectors in the node. All selectors matching that
are put in the previous part of the tree.
This returns true if the matcher matches *anything*. We need
to check this later, because such matchers are dangerous in loops
that iterate over all parents/siblings since such loops would not
terminate.
With the previous commit all loads of the same icon will share a single
GtkIconInfo, which typicallty means the pixbuf is shared via Info->pixbuf.
However, atm we don't share symbolic icons, which causes these to be re-read
and re-parsed every time. This is especially bad if the icon is used many times
in some form of list. So, we cache the pixbufs and reuse them.
https://bugzilla.gnome.org/show_bug.cgi?id=689081
In order to avoid loading and keeping around the same icon multiple times
we keep a cache of all outstanding GtkIconInfo objects for a given theme.
Additionally we return to the app not the normal pixbuf from the info,
but rather a proxy copy of it sharing the same data, but no extra
reference. This allows us to track when the app is no longer using
the pixbuf, and we can thus ensure that the GtkIconInfo in the cache
stays around for at least as long as the pixbuf is alive.
When the app unrefs the pixbuf we put the Info on a short LRU list
to keep it alive a bit longer, in case the app needs it in a short
while.

This was broken since commit b2aaa94 in 2008. Its commit message
clearly states that the intention was to check for GTK_GRAB,
GTK_UNGRAB and STATE_CHANGED. Lets do that, then.
This was found by Coverity.
... so we don't bump a refcount whenever we get the initial singleton.
We want to use this function instead of
_gtk_css_style_property_get_initial_value() everywhere where we compute
values, because some initial values may depend on settings soon.
Resizes are queued via
gtk_widget_propagate_state()
=> gtk_style_context_set_state()
=> gtk_style_context_queue_invalidate()
=> gtk_style_context_validate()
=> _gtk_widget_style_context_invalidated()
so there's no need to queue an extra one.
Symbolic colors are an implementation detail of the CSS engine and have
been superceded by GtkCssColorValue. We don't want them clobbering the
public API. In particular because the only use I could find in the
public API is people using it to shade colors.
Make _gtk_style_provider_private_get_color() return a GtkCssValue (a
GtkCssColorValue to be exact) instead of GtkSymbolicColor.
With this, the symbolic color usage inside GTK is minimized.
The documentation for gtk_file_chooser_get_filenames() states that the
returned filenames are absolute paths, and uses g_file_get_path() to
construct the filename. The same function is used to construct the
filename in gtk_file_chooser_get_filename(), so it should also return
absolute paths.

When event capturing is enabled, stop propagating scroll events
at insensitive widgets, but don't handle them (don't return TRUE),
so they can bubble up again and reach their handling widgets.
Render a background with gtk_render_background() in draw() instead.

This reverts the size_allocate removal from commit
8449e05865. That code was using
_gtk_window_set_allocation() instead of gtk_widget_set_allocation(). And
that broke glade.
We can set for_size to -1 earlier than we did. Doing so makes sure we
only cache one value (as we should in the first place). In GTK 3.6, this
worked properly, but with Previously, this check was moved further up to
avoid interacting with size groups. But after recent refactorings, size
groups are handled way earlier anyway.
... instead of GtkSizeGroupMode. Orientation is what we're interested in
after all. When we need a GtkSizeGroupMode, we can do the translation
where we need it.

The bitmasks with the 31st, 32nd and 63rd bit set are added. The make up
the largest bitmasks on 32bit/64bit that can be represented without
allocating and the smallest bitmask on 32bit that must be allocated.
With the fix in 77912a65e2, another bug
got visible: booleans are 32 bits, so if the intersection between the 2
bitmasks happened in higher bits, the return value would be truncated to
FALSE.
This actually made slider handles disappear, so it was pretty visible.
If lookup->missing is empty we don't need to continue looking.
We short circuit in several places as this can happen
after iteratively makeign lookup->missing smaller.
We need to use the allocated codepath if *any* argument is
allocated, not if one arg is not allocated.
This bug caused unnecessary calls to _gtk_bitmask_is_allocated,
as well as return completely wrong result if both bitmask are
allocated.
What is this bin doing with all these crazy deltas? Company does:
<Company> that can safely be removed
<Company> in general, code that isn't obvious can either be understood
<Company> with a bit of thinking or it can be removed
<Company> if in doubt, go for the 2nd of those :)
Most GtkBin subclasses override this strange garbage anyway, so it's
not like this code is ever *run*, per se. Just make it proxy directly
to the child, and hope nothing goes wrong.
Implement get_preferred_width, get_preferred_height, and size_allocate.
This allows GtkBin subclasses to be quick and easy, without the
author doing the subclassing to have to do much work.
If the "wider" label is the smaller one, use the wider size for both
cases. This can happen when ellipsizing a single character, which is
often smaller than the ellipsizing glpyph(s).
Functions should not have a space before the opening parenthesis. So
change output like
alpha (@color, 0.5)
to
alpha(@color, 0.5)
and do the same for "shade" and "mix".
Tests have been updated accordingly.
With ellipsizing, the ellipsized text can have a smaller height than the
non-ellipsized text. So the wider text is also higher. Example:
.<big>TEXT</big>
will ellipsize to the small text.

We must make sure to remove the weak pointer when disposing the widget
or when resetting the align widget otherwise glib will try to nullify
invalid memory.
This way we don't need a marker on GtkWidgetParivate that needs to be
unset later, so we have all our data in the same place and can avoid
problems with reentrancy and shenanigans like that.
But the main reason I wrote that is cleaner code.
With this function now available, we can do size computation in 2
ways:
(1) Compute size with size groups
(2) Compute size without size groups
And have (1) use (2) instead of setting flags on widgets. This patch
does exactly that.
With size groups now doing hfw, doing the optimization for CONSTANT_SIZE
was done too early. Size groups need to know that it's a hfw request, so
the other widgets in the size group get the correct behavior.
The label code assumed that Pango treats this as "wrap to as much space
as possible and then ellipsize all the lines", but for Pango, ellipsize
takes precedence over wrap. So do the same thing in GtkLabel.
Also updated is the reftest that checked this behavior.
We compute on-demand for size groups anyway, so we can (in theory, this
patch doesn't do that yet) get around costly cache blowing when
invalidating single widgets of a size group this way.
The current approach of using gtk_widget_get_mapped() is broken:
The usual steps taken when showing a window are:
(1) request the sizes
(2) allocate the sizes
(3) show the window in the allocated size
Showing the window with a random size between steps (1) and (2) would of
course
result in extra work and potential flickering when the widgets get
resized to
their proper sizes.
However, as GtkSizeGroup::ignore-hidden uses gtk_widget_get_mapped() to
determine visibility for a widget, the following will happen:
(1) the widget will request a 0 size
(2) the widget will be allocated a 0 size
(3) the widget will be too small when it is shown
gtk_widget_get_visible() however is set in advance. Note that toggling
visibility also causes a gtk-widget_queue_resize() call already so we
take care of changes in here automatically.
Instead of only checking the ignore_hidden flag when getting the
preferred sizes, respect it already when constructing the list of
widgets. This way, widgets don't queue resizes for groups they're
ignored in anyway.
For loops to loop over lists look nicer and actually do the right thing
with "break" and "continue" statements. So they are vastly preferred to
while loops.
This simplifies code and because sizes are cached by the widgets
themselves, it's not a large performance problem (unless people use huge
amounts of widgets in a single size group, but who does that?
The main problem is that we were emitting the row-deleted signal for the model in the middle
of the process that actually deletes the row from the model (remove the row from the array,
update the model->file_lookup hash table, etc.). In the model's caller, one of the row-deleted
callbacks was requesting an iter, which caused the model to revalidate itself - but it did
this while it was in an inconsistent state. This led to an assertion failure later when the
model resorted itself.
The fix in remove_file() is like this:
* The filteredness/visibility of the deleted node is not updated. The
node will simply be gone; we don't need to update those values at
all.
* We invalidate just the node that is being deleted.
* The model->file_lookup hash table is not completely nuked; instead,
we carefully adjust its indices.
* The row-deleted signal is only emitted at the very end, when
deletion is complete and the model is consistent.

This is a function internal to the file system model; let's not pollute the gtk_tree_path namespace.
Also, make the 'i' variable into 'r' as it refers to a row index, not a file-array index (for

Right now we support loading and recoloring symbolic GFileIcons, but
only if the underlying GFile has a local path. This breaks when the
GFileIcon is loaded from a GResource, which is a reasonable option for an
application that wants to ship a custom symbolic icon.
This patch changes GtkIconInfo to store a GFile together with the file
path, and changes the symbolic icon lookup code to use the GFile URI,
which transparently makes the code work also for GResources.

Move variable initialization outside the first code with side effects.
This allows adding some more early returns, including one for code that
used to trigger g_return_if_fail() in certain corner cases.
Old code tried to use the "background-image" proeprty for setting the
default image background. While this used to work in the early days of
GTK3, today it is grossly misleading as the backgronud image may be
resized, repositioned and semi-translucent which causes very weird
artifacts when rendering.
So we use the background-color only instead.
This way we create one provider per settings object instead of stuffing
it into a global unchanging never-deleting hash table.
Also, we now reload the theme when instructed instead of keeping the old
loaded (and possibly stale) data forever.
https://bugzilla.gnome.org/show_bug.cgi?id=683896
This makes sure the full theme loading logic resides in one function and
isn't scattered around.
As a side-effect, the hash table kept by gtk_css_provider_get_named()
will now be populated with fallback themes. This will not be a problem
after the next commit though.
Split maintaining the global themes hash table and the theme loading
code into two functions.
This also fixes leaking the provider when loading a theme from a builtin
resource.
Themes may want to render handles differently depending on whether
the widget is in selection mode (2 handles enclosing a selection) or
cursor mode (one handle pointing out the insertion cursor).
This improves both interaction and theming, as it allows
arbitrary handle shapes while just being draggable from
the visible areas.
This way themes can set up handles with the hotspot visually
displaced from the horizontal center, as long as the hotspot
lies centered in the image/svg asset.
The check on the handle to be drawn on the mask was based on the yet to
be set priv->windows pointers, pass explicitly the handle position to
have the shape correctly initialized on non-composited environments
The GtkNotebook drag-motion event handler may install a timeout when
hovering over a tab, in order to switch to it.
On the other hand it's desirable for applications to use the empty tab
area as a drop target, so the drag-motion handler returns FALSE
(also in case it installs the switch tab timeout), as explained in
https://bugzilla.gnome.org/show_bug.cgi?id=350665.
Unfortunately, applications can use the tab label widget (or a child
of it) as a different drop target area, and install their own
drag-motion handler there.
In this scenario, the timeout will still be installed by GtkNotebook's
handler, but since it returns FALSE, it will never get the matching
drag-leave event, causing it to trigger also when the mouse pointer
moved elsewhere before it expired.
Fix this by returning TRUE from drag-motion when the event is over a
tab. Note that this makes automatic tab switching not work anymore when
drag and drop is handled in the tab label widget; applications are
expected to also handle tab switching if desired in such a case.

GtkScrollbar used to rely on style-updated being emitted every time
after the widget was created in order to set the right values from its
style properties on GtkRange.
Nowadays we try to be smarter and avoid emitting style-updated at
creation time, so we need to manually initialize the GtkRange values.
This fixes a regression from 35e36b9fe5.

Currently we use gtk_style_context_set_background() when the state flags
change in order to propagate the background color to the overshoot
window, but this is actually only needed because the window doesn't get
expose events, since we always draw a full background in draw().
This also fixes some problems when the GdkWindow of the scrolled
window's child is composited, as seen in oxygen-gtk3.

The implementation of transition for GtkCssShadowValue can return NULL
at least when the two values have a different inset; all other parts of
the GTK/CSS machinery (e.g. GtkCssArrayValue) handle this by returning
NULL too. Instead, GtkCssShadowsValue was returning an invalid value,
where "len" was set, but some values in the array were NULL, which would
lead to a segfault when this value is later evaluated by the compute
function.
Fix this by making GtkCssShadowsValue return NULL if a shadow transition
fails, like GtkCssArrayValue does.
