Add a cache of icon infos that we keep around a little longer, to avoid
loading icons from disk that only exist for a short amount of time (e.g.
during one frame of a cell renderer snapshot).
We make sure recently used items are kept alive by just adding them to
the cache on lookup.
We were allocating IconThemeDir instances and then only later assign a
value to has_icons. In the !has_icons case, we were directly throwing
the IconThemeDir away again.
Delay allocating the IconThemeDirs until we know that it has icons.
This avoids allocating and then de-allocating around 1400 IconThemeDir
instances when opening the widget-factory.
The previous code was hiding the fact that the scan_resources function
almost always did nothing and just used g_resources_enumerate_children()
and then returned FALSE, leaving the caller with cleaning up the already
allocated IconThemeDir. By inlining this, we make sure that calling code
does not even need to allocate the IconThemeDir.
It doesn't really make sense to save the applications and groups in
recent infos as linked lists. We get them from glib as arrays, so we can
as well just save them as such.
Creating a recent manager can be fairly expensive and we won't use it if
the widget is not visible or the recent mode has not been entered. Code
other places can already handle a NULL recent manager, so just create it
when entering the recent mode. And shove 25ms of startup time off the
widget-factory this way.
Delaying this by one frame by putting it in an idle just makes the code
more complex for no gain. The actual slow part is reading the
recently-used.xbel, which happens when creating the recent manager.
We call this function *a lot* it's doing lots of unnecessary work inside
g_str_has_suffix. Get the icon name length only once instead and
open-code the suffix check.
The value returned by gtk_widget_get_settings() depends on the widget's
display, so watch for notify::display instead of using (un)root for
this.
Fixes the warnings seen when show a file chooser from the inspector.
This code is better because:
1) The coordinates translations are actually correct and not sometimes
wrong like before
2) We clip widgets that have overflow set
3) We honor the widget's transform
4) It is less code
The scale might be allocated at a height greater than requested, and in
that case y=0 is just too far away. Allocate the value directly next to
the slider instead.
It's almost never useful to have a bitmask here, since it's only used
for the intersection case in gtk_css_style_provider_lookup. However,
even if that returns true, we still need to check every single style
property for being set again in the look afterwards.
Just remove the bitmask.
The slowest part of that fuction is the type check for
GtkCssShorthandProperty. Subproperties of shorthand properties never
refer to more shorthand properties however, so we don't want to have the
type check for those.
When a popover menu has an open submenu,
delay activating another item until after
the pointer is stationary for a little
while. This avoids the need for precise
horizontal motion when moving towards the
submenu.
When GtkApplication starts listening to the screensaver's D-Bus
status, the screensaver-active property is not initialised and
applications making use of the property are out of sync until the
first state change. Any application starting when the screensaver is
active will think it's inactive.
To fix this, we set the property when we first start monitoring the
screensaver.
This tries to estimate the number of visible rows in a textview based on
the default text size and then tunes the GtkTextLineDisplayCache to keep
3*n_rows entries in the cache.
This was found imperically to be near the right cache size. In most cases,
this is less than the number of items we cache now. However, in some cases,
such as the "overview map" from GtkSourceView, it allows us to reach a
higher value such as 1000+. This is needed to keep scrolling smooth on
the larger view sizes.
With this patch, a HiDPI system with a GtkSourceView and GtkSourceMap
from the GTK 4 port can perform smooth scrolling simultaneously.
We do not need to create a GtkTextIter to perform the comparison here as
that will require a number of validation steps that are extra work
compared to just discovering the GtkTextLine number directly.
We're mainly using this for icons that will never change contents or
size, and we're using a GtkScaler per such icon when on a hidpi setup,
so just avoid the two signal connections per icon.
Because otherwise when the file list is sorted "by name"
and the new name causes the file to be re-sorted to another
row, the selection stays in the old row which is now
occupied by a different file.
Fixed by keeping track of the renamed file and revealing
it in the "row-changed" signal handler, which gets emitted
after a file is renamed.
Fixes issue #948
This CSS snippet was supposed to only recolor the popover arrow but
ended up also recoloring the > arrow on modelbuttons that show a
submenu. Make the selector more specific.
The cairo pattern in use was simple enough, so just use a 2×1 or 1×2
texture to draw horizontal and vertical grid lines. This avoids a bunch
of cairo nodes (that can't be cached by the renderers).
Just queue_resize()ing the range itself doesn't work as it will just
re-allocate all the child widgets (i.e. just the trough) to its old
position and size.
We want to ensure all of the display cache entries are released in the
normal fashion before releasing the structures so that we can maintain
the invariant that cache_iter will always exist while in the cache.
This is happening for me when snapshotting small thumbnails in the file
chooser. The GtkScaler will scale the 1px height/width by 2, resulting
in nothing being drawn at all.
There is no reason for this to be a signal, since multiple handlers
don't make sense anyway. It was also broken because the scale needs to
know when a signal handler is added so it can update the value
representation.
Replace the signal with a set_format_value_func function which allows us
to do that.
Fixes#113
When loading a SVG icon from a gresource file only containing SVG icons,
but without having a SVG loader available in gdk-pixbuf, we would crash
when trying to eventually load the resource. Fix this by gracefully
handling this by simply failing to load the icon, while the first time
it happens, log a warning.
Fixes: https://gitlab.gnome.org/GNOME/gtk/issues/2084
- use even sides for the titlebuttons so the result is a circle and not an ellipse
- add maximum border radius
- set min width/height to 0
- adjust margin and padding to match the previous look
