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
GtkFileChooserNativeWin32 is created and shown on a secondary thread.
This thread initializes COM support with CoInitializeEx but does not
finalize it, so we have a leak. Fix that by calling CoUninitialize()
before thread terminates.
See Merge Request !1043
Although slightly less efficient, keeping the order in the choices
list makes it easier for GtkFileChooserNative implementations to
add widgets in the order specified by the application.

When processing the list of icons for a window to add them to
_NET_WM_ICON gdk_x11_surface_set_icon_list only adds as many
icon sizes as will fit within X protocol limits.
It achieves this by keeping a running total of the number of
bytes taken up by icons already processed and bails as soon
as it goes over the limit.
The problem is, one 512x512 icon is already over the limit,
and so no icons will get added at all if the first icon in
list is 512x512.
Indeed, the code seems to assume the list is sorted from smallest
icon to biggest icon.
This commit changes the caller to sort the list.
This adds a GtkTextLineDisplayCache which can be used to cache a number
of GtkTextLineDisplay (and thus, PangoLayout) while displaying a view.
It uses a GSequence to track the position of the GtkTextLineDisplay
relative to each other, a MRU to cull the least recently used display,
and and a direct hashtable to lookup display by GtkTextLine.
We only cache lines that are to be displayed (!size_only). We may want to
either create a second collection of "size_only" lines to speed that up,
or determine that it is unnecessary (which is likely the case).
Don't insert text attributes if the font, or scale
or fallback did not actually change. This helps
Pango avoid excessive item breaks, which in turn
helps shaping to work across things like color
changes.

This makes GtkTextLineDisplay use GRcBox instead of g_slice_*
directly. By using reference counting for this structure, we
can ensure that we hold an extra ref for one_display_cache as
well as caching additional GtkTextLineDisplay for the visible
range in the future.
Update the cached text style when a css change affects
content or background. This fixes text views drawing
black-on-dark when switching to the dark theme.
This removes the use of GtkTextDisplay (a PangoRenderer) to use
the GskPangoRender which generates render nodes. Part of this means
improving the GskPangoRenderer to support the necessary features for
displaying a GtkTextView.
Primarily, this is a merging of GtkTextDisplay features into
GskPangoRender. Additionally, GtkTextDisplay was removed to allow for
gtk_text_layout_snapshot() to be implemented elsewhere.
This was previously removed because it changes the minimum and natural
size of the entry when the icons are shown/hidden at runtime. Just not
measuring them does not work however, so reintroduce this.
This reverts commit 2ed533c3e1.
This also made the filechooser dialog not save the window size anymore,
which does not depend on the gtk_window_get_position() removal.
... when going between recent and browse. It just looks weird to have
this transition while the treeview model is just cleared/repopulated
without any transition.
GMountOperation now supports options to unlock TCRYPT volumes. This
patch sets these options if they are returned by AskPassword() of a
GtkMountOperationHandlerProxy.
