GTK caches the settings per display in a static `GArray`, keeping a
reference to the `GdkDisplay` as the key.
However, when closing the display, the corresponding entry is not
removed from the cache in `GtkSettings`.
So when reopening again a `GdkDisplay`, if the new address matches one
of the previously closed display, the cache will return the existing
`GtkSettings` from the cache, which still holds a reference to the old
`GdkScreen` which was freed along the `GdkDisplay`.
To avoid the issue, make sure to remove the `GdkDisplay` and
corresponding `GdkSettings` when closing the `GdkDisplay`.
Also, care must be taken not to recreate the `GdkSettings` and re-add
the `GdkDisplay` to the cache once the display is closed, and make sure
callers of `gtk_settings_get_for_display()` can deal with a returned
value being `NULL` if the display is closed.
Fixes: commit 360a3c1690 - "Use a cheaper way to store settings per
display"

||
* @Short_description: Looking up icons by name
|
||
* @Title: GtkIconTheme
|
||
*
|
||
* #GtkIconTheme provides a facility for looking up icons by name
|
||
* and size. The main reason for using a name rather than simply
|
||
* providing a filename is to allow different icons to be used
|
||
* depending on what “icon theme” is selected
|
||
* by the user. The operation of icon themes on Linux and Unix
|
||
* follows the [Icon Theme Specification](http://www.freedesktop.org/Standards/icon-theme-spec)
|
||
* There is a fallback icon theme, named `hicolor`, where applications
|
||
* should install their icons, but additional icon themes can be installed
|
||
* as operating system vendors and users choose.
|
||
*
|
||
* Named icons are similar to the deprecated [Stock Items][gtkstock],
|
||
* and the distinction between the two may be a bit confusing.
|
||
* A few things to keep in mind:
|
||
*
|
||
* - Stock images usually are used in conjunction with
|
||
* [Stock Items][gtkstock], such as %GTK_STOCK_OK or
|
||
* %GTK_STOCK_OPEN. Named icons are easier to set up and therefore
|
||
* are more useful for new icons that an application wants to
|
||
* add, such as application icons or window icons.
|
||
*
|
||
* - Stock images can only be loaded at the symbolic sizes defined
|
||
* by the #GtkIconSize enumeration, or by custom sizes defined
|
||
* by gtk_icon_size_register(), while named icons are more flexible
|
||
* and any pixel size can be specified.
|
||
*
|
||
* - Because stock images are closely tied to stock items, and thus
|
||
* to actions in the user interface, stock images may come in
|
||
* multiple variants for different widget states or writing
|
||
* directions.
|
||
*
|
||
* A good rule of thumb is that if there is a stock image for what
|
||
* you want to use, use it, otherwise use a named icon. It turns
|
||
* out that internally stock images are generally defined in
|
||
* terms of one or more named icons. (An example of the
|
||
* more than one case is icons that depend on writing direction;
|
||
* %GTK_STOCK_GO_FORWARD uses the two themed icons
|
||
* “gtk-stock-go-forward-ltr” and “gtk-stock-go-forward-rtl”.)
|
||
*
|
||
* In many cases, named themes are used indirectly, via #GtkImage
|
||
* or stock items, rather than directly, but looking up icons
|
||
* directly is also simple. The #GtkIconTheme object acts
|
||
* as a database of all the icons in the current theme. You
|
||
* can create new #GtkIconTheme objects, but it’s much more
|
||
* efficient to use the standard icon theme for the #GdkScreen
|
||
* so that the icon information is shared with other people
|
||
* looking up icons.
