|
The Windows port of GTK is an implementation of GDK (and therefore GTK)
|
|
on top of the Win32 API. When compiling GTK on Windows, this backend is
|
|
the default.

<title>Windows-specific handling of cursors</title>

<para>
|
|
By default the "system" cursor theme is used. This makes GTK prefer cursors
|
|
that Windows currently uses, falling back to Adwaita cursors and (as the last
|
|
resort) built-in X cursors.
|
|
</para>
|
|
<para>
|
|
When any other cursor theme is used, GTK will prefer cursors from that theme,
|
|
falling back to Windows cursors and built-in X cursors.
|
|
</para>
|
|
<para>
|
|
Theme can be changed by setting <literal>gtk-cursor-theme-name</literal> GTK setting. Users can override GTK settings in the <filename>settings.ini</filename> file or at runtime in the GTK Inspector.

Themes are loaded from normal Windows variants of the XDG locations:

<filename>RUNTIME_PREFIX/share/icons/THEME/cursors</filename>.

<para>

The <literal>gtk-cursor-theme-size</literal> setting is ignored, GTK will use the cursor size that Windows tells it to use.
