# Using GTK on Windows {#gtk-windows}
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
More information about GTK on Windows, including detailed build
|
||
|
|
instructions, binary downloads, etc, can be found
|
||
|
|
[online](https://wiki.gnome.org/Projects/GTK/Win32).
|
||
|
|
|
||
|
|
## Windows-specific environment variables {#win32-envar}
|
||
|
|
|
||
|
|
The Win32 GDK backend can be influenced with some additional environment
|
||
|
|
variables.
|
||
|
|
|
||
|
|
### GDK_IGNORE_WINTAB
|
||
|
|
|
||
|
|
If this variable is set, GTK doesn't use the Wintab API for tablet support.
|
||
|

|
||
|
|
|
||
|
|
### GDK_USE_WINTAB
|
||
|
|
|
||
|
|
If this variable is set, GTK uses the Wintab API for tablet support.
|
||
|
|
This is the default.
|
||
|
|
|
||
|
|
## Windows-specific handling of cursors {#win32-cursors}
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
When any other cursor theme is used, GTK will prefer cursors from that theme,
|
||
|
|
falling back to Windows cursors and built-in X cursors.
|
||
|
|
|
||
|
|
Theme can be changed by setting `gtk-cursor-theme-name` GTK setting. Users
|
||
|
|
can override GTK settings in the `settings.ini` file or at runtime in the
|
||
|
|
GTK Inspector.
|
||
|
|
|
||
|
|
Themes are loaded from normal Windows variants of the XDG locations:
|
||
|
|
`%HOME%/icons/THEME/cursors`,
|
||
|
|
`%APPDATA%/icons/THEME/cursors`,
|
||
|
|
`RUNTIME_PREFIX/share/icons/THEME/cursors`
|
||
|
|
|
||
|
|
The `gtk-cursor-theme-size`> setting is ignored, GTK will use
|
||
|
|
the cursor size that Windows tells it to use.
