Using GTK+ on WindowsUsing GTK+ on Windows — Windows-specific aspects of using GTK+ |
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.
The Windows GDK backend can be influenced with some additional command line arguments.
--sync.
Don't batch GDI requests. This might be a marginally useful option for
debugging.
--no-wintab,
--ignore-wintab.
Don't use the Wintab API for tablet support.
--use-wintab.
Use the Wintab API for tablet support. This is the default.
--max-colors .
In 256 color mode, restrict the size of the color palette to
the specified number of colors. This option is obsolete.
number
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.
GDK_WIN32_MAX_COLORS.
Specifies the size of the color palette used
in 256 color mode.
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.
More information about GTK+ on Windows, including detailed build instructions, binary downloads, etc, can be found online.
