<title>Windows-specific commandline options</title>

<para>
The Windows GDK backend can be influenced with some
additional command line arguments.
</para>

<formalpara>
<title><systemitem>--sync</systemitem></title>

<para>
Don't batch GDI requests. This is a useful option for 
debugging, but it will slow down the performance considerably.
</para>
</formalpara>

<formalpara>
<title><systemitem>--no-wintab</systemitem>, 
       <systemitem>--ignore-wintab</systemitem></title>

<para>
Don't use the Wintab API for tablet support. This is the default.
</para>
</formalpara>

<formalpara>
<title><systemitem>--use-wintab</systemitem></title>

<para>
Use the Wintab API for tablet support, if GTK+ has been compiled 
with the <option>--with-wintab</option> option.
</para>
</formalpara>

<formalpara>
<title><systemitem>--max-colors <replaceable>number</replaceable></systemitem></title>

<para>
In 256 color mode, restrict the size of the color palette to 
the specified number of colors.

<title>Windows-specific environment variables</title>

<para>
The Win32 GDK backend can be influenced with some
additional environment variables.
</para>

<formalpara>
<title><envar>GDK_IGNORE_WINTAB</envar></title>

<para>
If this variable is set, GTK+ doesn't use 
the Wintab API for tablet support. This is the default.
</para>

<formalpara>
<title><envar>GDK_USE_WINTAB</envar></title>

<para>
If this variable is set, GTK+ uses the Wintab API for 
tablet support, if GTK+ has been compiled with the 
<option>--with-wintab</option> option.
</para>
</formalpara>

<formalpara>
<title><envar>GDK_WIN32_MAX_COLORS</envar></title>

<para>
Specifies the size of the color palette used
in 256 color mode.
