<h1>Xdialog documentation - GTK+ options</h1>
<hr width=30%>
</center>
<p>
<p align="justify">As most GTK+ programs, Xdialog does recognize the GTK+ options. Only a few of them are actually useful though (most of them dealing with GTK+ debugging facilities).
<hr>
<h2>Available GTK+ options (1):</h2>
<pre><ul>
<li> <a href="#DISPLAY">--display</a> <display>
<li> <a href="#CLASS">--name</a> <name>
<li> <a href="#CLASS">--class</a> <class>
<li> <a href="#SYNC">--sync</a>
<li> <a href="#XSHM">--no-xshm</a>
<li> <a href="#FATAL">--g-fatal-warnings</a>
<li> <a href="#MODULE">--gtk-module</a> <module>
<li> <a href="#DEBUG">--gtk-debug</a> <flags>
<li> <a href="#DEBUG">--gtk-no-debug</a> <flags>
<li> <a href="#DEBUG">--gdk-debug</a> <flags>
<li> <a href="#DEBUG">--gdk-no-debug</a> <flags>
</ul>
</pre>
<p align="justify">(1) there may be more or less options available, depending on the GTK+ version, please refer to the GTK+ documentation for options actually available on your system.
<hr>
<ul>
<p><li><a name="DISPLAY"><b>--display</b></a> <display>
<p align="justify">This option allows to specify a X <display> on which the Xdialog window is to be open. This is useful when invoking Xdialog from a script executed by a daemon (e.g.: <b>atd</b> or <b>crond</b>) which does not set the <b>$DISPLAY</b> variable needed by GTK+.
<p><li><a name="CLASS"><b>--name</b></a> <name>
<li><b>--class</b> <class>
<p align="justify">These options allow to set respectively the <name> and the <class> of a GTK+ program, for use by the window manager. Xdialog got its own <a href="common.html#WMCLASS">--wmclass</a> option that sets both its name and class to the same value. You may still want to use these two GTK+ options if you need to set different name and class values.
<p><li><a name="SYNC"><b>--sync</b></a>
<p align="justify">Tells GTK+ (actually the GDK part of GTK+) to make X calls synchronous. This will give very smooth display updates, but very slow as well... No practical use.
<p><li><a name="XSHM"><b>--no-xshm</b></a>
<p align="justify">Prevents GTK+ (actually the GDK part of GTK+) to use the X shared memory extension. In case your X server XSHM is broken (in this case, upgrade !)... No practical use.
<p><li><a name="FATAL"><b>--g-fatal-warnings</b></a>
<p align="justify">Make all GTK+ warnings fatal. Xdialog does not make such warnings to be issued (if it does, it is a bug, please report it !). But you may encounter GTK+ warnings while using Xdialog if your own GTK+ configuration is wrong (e.g. if you are using a GTK+ theme needing for a specific gtk-engine which is actually missing from your system); in this case you will also encounter the same warnings using any other GTK+ application. Using this option will make Xdialog to be killed when a warning is issued rather than reporting this warning on Xdialog stderr (and therefore possibly polluting the strings returned by Xdialog, when the <a href="common.html#OUTPUT">--stderr</a> option is in force). For debugging purpose, no practical use.
<p><li><a name="MODULE"><b>--gtk-module</b></a> <module>
<p align="justify">For additional module loading. Not needed by Xdialog.
<p><li><a name="DEBUG"><b>--gtk-debug</b></a> <flags>
<li><b>--gtk-no-debug</b> <flags>
<li><b>--gdk-debug</b> <flags>
<li><b>--gdk-no-debug</b> <flags>
<p align="justify">Set/unset GTK/GDK debugging <flags>. For debugging purpose only, no practical use.
</ul>
