<chapter id="Introduction">
<title>What is KDebugDialog?</title>

<para>It is a dialog box for managing diagnostic messages at runtime.
</para>

<para>If you simply start <command>kdebugdialog</command>, you will
see a list of <quote>areas</quote>, that can be disabled or enabled. A
<function>kdDebug(area)</function> call in the code will show
something in the debug output only if the area is enabled.</para>

<note><para>Note that kdWarning, kdError and kdFatal always appear,
they are NOT controlled by this setting.  </para></note>

<variablelist>
<varlistentry>
<term><guilabel>Area</guilabel></term>
<listitem>
<para>The areas which should only be output. Every message
that is not mentioned here will simply not be output (unless
this field remains empty, which is the default, and means that all
messages should be output). You can enter several areas
separated by commas here, and you can also use area ranges with
the syntax start-end. Thus a valid entry could be:
117,214-289,356-359,221. Do not use whitespaces.</para>
</listitem>
</varlistentry>
</variablelist>

<para>If you start <command>kdebugdialog</command>
<option>--fullmode</option>, then for every severity level you can
define separately what should be done with the diagnostic messages of
that level, and the same for each debug area.</para>

<para>In full mode, first you should select the debug area you are
interested in from the drop down list at the top.</para>

<para>You may independently set the output for various types of
messages:</para>

<itemizedlist>
<listitem><para><guilabel>Information</guilabel></para></listitem>
<listitem><para><guilabel>Warning</guilabel></para></listitem>
<listitem><para><guilabel>Error</guilabel></para></listitem>
<listitem><para><guilabel>Fatal Error</guilabel></para></listitem>
</itemizedlist>

<para>For each of these types, you can set the following:</para>

<variablelist>
<varlistentry>
<term><guilabel>Output to:</guilabel></term>
<listitem>
<para>In this Combobox, you can choose where the messages
should be output. The choices are: <quote>File</quote>, <quote>Message
Box</quote>, <quote>Shell</quote> (meaning stderr) and
<quote>Syslog</quote>. Please do not direct fatal messages to syslog
unless you are the system administrator yourself. The default is
<quote>Message Box</quote>.</para> 
</listitem>
</varlistentry>

<varlistentry>
<term><guilabel>Filename:</guilabel></term>
<listitem><para>This is only enabled when you have chosen
<quote>File</quote> as the output and provides the name of that file
(which is interpreted as relative to the current folder). The
default is <filename>kdebug.dbg</filename>.</para>
</listitem>
</varlistentry>
</variablelist>

<para>Apart from this, you can also tick the checkbox <guilabel>Abort
on fatal errors</guilabel>. In this case, if a diagnostic message with
the severity level <computeroutput>KDEBUG_FATAL</computeroutput> is
output, the application aborts with a SIGABRT after outputting the
message.</para>

<para>When you close the dialog by pressing <guibutton>OK</guibutton>,
your entries apply immediately and are saved in
<filename>kdebugrc</filename>. When you press
<guibutton>Cancel</guibutton>, your entries are discarded and the old
ones are restored.</para>
