<p>The <a class="link" href="LatexilaSynctex.html" title="LatexilaSynctex"><span class="type">LatexilaSynctex</span></a> class (a singleton) implements the support of SyncTeX
between LaTeXila and the Evince PDF viewer. It is used to switch between the
source file(s) and the PDF, at the same position in the document. It is called
the forward search: source file -> PDF. And backward search: PDF -> source
file.</p>
<p>D-Bus is used to communicate between LaTeXila and Evince. The implementation
uses the asynchronous gdbus generated functions.</p>
<p>For the position, only the line is used, not the column. The column is a bit
buggy.</p>

<p>Does a forward search, i.e. switch from the *.tex file to the PDF file at the
same position as the cursor position in <em class="parameter"><code>buffer</code></em>
.</p>
<p>A correct <em class="parameter"><code>timestamp</code></em>
of the event is important. If <a href="http://developer.gnome.org/gdk2/gdk3-Events.html#GDK-CURRENT-TIME:CAPS"><code class="literal">GDK_CURRENT_TIME</code></a> is used
instead, Evince is sometimes not shown directly, a notification appears
instead saying that the "Document Viewer [...] is ready". It's more
convenient if the Evince window is presented directly, which should work if
the correct <em class="parameter"><code>timestamp</code></em>
is provided.</p>
