<h1>Recoll result list customising exemples</h1>
<p>The Recoll result list is actually made of html text
displayed inside a Qt Widget. In all Recoll versions, you
can specify the format for the list entries: what data is
displayed for each hit document and how. This used to include
"almost full" support for HTML capabilities, with a few
restrictions due to the Qt QTextBrowser object.</p>
<p>As of Recoll 1.17, the result list is by default a WebKit
object (WebKit is the basis for several major browsers), which
yields full CSS and even Javascript support.</p>
<h2>New in Recoll 1.17: the WebKit result list</h2>
<p>For newer Recoll versions, you can specify the
individual result format, as for previous versions. You can
also define code to be included in the HTML
header (ie: CSS or Javascript), using
<tt>Preferences->Query Configuration->Result List->Edit result page html header insert</tt></p>
<p>This, plus the full Javascript and CSS support in WebKit,
open a world of possibilities for result list formatting and
even behaviour.</p>
<p>The examples which follow are probably not generally
very useful but they show the kinds of things you can do, if
you can use Javascript/CSS which is not my case.</p>
<h3>Using the icons as links</h3>
<p>You can now make the list icons links that activate the
preview or open action (or the document url which you can then
drag/drop to other windows). Using images as links did
not work with QTextBrowser.</p>
<h3>Alternating result backgrounds</h3>
<p>Using the following Javascript inside the header will yield
alternating backgrounds for the results:</p>
<pre>
<script type="text/javascript">
function altRows() {
var rows = document.getElementsByClassName("rclresult");
for (i = 0; i < rows.length; i++) {
if (i % 2 == 0) {
rows[i].style.backgroundColor = "#d4e3e5";
}
}
}
window.onload = function() {
altRows();
}
</script>
</pre>
<h3>Zooming the paragraph font size</h3>
<p>If you are using a format with small fonts, it may be useful
to be able to zoom the text when the mouse hovers over it. A
very basic way to do this -<em>with the standard paragraph
format, which is a table</em>- would be to include the following
code in the header:</p>
<pre>
<style type="text/css">
table:hover {font-size: 130%;}
</style>
</pre>
<p>Of course, the selector should be adapted to your own
result format. You should know that every result will be
enclosed by Recoll inside a <tt><div
class="rclresult" rcldocnum="nn"></tt> element.</p>
<h3>Zooming the thumbnails</h3>
<p>Recoll 1.17 and newer will display document
thumbnails instead of the type icon if the thumbnail exists in
the standard Freedesktop location. The icons/thumbnails are
64x64 pixels in size, which is a bit small. The standard
thumbnail files are actually 128x128, which is much more
detailed. Using them statically would consume too much list
space though. Using CSS, you can get them to expand when the
mouse is over them. Recipee:</p>
<blockquote>
<p>Retrieve the CSS code
from <a href="http://randsco.com/_miscPgs/cssZoomPZ3.html">randsco
pure CSS photo-caption zoom</a>, and include it inside the
result list html header by using the "Edit result page html
header insert" from the GUI preferences. Don't forget to
enclose the CSS code between <code><style type="text/css">
</style></code> tags.</p>
<p>Use something like the following result paragraph format
(only the code around the img tag is relevant, the rest can be
what you want):</p>
<pre>
<!--
<table><tr><td>
<div class="PZ3zoom PZ3-l noBdr noCap noLnk" style="width:64px;height:64px;">
<a href="%U"> <img src='%I' width='64'></a>
</div>
</td><td>
%R %S %L <b>%T</b><br>%M %D <i>%U</i> %i<br>%A %K
</td></tr></table>
-->
<table><tr><td>
<div class="PZ3zoom PZ3-l noBdr noCap noLnk" style="width:64px;height:64px;">
<a href="%U"> <img src='%I' width='64'></a>
</div>
</td><td>
%R %S %L &nbsp;&nbsp;<b>%T</b><br>%M&nbsp;%D&nbsp;&nbsp;&nbsp;<i>%U</i>&nbsp;%i<br>%A %K
</td></tr></table>
</pre>
</blockquote>
<div class="PZ3zoom PZ3-r noCap noLnk" style="width:100px;height:40px;">
<a href="resparpics/pz3.png" onclick="return false">
<img src="resparpics/pz3.png" alt="hover zoom" />
</a>
</div>
<p>Et voil�! The icons will grow to their full size when the mouse is
over them.</p>
<h2>Result list paragraph format samples (for all versions)</h2>
<p>The format for paragraphs inside the Recoll GUI result list is
customisable by specifying an html fragment (menu:
<tt>Preferences->Query configuration->User interface->Result paragraph format string</tt>)</p>
<p>Here follow some sample formats. Most of them were contributed by
kind users, and I'll be happy to show their names if they so
wish (abstaining by default).</p>
<h3>Recoll 1.15 default</h3>
<pre>
<!--

<h3>Simple+table</h3>
<p>Same format, but using a table to avoid text flowing into the icon
area.</p>
