Salve.
Una nuova aggiunta a QGIS: le informazioni sui layer vettoriali possono
ora essere configurate e mostrare pagine HTML, incluse immagini ecc.
Saluti.

New fresh QGIS feature! So fresh in fact you can still smell the wet paint
:)

QGIS (development build) can now
(https://github.com/qgis/Quantum-GIS/commit/8aa160bcb3548a881248c7d46d92c4f2e12ffc02)
 display map tips using HTML (a subset
(http://doc.qt.nokia.com/4.7-snapshot/richtext-html-subset.html)  anyway).

To enable the new map tips: Open the Layer Properties dialog for a layer
and select the Display tab

In action

Notice how we can also use a QGIS expression. Anything inside [% %] will
be evaluated and replaced with the value in real-time. We can even use a
CASE statement. Pretty cool!

And the result when hovering over a feature

Hold on. Pause the track! We can even use some CSS to make it more fancy.

<style>
h1 {color:red;}
p.question {color:blue;}
</style>
<h1> [% "NAME" %] </h1>
<br>
<img src="[% "image" %]" />
<br>
<p class="question">Is this place a country?</p>
<br>
[% CASE WHEN "TYPE" = 'Country' THEN 'Yes' ELSE 'No. It is a ' || "TYPE"
END %]

Happy Mapping :)
