<p>Hi Silvain,</p>
<p>Hm - this will require a "Python action".</p>
<p>Because with a generic action you could do something like:</p>
<p>length(make_line($geometry,make_point(@click_x,@click_y)))</p>
<p>using a QGIS expression, but there are two problems:</p>
<p>- you can only get @click_x and @click_y if you click on the feature; but since it is a point feature you cannot click outside the tolerance of this point in order to receive the coordinates</p>
<p>- generic actions do not allow updates of data</p>
<p>So you'd have to use a Python action. If you Google for QGIS Python actions, you should get some ideas how it works.</p>
<p>Andreas</p>
