<br>
After all my filter is there for a reason - I want them to be invisible and therefore I don't want them to be selectable if they are invisible. QGIS server with GetFeatureInfo behaves like this and I think it is logical.<br>
<br>
It even gets more complicated if you digitize and have snapping settings on a rule-based layer. Think about it - you digitize and suddenly it snaps to some invisible feature - it would be a usability nightmare ...<br>

some thoughts (unordered):<br>
<br>
A) thinking from the table side I can always select any feature there<br>
regardless if it is currently visible or not. When I zoom to the<br>
selection then I am responsible that all features are visible in order<br>
to see my selection. So the current behaviour is just the other way<br>
round. If I want to exclude features I have to define a query on the<br>
layer filtering out unwanted features.<br>
<br>
B) map visibility can be controlled by three ways:<br>
1) visibility of the layer on/off => features are not selectable in map<br>
2) scale-based visibility of the whole layer => features get<br>
selected, even when not visible<br>
3) rule based style with scale based visibility for rules (Denis'<br>
case) => features get selected, even when not visible<br>
To me case 1 is expected behaviour, cases 2 and 3 are not (although<br>
not too unexpected when considering thought A), but hard to explain to<br>
a user)<br>
<br>
- possible solution to accompany A) and B): show all selected<br>
features in selection color regardless of their individual scale-based<br>
visibility. No idea if that is feasible.<br>

hm - I agree with Denis. Features invisible because of scale ranges<br>
should not be selectable and should not react to map tips.<br>
<br>
In QGIS Server we filtered the invisible features away in GetFeatureInfo<br>
requests. The same should be done for selecting features in QGIS desktop<br>
and for the map tips. The rule-based renderer V2 offers a method called<br>
willRenderFeature() (see<br>
<br>
<a href="http://doc.qgis.org/api/classQgsRuleBasedRendererV2.html#b514bc63bd9e744faca24236a89b7e4d" target="_blank">http://doc.qgis.org/api/<u></u>classQgsRuleBasedRendererV2.<u></u>html#<u></u>b514bc63bd9e744faca24236a89b7e<u></u>4d</a>)<br>
that could be used to see if such a feature is displayed or not. But the<br>
method says that it has to be called between startRender() and<br>
stopRender() calls - so I don't know if it would work for<br>
querying/selection features?<br>
<br>
Any thoughts?<br>

I would say this could be an expected behaviour as styling is only a<br>
visual thing and doesn't affect the data....maybe.<br>

Subject: [Qgis-developer] undisplayed elements are selected<br>
Hi all,<br>
<br>
When using the rules style for a layer and defining a scale range, if<br>
you select by rectangle on the map, everything is selected including<br>
undisplayed features.<br>
<br>
Is there already an issue opened, I searched without any result.<br>
<br>
Greetings,<br>
<br>
Denis<br>
