[Qgis-developer] undisplayed elements are selected

[Andreas Neumann]

 hm - I agree with Denis. Features invisible because of scale ranges 
 should not be selectable and should not react to map tips.

 In QGIS Server we filtered the invisible features away in 
 GetFeatureInfo requests. The same should be done for selecting features 
 in QGIS desktop and for the map tips. The rule-based renderer V2 offers 
 a method called willRenderFeature() (see 
 http://doc.qgis.org/api/classQgsRuleBasedRendererV2.html#b514bc63bd9e744faca24236a89b7e4d) 
 that could be used to see if such a feature is displayed or not. But 
 the method says that it has to be called between startRender() and 
 stopRender() calls - so I don't know if it would work for 
 querying/selection features?

 Any thoughts?
