Hello everyone,
I'm just now getting back into GeoExt/Ext JS after being away for ~2-3 years and as a result my skills are somewhat rusty/diminished. I'm having difficulty replicating the autoPan functionality that I was using back then. I tried using the autoPanMapOnSelection option on GeoExt.selection.FeatureModel but this didn't provide the behavior that I was seeking. I had previously used an extension called Ext.ux.map.grid.AutoPanSelectFeatureCtl (I don't remember if I downloaded this or wrote it myself) that extends OpenLayers.Control.SelectFeature and is used for the selectControl option of a GeoExt.grid.FeatureSelectionModel which is then passed as the sm option on a Ext.grid.GridPanel. The functionality provided by AutoPanSelectFeatureCtl is to pan the map only when the selected feature is not within the current extent. I find this much more desirable than the autoPanMapOnSelection behavior of always centering the selection and this is why I'm trying to reproduce this functionality. The bottom line is that I've so far been unable to tweak this to get it to work with GeoExt 2/ExtJS 4. I thought that before I attempt to describe the problems I'm having with this effort that I would run it past the list to see if this is the best strategy for implementing this functionality. I took a look at the code in GeoExt.selection.FeatureModel and was wondering if it might make more sense to extend this and override recenterToSelectionExtent or something else similar to this. Thanks, Gary
