Summary

This chapter has taught you a lot:

• We learned how to create and use the GeoExt.data.store.Features class and configure it with a layer and a map.
• We learned that such stores can be an in place replacement for Ext.data.Store, e.g. to display the contained data in a grid.
• We learned about GeoExt.grid.column.Symbolizer that can be used to render feature symbolizers in grids.
• We also have seen how convenient it is to use event listeners to update the visual representation of your map (the selectionchange listener).

The next and final chapter will briefly introduce you to some other GeoExt components.
