Examples of com.extjs.gxt.ui.client.data.ModelData

com.extjs.gxt.ui.client.data.ModelData
Primary interface for GXT model objects without support events. Models support a form of "introspection" as property names and values can be retrieved at runtime.
For models with event support see {@link Model}.
For a default implementation see {@link BaseModelData}.

      for (int i = firstRow; i <= lastRow; i++) {
        ModelData m = store.getAt(i);
        getRow(i).setAttribute("aria-level", "" + treeStore.getDepth(m));
