Thank you.
Is it possible to have just the CSS config for this progressBarWidget ?
Tips : for my Show/Hide question, i find this solution :
JSHideWidgetInt:string= 'reconfigure='
+'function reconfigure(sender, store, columns, oldStore, the, eOpts) {'
+' var widgetColIndx = %d;'
+' columns[widgetColIndx].onWidgetAttach = function(column, widget, record) {'
+' if (record.data[%d] == %d) {'
+' widget.hide();'
+' } else {'
+' widget.show();'
+' }'
+' };'
+'}';
