I refresh a WTreeTable the server push way: steps to take into account: 1. this->enableUpdates(true); on your WApplication (I just put that right after creating the WApplication) 2. in your non-wt thread: do a WServer post with a callback method that will fill the data eg. server_.post(session_id_, boost::bind(&some_page::refresh_data, this)); 3. Wt will run the refresh_data callback function when it is ready (so you don't have to lock). But make sure that at the end of the method you put WApplication::instance()->triggerUpdate(); This indicates that Wt has to check for changes and apply them client side.
That should do the trick. Regards, Rob.

For other component getUpdateLock triggerUpdate flow works ,but not for WTableView. If I reload WAbstractItemModel on next scroll event table data is re-rendered correctly ,but do not want to simulate scroll event as an workaround. Seems computeRenderedArea() and scheduleRerender(NeedAdjustViewPort) function do the magic but they are declared private. Probably I missed something but I've ran out of ideas. regards, Zhivko ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
