Dear EFL developers, I am currently working on implementation of a clipboard for WebKit-EFL. WebKit?s architecture and test framework requires that system clipboard has to work synchronously. Elementary paste implementation (elm_cnp_selection_get) works asynchronously returning data using paste callback passed as one of elm_cnp_selection_get function. An introduction of nested main loop will help making clipboard in WebKit-EFL work synchronously (more or less similar mechanism is used in GTK+ WebKit port), but the main problem is that elementary clipboard does not return paste callback if selection does not contain any data. Currently when ecore_x_window_prop_property_get function is called asking for AnyProperty it returns 0 if there is no data (number of items stored equals 0). This causes ecore_x_event_handle_selection_notify to exit before SelectionNotify event is added and eventually elementary paste callback is not fired. My patch removes this condition and changes behaviour of this function by allowing to add SelectionNotify event even if data returned is empty.
BR, Michal
