Wt

I created a custom derived WTableView with a WStandarditemmodel. I made all items 'drop aware' by enabling drop operations for each item and dropEvent was overridden by a custom method (It is almost the drag and drop treeview example from the documentation page). If a drop is detected dropEvent will be called and Wt::WDropEvent& event has correct information about the drag and drop source. But Wt::WModelIndex& target has no information about the drop item at all. If I go one method call back in the stack frame I see void void WTableView::onDropEvent(int renderedRow, int columnId, std::string sourceId, std::string mimeType, WMouseEvent event) was called. All arguments have useful values except rendered row which is always -1. So no model index can be calculated and I never find out on which item the drop operation took place. If I change to a WTreeView I experience correct behaviour. But in my case I can't change my view to a treeview.
