Refreshing Models - cannot encode a raw index to raw again
Added by Mark Petryk over 7 years ago
I am trying to get my table-views to refresh properly, and periodically I will get exceptions thrown with things like "Geometry Inconsistent" and things like that. These errors are random and they appear to occur when 'scrolling' through a sql-model table-view.
I've looked at the Git model example, and it talks about using "layoutAboutToBeChanged" so I applied that to my table view and I've started to see this message:
The signal is emitted on at or about line 855, when the model is re-queried...
src/ccb/projectcbrv.h:855(void CCB::ReportView<C>::setQuery(const string&) [with C = CCB::ProjectCB; std::__cxx11::string = std::__cxx11::basic_string<char>])

What is the significance of these messages and should I worry about them?
