Hi:
I have a situation where I need to verify data before allowing a row change in
a GtkTreeView. Essentially:
1. User requests a row change through a keyboard or a mouse;
2. Check if data in the current row has been edited without be saved, or even
is complete
and valid, and prompt the user appropriately;
3. Depending on user request, I may need to veto the row change request (aka
cancel)
What's the best practice?
A possible way is use "cursor-changed" signal
1. always remember the current row (possibly by store a GtkTreeIter)
2. in the cursor-changed signal handler, check if on the same row and go back
to original row by way of
stored GtkTreeIter if necessary.
Is there a better way? Tell me how you would approach this please.
Thanks,
Lance
