Saving/restoring QTreeView state (Qt 4.3 )
Message 1 in thread
Hi people,
In my application i need to save and restore a QTreeView whole state,
for instance when the project is saved then loaded, QTreeView's columns
widths, expanded/collapsed indexes, selected indexes, hidden
rows/columns etc ... must be restored.
Basically it means i will have to loop on each column, save its width,
then each row, save its height, then all indexes, etc ... which is not a
really hard, but definitely a boring job.
Does anyone know a better way to handle the views' state save and restore ?
Thanks for any suggestions,
Regards,
Michael

At least for the header (columns) you can use the new
saveState()/restoreState() function that was added in 4.3.
