c++ - QTableView column width -

i'm struggling set column width manually in qtableview. why doesn't piece of code work?

tabb = new qtableview; tabb->resizecolumnstocontents(); (int col=0; col<20; col++) { tabb->setcolumnwidth(col,80); }

if omit tabb->resizecolumnstocontents(); still doesn't work.

you should set model first , after able alter columnwidth:

tabb = new qtableview; tabb->setmodel(somemodel); (int col=0; col<20; col++) { tabb->setcolumnwidth(col,80); }
