[Qt-interest] Colum Names form QTreeView

[Rob Simmermon]

I have figured out how to get the column headings, but now when I call  
"sizeHintForCOlumn" my program crashes.

here's my code:

     for(columnCounter=0;columnCounter<columnCount;columnCounter++)
     {
         // get column header and add to end of current line
          
lineToWrite.insert(insertPoint,tvTreeView->model()->headerData(columnCounter,  
Qt::Horizontal).toString());
          
insertPoint+=tvTreeView->header()->sizeHintForColumn(columnCounter) + 2;
     }


It crashes on the last line of the loop on the very first iteration.
