[SOLVED] Qt::Orientation problem

Here is a snippit of the code I am trying to write, which creates a view of a table, displays it, and then prints it. The display works great, the data prints great, but I haven't been able to get the column headers to print yet.

QSqlQueryModel *BRmodel = new QSqlQueryModel;
BRmodel->setQuery(dbrStr);
if (BRmodel->rowCount() > 0 ){
    QTableView *view = new QTableView;
   view->setModel(BRmodel);
    view->show();
    // add code to create html page from BRmodel row and column data
    QPrinter *printer = new QPrinter;
    QPainter p(printer);
    QFont Courier10("Courier",10);
    p.setFont(Courier10);
    int x_pos = 20;
    int y_pos = 20;
    QHeaderView *viewhhdr = view->horizontalHeader();		
    QString hdrtxt;		
    for (int col = 0; col < viewhhdr->count(); ++col){
	hdrtxt += viewhhdr->model()->headerData(col,Qt::Orientation::Horizontal,Qt::DisplayRole);
....
}


The problem is that it produces an error:

 error C2039: 'Horizontal' : is not a member of 'Qt::Orientation'
...
...
 error C2065: 'Horizontal' : undeclared identifier

but, the API gives:

QAbstractItemModel::headerData ( int section, Qt::Orientation orientation, int role = Qt::DisplayRole )

I have tried just "Qt::Horizontal" and it doesn't work either. I have also tried to recast several times and ways.
What's the magic formula?

Try:

Source code

viewhhdr->model()->headerData(col,Qt::Horizontal,Qt::DisplayRole);

Thanks for the reply, but in my last sentence I indicated that I had already tried your solution, "Qt:Horizonal", before I posted.

RE: Qt::Orientation problem

Are you using Qt 4? In Qt 4 it's really Qt::Horizontal and it works since it's used in Qt itself.

Sorry, I haven't noticed it. Could you post the error message you get when you use "Qt::Horizontal"?

[SOLVED] Qt::Orientation problem

Taking a weekend break away from a problem can let you take an entirely fresh view of it. When I got to work this morning and saw your request to show the error msg for "Qt::Horizontal" try, as shown in the code snippet below,

Source code

 
1
2
3

hdrtxt += viewhhdr->model()->headerData(col,Qt::Horizontal,Qt::DisplayRole);

which gives:

haptest.cpp(1266) : error C2679: binary '+=' : no operator found which takes a r
ight-hand operand of type 'QVariant' (or there is no acceptable conversion)

the problem stood out immediately: " 'binary '+=' no operator ...", not the orientation problem I had narrow mindedly focused on last Friday.

I modified the code to:

Source code

 
1

hdrtxt += viewhhdr->model()->headerData(col,Qt::Horizontal,Qt::DisplayRole).toString();

and it works now.
Thanks jacek!
