QTreeView Headers not displaying properley.

[jigglyslime]

Hey guys,

Ok so my problem here is that, i have a tree view in my program but it won't show the headers i set in the model.

Here is the model code whihc sets the headers:

QStringList Headers;
    Headers.append(QString("Name"));
    Headers.append(QString("Progress"));
    Headers.append(QString("Rating"));
    Headers.append(QString("Type"));
    //Headers << "Name" << "Progress" << "Rating" << "Type";
 
    DataModel->setHorizontalHeaderLabels(Headers);

QStringList Headers;
    Headers.append(QString("Name"));
    Headers.append(QString("Progress"));
    Headers.append(QString("Rating"));
    Headers.append(QString("Type"));
    //Headers << "Name" << "Progress" << "Rating" << "Type";

    DataModel->setHorizontalHeaderLabels(Headers);

To copy to clipboard, switch view to plain text mode 

and here is what i get when i run the program:Capture.PNG

any ideas why?

Also for some reason i cannot resize the columns programatically aswell
