Setting Windows Flag on a QDialog hides the form

I currently have a form that inherits from QDialog. Now in order to hide the ? icon on the form I am doing something like this in the constructor.

foo::foo(QWidget *parent): QDialog(parent)
{
    .....
    this->setWindowFlags(Qt::WindowTitleHint);
}

The problem with this is that the Dialog does not show up. If I ommit the flags line it shows up. I am using QT 5.1.1

To answer the question, here the solution:

setWindowFlags(windowFlags() & ~Qt::WindowContextHelpButtonHint);

If you want the minimize and maximize options, do the following:

setWindowFlags(windowFlags() & ~Qt::WindowContextHelpButtonHint) | Qt::WindowMaximizeButtonHint | Qt::WindowMinimizeButtonHint);

To get this to work on linux I had to use both options described above:

setFixedSize(width(), height());
setWindowFlags(Qt::Drawer);

The result is a dialog with only a close button.

Eventually you want to call

this->setWindowFlags(this->windowFlags() | Qt::WindowTitleHint);
