children of a QFrame: possible to delete?

[vonCZ]

I have a function:

mkPan();

that makes all the Information panels for my Qt Application. The panels are QFrames with one or more QLabels made up of QStrings and/or QPixmaps. I define the components of a particular panel in my .h file like so:

QFrame    *panFra1;
QLabel      *panLab1;
QString     *panStr1;

QFrame    *panFra1;
QLabel      *panLab1;
QString     *panStr1;

To copy to clipboard, switch view to plain text mode 

I'd like to free-up / clean-up memory by deleting everything but the QFrame after it's been made. I've noticed that I can do this with QStrings: after defining a QLabel and setTexting it with a QString, I can then delete the QString. Presumably the QString is rasterized on the QLabel, and there's thus no longer any need to keep it (the QString) around. (And I can therefore simply create QString's on the stack within the mkPan() function and don't need to declare pointers to them in the .h file.) If I try the same with the QLabels, however: they don't show up on the QFrame. Is there a way to 'rasterize' the QLabels onto the QFrame so I don't need to keep them around? ...or is this even something I should worry about.

One last thing: I'd want to stop declaring the QLabel's in the .h file and simply declare them in the mkPan() function as needed. Is this OK:

mkPan()
{
  if(panType == 7)
  {
    for(int a=0; a<numberOfLabelsThisPanel; a++)
    {
      QLabel *tempLab = new QLabel;
      tempLab->setText(panStr);
      //  etc...
      //  delete tempLab;  //  this I cannot do
    }
  }
}

mkPan()
{
  if(panType == 7)
  {
    for(int a=0; a<numberOfLabelsThisPanel; a++)
    {
      QLabel *tempLab = new QLabel;
      tempLab->setText(panStr);
      //  etc...
      //  delete tempLab;  //  this I cannot do
    }
  }
}

To copy to clipboard, switch view to plain text mode 

...i've left some stuff out here, including methods for getting the appropriate QString value, but the crux of my question is: can I declare "QLabel *tempLab" over and over again... or do they have to be unique names?
