to free or not to free

[masoroso]

Hi all,

I am new to this forum and it looks like a great resource for Qt information. I am used to Delphi so it's Qt as well as C++ I'll have to learn but it sure looks good what Trolltech did!

Now to the question.

I am not sure on the memory stuff. What is automagically destroyed and what is not?

Here is a piece of code of my test project:

VerticalDialog::VerticalDialog(QWidget *parent)
  : QDialog(parent)
{
  VerticalItemModel *vertical = new VerticalItemModel;
  lytMain = new QGridLayout(this);
 
  lytSurface = new QHBoxLayout();
  lytOkCancel = new QHBoxLayout();
  lytOpenSave = new QHBoxLayout();
 
  //table
  tblVertical = new QTableView();
  tblVertical->setAlternatingRowColors(true);
  tblVertical->setModel(vertical);
...

VerticalDialog::VerticalDialog(QWidget *parent)
  : QDialog(parent)
{
  VerticalItemModel *vertical = new VerticalItemModel;
  lytMain = new QGridLayout(this);
  
  lytSurface = new QHBoxLayout();
  lytOkCancel = new QHBoxLayout();
  lytOpenSave = new QHBoxLayout();

  //table
  tblVertical = new QTableView();
  tblVertical->setAlternatingRowColors(true);
  tblVertical->setModel(vertical);
...

To copy to clipboard, switch view to plain text mode 

Do I need to free the memory myself (for example for the QHBoxLayout classes) or does Qt take care of this? I do not assign a parent to them so there is nobody `to take care of them'??

Thanks in advance,
Rob
