Just launch QMessageBox and then continue with following code?

You won't have a memory leak if you set the attribute such that the object is deleted once the messagebox is closed. You can do this by setting:

msgBox->setAttribute(Qt::WA_DeleteOnClose);

msgBox->setAttribute(Qt::WA_DeleteOnClose);

To copy to clipboard, switch view to plain text mode

Hey, thank you all. It finally worked. This is what I did:

QMessageBox *msgBox1 = new QMessageBox;
//here button declarations
 msgBox1->setWindowModality(Qt::NonModal);
    QCoreApplication::processEvents();
    msgBox1->show();
    QCoreApplication::processEvents();

QMessageBox *msgBox1 = new QMessageBox;
//here button declarations
 msgBox1->setWindowModality(Qt::NonModal);
    QCoreApplication::processEvents();
    msgBox1->show();
    QCoreApplication::processEvents();

To copy to clipboard, switch view to plain text mode 

Thank you all
On last problem:
After this first "Please Wait" button, I want to close it and open the next one, which informs the user about update or not. The thing is, that when I call
if(msgbox->isEnabled())
msgbox->close();
it just deletes all the "widgets" of the msgBox and it let it empty. What should I call?

EDIT:
I was wrong, the msgBox when is shown IS EMPTY (nothing is shown, even if I have call setText() )
When another button is shown and I call msgbox->close(), the text is shown for 0.00001 secs and then it disappears, as it should...
What's wrong?

Well, I've placed everywhere qApp->processEvents(); and I have
msgBox1->setAttribute(Qt::WA_DeleteOnClose);
msgBox1->setWindowModality(Qt::NonModal);

but now, sometimes it does show up normally, sometimes it is too slow and it only updates when it is to close to show the next messagebox...Quite weird.... ANy other who want to help me a bit? I think I am close....
