alternative to QMessageBox

[zlatko]

waitDialog_dlg = new WaitDialog(200, this);

waitDialog_dlg = new WaitDialog(200, this);

To copy to clipboard, switch view to plain text mode

zlatko:
Thanks I have done that bit to instantiate the dialog.
The trouble remains how to call, display and start the dialog and its timer

[wysota]

Please learn it yourself.

I knew zlatko was going to get trouble. Yes, master. I have downloaded the books.

wysota: It is true that I have to learn, and I thank you for your attitude.

For info, your class had a bug, the correct code is :

class WaitDialog : public QDialog {
public:
  WaitDialog(uint interval, QWidget *p=0) : QDialog(p)
  {
    QVBoxLayout *l = new QVBoxLayout(this);
    QLabel *lab = new QLabel("Please wait");
    l->addWidget(lab);
    setLayout(l);
    timer.setSingleShot(true);
    timer.setInterval(interval);
    connect(&timer, SIGNAL(timeout()), this, SLOT(accept()));
  }
 
int exec()     // rather than void
{
  timer.start();
  return QDialog::exec();  // needed return
}
 
private:
  QTimer timer;
};

class WaitDialog : public QDialog {
public:
  WaitDialog(uint interval, QWidget *p=0) : QDialog(p)
  {
    QVBoxLayout *l = new QVBoxLayout(this);
    QLabel *lab = new QLabel("Please wait");
    l->addWidget(lab);
    setLayout(l);
    timer.setSingleShot(true);
    timer.setInterval(interval);
    connect(&timer, SIGNAL(timeout()), this, SLOT(accept()));
  }

int exec()     // rather than void
{
  timer.start();
  return QDialog::exec();  // needed return
}

private:
  QTimer timer;
};

To copy to clipboard, switch view to plain text mode 

Then to call it :

WaitDialog waitDialog_dlg( 2000, this );
if ( waitDialog_dlg.exec() )
{
}

WaitDialog waitDialog_dlg( 2000, this );
if ( waitDialog_dlg.exec() )
{
}

To copy to clipboard, switch view to plain text mode 

I learn slowly, but I am stubborn and I will get there.

A little bug. void should be ok too. It just didn't return a value, which is (by the way) not important here.
