Hello,

I have a problem to create a dynamic number of QLabel and QLineEdit.

I have build a QList:

Qt Code: 
  1. QList<QLineEdit*> dongleDataLineEdit;
  2. QList<QLabel*> dongleDataLabel;
To copy to clipboard, switch view to plain text mode 

Now, the code to generate my QLabel an QLineEdit.

Qt Code: 
  1. void CMainWindow::setDongleDataField() {
  2. 	for (int i=0; i<plainDongle->DNG_Memmory/4; i++) {
  3. 		dongleDataLabel.append(new QLabel);
  4. 		dongleDataLineEdit.append(new QLineEdit);
  5. 	}
  6.  
  7. 	displayDongleData();
  8. }
  9.  
  10. void CMainWindow::displayDongleData() {
  11. 	QGridLayout *dongleLayout = new QGridLayout;
  12. 	int x = 0;
  13.  
  14. 	for (int i; i<plainDongle->DNG_Memmory/4; i++) {
  15. 		dongleDataLabel[i]->setText(tr("Value "+i));
  16. 		dongleLayout->addWidget(dongleDataLabel[i], x, 0);
  17. 		dongleLayout->addWidget(dongleDataLineEdit[i], x, 1);
  18. 		x++;
  19. 	}
  20. }
To copy to clipboard, switch view to plain text mode 

The problem is, my program does not start, it terminated without any error.

Can someone help me to fix the problem?
