Validate Data in QDialog

[jcraig]

Here's an easy one...I'm running Qt 4.3 on Red Hat. My dialog contains a QTextEdit. When the user presses OK, I need to make sure that the data in the QTextEdit is valid. Since I used Qt Designer to make the dialog, it has a QDialogButtonBox. I have connected the "clicked" signal to a slot which checks the size of the QTextEdit. If the size is adequate, I call "accept()" otherwise the slot just returns. The problem is that the dialog disappears even when accept() is not called. If I use the reject() function, the dialog still disappears.

Below is some code...thanks for any help or ideas.

DataSourceDlg :: DataSourceDlg()
{
   connect(buttonBox, SIGNAL(clicked(QAbstractButton*)), this, SLOT(checkValues(QAbstractButton*)));
}
 
void DataSourceDlg :: checkValues(QAbstractButton* button)
{
 
  if (button->text() == "Cancel")
  {
    accept(); // dismiss dialog with user click on Cancel
  } else {
     if (nodeLineEdit->text() > 3) {
          accept(); // dismiss dialog with valid data 
     }
  }
  return; // invalid data do not dismiss dialog
}

DataSourceDlg :: DataSourceDlg()
{
   connect(buttonBox, SIGNAL(clicked(QAbstractButton*)), this, SLOT(checkValues(QAbstractButton*)));
}

void DataSourceDlg :: checkValues(QAbstractButton* button)
{

  if (button->text() == "Cancel")
  {
    accept(); // dismiss dialog with user click on Cancel
  } else {
     if (nodeLineEdit->text() > 3) {
          accept(); // dismiss dialog with valid data 
     }
  }
  return; // invalid data do not dismiss dialog
}
