Hello All

I have created a QLineEdit delegate to add it to TreeView, the source code is done using the spinbox delegate example.
What I want is to get the value of that line edit box. I cant seem to get the correct value. I always get the one before the last value.

My questions is HOW to update the control so I can get the current value that the user presses Enter?

Below is the class for the LineEditDelegate, and also for the getValue slot in Mycalss


Qt Code: 
  1. LineEditDelegate::LineEditDelegate(QObject *parent, Myclass* mc)
  2.         : QItemDelegate(parent), m_mc(mc)
  3. {
  4. }
  5.  
  6. QWidget *LineEditDelegate::createEditor(QWidget *parent,
  7.                                         const QStyleOptionViewItem &/* option */,
  8.                                         const QModelIndex &/* index */) const
  9. {
  10.     QLineEdit *editor = new QLineEdit(parent);
  11.  
  12.     connect(editor, SIGNAL(returnPressed()), m_mc, SLOT(getValue() ) );
  13.  
  14.     //connect(editor, SIGNAL(textChanged(QString)), editor, SLOT(setText(QString)) );
  15.  
  16.     return editor;
  17. }
  18.  
  19. void LineEditDelegate::setEditorData(QWidget *editor,
  20.                                      const QModelIndex &index) const
  21. {
  22.     QString value = index.model()->data(index, Qt::EditRole).toString();
  23.  
  24.     QLineEdit *lineEdit = static_cast<QLineEdit*>(editor);
  25.     lineEdit->setText(value);
  26. }
  27.  
  28. void LineEditDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
  29.        const QModelIndex &index) const
  30. {
  31.     QLineEdit *lineEdit = static_cast<QLineEdit*>(editor);
  32.     double value = lineEdit->text().toDouble();
  33.  
  34.     model->setData(index, value, Qt::EditRole);
  35. }
  36.  
  37. void LineEditDelegate::updateEditorGeometry(QWidget *editor,
  38.            const QStyleOptionViewItem &option, const QModelIndex &/* index */) const
  39. {
  40.     editor->setGeometry(option.rect);
  41. }
To copy to clipboard, switch view to plain text mode 



Qt Code: 
  1. void getValue(){
  2.     QModelIndex index = m_view->currentIndex();
  3.     double size = m_view->model()->data(index, Qt::DisplayRole).toDouble();
  4.  
  5.     //The size is ALWAYS the older value, not the last one
  6.     QMessageBox::information(0, "value", QString("%1").arg(size));   
  7. }
