[Qt-interest] Problem with QLineEdit in QTableWidget

[Maximilien Renard]

Hi there,

I'm having some troubles with a little app I'm creating. I'm trying to
code a little script for this app which will allow me to edit, add,...
QSettings variables.
Therefore, I'm trying to display all the vars in a QTableWidget with
several other widgets. This is how it looks like :
_______________________________________________________________________________________
|                                  |
            |                             |
         |
|  QString(Key Name) |  QPushButton(Edit Key Type) |  QLineEdit(Value)
|  QCheckBox(Remove) |
|                                  |
            |                             |
         |
--------------------------------------------------------------------------------------------------------------------------

The 3rd cell's widget is not always a QLineEdit (depending on the Key
Type). It works fine with QDoubleSpinBox,... but not with QLineEdit.

My problem is : when I set the current value of the Key with
setText(), the text isn't displayed. When retrieving it with text()
it's OK but it is not shown. As soon as I type something into it, the
key value is replaced and the new text is displayed.

I couldn't figure out what I'm doing wrong and it's very annoying !

http://code.google.com/p/booksellermanager/source/browse/trunk/src/dialogconfig.cpp
here is the complete code and here is a little part of it :

			} else if(m_SettingsList.at(i)->GetKeyType() == QVariant::String) {
				m_KeyTypeWidgetsList.append(new QPushButton(tr("Change type (string)")));
				QLineEdit * LineEdit = new QLineEdit;
				LineEdit->setText(m_SettingsList.at(i)->GetKeyValue().toString());
				qDebug() << LineEdit->text();
				m_KeyValueWidgetsList.append(LineEdit);
				connect(LineEdit, SIGNAL(textEdited(QString)), this, SLOT(ValueChanged()));
			}
                        (....)
			connect(m_KeyTypeWidgetsList.at(i), SIGNAL(clicked()), this,
SLOT(TypeChanged()));

			m_RemoveKeyWidgetsList.append(new QCheckBox(tr("Remove")));

			m_TableWidget->setItem(i, 0, new
QTableWidgetItem(m_SettingsList.at(i)->GetKeyName()));
			m_TableWidget->setCellWidget(i, 1, m_KeyTypeWidgetsList.at(i));
			m_TableWidget->setCellWidget(i, 2, m_KeyValueWidgetsList.at(i));
			m_TableWidget->setCellWidget(i, 3, m_RemoveKeyWidgetsList.at(i));


I'd appreciate any help !

Many thanks,

Best regards,

Maximilien

P.S. If you're wondering why I'm not directly using the cell (it seems
possible) to enter text, that's just because I don't want to do that
