PyQt4, QTableView with QLineEdit as a QItemDelegate and selection

[mikecrowe]

Hi folks,

I'm having a strange problem. I have a grid of QLineEdits, QSpinBoxs, and other controls in a QTableView (see attached image). When I first create the page, every QLineEdit and QSpinBox item is selected.

I have tried things like:

def createEditor(self, parent, option, index):
        self.lineEdit = QLineEdit(parent)
        self.lineEdit.setValidator(QDoubleValidator(self.lineEdit))
        self.lineEdit.textChanged.connect(self.emitCommitData) 
        self.lineEdit.setText(self.getValue().toString())
        self.lineEdit.setAlignment(Qt.AlignVCenter|Qt.AlignRight)
        self.lineEdit.selectAll()
        self.lineEdit.setSelection(0, 0)
        return self.lineEdit

def createEditor(self, parent, option, index):
        self.lineEdit = QLineEdit(parent)
        self.lineEdit.setValidator(QDoubleValidator(self.lineEdit))
        self.lineEdit.textChanged.connect(self.emitCommitData) 
        self.lineEdit.setText(self.getValue().toString())
        self.lineEdit.setAlignment(Qt.AlignVCenter|Qt.AlignRight)
        self.lineEdit.selectAll()
        self.lineEdit.setSelection(0, 0)
        return self.lineEdit

To copy to clipboard, switch view to plain text mode 

and

def createEditor(self, parent, option, index):
        self.lineEdit = QLineEdit(parent)
        self.lineEdit.setValidator(QDoubleValidator(self.lineEdit))
        self.lineEdit.textChanged.connect(self.emitCommitData) 
        self.lineEdit.setText(self.getValue().toString())
        self.lineEdit.setAlignment(Qt.AlignVCenter|Qt.AlignRight)
        self.lineEdit.deselect()
        return self.lineEdit

def createEditor(self, parent, option, index):
        self.lineEdit = QLineEdit(parent)
        self.lineEdit.setValidator(QDoubleValidator(self.lineEdit))
        self.lineEdit.textChanged.connect(self.emitCommitData) 
        self.lineEdit.setText(self.getValue().toString())
        self.lineEdit.setAlignment(Qt.AlignVCenter|Qt.AlignRight)
        self.lineEdit.deselect()
        return self.lineEdit

To copy to clipboard, switch view to plain text mode 

to no avail. Also, I considered that it might be something in the QTableView, and have tried even deselecting the items in it too.

If I switch away from the window (alt-tab) and come back, all the text is deselected.

Can anybody point me in the right direction?

Hi Mike,

I have the same issue with QT 4.7.3 for c++. Do you have a solution yet?

Could be related to this bug? I had the same problem with a QSpinBox.
