How to edit Horizontal Header Item in QTableWidget

[luoyes]

Thanks for your answer. However, what I wanted to achieve was to implement this functionality for the header items and not substitute the header items with simple items that simple look-like header items. Is there any oter way to actually edit the horizontal heaer items?

Did you find any method to edit the header items?
I want to insert a comboBox to the header item,but it seems that it's impossible.

I am interested also if anyone has figured out how to do this. I am using PyQt4. I have tried various things such as setting the header item to a QLineEdit object but have not gotten anything to work. I understand how patrik's solution would work but it seems to me that you should be able to make the Headers editable directly.

I found a solution to this at least in PyQt I feel its kind of a hack but that is only because the headerview can't use delegates. I also posted this on another thread but I don't know how to link them.

class MetaHeaderView(QtGui.QHeaderView):
 
    def __init__(self,orientation,parent=None):
        super(MetaHeaderView, self).__init__(orientation,parent)
        self.setMovable(True)
        self.setClickable(True)
        # This block sets up the edit line by making setting the parent
        # to the Headers Viewport.
        self.line = QtGui.QLineEdit(parent=self.viewport())  #Create
        self.line.setAlignment(QtCore.Qt.AlignTop) # Set the Alignmnet
        self.line.setHidden(True) # Hide it till its needed
        # This is needed because I am having a werid issue that I believe has
        # to do with it losing focus after editing is done.
        self.line.blockSignals(True)
        self.sectionedit = 0
        # Connects to double click
        self.sectionDoubleClicked.connect(self.editHeader)
        self.line.editingFinished.connect(self.doneEditing)
 
    def doneEditing(self):
        # This block signals needs to happen first otherwise I have lose focus
        # problems again when there are no rows
        self.line.blockSignals(True)
        self.line.setHidden(True)
        oldname = self.model().dataset.field(self.sectionedit)
        newname = str(self.line.text())
        self.model().dataset.changeFieldName(oldname, newname)
        self.line.setText('')
        self.setCurrentIndex(QtCore.QModelIndex())
 
    def editHeader(self,section):
        # This block sets up the geometry for the line edit
        edit_geometry = self.line.geometry()
        edit_geometry.setWidth(self.sectionSize(section))
        edit_geometry.moveLeft(self.sectionViewportPosition(section))
        self.line.setGeometry(edit_geometry)
 
        self.line.setText(self.model().dataset.field(section).name)
        self.line.setHidden(False) # Make it visiable
        self.line.blockSignals(False) # Let it send signals
        self.line.setFocus()
        self.line.selectAll()
        self.sectionedit = section

        self.model().dataset.changeFieldName(oldname, newname)
        self.line.setText('')
        self.setCurrentIndex(QtCore.QModelIndex())

    def editHeader(self,section):
        # This block sets up the geometry for the line edit
        edit_geometry = self.line.geometry()
        edit_geometry.setWidth(self.sectionSize(section))
        edit_geometry.moveLeft(self.sectionViewportPosition(section))

        self.line.selectAll()
        self.sectionedit = section
