        self.dataView.setModel(self.model)


    def information(self,name):
        self.addData(self.model,name)

    def createModel(self,parent):
        model=QStandardItemModel(0,1,parent)
        model.setHeaderData(self.TITLE,Qt.Horizontal,'TITLES') # I want to change 'TITLES' to the center or right side.

        return model

    def addData(self,model,TITLE):
        model.insertRow(0)
        model.setData(model.index(0,self.TITLE),TITLE)

You have to set the default alignment of the header.
A QTableView or QTableWidget have both an horizontalHeader() and verticalHeader(), but since a QTreeView/QTreeWidget only has the horizontal header, the function is simply header().

self.dataView.header().setDefaultAlignment(Qt.AlignRight|Qt.AlignVCenter)

The vertical alignment is not usually necessary, I've just added it for completeness.
