Question

我的QTableWidget行数有限。我想让用户按RETURN键插入一行，如果他们在最后一行按RETURN并且没有编辑单元格（双击鼠标进入编辑模式）。

正在编辑单元格：

代码是这样的，我不知道如何填充[当前单元格未被编辑]：

class MyTable(QTableWidget):
    def KeyPressReturn(self, event):
        if event.key() == Qt.Key_Return:
            if .currentRow() is the last row] and [current cell is not being edited]:
                insertRow(last_row_number)

Answer 1

一次只能编辑一个单元格。所以你只需要检查当前行是最后一行，并且表state不在edit mode中：

    if (self.currentRow() == self.rowCount() - 1 and
        self.state() != QtGui.QAbstractItemView.EditingState):
        # add a new row

Answer 2

This is the one example to insert the new Column and Row. I think this you exception.
If your are not expecting this answer, sorry once again.

class Window (QtGui.QWidget):
    def __init__(self, parent=None):        

        super(Window, self).__init__(parent)

        self.tableWidget = QtGui.QTableWidget(self)
        self.tableWidget.setGeometry(QtCore.QRect(10, 20, 511, 192))
        self.tableWidget.setObjectName('tableWidget')
        self.tableWidget.setColumnCount(0)
        self.tableWidget.setRowCount(0) 

        self.pushButton = QtGui.QPushButton(self)
        self.pushButton.setGeometry(QtCore.QRect(20, 220, 101, 23))
        self.pushButton.setObjectName('pushButton')
        self.pushButton.setText('Add')

        self.pushButton.clicked.connect (self.addItem)
        self.tableWidget.cellClicked.connect (self.addLine)        


    def addItem (self) :   
        columnCount     = self.tableWidget.columnCount ()
        rowCount        = self.tableWidget.rowCount ()        

        item            = QtGui.QTableWidgetItem()
        self.tableWidget.setVerticalHeaderItem (columnCount+1, item)

        item            = QtGui.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(rowCount+1, item)        

        self.tableWidget.setColumnCount(columnCount+1)
        self.tableWidget.setRowCount(rowCount+1)

    def addLine (self) :
        rowCount        = self.tableWidget.rowCount ()         

        item            = QtGui.QTableWidgetItem()
        self.tableWidget.setHorizontalHeaderItem(rowCount+1, item)            
        self.tableWidget.setRowCount(rowCount+1)       


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    w = Window()
    w.show()
    sys.exit(app.exec_())

如何知道QTableWidget的单元格是否被编辑？
