1.updating方法,作为Gui Controller类中的插槽来管理输入
def tbRobotChanged(self, currentCell):
# get the selected cell's index from currentCell,Implement the Slot method
tablemodel= currentCell.model()
#get the model of the currentcell
firstColumn = tablemodel.index(currentCell.row(),0)
#change it to the first column in the row with the robot name
self.statusBar().showMessage("Selected Robot is " +
firstColumn.data().toString())
self.selected_robot = int(firstColumn.data().toString())
# show the selected robot name in the statusbar
2.table定义,这是定义主窗口的Gui类的一部分:
def initRobotsFrame(self, rf):
hbox = QtGui.QHBoxLayout()
self.robot_table = QtGui.QTableView()
self.table_header = ['Robot', 'PosX', 'PosY', 'Heading']
tm = RobotTableModel([[0, 0, 0, 2],[1, 1,2,4]],
self.table_header)
self.robot_table.setModel(tm)
vh = self.robot_table.verticalHeader()
vh.setVisible(False)
self.robot_table.resizeColumnsToContents()
self.robot_table.setSizePolicy(QtGui.QSizePolicy(
QtGui.QSizePolicy.Minimum,
QtGui.QSizePolicy.Minimum))
hbox.addWidget(self.robot_table)
self.selected_robot = 0
block_true=GUIController.robot_data.blockSignals(True)
GUIController.robot_data.blockSignals(block_true)
# select table by row instead of by cell:
self.robot_table.setSelectionBehavior(
QtGui.QAbstractItemView.SelectRows)
# set the signal and slot using selectionModel:
self.robot_table.selectionModel().currentRowChanged.connect(
self.tbRobotChanged)
self.robot_table.selectionModel().currentRowChanged.connect(
self.updateActiveRobot)
# implement a statusbar to test the table selection functionality:
self.statusBar().showMessage("Ready")
rf.setLayout(hbox)
3.slot获取所选行的数据:
def tbRobotChanged(self, currentCell):
# get the selected cell's index from currentCell,Implement the Slot method
tablemodel= currentCell.model()
#get the model of the currentcell
firstColumn = tablemodel.index(currentCell.row(),0)
#change it to the first column in the row with the robot name
self.statusBar().showMessage("Selected Robot is " +
firstColumn.data().toString())
self.selected_robot = int(firstColumn.data().toString())
# show the selected robot name in the statusbar
