[PyQt] Synchronized scrolling between two tables

[Nader Abedrabbo]

Thanks Guys, 

I found the solution to my problem. 

By linking to the tables scroll bar via (QScrollBar) I now have access to
the bar.  Then using the signals emitted by the slider via (QAbstractSlider)
I can get the current location of the bar and then sync the other table with
it. 

Here is a short example (right table syncs with left, I just need to add
another signal for left table to synch with right).

class MyWindow(QWidget):
    def __init__(self, *args):
        QWidget.__init__(self, *args)
       
        self.tableWidget1 = QTableWidget()
        self.tableWidget2 = QTableWidget()
        numRows = 40
        numCols = 2
        self.tableWidget1.setRowCount(numRows)
        self.tableWidget1.setColumnCount(numCols)
        self.tableWidget2.setRowCount(numRows)
        self.tableWidget2.setColumnCount(numCols)
       
        layout = QHBoxLayout(self)
        layout.addWidget(self.tableWidget1)
        layout.addWidget(self.tableWidget2)

        self.setLayout(layout)

        self.sliderBar1 = self.tableWidget1.verticalScrollBar()
        self.sliderBar2 = self.tableWidget2.verticalScrollBar()

        QObject.connect(self.sliderBar1, 
                               SIGNAL("actionTriggered(int)"),
self.SyncScroll)
       
    def SyncScroll(self):
        sliderValue = self.sliderBar1.value()
        self.sliderBar2.setValue(sliderValue)



def main():
    app = QApplication(sys.argv)
    w = MyWindow()
    w.show()
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()
