Q:

How to Auto-scroll QT Text Field Widget

A code below creates a window with QTextBrowser widget. 
For five seconds the new lines of text added to QTextBrowser using
its .insertPlainText() method. 
As soon as text fills an entire field QTextBrowser automatically adds a scroll bar. But it does nothing to scroll down so the last line of text would be always visible (or readable) by the user. 
I would like to know how to make QTestBrowser scroll down automatically so the last line of the text is always within its text field or visible. How to achieve it?
Screenshot:

Code:
import sys, time
from PyQt4 import QtCore, QtGui

class MyDialog(QtGui.QDialog):
    def __init__( self, parent = None ):
        super(MyDialog, self).__init__(parent)
        self._console = QtGui.QTextBrowser(self)        
        layout = QtGui.QVBoxLayout()
        layout.addWidget(self._console)
        self.setLayout(layout)
    def updateField(self):
        for m in range(5):
            for n in range(100):
                self._console.insertPlainText('%s : '%n)
                QtGui.qApp.processEvents()
            time.sleep(1)

if ( __name__ == '__main__' ):
    app = None
    if ( not QtGui.QApplication.instance() ):
        app = QtGui.QApplication([])
    dlg = MyDialog()
    dlg.show()
    dlg.updateField()
    if ( app ): app.exec_()

A:

Just use .append instead of .insertPlainText to ensure auto scrolling:
    self._console.append('%s : '%n)
