Draw lines with simplecv and pyqt4 - line

Question

I am trying to integrate simplecv to pyqt4 with some mixed success. I was able to see a webcam capture in pyqt4 through simplecv, I can modify the image with simplecv and it shows ok in pyqt4 but when I try to add a geometry or text to the image it is not showing in pyqt4. If I run the simpleCV code on their own it works OK. Can someone help me understand why it is not working? By the way, as you can see I am new to pyqt4 and simpleCV. See the code that I currently have.
#!/usr/bin/env python
import os
import sys
import signal
from PyQt4 import uic, QtGui, QtCore
from webcamGUI3 import *
from SimpleCV import *
class Webcam(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self,parent)
self.MainWindow = Ui_MainWindow()
self.MainWindow.setupUi(self)
self.webcam = Camera(0,{ "width": 640, "height": 480 })
self.timer = QtCore.QTimer()
self.connect(self.timer, QtCore.SIGNAL('timeout()'), self.show_frame)
self.timer.start(1);
def show_frame(self):
ipl_image = self.webcam.getImage()
ipl_image.dl().circle((150, 75), 50, Color.RED, filled = True)
data = ipl_image.getBitmap().tostring()
image = QtGui.QImage(data, ipl_image.width, ipl_image.height, 3 * ipl_image.width, QtGui.QImage.Format_RGB888)
pixmap = QtGui.QPixmap()
pixmap.convertFromImage(image.rgbSwapped())
self.MainWindow.lblWebcam.setPixmap(pixmap)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
webcam = Webcam()
webcam.show()
app.exec_()
Any ideas?

I got my friend, is very simple you just add
  ipl_image = ipl_image.applyLayers()
see:
ipl_image = ipl_image = self.webcam.getImage().binarize().invert()
ipl_image.drawRectangle(30,50,100,100,color=Color.RED,width=3)
ipl_image.drawText('ola galera',80,190,fontsize=50)
ipl_image = ipl_image.applyLayers()
data = ipl_image.getBitmap().tostring()
image = QtGui.QImage(data, ipl_image.width, ipl_image.height, 3 * ipl_image.width, QtGui.QImage.Format_RGB888)
pixmap = QtGui.QPixmap()
pixmap.convertFromImage(image.rgbSwapped())
self.MainWindow.label.setPixmap(pixmap)
