Clean Qt selection comboBox

Hi Everybody..

I am using Qt and need to build a selection comboBox -- e.g.:
http://www.java2s.com/Tutorial/VBIma...ntAddValue.PNG .

The problem is - after one choice was made, and the code run, for the next time the user select a different choice, both, the present and all past choices run. See what I mean:

Code:

selected color - blue
we are on runBlue
selected color - red
we are on runBlue
we are on runRed

Here is the code:

Code:

.........................................
QtCore.QObject.connect(self.selectComboBox, 
			QtCore.SIGNAL("currentIndexChanged(QString)"), 
			self.combo_activateInput)   
.........................................
def combo_activateInput(self):
        color=unicode(self.selectComboBox.currentText())
        if(color == "blue"):
            print "selected color - blue"
            QtCore.QObject.connect(self.okButton, QtCore.SIGNAL("clicked()"), self.combo_runBlue)
        if(color == "red"):
            print "selected color - red"
            QtCore.QObject.connect(self.okButton, QtCore.SIGNAL("clicked()"), self.combo_runRed)               
        if(color == "yellow"):
            print "selected color - yellow"
            QtCore.QObject.connect(self.okButton, QtCore.SIGNAL("clicked()"), self.combo_runYellow)
        del color 
.........................................
def combo_runBlue(self):
        print "we are on runBlue"

def combo_runRed(self):
        print "we are on runRed"

def combo_runYellow(self):
        print "we are on runYellow"

I run "del color" to clean the content returned by selectComboBox.currentText, but it didn't clean the content indeed.

So, any suggestion? All comments and suggestions are highly appreciated.

Here is the solution:

Code:

    def combo_runBlue(self):
        print "we are on runBlue"
        QtCore.QObject.disconnect(self.okButton, QtCore.SIGNAL("clicked()"), self.combo_runBlue)

Hope this can help others too.
