Hello Marcus,
Thank you for your reply I have changed my signals and have set up a
function that tests for current data vs old data only when the table has
been populated.
Thank you for the help. For anyone who has a similar issue I have left my
test function below. Test cases seem to be working so far
self.uiMainWindow.uiUnitExtensionTable.itemDoubleClicked.connect(self.testData)
self.uiMainWindow.uiUnitExtensionTable.itemChanged.connect(self.testPrint)
def testPrint(self):
try:
self.newData =
self.uiMainWindow.uiUnitExtensionTable.currentItem().text()
row = self.uiMainWindow.uiUnitExtensionTable.currentItem().row()
print
self.uiMainWindow.uiUnitExtensionTable.verticalHeaderItem(row).text()
print "Item changed"
if self.newData != self.currentData:
print "Old data", self.currentData
print "New data", self.newData
else:
print "No new data", self.currentData
except:
pass
def testData(self):
try:
print "cell entered"
self.currentData =
self.uiMainWindow.uiUnitExtensionTable.currentItem().text()
except:
pass
