The itemClicked signal passes two parameters which you can receive in the
method you connect the signal to.

def __init__(self):
  self.treeWidget_iRulesList.itemClicked.connect(self.displayRule)
def displayRule(self, item, column):
  self.textEdit_ScriptCanvas.clear()
  self.textEdit_ScriptCanvas.setText('test ' + item.text() + ' column ' + 
str(column))

You could call the tree widget's setCurrentItem() method, passing the last
item. Whether the item will be selected, as well as made the current item,
depends on what the selection mode is. You can change that by calling
setSelectionMode() with the required value:
