[PyQt] selecting an item in qtreewidget

[Jason Rahm]

That was it, thank you!  I did have to add an int in the item.text(0) to do away with a not enough arguments error.  So thankful for all the helpful people on this list.  What a great community.

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:
