[pyqt]Overriding operator< in QTreeWidgetItem

[kosset]

Hello!

Could you tell me how should I implement the override of operator< in QTreeWidgetItem?
I am asking because I can't find source code of original QTreeWidgetItem implementation in Python and I just don't know how it looks like.

hi,
i have the same question. did you solve it ?

[kosset]

I receive private messages with question whether I found the answer to my question. Unfortunately, I still don't know how to override operator. I even posted exactly the same question on PyQT mailling list: http://article.gmane.org/gmane.comp....iding+operator

Again, no response I got...

I promise to post solution as soon as I find the answer .

Please don't hesitate to post your own solution in this thread if you have it ...

hi, I'm sorry that I forgot to post solution i have found some time later:

class myTreeWidgetItem( QTreeWidgetItem ):
	def __init__(self, parent=None):
		QTreeWidgetItem.__init__(self, parent)
 
	def __lt__(self, otherItem):
		column = self.treeWidget().sortColumn()
 
		if column == 0 or column == 6 or column == 7 or column == 8: 
			return float( self.text(column) ) < float( otherItem.text(column) )
		else:
			return self.text(column) < otherItem.text(column)

class myTreeWidgetItem( QTreeWidgetItem ):
	def __init__(self, parent=None):
		QTreeWidgetItem.__init__(self, parent)
	
	def __lt__(self, otherItem):
		column = self.treeWidget().sortColumn()

		if column == 0 or column == 6 or column == 7 or column == 8: 
			return float( self.text(column) ) < float( otherItem.text(column) )
		else:
			return self.text(column) < otherItem.text(column)
