Thank you for this example. It saved me quite some searching time.

(.. On my machine I had to alter "from Qt import *" into "from PyQt4.QtGui import *")

#2 Eliot commented on 2009-06-29:

Bastian, yes I think from PyQt4.QtGui import * is the correct import statement now. I think from Qt import * was the old way. Thanks for your comment.

How can I copy and pasty all the data from the whole table?

#4 Ryan Bales commented on 2009-12-16:

Fantastic examples you have here. One thing I would do differently is to make use of enumerate() to index your for loops.

I would rework the above like...

def setmydata(self):
    for n, key in enumerate(self.data):
        for m, item in enumerate(self.data[key]):
            newitem = QTableWidgetItem(item)
            self.setItem(m, n, newitem)

Ryan, Thanks. I agree your modification is much better. I learned about enumerate a couple years after I originally wrote this. (Also, I added one blank line in your comment before your code block so the formatting would come out correctly.)
