At ESC 2015 SV I gave a talk on using USB From Python, see the talk description here. This blog post is serving as a placeholder to allow me to update links to software used during the live demo.

For SuperCon 2015, there is a Project Page with these details too. You can also ask questions on the project page.

There is two versions of the slides. Use the SuperCon slides, but I left a copy of the ESC ones here in case you wanted the original for some reason.

QTabWidget in PySide Automatically Resize

When using PySide, a QTabWidget is handy. But the size of the QTabWidget is dictated by the largest item, even if it’s not visible. Let’s assume self.tw is our tab widget. Then add this function:

from PySide.QtCore import *
from PySide.QtGui import *

class MainWindow(QMainWindow):
 def curTabChange(self, index):
 for i in range(self.tw.count()):
 if i == index:
 self.tw.widget(i).setSizePolicy(QSizePolicy.Preferred, QSizePolicy.Preferred)
 else:
 self.tw.widget(i).setSizePolicy(QSizePolicy.Ignored, QSizePolicy.Ignored)

 def myOtherFunction(self):
 etc etc etc

And in your initialization associate it with a tab change event:
