wxPython: Converting wx.DateTime to Python datetime

The wxPython GUI toolkit includes its own date / time capabilities. Most of the time, you can just use Python’s datetime and time modules and you’ll be fine. But occasionally you’ll find yourself needing to convert from wxPython’s wx.DateTime objects to Python’s datetime objects. You may encounter this when you use the wx.DatePickerCtrl widget.

wxPython: How to Catch All Exceptions

One of my friends on the wxPython Google Group asked how to catch any exception that happens in wxPython. The problem is complicated somewhat because wxPython is a wrapper on top of a C++ library (wxWidgets). You can read about the issue on the wxPython wiki. Several wxPython users mentioned using Python’s sys.excepthook to catch

wxPython: An Introduction to Sized Controls

wxPython 201: Syncing Scrolling Between Two Grids

This week I saw a question on StackOverflow about putting two grids into a SplitterWindow which itself was in a Notebook page. Personally I think that’s a little convoluted, but I thought it was an interesting challenge and I came up with a solution. Then the fellow wanted to know how to sync the scrolling

wxPython: ObjectListview – How to Double-click items

The other day I was working on a project where I was using the fabulous ObjectListView widget (a wrapper around wx.ListCtrl) and I wanted to add the ability to double-click an item in the control to make it open a PDF. I knew I had read somewhere on the internet about how do this sort
