The second reason is to remove what some perceive to be a "wart." For example, the following code is rather ugly in that the "wx" prefix on @@ -163,15 +163,100 @@ replace.

Where can I find example programs using the new wx syntax?

Example programs are included in the wxPython/samples/wx_examples -directory, and are documented in the wxPythonExamples documentation -file. Also, all the code in the py package uses the new wx syntax. -You can learn more about these in the PyManual.

The wxPython demo application and most of the sample apps have been +converted to use the new import wx style of programming with +wxPython, so there are lots of examples to look at and to play with. +Here is one of them, it is the simple sample.
