The general rule is that there are properties in a class for any 
non-static method that has a GetFoo name that takes no parameters.  If 
there is also a matching SetFoo that takes only one parameter then it 
will be set as the setter for that property.

I assume you are talking about wx.Frame here.  There is no GetStatusText 
so there is no property, so you are just assigning to a normal attribute 
named StatusText.

No, it is a staticmethod.

No getter for the first.  There is a property for 'Sizer' though.

No matching getters.

No getter

No getter

No, but there are properties for 'Min' and 'Max'

Yes, but there shouldn't be because the getter takes a parameter, and 
the setter takes more than one.  It's a bug that there is one there 
currently.

Each of these has too many parameters.

BTW, the properties are all listed in the class docs in the 
Python-specific docs at http://wxpython.wxcommunity.com/docs/api/
