2. the C++ versions of wxSizer and firends, Python versions are 'depreciated' 3. wxPyEvent and wxPyCommandEvent, event classes that can carry some python objects through the event system and safely come back out again. 4. wxGridSizer and wxFlexGridSizer 5. wxValidator 6. wxPyOnDemandOutputWindow 7. several tweaks, fixes and additions of missing methods, etc. 8. and probably several other things I am forgetting since CVS was down so long... git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@3758 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

overview = """\
|
|
wxValidator is the base class for a family of validator classes that mediate between a class of control, and application data.
|
|
|
|
A validator has three major roles:
|
|
|
|
1. to transfer data from a C++ variable or own storage to and from a control;
|
|
|
|
2. to validate data in a control, and show an appropriate error message;
|
|
|
|
3. to filter events (such as keystrokes), thereby changing the behaviour of the associated control.
|
|
|
|
Validators can be plugged into controls dynamically.
