wxWidgets 是一个开源的跨平台的C++构架库（framework），它可以提供 GUI（图形用户界面）和其它工具。
wxWidgets 3.1.1 候选版本发布，与3.0版本相比，此版本有几个向后不兼容的更改。
- Support for gesture events has been added (GSoC 2017 project).
- New wxSecretStore class for securely storing user passwords.
- wxWidgets can now be built with CMake too.
- Strings can now be translated differently depending on their context.
- Converting between wxString and UTF-8 encoded std::string is now
simpler and unsafe wxString can now be disabled on the opt-in basis
- It is possible to use any window (e.g. wxCheckBox) as wxStaticBox label now.
- Many improvements to accessibility support under MSW.
- wxGraphicsContext now supports pens with fractional widths.
- Support for XDG file layout under Unix.
- Many bug fixes to the behaviour (including TAB navigation) and appearances,
especially in wxGTK3 and wxOSX ports.
- wxDataViewCtrl items and headers can be formatted using simple markup
and it is simpler to combine to put items with checkboxes into it. Many bugs
and inconsistencies between platforms in this control have been fixed too.
- Several enhancements to wxStyledTextCtrl including better support for
custom lexers and auto-completion.
- Many improvements to the (still experimental) wxQt port.
