Connect to key-{press,release}-event on the "focus widget" rather than
the main widget, to ensure that we get them before the native control
does and so can generate the key events even for the keys handled by the
control internally.
This allows to get events for the arrow keys in wxDataViewCtrl, for
example, while previously these keys were consumed by the control
itself, as could be seen with the following patch to the sample

Pressing arrow keys didn't generate the expected message before (unless
the focus was on the control header and not on the main area itself).
This may fix similar issues with other controls setting m_focusWidget as
well.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at https://docs.wxwidgets.org/

For building the library, please see platform-specific documentation under
docs/<port> directory, e.g. here are the instructions for
wxGTK, wxMSW and
wxOSX.
If you're building the sources checked out from Git, and not from a released version, please see these additional Git-specific notes.
