wxDataViewCtrl code expects, quite reasonably, that NSCell's cellSize: will behave as documented and return the minimal size for image cells too. Unfortunately, that's not the case. A cell created as NSImageCell, which seems to exists for exactly this purpose, will always return the size as (0,0), regardless of whether it has any image set or not an regardless of its size. On the other hand, a cell created with NSCell.imageCell constructor sizes itself correctly, but is not a NSImageCell instance and somehow interferes with other wxDataViewCtrl rendering, presumably due to its special status. The simplest fix to make the sizing work correctly therefore seems to be to specialize NSImageCell and implement its (trivial) cellSize: method.
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 http://docs.wxwidgets.org/
Platforms
wxWidgets currently supports the following primary platforms:
- Windows XP, Vista, 7, 8 and 10 (32/64 bits).
- Most Unix variants using the GTK+ toolkit (version 2.6 or newer or 3.x).
- OS X (10.7 or newer) using Cocoa (32/64 bits).
Most popular C++ compilers are supported including but not limited to:

- g++ 3.4 or later, including MinGW/MinGW-64/TDM under Windows.
- Clang under OS X and Linux.
- Intel icc compiler.
- Oracle (ex-Sun) aCC.
Licence
wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.
