title: wxWidgets, wxAUI, wxDockIt: who uses it?
body: <p>I am looking for a library which will help me create applications with a native look and feel for Linux, Mac and Windows (mainly Windows).</p>
  
  <p>I don't know a lot about the different libraries (GTK+, Qt, wxWidgets, etc.) but as I have understood, wxWidgets respects the OS API for rendering GUI controls, and it still works for older OS's (which I will be targetting too).</p>
  
  <p>Now my question is: how widely used is wxWidgets? Did Microsoft use it for their office software, like Word and Excel for example?</p>
  
  <p>I have tried installing wxDockIt (which I believe is not part of wxAUI?) using MinGW, but it failed. I ran following command (as stated in C:\wxDockit\installation.txt):</p>
  
  <pre><code>C:\wxDockit\build\msw&gt;mingw32-make -f makefile.gcc
  </code></pre>
  
  <p>This gives the following output:</p>
  
  <pre><code>g++ -c -o mingwd\wxdockit_lib_dockpanel.o -DHAVE_W32API_H  -D__WXDEBUG__ -D__WXM

  </code></pre>
  
  <p>And my last question: Does wxAUI or wxDockIt have cross platform support for all three OS's (Linux, Mac and Windows)?</p>
  
  <p>Thanks in advance</p>
