I tried doxyblocks, but it seems that it only doubles functionality of doxywizard. My question was about display documentation in codeblocks.
to see doc, i.e. description of function parameters I have to minimize c::b and switch to browser, open documentation, search for function, remember parameters meaning and switch back to c::b. My intention was to display documentation in floating window above autocompletion. Something similar to
http://netbeans.org/images_www/v7/1/screenshots/editor.png , for example:
And I agree that doxygen is the best tool to generate documentation, and IMO codeblocks should use its to generate docs.
Codeblocks already have (mostly unused) html viewer, maybe it can be used to display documentation? It is possible to make popup floating window with this viewer inside? It can be nice replacement for scintilla's call tip.
