[Codelite-developers] How to retrieve type data from the tags database

[Mattia B. <ma...@de...>]

  Hi,
I am trying to access the type information stored in the tags database
that is used for code completion, and I am failing miserably.

  I am trying to create a context help plugin: when the plugin is
correctly configured, hitting "F1" when the cursor is over an
expression should bring up the help topic for the type under
the cursor.  To do that I need to retrieve the type of the
expression under the cursor; for example

  wxString foo;
- I need to know that "foo" has type wxString

  window->GetBackgroundColour().GetAsString().length()
- I need to retrieve the type of "window"
- when the cursor is over "length" I'd like to know
  that the left-hand side has type wxString

  I experimented with Language::ProcessExpression and
TagsManager::AutoCompleteCandidates but I could not make them
work even in relatively simple test cases, like the two above.

  Could somebody point me in the right direction?

Thanks!
Mattia

P.S.: the examples above are C++/wxWidgets, but I'd be happy even
      if the solution worked for C code only
