Is it possible to add the MagickWand API calls into the IDE so the code insight or whatever its called can pick them up and offer completion a and parameter hint functionality

I'm not sure what MagickWand API is. Would you post a sample demonstrating its usage? Just a "caller" and a "callee".

Sorry, forgot to mention that!

Its a PHP interface to ImageMagic functionality (and thus VERY useful!)....

I'm afraid I have no time to start learning that from the beginning.
Please contact support and provide a sample illustrating the problem.

There isn't a problem, I suspect I worded my original question badly - sorry about that.

I was simply wondering if there was a way to add the API functions into the Code Insight function of the editor so that it prompts for the appropriate function arguments and has the constants defined.

i.e. like when you type 'mysql_connect(' into the editor a tooltip pops up and prompts you for the arguments to the function.

Looks like this is a php library and it is not in the project directory tree.
In this case you may want to add the library path to the Code Insight Includes list (see project properties). After the library is parsed, Code Completion will start working with all the objects in the library.

Ah, nice one!
