    <p>I have three classes, class Actor, class Cell, and class Behavior. Class Actor instantiates a subclass of Behavior (defined in the Behavior header file). Behavior uses methods to analyze vectors of pointers to Actors and vectors of pointers to Cells. Cells have methods that analyze vectors of pointers to Cells, and they contain vectors of pointers to Actors. Oh yes, and in the Actor header file there is an enumerated Heading data type utilized by all classes in some way. (incorporated by declaring an extern enum Heading data type in each file that includes Actor). </p> <p>I've got most of the code, but hit a sticking point when I got an enormous list of errors related to the includes and recursive includes, and have been toiling away at it for hours. I could use some help figuring out what is the best way to arrange these objects so that they work together. </p> <p>So, to re-iterate:</p> <pre><code>Actor: Behavior Behavior: vector of pointers to Cells, vector of pointers to Actors Cells: vector of pinters to Cells, vector of pointers to Actors Heading: Enumerated, declared extern in all classes, currently stored in Actor. </code></pre> <p>Any advice as to how to go about including which header files where? I've tried many many permutations of different forward declarations, includes, etc. I honestly don't know where to go now. </p> <p>Thank you!</p> <p>Edit: Updated my class and header files. </p> <pre><code>Actor: Move, Heading Move: Behavior Heading Behavior: Cell, Actor Heading Cell: Cell, Actor Heading Heading: Used by all. </code></pre> <p>As it stands, here are whats being included:</p> <pre><code>Behavior.h: Forward declarations of Cell and Actor Behavior.cpp: Includes Behavior.h, Cell.h, Actor.h Cell.h: Forward Declaration of Actor Cell.cpp: includes Cell.h, Heading.h, Actor.h Actor.h: Includes Behavior.h, Heading.h. Actor.cpp: includes actor.h Move.h: Includes Behavior.h, Heading.h Move.cpp: Includes move.h, Heading.h, Cell.h, Actor.h Heading: Includes nothing, declares nothing. </code></pre> <p>Pretty much the only include-related error I'm seeing is the one instantiation of Move in the Actor.h file has an incomplete type. </p> <p>Edit #2: Added includes for Behavior and Move in actor.cpp and removed them from actor.h, and turned my instantiation to the creation of a pointer, and it coughed and growled at me, but it built successfully. Thanks for your help guys!</p>

    1. COWhat kind of errors? Could you show us your classes?

    3. COI can't unfortunately. I can give you the gist, and say that my application will form a world of Cell objects, which in turn hold vectors of Actor objects and vectors of pointers to its neighbors (utilizing headings and other Cells). The Actor objects use the Behavior object to create a Move object to transport itself from Cell to Cell.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
