Using a Project

 

There are two buttons in the main menu of GRAPE's manager which are used to add and to remove projects:

When the button is pressed a list of all available projects appears. It may differ from program to program depending on which projects were compiled into the GRAPE library or added locally, but it should look somewhat like this:

Now you can select a project to add it to the system (the same project can be added several times though this only makes sense for projects which add objects to the data hierarchy tree). Removing projects is as simple as adding them: press the button and a list of all added projects appears, then select the one you want to delete. If a project was added more than once it has to be removed as often as it was added to really delete it from the system.

Projects can be declared as hidden, then they do not appear in the add list. In most cases this is done because they only make sense when they are used by other projects or because they are still under development and not intended for general use. Nevertheless they can be added by typing in the name, try for example surface (this project provides the user-interface for the abstract class Surface).

In addition to classes, methods and interactive elements a project may also provide its own objects, to add them to the data hierarchy tree the current object has to be a scene. Otherwise an error requester appears which offers to either add the project without its objects

(that is its classes, methods and interactive elements) or to abort adding it. The objects to add will be deleted in both cases.

Some projects install a user-interface in one (or several) of the option menus, where you can find it and how the project interface is used is described in the project's documentation in section 8.
