Constructor Detail

AddLOTypeCommand

public AddLOTypeCommand(String name,
                        org.eclipse.swt.graphics.RGB titleFore,
                        org.eclipse.swt.graphics.RGB titleBack,
                        org.eclipse.swt.graphics.RGB bodyFore,
                        org.eclipse.swt.graphics.RGB bodyBack,
                        int sourceRoleKey,
                        String sourceRoleName,
                        int targetRoleKey,
                        String targetRoleName)

constructs a new LOType.

In all cases colours and a name must be provided. The Role information however is slightly more complex:

• If the user has pointed to an existing Resource as the role, give its key as the value for sourceRoleKey or targetRoleKey.
• If the user has given a name and not a Resource the system should create a new Resource with the given name. In this case give the name and give the Key value as 0.

Parameters:

name - String name of new LOType.

titleFore - RGB of color for title Foreground.

titleBack - RGB of color for title Background.

bodyFore - RGB of color for body Foreground.

bodyBack - RGB of color for body Background.

sourceRoleKey - int key to Resource to act as source Role

sourceRoleName - String name of Resource to be created to act as source Role

targetRoleKey - int key to Resource to act as target Role

targetRoleName - String name of Resource to be created to act as target Role
