QUICK REFERENCE: SystemWindow, LayoutFrame and Color

We have used, inside the Workspace, in the previous lesson, some Classes of the Squeak API to put the island inside the page. Let's see selected elements of them. 

 
SystemWindow


addMorph: aMorph fullFrame: frame

                                          aMorph is some object of a Class descendant (a subclass of a subclass of...)
                                          of the Class Morph. Can be a Croquet island.
  
                                          TIP: An   island has  two main Classes, one of the type
                                          Master and another of the type World. 
                                          To create an "object island" we use the Master. Something like:
                                          nm:= NavigatorMaster new  openInWorld   
                                                        
                                          frame  can be an object of the
                                          Class: LayoutFrame, by example.

fullScreen                                to "fullscreennize" the window.

openInWorldExtent: w@h                    set values for width and height.

 

setLabel: string

setWindowColor: color                     color can be an object of the Class:
                                            Color

rightFraction:n                   n is a number between 0.1 and 1 defining
                                     the limit of the object inside the window

lefttFraction:n                   n is a number between 0 and 0.99 defining
                                     the limit of the object inside the window

topFraction:n                     n is a number between 0  and 0.99 defining

Color                              Don't need to be created an object-reference.
                                     We use: Color r:n g:n b:n
                                     where n is between 0 and 1;
                                     or we use the directly: Color:name-of-the-color
