An instance of the class TheWorldMenu is shown as a World menu when the user clicks the Red button on the desktop. (Actually the desktop is the World, an instance of PasteUpMorph).


Cuis maintains the class TheWorldMenu.

Squeak 5.1
 TheWorldMenu selectors size 96
 TheWorldMenu class selectors size  9

 TheWorldMenu selectors size  41 
 TheWorldMenu class selectors size  0 

So reading code in Cuis can help you to better understand what is going on in Squeak.

TheWorldMenu saveWorldInFile


The following code snippet leads you to a point of departure for reading the code for TheWorldMenu.

(TheWorldMenu new
	world: World
	project: Project current  
	hand: World currentHand) 
buildWorldMenu openInWorld.

The message #openInWorld is sent here to the instance of the class TheWorldMenu just for demonstration purposes. The menu shows up in the upper left corner.

Look at PasteUpMorph>>buildWorldMenu: to see how the menu is used in context.

The method #buildWorldMenu of the class Dynamic open menu is the entry point worth exploring.

A part of the world menu is now dynamic. Your own application can register for an entry in the world menu (see Dynamic open menu for details)
