QUICK REFERENCE: TEXT

Some objects of Squeak have a graphic appearance that you can see in the Squeak desktop when it is instantialized. This instantialization can be made dragging from the "green window" (Object window).

Many methods of this objects can be executed in "design time" using graphic resources. We will try, at this Quick Reference, to mix this kind of methods and the methods normally executed inside scripts.

In the serie of lessons we are beginning now, we will present objects or group of objects to be used like "Form Controls", that have different designations in other plataforms: Text, Label, TextField, TextBox, Button, ListBox, RadioButton etc.

A Text object is instatialized graphicaly dragging from the "green window":
