Text is a class similar to the class String. But the Text objects may include emphasis attributes such as italics or bold. So Text is a class which "wraps" an instance of String and attributes.
Every character may have its own attributes. The implementation is done in a space efficient way. The information is stored in a runs instance variable. Only the necessary attributes are stored and each change is indicated.
Class hierarchy: (Squeak 3.3a-4664 .. Squeak 5.3a)
ProtoObject #()
Object #()
Collection #()
SequenceableCollection #()
ArrayedCollection #()
Text #('string' 'runs')
A way to create a Text object from a string (no emphasis then):
Text fromString: 'hello world!'
With emphasis see: TextStream.
If the runs are available:
Text
string: string
runs: runArray
Or from HTML
Convert HTML to Text
