Question:I just wondered if you'd worked out a way to pop up a TextMorph in italic?
Answer: Ned Konz 21 December 2001
TextMorph new
contents: (Text string: 'this is something longer than normal' attribute: TextEmphasis italic);
fontName: #BitstreamVeraSans size: 24;
releaseCachedState; "—-added"
openInWorld
tm := TextMorph new.
tm contentsWrapped: ''; extent: 100@20. "this is the important stuff"
Set a font with:
tm beAllFont: ((TextStyle default fontOfSize: 36) emphasized: 1)
