Replacement for TextDisplayMorph
by Ralph Boland 04 Jun '10

04 Jun '10

I started using squeak with Squeak 3.6 and one of the classes I used was TextDisplayMorph. At some point this class disappeared from Squeak so I just carried it forward. But now I would like to get rid of it and use whatever one is supposed to use instead of a TextDisplayMorph. The key property I am looking for is that the user cannot edit the text in the morph. My best guess as to the replacement for TextDisplayMorph is PluggableTextMorph but of course it allows the user to edit the text. What class do I use to replace TextDisplayMorph and if the answer is PluggableTextMorph how am I supposed to make the text not editable by the user? Alternatively could someone point me to code in Squeak that I could study to find my answer? Thanks Ralph Boland -- Quantum Theory cannot save us from the tyranny of a deterministic universe but it does give God something to do
