Hi Mark,
what you show is ok. But my problem is different.
Imagine a child in front of a timestable application.
She sees a question ("8 x 3 =") and there is another field where she is
supposed to type the answer (a TextMorph).
The answer field is supposed to be empty except for a cursor indicating that
you may type your answer here.
When typed, the figures are supposed to appear in a big font size.
My problem: Until now I did not succeed to initialize a TextMorph in a way that
fulfills my requirements.
Kind regards
Pascal
