I'm trying to go back to beginnings with my own ManelBrot morph because I can quite grok how the one I have works.
Mostly because I still dont grok morphs.
Example: I'm trying to plot points on a morph using the drawOn message below:
Paint into a Form. Draw the form in #drawOn:.
I'm sorry, I don't understand.
Isn't this "painting" into a Form?
aCanvas form colorAt: 30@30 put: Color black.
No, that's painting directly onto the Display (a.k.a. the canvas's form), which is considered bad style in Morphic.
My problem is that the pixel doesn't stay set.
30@30 would be in the upper-left corner of the Display. Unless your morph covers that, you won't see it.
You might try "self topLeft + (30@30)" but again, that's bad style.
In any case, I thought your question was about displaying the Mandelbrot set. It would be wise to paint that into a form, preferably in a background process. Then just update the display (by drawing the form) once a second until it's finished.
