Drawing a line

Hello!

Task is simple - draw a line on a form(actually this line will be a border of a cell). While browsing classes I found LineSegment and LineMorph. Which of them is better to use in my case? And another question: I know how to initialize both of them, but don't know how to draw it on my form.

Thank you for help.

Re: Drawing a line

Hi Mark,

sadly, I’m not confident about this, but maybe you should use Athens

hi,

I think you need LineMorph.
AFAIK, LineSegment is just used to draw PolygonMorph (not sure about that)

myForm getCanvas line: pt1 to: pt2 width: w color: c

You only need to use a LineMorph if the line is not supposed to be static, otherwise drawing it directly on the Form is just as easy.

Unless what you actually want is to create something like a spreadsheet, in which case a CellMorph, with RectangleMorph (cell outline) / StringMorph (cell contents) as subcomponents would probably be a better solution.
(And the spreadsheet itself a morph, with CellMorphs as subcomponents)

Cheers,
Henry

Re: Drawing a line

Problem is solved)

Looked at Canvas class and used it, as some of you adviced.

As for me it was the best choice for such a simple task.

Thank you again.
