Why is the pen frozen?

[ETFVoyageur]

Consider the following code:

                line.index = Lines.Length;
                AddLine(line.color, line.value, line.name);
                //Lines[line.index].Pen.DashStyle = line.style;

The code this bit is from works fine, but only because of the commented-out line. If I uncomment the line, it throws because I am trying to write to a read-only property. Looking at it in the debugger, sure enough -- the pen is frozen.

Why? How an I supposed to set the line style?

Don't you want to use a Stroke instead?

Thanks for the suggestion.

I do not see that I have that choice, though -- I a trying to set dash style for a Line that is the result of an AddLIne(...) operation. I can see that theLine has a Pen, but I cannot see that it has a Stroke. It does have a StrokeStyle, but that is also read only. I don't see anything writeable that looks as if it takes a dash style.

Like you do for everything that is frozen. You clone the object, change the properties of the clone and then assign the clone to the old object. You can Freeze() the clone before assigning it if you want, or you can Freeze() the object after it has been assigned.

Things sure seem easier in the morning. Read your suggestion, kicked myself, and a few minutes later line styles and plot styles were working fine.

Thanks,
