Thank you, Doug.

I like maplets better than worksheets because in a maplet, I have control over the exact size and position of each component. When I use Maple to present something to my students, I would like it to look a certain way for uniformity. Also, I want to fit a certain amount of material on each page.

These are not extermely important reasons, however, so using embedded components in worksheets will have to work.

Thank you, Robert.

I would like to request both a mouse action in a Plotter, which already exists in a Plot Component in a Worksheet, and a continuous action for a slider, which also already exists for a Slider Component in a Worksheet.

How do you make such reqests?

Thank you very much. It does work. I tried to put in my procedure

p:=plots[animate](

etc. and then in my Maplet

Plotter[P](p,

etc. thinking that this p would be replaced by the definition for p above when calling in the procedure.

Thank you so much for replying.

However, I have been trying to use the v in your example in the limits of animation for a plot like this:

> GetIt := proc()
   local v,p;
   v:= Maplets:-Tools:-Get('SL1');
   p:=plots[animate](plot,[x+t,x=-5..5,y=-5..5],t=0..v);
  end proc:
but when it comes to evaluating 'GetIt' I get the error message

"t=0..v is not valid as the limits of animation."
How come v is an integer, yet it cannot be used as the upper limit of animation?

Thank you so much for replying! I do see that it is going to be very hard to do.

What I have in mind is a Maplet that would display an expression like

12 / ( 1 - | 2^2 - 3^2 | )

and then on clicking a button, the Maplet would display the expressions

12 / ( 1 - | 4 - 9 | )

12 / ( 1 - | -5 | )

12 / (1 - 5 )

12 / (-4)

-3

one by one, showing in what order the operations are performed.

My only problem is to make Maple keep the exact form of each expression as it is intended.

It seems to me that Maple really should have a simple way of displaying expressions in this literal way, but oh, well...

I have actually tried that one, but I always get an error message that's something like

"cannot parse ... " followed by a bunch of MathML code (obviously the MathML version of the expression entered).

The only way I was able to do the kind of thing you are suggesting was by first creating a procedure1 including something like

MathML[Import](Get(MathMLEditor1));

and then putting

Evaluate('function'='procedure1' etc.)

inside a Button element in my Maplet.

Is there an easier way?

Thank you very much!
