Element in a RichTextBox

I'm planning to use the RichTextBox as my Math editor.

For instance, if I want to insert the Squareroot of 32, I would insert a
Sqrt element and the numbers 3 and 2.
Since I want to benefit from all the editing features in a Rich Text Box, I
would like the Sqrt to be an element, just like 3 and 2 are.
Also, I want the Sqrt element to change the relative position of the 3 and
the 2 because 32 will be inside the Sqrt.
Finally, the Sqrt element representation would be the typical mathematical
symbol (the "v" with a long right arm).

Which element should I derive from to create Sqrt? From "Block"?
Where can I find more information on this?

Thanks.

I don't think it's possible for an element (Sqrt) to change the relative
position of other elements (32).

I have created a math equations library for WPF (
http://www.valil.com/winfx/math.html ) - the idea is to have the basic custom
controls for the equations. You can display any equation composing this
custom controls.
I haven't create a editor using this library, it's just for displaying the
equations.
I presume an editor will be conceptually the same as the Equation editor in
Word.

Hello Viliescu and thanks for your sample code (it's very nice btw).

I think it is possible to do, becouse it would work like a Paragraph or a
List.
Both of them afect their children.

What do you think?

Best regards.

I think I misunderstood you. Yes, it is possible to do that, in fact, this is
what I did in the library. I have created custom "containers" (panels) that
arrange their children in a specific way - for example, RadicalPanel arranges
its children (the index, the radical sign and the radicand) to look like a
radical.

Hello viliescu,

I don't think you missunderstood me the first time.
In my last post, I do think I didn't give you the right idea.

I want my equation objects to work as single elements in the FlowDocument,
so that the RichBoxEditor can treat them as a single element. This way, I
may move around each element in the equation and insert or delete single
elements in between.

In a short sentence: I want to have a real equation editor where each equation
particle is a single editable element.

I'm not sure I make may self understood. I hope so.

Thanks a lot.

In this case, I don't think it's possible to do that. Think about the
Equation Editor from Microsoft Word: the editing of equations is separate
from the document editing, you always have to change the context. I have
thought about this problem for a while and I think Word/Eq. editor is the
optimal way to go.

Anyway, I don't want to discourage you - I might be wrong (in fact I would
love to be wrong ), so maybe somebody else has some other ideas to make it
work like you said.
