Okay I partially figured this out and was able to add a scripting tile to my own category.

In the class additionsToViewerCategoryFraction I added a "slot" using:
(slot st1 'The quantity of Steve parts' Number readWrite Player getMajorTicks Player setMajorTicks:)


The part I was missing was I had to to Etoys-Scripting Player the getMajorTicks and setMajorTicks Methods.

I also found I can use command instead of slot.

Thanks,
Stephen

Subbu,

Thanks perhaps I should have been clearer in my question, I want to know how to create my own "property/command tile".  For example I want to create a new morph to create a number line object.   I would like to add a new "category" (ie:  like collections for a playfield) for my number line and add property tiles that can be dragged from the viewer into the script.

Bring up Etoys (scripting tool) for a morph by clicking on the 'eye' halo
icon. You will get a flap containing property and command tiles for that morph.
You can drag the "empty script" tile into the world to get an empty scriptor.
Or drag any desired property/command tile from this flap and drop it into the
world and a scriptor will automatically be created around this tile. You may
drop further tiles from Etoys flap into this script to build a sequence of
tiles.

While scripting, you may find it useful to keep "All Scripts" (controls running
of scripts) and "Players" morph (list of morphs with scripts) around.
