I'll be glad to answed your questions, but for some of them I need to know what version of Squeak/Etoys you are using.

1. How can we combine two tools in supplies flap? e.g. Text and line, or Text and rectangle..so on.

I think I understand this question. If you want to put a rectangle that contains text into a supplies flap, you first get out a rectangle object, and then a text object. Place the text object over the rectangle, and look in the text object's red dot menu. You will see "embed ...". Choose this, and then choose "rectangle". Now the text object is a part of the rectangle object, but can still be edited. Now pick up the rectangle object and drop it into the supplies bin. It will show up there in a reduced size. Now you can drag copies out. (BTW, any playfield can be converted into a supplies bin. Look in its red menu for "playfield options".

2. How can we make tables and graphs with using squeak?

This is a good thing for children to learn. Each object in Etoys has a pen, so you can construct a grapher by making a small paint dot or pulling out an ellipse from the supplies bin (make it small). Put the pen down and choose the size and color of the ink. A simple graphing script is then: dot graph ticking dot's x increase by 1 dot's y <- <whatever value you want to graph, etc>

3. What is the "graph"'s function? I can see only one graph looks like a sine or a cosine graph.

This is a different kind of graph that is used for sound. These can be made in etoys but are more cumbersome than above.

4. What is the "ruler"'s function?

We haven't used this with children.

5. I tried to use "arrow editor", but i don't know exact function of "sample".

Are you using Etoys or regular Squeak. If Squeak, then these questions are best asked on the Squeak list (you can sign up on www.squeak.org).

How can we drag out a shown arrow to the world? I can drag out a word to the world though. 6. How can we make screen print?

Each object has an "export" in its red menu.

7. In "starsqueak", how can we use "slimemold" and "trees"? are they existed a sort of model? or can we use them for other projects? It seems to me that the couple of models looked like from logo

StarSqueak was derived from Resnick's StarLogo. We now use Yoshiki Ohshima's "Kedama", which is a particle system that can be programmed almost identically to the Etoys.

Best wishes,

Alan

I'm sorry that I didn't provide good help for the Arrow Editor. (If someone would like to write up a help text for it, I'd be glad to add a 'help' button to the editor).

The arrow editor lets you define new end decorations (including arrows) for Connectors. It uses the characters from a TrueType font that has been installed in your copy of Squeak. Squeak comes with three TrueType fonts installed (the BitstreamVera family). You may want to install another font (like Wingdings) to have more choices for end decorations.

When you have chosen a shape to use as an end decoration, the "sample" button just shows you a sample of what a connector would look like with that shape on its end.

You can drag the green squares at the ends and middle of the sample, but the sample itself is not an object that can be used.

(The "Make Morph" button uses the selected shape to make a stand-alone Curve object that you can use by itself).

The sample is helpful to do things like setting the arrow scales or attachment points. When the sample looks like you want it to, you can then use the "Install" button to give a name to the end decoration you've chosen.

Now you can close the Arrow Editor.

To use the end decoration you've just defined:

- get a connector from the Objects tool or a flap. - move the mouse over one of the ends of the connector - and use your middle or right mouse button (or hold down Alt or Cmd while clicking on an end) to bring up the Connector's menu. - You should see a menu with "end..." and "new arrow" as its last items. - click on "new arrow". A little window called "Arrows" will appear. - use the "Prev" or "Next" buttons in that window, or search from its menu until your new arrow is being shown. - choose OK and that arrow will be used on that end of the Connector.
