[squeakland] How to get a button to start painting

[Harness, Kathleen]

Steve,
Also, there is a way to detach the Halo handles and they still function but I can't remember exactly and didn't rediscover it in a hurried 5 minutes of keystroke combo clicks. I bet someone knows and will tell.

It is one of those examples that prove that every-thing-is-an-object.
On that topic, my young students are realizing that they can deconstruct and modify things like the All Scripts button; a gateway moment that leads to other experiments.

Kathleen,

Nice!  After all this time I am still learning new things about Etoys.

Hi Luis,
The attached project works with repaint buttons for two objects, more as needed.
Regards,
Kathleen

Hi,

If I understood your problem correctly, I think you can create an empty drawing and in the button script put something like this:

[ Sketch | copy | do menu item | repaint ]

So now, when you click the button you'll be repainting a copy of the original sketch and you can use it many times.

Cheers,
Richo

Dear friends,
I've a student developping a project to teach some basic math concepts. In her proposal, it's needed a button to start drwaing things using the etoys paintbox. Because it will be needed several times I can't recommend the "do menu item" "repaint".
Anny suggestiont to help solve this problem will be appreciated.

Luis
