I want to use a MultiTouchXY with only one box.
First, I want the box to appear when I open my interface (it only appear after first touch).
Second: I want a button that center the box in the MultiTouchXY and send the values (0.5, 0.5).
What would be the functions?
Thanks in advance.
Is there any API documentation? I didn't find it.
Sorry for the delayed response... in general, all widgets respond to the setValue message. For multitouchxy this takes the form:
myWidget.setValue(0, .5, .5); // touchNumber, x value, y value
Hope this helps... there is general documentation available at http://www.charlie-roberts.com/Control, although I'm not sure if this specific function is covered. - Charlie
"multi.setValue(1, .5, .5);" works... but does not center the box. It locate at 60% X, %60 Y, aproximatly. And it doesn't send the Value.
(the touchNumber for only one box is 1, not 0)
Well, the only way to take the box to the "supposed" center and send the value is:
"ontouchstart": "multi.setValue(1, .5, .5); oscManager.sendOSC(['/multi/1', 'ff', 0.5, 0.5]);",
... because setValue() does not send anything.
"Supposed" because Control is still calculating wrong the center of the multiTouchXY box.
I have a 800x450 tablet , using landscape orientation.

I tried in LG Pecan phone and it's the same "centering" problem.
Looks like the multi touch is centering the top left of the box.
I'm getting the control message as it is centered with the "centrar" button but if I touch the control without moving it I get values x: 0.623... y: 0.549...
A workaround would be to find the offset (looks like it's around .425 for both axis) and center to there.

It works!
Thanks, Arblick_spule.
My pleasure. Overriding the update method for the widget would be a better way to do things but that's a whole other adventure. ;)
I want to syncronize a Control slider with PureData slider. I send to Control:
/control/runScript volumen_mus.setValue($1)
But this makes Control sending the same value AGAIN to PureData. Then, the slider is crazy.
Can't I set the value in Control slider and finish there?
