SCTabletView

superclass: SCView

An otherwise featureless view that receives extended wacom tablet data.  It can also be used with a normal mouse but with less resolution.

action - dragging the mouse inside the view

mouseDownAction

mouseUpAction

Each of the three actions are passed the following wacom tablet values:

view - the view

x - subpixel location in view

y - subpixel location in view

pressure - 0..1

tiltX - 0..1

tiltY - 0..1

deviceID - will be used to look up if the tip or the eraser is used

buttonNumber - 0 left, 1 right, 2 middle wheel click

clickCount - double click, triple click ...

most relevant for the mouseDown, but still valid for the dragged and mouseUp

absoluteZ - the wheel on the side of some mice

rotation - in degrees, only on the 4d mice 

If using a mouse (even a wacom) rather than a pen, the x and y will be integer pixel values, rather than subpixel floats.  Wacom stylus devices have higher resolution than the screen.  Pressure will be 1 for mouse down, 0 for mouse up.

Properties

clipToBounds - by default the x y values are clipped to the bounds of the view.

it set to 0, it is possible to drag from inside to outside the view, and the x y values will 

exceed the bounds accordingly.

(

w = SCWindow.new;

t = SCTabletView(w,Rect(40,40,300,300));

t.background = Color.white;

w.front;

t.mouseDownAction = { arg  view,x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation;

["down",x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation].postln;

};

t.action = { arg  view,x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation;

["dragging", x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation].postln;

t.background = Color(x / 300,y / 300,tiltx,pressure);

};

t.mouseUpAction = { arg  view,x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation;

["up",x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount,absoluteZ,rotation].postln;

};

)

Assign the same function to each action

(

w = SCWindow.new;

t = SCTabletView(w,Rect(40,40,300,300));

t.background = Color.white;

w.front;

f = { arg  view,x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount;

[x,y,pressure,tiltx,tilty,deviceID, buttonNumber,clickCount].postln;

t.background = Color(x / 300,y / 300,tiltx,pressure);

};

t.mouseDownAction = f;

t.action = f;

t.mouseUpAction = f;

An example using crucial library

(

Instr([\minimoog,\loose],{ arg freq=440,int1=5,int2 = -5,

ffreqInterval=0,rq=0.4,gate=0.0;

var p,c,d,f;

c=LFNoise1.kr(0.1,0.45,0.55);

d=LFNoise1.kr(0.1,0.45,0.55);

f=LFNoise1.kr(0.1,2);

p=Pulse.ar([ freq  * int1.midiratio + f , freq, freq * int2.midiratio - f],

[c,d,c],0.2);

RLPF.ar(Mix.ar(p),freq * ffreqInterval.midiratio,rq)

* EnvGen.kr(Env.adsr, gate, Latch.kr(gate,gate))

},#[

]);

p = Patch.new([ 'minimoog', 'loose' ],[

nil,nil,nil,nil,nil,

Sheet({ arg f;

p.topGui(f);

v = SCTabletView(f,Rect(0,0,200,200));

v.background = Color.white;

v.action = { arg view,x,y,pressure,tiltx,tilty;

p.args.at(1).value_( int.map( x / 200 ) ).changed;
