JSCTabletView

superclass: JSCAbstractUserView (!!)

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

NOTE : Currently Mac OS X only

to use, install the jni library:

$ cp JNITablet/build/libJNITablet.jnilib /Library/Java/Extensions/

or make a symbolic link

$ ln -s <absolutePathToSwingOSC>/JNITablet/build/libJNITablet.jnilib /Library/Java/Extensions/

action - dragging the mouse inside the view

args: view, x, y, pressure, tiltx, tilty, deviceID, buttonNumber, clickCount, absoluteZ, rotation,

absoluteX, absoluteY, buttonMask, tanPressure;

mouseDownAction

args: view, x, y, pressure, tiltx, tilty, deviceID, buttonNumber, clickCount, absoluteZ, rotation,

absoluteX, absoluteY, buttonMask, tanPressure;

mouseUpAction

args: view, x, y, pressure, tiltx, tilty, deviceID, buttonNumber, clickCount, absoluteZ, rotation,

absoluteX, absoluteY, buttonMask, tanPressure;

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 : -1 (max. left) ... +1 (max. right)

tiltY : -1 (max. down) ... +1 (max. up)

deviceID - All tablet-pointer events generated in the period between the device entering

and leaving tablet proximity have the same device ID. Therefore, when working

with multiple tablets / mice, you can match actions by looking at the deviceID.

buttonNumber - 0 left, 1 right, 2 middle wheel click. see also buttonMask below.

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. Used for example on the "4d mouse", and the "art marker". Note: on Mac OS X 10.4.11 using an Intuos3 tablet with Art Marker, the returned value must be multiplied by 1024 to actually obtain degrees (bug?).

these additional ones are delivered only in SwingOSC:

absoluteX - the absolute horizontal pen position on tablet (in tablet-native high-resolution)

absoluteY - the absolute vertical pen position on tablet (in tablet-native high-resolution)

buttonMask - a flag mask of all buttons on the pen / tablet. you can extract each button's state

using a bitAnd: buttonMask.bitAnd( 1 << n ) where n = 0, 1, 2, ...

tanPressure - Tangential pressure is also known as barrel pressure.

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.

tiltx.round( 0.01 ), tilty.round( 0.01 ), clickCount, absoluteX, absoluteY, absoluteZ,

rotation.round( 0.01 ), buttonMask );

Detecting Proximity (SwingOSC only)

proximityAction_( func )

func will be called with the arguments view, entering, deviceID, pointingDeviceType, systemTabletID, pointingDeviceID, tabletID, uniqueID:

view

true to indicate that a pointing device is entering the proximity of its tablet and false when it is leaving it.

entering

true to indicate that a pointing device is entering the proximity of its tablet and false when it is leaving it.

deviceID

All tablet-pointer events generated in the period between the device entering and leaving tablet

proximity have the same device ID. Therefore, when working with multiple tablets / mice, you can

match actions by looking at the deviceID.

pointingDeviceTypes

0 NSUnknownPointingDevice

1 NSPenPointingDevice

2 NSCursorPointingDevice

3 NSEraserPointingDevice

systemTabletID

If multiple tablets are connected to the system, the system-tablet ID is incremented for each subsequent one.

If there is only one tablet device, its system-tablet ID is zero.

pointingDeviceID

This index is significant for multimode (or Dual Tracking) tablets that support multiple concurrent pointing devices;

the index is incremented for each pointing device that comes into proximity. Otherwise, zero is always returned.

tabletID

Returns the USB model identifier of the tablet device associated with the receiver.

uniqueID

Also known as tool ID, this is a unique number recorded in the chip inside every pointing device.

The unique ID makes it possible to assign a specific pointing device to a specific tablet.

(

w = JSCWindow.new;

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

t.background = Color.white;

w.acceptsMouseOver = true;

w.front;

t.proximityAction = { arg view, entering, deviceID, pointingDeviceType, systemTabletID, pointingDeviceID, tabletID, uniqueID;

var what = if( entering, "enter", "exit " );

("%: deviceID % pointingDeviceType % systemTabletID % pointingDeviceID % tabletID % uniqueID %\n").postf(

what, deviceID, pointingDeviceType, systemTabletID, pointingDeviceID, tabletID, uniqueID );

};

)

JSCTabletView is a also a user view... (SwingOSC only)

(

var x = 150, y = 150, pressure = 0, tiltx = 0, tilty = 0, rota = 0, colr = Color.white;

w = JSCWindow.new;

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

t.background = Color.white;

w.front;

f = { arg view, argX, argY, argPressure, argTiltX, argTiltY, deviceID, buttonNumber,

clickCount, absZ, argRota;

x = argX; y = argY; pressure = argPressure;

tiltx = argTiltX; tilty = argTiltY;

rota = argRota * 1024; // * 1024 for Art Marker...

view.refresh;

};

t.drawFunc = { arg view;

JPen.fillColor = colr;

JPen.fillRect( view.bounds.moveTo( 0, 0 ));

JPen.translate( x, y );

JPen.width = pressure * 10 + 0.5;

JPen.rotate( rota * pi / 180 );

JPen.skew( tiltx, tilty );

JPen.strokeOval( Rect( -100, -100, 200, 200 ));

JPen.line( -100 @ 0, 100 @ 0 );

JPen.line( 0 @ -100, 0 @ 100 );

JPen.stroke;

};

t.mouseDownAction = f;

t.action = f;

t.mouseUpAction = f;

t.proximityAction = { arg view, entering, deviceID, pointingDeviceType;

colr = if( entering, { Color.hsv( pointingDeviceType / 4, 0.5, 1.0 )}, Color.white );

view.refresh;

};

)

Here's a variation: make the above example respond only to a particular pen tools. For this, you need a pen that fires proximity actions and you need to know the pen's uniqueID (see above "Detecting Proximity"). For example, my Art Marker has ID 127926421:

(

var filterUniqueID = 127926421; // put your own ID here

var filterDeviceID = -1;

var fProx, fAction;

fProx = t.proximityAction;

t.proximityAction = { arg view, entering, deviceID, pointingDeviceType,

systemTabletID, pointingDeviceID, tabletID, uniqueID;

if( uniqueID == filterUniqueID, {

filterDeviceID = deviceID; // now t.action only reacts to events from this deviceID

fProx.value( view, entering, deviceID, pointingDeviceType );

});

};

fAction = t.action;

f = { arg view, x, y, pressure, tiltX, tiltY, deviceID, buttonNumber,

clickCount, absZ, rota;

if( deviceID == filterDeviceID, {

fAction.value( view, x, y, pressure, tiltX, tiltY, deviceID, buttonNumber,

clickCount, absZ, rota );

});

};

t.mouseDownAction = f;

t.action = f;

t.mouseUpAction = f;

)
