java - not able to move mouse and capture gesture using Leapmotion controller in scala -

-

i'm trying use leapmotion jar replicate mouse motion gesture , hand movement, i've created 2 methods 

def executegesture(gesture: gesture) = {      val robot = new robot();     gesture.match {     case gesture.type.type_circle => {         println("circle is")         val circle = new circlegesture(gesture);          if (circle.pointable().direction().angleto(circle.normal()) <= math.pi / 4) { // clockwise if angle less 90 degrees             //              robot.mousepress(inputevent.button1_mask)             //              robot.mouserelease(inputevent.button1_mask)             //              robot.mousepress(inputevent.button1_mask)             //              robot.mouserelease(inputevent.button1_mask)          } else {          }     }     case gesture.type.type_swipe => {         val swipe = new swipegesture(gesture)          if (swipe.direction().getx() > 0) {             println("swipe right")          } else {             println("swipe left ")             robot.keypress(keyevent.vk_alt);             robot.keypress(keyevent.vk_f4);             robot.keyrelease(keyevent.vk_alt);             robot.keyrelease(keyevent.vk_f4);         }     }     case gesture.type.type_screen_tap => {         val screentap = new screentapgesture(gesture)         println("screen tap " + screentap.id())     }     case gesture.type.type_key_tap => {         val keytap = new keytapgesture(gesture)         println("key tap " + keytap.id())         robot.mousepress(inputevent.button1_mask)         robot.mouserelease(inputevent.button1_mask)     }     case _ => println("something else!!. .")     } }  def executemovement(frame: frame) {     val robot = new robot             val finger = frame.fingers().get(0)             val gd = graphicsenvironment.getlocalgraphicsenvironment().getdefaultscreendevice()             val xwidth = gd.getdisplaymode().getwidth()             val xheight = gd.getdisplaymode().getheight()              val tipvelocity = finger.tipvelocity().magnitude().toint             val position = finger.tipposition()              if (tipvelocity > 2) {                 prevpoint.x = nextpoint.x                         prevpoint.y = nextpoint.y                          val mousex = (xwidth + math.round(position.getx() * (xwidth / 100)))                         val mousey = ((xheight - (0.0f + position.gety() * 4.0f - xheight / 5))).toint                          nextpoint.x = mousex                         nextpoint.y = mousey                          val diffx = (prevpoint.x - nextpoint.x).abs                         val diffy = (prevpoint.y - nextpoint.y).abs                          if ((diffx > 4) & (diffy > 4)) {                             robot.mousemove(nextpoint.x, nextpoint.y)                             //        movemouse(prevpoint.x, prevpoint.y, nextpoint.x, nextpoint.y, 200, 30)                         }             } }

executemovement moves mouse in direction of hand, when comment out executemovement, executegesture recognizes gestures, when run both these methods, not detect key_tap , screen_tap events. . , i'm not able understand reason behind it

i suspect skipping frames when run both functions. if onframe handler doesn't return enough, leap motion software skip frames until done. screen , keytap gestures appear in single frame, easy miss them if code dropping frames. way around save reference last frame code processed , pass frame.gestures(sinceframe) function. gives gestures objects have been generated between sinceframe , current frame.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

java - What is the difference between String. and String.this. ? -

this question has answer here: meaning of .this , .class in java 2 answers i'll straight point. im still learning bit of syntax , want know difference between code is code a: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.valueof(i))); } } please ignore fact i undeclared, not lost. code b: public class buttonz extends jbutton{ public buttonz(){ settext(new string(string.this.charat(i))); } } what don't yet understand difference in typing string.this , string. i under assumption when use dot operator on class accessing it's static methods(and/or variables if they're not hidden). i have studied little bit , have concluded when using string. accessing string static methods.. when using string.this. i'm accessing methods class buttonz extendi...
