Return value based on event in python -


i need value calculated calculate function being called once event being fired on_release function. value outside class.

class annotate(object):     def __init__(self,diff):         self.differnce = diff         self.x0 = none         self.y0 = none         self.x1 = none         self.y1 = none         self.ax = plt.gca()         self.ax.figure.canvas.mpl_connect('button_press_event', self.on_press)         self.ax.figure.canvas.mpl_connect('button_release_event', self.on_release)      def on_press(self, event):         print 'press'         self.x0 = event.xdata         self.y0 = event.ydata         # return x0,y0      def on_release(self, event):         print 'release'         x1 = event.xdata         y1 = event.ydata         self.calculate(int(self.x0), int(self.y0), int(x1), int(y1))      def calculate(self, a, b, c, d):         print a, b, c, d         print self.differnce         sum = 0         count = 0         in range(a, c):             j in range(b, d):                 sum = sum + self.differnce[i,j]                 count = count+1         print sum         print count         if (sum==0):             if(count==0):                 print "try again"         else:             return sum/count  = annotate(diff) print

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
