this may case of newb-swimming-upstream, but... in fxml file, 1 of attributes identifies controller. assuming controller , identified methods bound node during load (i.e., controller instance instantiated , methods bound listeners identified in fxml). is there way programmatically associate controller instance javafx node (e.g., tableview) created procedurally vice via fxmlloader? if understand correctly, want define controller instance in java code, instead of letting fxmlloader instantiate it. you can calling setcontroller on fxmlloader before call load() . note means must create fxmlloader instance , invoke instance load() method, , must not call static load(url) method: mycontroller controller = new mycontroller(); fxmlloader loader = new fxmlloader(getclass().getresource("path/to/fxml")); loader.setcontroller(controller); parent root = loader.load(); if use technique, must not use fx:controller attribute in root element of fxml file. no

i have thread looks this: public void run() throws interruptedexception { while(true) { string cururl = taskqueue.take(); ... } } i know can change true volatile variable, , set false when no longer need it, used throughout application, difficult tell when no longer needed. i wondering if having infinite loop have visible effect on performance of rest of android vm, if left in blocked state when app not running. edit 1: code starts thread start if not running. as taskqueue blocking queue, no. leaving thread running throughout application's life not cause noticeable effect. if taskqueue wasn't blocking would. application consume near whole core of processing power looping fast can. a blocking queue cause thread invoking method 'take' halt until there result available return. non-blocking queue return null or throw exception.

i trying build iphone application capabilities of searching yelp's database using api. have never used api before (i'm student- not professional development experience), need simple walkthrough on how pull data overall, filter, , authenticate myself data. i'd learn how save location's identifier plist app can store places user visited. appreciated. thank you! i found online, can't make sense of it. can explain? class yelpclient: bdboauth1requestoperationmanager { var accesstoken: string! var accesssecret: string! required init(coder adecoder: nscoder) { super.init(coder: adecoder) } init(consumerkey key: string!, consumersecret secret: string!, accesstoken: string!, accesssecret: string!) { self.accesstoken = accesstoken self.accesssecret = accesssecret var baseurl = nsurl(string: "http://api.yelp.com/v2/") super.init(baseurl: baseurl, consumerkey: key, consumersecret: secret); var token = bdboauthtoken(token: accesstoke

from question , know possible set screen size of each layout simulate smaller screen size on android tablet. how can set "global" screen size across whole app simulate smaller screen size? i have sony xperia z tablet (10"), , simulate 7" tablet resolution 768 x 1024. at top of layout file when viewing in android studio see button drop down second left top , looks 2 phones on top of each other. click on , should simulate either or can use geny motion , emulate phones resolution

i've got linear component of collision resolution down relatively well, can't quite figure out how same angular one. i've read, it's like... torque = point of collision x linear velocity . (cross product) tried incorporate example found code don't see rotation @ when objects collide. other fiddle works rudimentary implementation of seperating axis theorem , angular velocity calculations. here's i've come with... property definitions (orientation, angular velocity, , angular acceleration): rotation: 0, angularvelocity: 0, angularacceleration: 0 calculating angular velocity in collision response: var pivota = this.vector(bodya.x, bodya.y); bodya.angularvelocity = 1 * 0.2 * (bodya.angularvelocity / math.abs(bodya.angularvelocity)) * pivota.subtract(iscircle ? pivota.add(bodya.radius) : { x: pivota.x + boundsa.width, y: pivota.y + boundsa.height }).vcross(bodya.velocity); var pivotb = this.vector(bodyb.x, bodyb.y); bodyb.angularvelocity = 1 *
