actionscript 3 - Flash as3 - Create a variable from instance on click event -

-

i have whole bunch of buttons need have both mouse on effect toggle effect (on click) changes hue. have made functions each hue change , parts works quite well. sadly cant figure out how toggle function work how supposed to.

below code toggle button. works fine, except variable global instead of specific instance. therefor works if have 1 button. how can change use variable 1 button in focus?

thanks in advance!

var primary = false;  function clickon(e:mouseevent):void{      if (primary == false)     {             greenhue(e.target);             primary = true;     } else {             nohue(e.target);             primary = false;     } }

the best thing extend class used buttons , add functions it, buttons derive have idependant behavior want.

class coloredbutton extends button {     var primary = false;        public function coloredbutton() {         this.addeventlistener(mouseevent.click, clickon);     }      private function clickon(e:mouseevent):void {            if (primary == false)     {               greenhue(e.target);               primary = true;           } else {               nohue(e.target);               primary = false;           }       }      ...   }

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
