flex, change the button image when mouse over/out -

-

with following code, have implemented image change when mouse hover button. image name hardcoded, specified in style. how can make parameterized? want reuse small utility image name input parameter. image used(14 images in case) included in flex project. using flex 3

<mx:style>       .mycustombutton {         upskin: embed(source="jjyxfx.png");         overskin:embed(source="cwgl.png");        downskin: embed(source="cwgl.png");      } </mx:style>  <mx:button y="0" width="105" height="107" fillalphas="[1.0, 1.0, 1.0, 1.0]" x="0" fillcolors="[#3aa2d9, #3aa2d9]" stylename="mycustombutton" usehandcursor="true" buttonmode="true"/>

i don't believe can't parameterize css styles; you'll have set styles via actionscript:

public function setstylesonbutton(upskinvalue:string,overskinvalue:string,downskinstyle:string):void{   mybutton.setstyle('upskin',upskinvalue);   mybutton.setstyle('overskin',overskinvalue);   mybutton.setstyle('downskin',downskinstyle); }

make sure button has id can access in actionscript:

<mx:button id="mybutton" y="0" width="105" height="107" fillalphas="[1.0, 1.0, 1.0, 1.0]" x="0" fillcolors="[#3aa2d9, #3aa2d9]" stylename="mycustombutton" usehandcursor="true" buttonmode="true"/>

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...
