html5 - double buffering SVG in HTML -

-

i wonder better way simulate double buffering possibly complex svg. i'm reloading modified svg, , i'd rid of load delay. thinking of using 2 overlapped divs , toggle visibility after onload. there better alternative?

edit

now have implemented 2 svg instances in divs overlapped, style display toggling (block/none). worked in ff (nice, smooth morphing, initial display resulted in reduced area), chrome refuses me screenctm transform need syncing shapes position. guess problems (partial area render in ff, no render in chrome) related. i'm experimenting visibility:hidden instead.

edit

toggling visibility give acceptable results. far.

edit

i've found problem, make me here again helping hand: i'm using boostrap non svg related ui, , toolbar behaves strange: when switched visibility on 2^ div (initially hidden), no event arrives toolbar. switching again 1^, events ok.

i found using position:absolute or position:fixed same (for events problem, of course), , top:0 it's 'culprit'. using value > 0 let event flow, div goes invisible. intial question make sense: better method switch visibility? or hint on html structure? html looks like

<div class="row-fluid" style="height:800px;background-color:cyan"> <div id="flowchart" style="visibility:visible;width:100%;height:100%"></div> <div id="flowchart_x" style="visibility:hidden;width:100%;height:100%;position:absolute;top:0"></div> </div>

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...
