actionscript 3 - Loading and unloading fonts for multilingual Flex app -

-

my flex app allows people enter text. there's broad selection of fonts choose from. because multi-lingual app, of fonts (e.g. chinese) large indeed - big embed fonts.

i know can load fonts @ runtime via stylesheets - plan people select font (a small wait while font loads not problem). want able unload fonts again, app doesn't consume huge amount of memory if people select 1 font , another.

i can't see way it, though. can load fonts @ runtime, not unload them. ideas?

i did see this question on mentions loading fonts part of module - 1 font per module, guess. advantage being modules can unloaded. then, font isn't accessible outside module, questioner points out. seems dead end.

if it's not possible, - sadly - accept answer shows me it's impossible, more useful alternative strategy! must pretty common scenario people have run before...

as intuition suggests, relatively common scenario flex developers - there's got solution!

as have suggested, compile stylesheets modules fonts embedded in each (for chinese, suggest @ specifying unicode ranges if possible save on font size: http://renaun.com/blog/2011/10/flash-embed-font-unicode-range-generator/).

there 3 application domains can load modules parent app. take @ this: http://help.adobe.com/en_us/actionscript/3.0_programmingas3/ws5b3ccc516d4fbf351e63e3d118a9b90204-7e07.html. believe 2 out of 3 ways allows use resources module. easiest load same application domain - meaning assume classes in module same parent's.

make sure build system compiling modules same version of sdk parent application. otherwise, run actionscript runtime errors marshalling classes.

finally, how profiling application garbage collection? using flash builder's built-in profiler? forcing garbage collection on flex app annoying (from remember, must call system.gc() twice or weird voodoo magic that).

c# - Copy ObservableCollection to another ObservableCollection -

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...
