gridview - Process after grid was loaded completely using ExtJS -

-

i using extjs load data grid, , want add additional processes after data put on grid completely.

my context is, after data put on grid, check rows, , mark of them disabled based on specified condition , put tooltip row (explain why disabled). tried use 2 events: 'afterrender' of grid, , 'load' of grid's store, did not work.

because grid's 'afterrender' fired when first grid initialization, not concern data load. store's 'load' fired when data prefetch store (not render on screen), cannot row <div> style disabled.

so, event detect when data loaded , rendered on grid? , how can implement requirement?

i think task don't need wait until grid loaded rather use viewconfig option grid panel configure how display rows:

viewconfig: {    getrowclass: function(r) {       if (r.get('disabled'))          return 'disabled-class';       else           return '';    } }

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

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...
