flex - DataGrid edits label instead of data -

-

i have editable datagrid in flex, data full of numbers. columns have no special itemrenderer, labelfunction, returns number as-is if positive, puts in parentheses if negative, so

27.3 => "27.3" -27.3 => "(27.3)"

now, these cells editable. when try edit cell positive number, nothing wrong. if try edit negative number, starts editing (27.3) instead of editing -27.3. because of this, when edit done, labelfunction evaluated new value in parentheses(i.e., labelfunction called "(30.5)"), , converting number results in nan.

so, want know if can make datagrid edit data in dataprovider instead of label shows.

i hope clear condition. please ask if need clarification.

thank you.

is you're after?

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
