How to refer to Cocoa controls located in in the same NSWindow? -


i have nswindow nsview , nstextfield inside.

i'm using interface builder right now. have dropped 2 controls on default nswindow , subclassed nsview. i'm implementing -drawrect method nsview , need access content of nstextfield.

how refer instance of nstextfield method inside nsview ?

your nswindow (or should be) controlled window controller. in ib create outlet nstextfield in window controller. using outlet, can refer nstextfield:

in window controller .h file:

@property (strong) iboutlet nstextfield *mytextfield;

in window controller .m file:

@synthesize mytextfield;

from there can in controller:

[[self mytextfield] seteditable: no];

a point note not access controls in window directly window windows (and cocoa controls matter) statically stored in xib/nib file. access controls (ui elements) channelled through controllers (nswindowcontroller, nsviewcontroller) in turn capable of loading xib/nib files.

apple provides various samples in docs on how this.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
