say have standard cocoa application call foo.app (like 1 choosing new project > cocoa application in xcode), if open app via terminal using: open foo.app/ then see foo's name on status bar top , window in focus, in front of other apps. if instead directly call terminal executable buried in .app folder, like: foo.app/contents/macos/foo nothing appears happen. on inspection app has indeed opened not in focus (the terminal still is), have find on dock or find window. is there way foo application make sure in focus when run? if run via executable described above? your app can "steal focus" calling [[nsapplication sharedapplication] activateignoringotherapps:yes]; see nsapplication docs more info.

i new iphone app development. have been trying draw border table in iphone app. of posts see how remove seperation lines between cells or change colors or add background. i tried following - (void)viewdidload { [super viewdidload]; self.tableview.layer.border = 1; } however, says border not attribute. it great if me out in this. perhaps mean you'd display table in 'grouped' style, adds border?

i'm in process of writing wordpress plugin creates page in admin area, executing frontend code. the code below throws nice fatal error: using $this when not in object context error. rather mystifying, variable called inside class. maybe i'm not following intended wordpress plugin structure functions , classes, conceptual code below created using relevant entries on plugin development in wordpress codex. could explain why error triggered, because when create instance of class outside of wordpress codebase fine. if (!class_exists("myclass")) { class myclass { var $test = 'test variable'; public function index() { //index code } public function add() { echo $this->test; } } } add_action('admin_menu', 'my_plugin_menu'); function my_plugin_menu() { add_menu_page('my plugin', 'my plugin', 'manage_options', 'my-plugin', array('myclass', 'index'));...

i trying make dimensioned vector class boost-units so, //vector constructed vec<si::length> v(10, 1.0*si::metre); template<typename dimension> class vec { public: //constructor setting values q. vec(const size_t, const boost::units::quantity<dimension> q) //etc } it works fine except operator*= , operator/= element wise multiplication , division. since these not change dimension, make sense when multiplying/dividing dimensionless quantity: struggling find arbitrary dimensionless quantity not locked specific system (e.g. si or cgs units). i want like, /** multiply dimensionless vector. */ vec<dimension>& operator*=(const vec<boost::units::dimensionless_type>& b); or perhaps metaprogramming magic (i notice boost::units::is_dimensionless exists, have no idea how use not versed in general metaprogramming techniques) template<typename dimension> template<typename a_dimensionless_type> vec<dimension...

in response this question jquery effects, thought using callback argument .fadein( 500, my_function ) . while in principle, viable idea, have no clue (and neither has jquery documentation :( ) if callback allowed recurse: function keep_animating(){ $("#id").fadein(500).fadeout(500, keep_animating ); } you add debugger breakpoint , test if stack size increases or not. :) however, since animations/fadings use settimeout/setinterval highly guess call depth not increase, i.e. it's not prone stack overflows.
