cocoa - Make NSView in NSPanel first responder without key window status -

-

is possible give nsview inside nspanel first responder status without giving nspanel key window status (making main application window resign key)?

thanks.

well, ended figuring 1 out, took lot of research i'll post details here in case else runs same problem. first of all, few basics:

  1. it's impossible have 2 windows key @ same time
  2. it's possible fake window thinking it's key overriding -iskeywindow won't give views contained in window first responder status.

my scenario:

i added child window containing nstableview main application window (the reason irrelavant). child window nspanel nsborderlesswindowmask. wanted give nstableview first responder status without making panel key window because took away focus main window (and whole point of child window illusion make child window part of main window).

the first thing tried fooling table view thinking inside key window overriding iskeywindow return yes. made table view draw if first responder, still did not give first responder status.

the solution:

so default, nsborderlesswindowmask not allow window become key. make table view first responder, window had key overrode canbecomekeywindow in borderless window subclass return yes. this, of course, took away key status main window, 1 of things wanted avoid. fix this, subclassed main window , overrode following methods:

- (bool)ismainwindow {     return yes; }  - (bool)iskeywindow {     return ([nsapp isactive]) ? yes : [super iskeywindow]; }

this subclass checks if application active, , if is, returns yes no matter window active in application, main window behave if still key. sort of gives illusion can have multiple windows key @ same time , enables shift key window status window without losing on main window. hope helps!

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
