cocoa - Creating an NSWindow that floats over all other windows in the app but not over windows from other apps -

-

i trying make nswindow show on top in application don't want float on other apps have become active. have tired following code makes window float on other applications:

nsrect frame = nsmakerect(100, 100, 800, 800); mywindow  = [[nswindow alloc] initwithcontentrect:frame                                                 stylemask:nsborderlesswindowmask                                                   backing:nsbackingstorebuffered                                                     defer:no]; [mywindow setlevel:nsfloatingwindowlevel  ]; [mywindow setbackgroundcolor:[nscolor bluecolor]]; [mywindow makekeyandorderfront:nsapp];

i have tried of constants listed in nswindow documentation , did not find 1 make nswindow float on other windows in not other windows of other active apps. not possible?

there's no built-in support that. might consider setting window hide on deactivate.

alternatively, can have window controller observe nsapplicationwillresignactivenotification , nsapplicationdidbecomeactivenotification notifications , adjust window level. when app resign active status, set window level normal. when becomes active again, set float. (if window controlled app delegate, can in -applicationwillresignactive: , -applicationdidbecomeactive: delegate methods.)

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
