cocoa - How to reference/open a window in Objective-c -


i need reference single window in app. if tick off "visible @ launch" shows up.

i keep seeing code following doesn't make sense. how self know window in nib file if not declared anywhere in interface? 

nswindow *window = [self window];

when run in applicationdidfinishlaunching, error:

no visible @interface 'appdelegate' declares selector 'window'

that makes sense, because no interface declared. yet how window loading automatically when 'visible @ launch' ticked?

my end goal need reference window , change level, i.e.

[window setlevel:nsfloatingwindowlevel];

please help?

the short answer is:

in appdelegate.h, declare "window" property:

 @property (strong) iboutlet nswindow* window;

in mainmenu.nib, connect main window "window" property of "appdelegate":

right-click on "appdelegate" object, click on widget next "window" property , drag window.

your "appdelegate" instance have "window" property, , assigned main window.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
