NSOpenGLView 可可(再次)
我对 Cocoa/Objective-C 很陌生(但在 *nix 上有多年的 C/C++ 经验)。
我正在尝试创建一个充满 NSOpenGLView 的基本 Cocoa 应用程序。我有:
chink.mm
#import <OpenGL/gl.h>
#import "chink.h"
@implementation chinkView
@synthesize window;
- (void) applicationDidFinishLaunching : (NSNotification *)aNotification {
NSLog(@"Danger, Will Robinson! Danger!");
}
- (void) dealloc
{
[window release];
[super dealloc];
}
@end
和 chink.h
@interface chinkView : NSOpenGLView {
NSWindow *window;
}
@property (assign) NSWindow *window;
@end
我有一个 .xib 设置为
https://skitch。 com/cront/ri625/chinkxib
其中“chink View”被设置为窗口和文件所有者的委托。
我收到“无效的可绘制”错误(甚至在应用程序完成启动之前),据我了解,这意味着它试图在窗口之前实例化 opengl 视图(尽管我可能是错的)。
我想要的是创建窗口并在其中设置 opengl 视图这个问题的解决方案。完成此操作后,我编写 OGL 绝对没有问题(就像我说的,我了解 C++),但所有这些 NS 调用的垃圾对我来说都是陌生的。
我不是在寻找“为什么不在 SDL/GLUT 中这样做”的答案。只是让它正确创建窗口的代码。
I'm new to the whole Cocoa/Objective-C malarky (but have years of C/C++ on *nix).
I'm trying to create a basic Cocoa application that is filled with an NSOpenGLView. I have:
chink.mm
#import <OpenGL/gl.h>
#import "chink.h"
@implementation chinkView
@synthesize window;
- (void) applicationDidFinishLaunching : (NSNotification *)aNotification {
NSLog(@"Danger, Will Robinson! Danger!");
}
- (void) dealloc
{
[window release];
[super dealloc];
}
@end
and chink.h
@interface chinkView : NSOpenGLView {
NSWindow *window;
}
@property (assign) NSWindow *window;
@end
I have a single .xib set up like
https://skitch.com/cront/ri625/chinkxib
where 'chink View' is set as delegate for Window and File Owner.
I'm getting an 'invalid drawable' error (even before the application finished launching), which to my understanding means that it is trying to instantiate the opengl view before the window (although I'm probably wrong).
What I want is the solution to this problem of creating the window and setting the opengl view inside it. Once this is done I have absolutely no problem writing the OGL (like I said, I know C++) but all this NS calls gunk is alien to me.
I'm not looking for 'why don't you do it in SDL/GLUT' answers please. Just the code to make it create the window properly.

好吧,所以我放弃了这种方法。
走了很长的路,改为:
chink.mm
和 chik.h
.xib 中的设置相同,除了它是一个标准 NSView,它是我的 opengl 视图的子类。
我希望有一个像上面那样更简单、更优雅的设置,但你不可能赢得所有这些。
关闭。
Okay so I sacked off this approach.
Went the long route and changed to this:
chink.mm
and chink.h
The same settings in the .xib except that it is a standard NSView that subclasses my opengl view.
I was hoping for a simpler, more elegant set up as above but you can't win 'em all.
Closed.
