Question

对整个可可/离岸价格来说,我是新鲜的(但C/C++的年份是*nix)。

I m试图创建基本可可申请,填满NSOpenGLView。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

和钦克。 h

@interface chinkView : NSOpenGLView {

    NSWindow *window;

}


@property (assign) NSWindow *window;


@end

我有一个单一的轴心。

https://skitch.com/cront/ri625/chinkxib

where chink View is set as delegate for Window and File Owner.

我错过了错误(甚至在申请最终启动之前),我的理解是,它试图在窗户前即刻出现公开观点(尽管我大概错)。

我想的是解决这一问题,即创造窗口,在其中树立开放的观点。一旦完成这项工作,我绝对没有撰写利比里亚武装部队的问题(如我说过的那样,我知道C++),但所有这支国家武装部队的炮火都与我无关。

我不问,为什么在SDL/GLUT的答复中你没有这样做。这部法典就是要恰当地创造窗口。

因此,我放弃了这一做法。

• 确定长途,并改为:

chink.mm

#import <Cocoa/Cocoa.h>
#import <OpenGL/OpenGL.h>
#import <OpenGL/gl.h>
#import <OpenGL/glu.h>

#import "chink.h"


@implementation chinkNS

- (id)initWithFrame:(NSRect)frameRect
{
    NSOpenGLPixelFormat * pixelFormat = [[NSOpenGLPixelFormat alloc] initWithAttributes:(NSOpenGLPixelFormatAttribute[]) {
        NSOpenGLPFAWindow,
        NSOpenGLPFADoubleBuffer,
        NSOpenGLPFADepthSize, 32,
        nil
    }];
    if(pixelFormat == NULL)
        NSLog(@"pixelFormat == NULL");
    [pixelFormat autorelease];

    self = [super initWithFrame:frameRect pixelFormat:pixelFormat];
    if(self == NULL) {
        NSLog(@"Could not initialise self");
        return NULL;
    }

    [[self openGLContext] makeCurrentContext];
    [self initGL];

    return self;
}

- (void)awakeFromNib
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(windowWillMiniaturize:) name:NSWindowWillMiniaturizeNotification object:[self window]];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(windowDidMiniaturize:) name:NSWindowDidMiniaturizeNotification object:[self window]];

    animationTimer = [NSTimer scheduledTimerWithTimeInterval:1/60.0 target:self selector:@selector(timerFired) userInfo:NULL repeats:YES];
    [[NSRunLoop currentRunLoop] addTimer:animationTimer forMode:NSEventTrackingRunLoopMode];
    [[NSRunLoop currentRunLoop] addTimer:animationTimer forMode:NSModalPanelRunLoopMode];
    lastTime = [[NSDate date] timeIntervalSince1970];
}

- (void)drawRect:(NSRect)frame
{

    NSLog(@"Chink is up and running. Let s do this thing!");

    glClearColor(0.0, 0.0, 0.0, 0.0);
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0, 1.0, 1.0);
    glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0); 
    glFlush();

    [self drawGL];
    [[self openGLContext] flushBuffer];



}

#pragma mark OpenGL

- (void)initGL { }

- (void)reshapeGL { }

- (void)drawGL { }

- (void)animate:(float)dt { }

#pragma mark Event Handling

- (void)timerFired
{
    NSTimeInterval currentTime = [[NSDate date] timeIntervalSince1970];
    [self animate:currentTime-lastTime];
    lastTime = currentTime;
}


#pragma mark Loose ends

- (void)setFrame:(NSRect)frame
{
    [super setFrame:frame];
    [self reshapeGL];
}

// To get key events
- (BOOL)acceptsFirstResponder
{
    return YES;
}


@end

和钦克。 h

@interface chinkNS : NSOpenGLView
{

    NSTimer * animationTimer;
    NSTimeInterval lastTime;

}

- (void)initGL;
- (void)reshapeGL;
- (void)drawGL;
- (void)animate:(float)dt;

@end

.xib的同样情况,但标准NSView除外,该词贬低了我的公开观点。

我希望像上一样建立一个更简单、更强的立法机构,但你能够赢得大家的胜利。

闭门会议。
