[MacRuby-devel] Quartz 2D Graphics problem

[Colin Thomas-Arnold]

You can certainly compile a group of stuff as a framework, and add that framework to your project, but I've never tried to just toss in .h/.m files and access them from macruby.

Can anyone touch on that?  I'm interested to hear what can be done there...


AFA translating your code into Obj-C...


Here's the short version:

self.context = [[NSGraphics currentContext] graphicsPort];



And here's the long version!


// the header file, YourClass.h

@interface YourClass : ParentClass

@property (assign, nonatomic) CGContextRef context;
// or void* instead of CGContextRef, but graphicsPort returns a CGContextRef

@end



// the implementation file, YourClass.m

#import "YourClass.h"

@implementation YourClass

@synthesize context;

- drawRect:(CGRect)rect
{
  self.context = [[NSGraphics currentContext] graphicsPort];
}

@end
