Question

i want to run my view based window application with ticker.i have code for ticker but it is in cocoa..
so how can i integrate cocoa application in my project.?
this is TickerView.h file
#import <Cocoa/Cocoa.h>
#interface TickerView : NSTextView {
#private
NSTimer *mTimer;
double mOffset;
}
- (NSString *)stringValue;
- (void)setStringValue:(NSString *)stringValue;
- (void)appendString:(NSString *)s;
- (IBAction)startAnimation:(id)sender;
- (IBAction)stopAnimation:(id)sender;
#end
This is TickerView.m file
#import "TickerView.h"
#implementation TickerView
- (id)initWithFrame:(NSRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self setEditable:NO];
NSTextContainer *container = [self textContainer];
[container setWidthTracksTextView:NO];
[container setContainerSize:NSMakeSize(99999., frame.size.height)];
}
return self;
}
- (void)dealloc {
[self stopAnimation:self];
[super dealloc];
}
- (void)drawRect:(NSRect)rect {
[super drawRect:rect];
}
- (NSString *)stringValue {
return [[self textStorage] string];
}
- (NSDictionary *)standardAttributes {
return [NSDictionary dictionaryWithObjectsAndKeys:
[NSFont fontWithName:#"Helvetica" size:([self frame].size.height * 0.8)], NSFontAttributeName,
[NSColor redColor], NSForegroundColorAttributeName,
nil];
}
- (void)setStringValue:(NSString *)s {
NSRange fullRange = NSMakeRange(0, [[self textStorage] length]);
NSAttributedString *sa = [[[NSAttributedString alloc]initWithString:s attributes:[self standardAttributes]] autorelease];
[[self textStorage] replaceCharactersInRange:fullRange withAttributedString:sa];
}
- (void)appendString:(NSString *)s {
NSRange endRange = NSMakeRange([[self textStorage] length], 0);
NSAttributedString *sa = [[[NSAttributedString alloc]initWithString:s attributes:[self standardAttributes]] autorelease];
[[self textStorage] replaceCharactersInRange:endRange withAttributedString:sa];
}
- (IBAction)startAnimation:(id)sender {
if (nil == mTimer) {
mTimer = [NSTimer scheduledTimerWithTimeInterval:1./60. target:self selector:#selector(step:) userInfo:nil repeats:YES];
}
}
- (IBAction)stopAnimation:(id)sender {
if (mTimer) {
[mTimer invalidate];
[mTimer release];
mTimer = nil;
}
}
- (void)step:(NSTimer *)timer {
mOffset -= 2; // pixels per tick
[self setTextContainerInset:NSMakeSize(mOffset, 0)];
[self setNeedsDisplay:YES];
}
#end

You can't just drop it in (as far as I know).
I'd do it by changing your inheritance from NSTextView to UILabel and reading the docs for that. then just work through the code bit by bit until it works ;)
