I've got an NSScrollView (added with IB) in my app. I've got an NSView
subclass that I am trying to add as the scrollView's documentView, but
I keep getting the following warning:
"Passing argument 1 of 'setDocumentView:' from incompatible pointer type."
Here's my code:
// scrollViewController.h
@class imageView;
@interface imageViewController : NSObject
{
IBOutlet id scrollView;
imageView *theImageView;
}
// scrollViewController.m
- (void)dealloc {
[theImageView release];
[super dealloc];
}
- (void)awakeFromNib {
theImageView = [[imageView alloc] initWithFrame:NSMakeRect(20,20,300,200)];
[scrollView setHasHorizontalScroller:YES];
[scrollView setHasVerticalScroller:YES];
[scrollView setScrollsDynamically:YES];
[scrollView setDrawsBackground:YES];
[scrollView setBackgroundColor:[NSColor colorWithCalibratedWhite:0.4
alpha:1.0]];
[scrollView setDocumentView:theImageView];
}
Does anyone have an insight into why I am getting this error? (The
NSView subclass never shows up in the window, by the way). Thanks.
