I create MyImageView (from NSImageView) which must use MyImageCell (from
NSImageCell).
I put MyImageView in MyWindow with Interface Builder, creating an
NSImageView and setting its class to MyImageView.
In MyImageView.m I put:
@implementation MyImageCell
- (void)encodeWithCoder:(NSCoder *)aCoder {
[super encodeWithCoder:aCoder];
}
- (id)initWithCoder:(NSCoder *)decoder
{
if (self = [super initWithCoder:decoder])
{
...
}
return self;
}
...
@end
@implementation MyImageView
+ (void)initialize {
if (self == [MyImageView class]) {
[self setCellClass:[MyImageCell class]];
}
}
- (void)encodeWithCoder:(NSCoder *)aCoder {
[super encodeWithCoder:aCoder];
}
- (id)initWithCoder:(NSCoder *)decoder
{
if (self = [super initWithCoder:decoder])
{
[self setEnabled:YES];
[[self cell] setSelectable:YES];
[self setImageFrameStyle:NSImageFrameGrayBezel];
...
}
return self;
}
...
@end
Well: MyImageView is properly created, by its cell is still an
NSImageCell, and not MyImageCell.
Can you tell me why?
Besides if I call a public MyImageView's method with [NSApp
sendAction:@selector(anAction:) to nil] nothing happens ([NSApp
targetForAction:@selector(anAction:)] returns nil).
Why?
Thank you very much in advance,
best regards,
livio.
