Everything Quincey says is right.
No surprise there then.
However, subclassing NSTableView and NSTextView to provide intrinsicContentSize
does not have to be awful for a simple scenario (though these sort of things
can descend into awfulness sometimes…)
Obviously you need to obtain raw NSTableView and NSTextView instances sans
NSScollView containers.
NSTableView might go something like this:
@implementation TSTableView
- (NSSize)intrinsicContentSize
{
NSSize size = [super intrinsicContentSize];
NSInteger nr = [self numberOfRows];
CGFloat rh = [self rowHeight];
CGFloat ih = [self intercellSpacing].height;
size.height = rh * nr + ih * MAX(nr, 1);
return size;
}
For textviews I do something like:
@interface TSTextView : NSTextView
// primitives
@property (assign, nonatomic) CGFloat borderOffsetX;
@property (assign, nonatomic) CGFloat borderOffsetY;
@end
@implementation TSTextView
#pragma mark -
#pragma mark Life cycle
- (instancetype)initWithFrame:(NSRect)frameRect textContainer:(nullable
NSTextContainer *)container
{
self = [super initWithFrame:frameRect textContainer:container];
if (self) {
[self commonInit];
}
return self;
}
- (nullable instancetype)initWithCoder:(NSCoder *)coder
{
self = [super initWithCoder:coder];
if (self) {
[self commonInit];
}
return self;
}
- (void)commonInit
{
_borderOffsetX = 1;
_borderOffsetY = 3;
self.usesFontPanel = NO;
self.usesFindPanel = NO;
}
#pragma mark -
#pragma mark Auto layout
- (NSSize)intrinsicContentSize
{
NSTextContainer* textContainer = [self textContainer];
NSLayoutManager* layoutManager = [self layoutManager];
[layoutManager ensureLayoutForTextContainer: textContainer];
NSSize size = [layoutManager usedRectForTextContainer: textContainer].size;
return NSMakeSize(NSViewNoInstrinsicMetric, size.height);
}
#pragma mark -
#pragma mark Accessors
- (void)setString:(NSString *)string
{
[super setString:string];
[self invalidateIntrinsicContentSize];
}
#pragma mark -
#pragma mark Text change notifications
- (void)didChangeText
{
[super didChangeText];
[self invalidateIntrinsicContentSize];
}
#pragma mark -
#pragma mark Focus ring
- (void)drawFocusRingMask
{
if (self.editable) {
NSRectFill(self.focusRingMaskBounds);
}
}
- (NSRect)focusRingMaskBounds {
NSRect r = [self bounds];
return NSMakeRect(r.origin.x - self.borderOffsetX, r.origin.y -
self.borderOffsetY, r.size.width + self.borderOffsetX * 2, r.size.height +
self.borderOffsetY * 2);
}
