Line wrapping with the horizontal scroller remaining visible is supported.
The exception I was experiencing was a result of misconfiguring the NSTextView
- setHorizontallyResizable: for wrapped text.
The configuration below seems to work well but line wrapping does not seem to
be precise with very large amounts of text (eg: log files > 2MB)
when the horizontal scrollbar will become active even when wrapping is enabled.
This effect may or may not be influenced by the state of NSLayoutManager -
hasNonContiguousLayout.
- (void)setLineWrap:(BOOL)wrap
{
NSScrollView *textScrollView = [self enclosingScrollView];
NSSize contentSize = [textScrollView contentSize];
[self setMinSize:contentSize];
NSTextContainer *textContainer = [self textContainer];
if (wrap) {
[textScrollView setHasHorizontalScroller:YES];
[textContainer setContainerSize:NSMakeSize(contentSize.width,
CGFLOAT_MAX)];
[textContainer setWidthTracksTextView: YES];
[self setHorizontallyResizable: NO];
} else {
[textScrollView setHasHorizontalScroller:YES];
[textContainer setContainerSize:NSMakeSize(CGFLOAT_MAX,
CGFLOAT_MAX)];
[textContainer setWidthTracksTextView: NO];
[self setHorizontallyResizable: YES];
}
}
