cocoa - NSTextFieldのLineFragmentPadding

Question

NSTextFieldが使用している行フラグメントのパディングを知るにはどうすればよいですか？

Answer 1

-lineFragmentPaddingに使用できますNSTextField's textContainer。このような：

float lineFragmentPadding = [textContainer lineFragmentPadding];

例えば：

NSSize textFieldSize = [textFieldOutlet frame].size;
NSTextStorage *textStorage = [[[NSTextStorage alloc] initWithAttributedString:[textFieldOutlet attributedStringValue]] autorelease];
NSTextContainer *textContainer = [[[NSTextContainer alloc] initWithContainerSize:NSMakeSize(textFieldSize.width, textFieldSize.height)] autorelease];
NSLayoutManager *layoutManager = [[[NSLayoutManager alloc] init] autorelease];

[layoutManager addTextContainer:textContainer];
[textStorage addLayoutManager:layoutManager];

[layoutManager glyphRangeForTextContainer:textContainer];

float lineFragmentPadding = [textContainer lineFragmentPadding];
NSLog(@"Padding: %f", lineFragmentPadding);
