如何在NSTextView中的光标处获取当前字体/字体大小？

Question

Clarification: First, cursor = the insertion point cursor, not the mouse cursor.

Ok, I would like to return the font / font size / font color wherever the cursor is in the NSTextView. I tried using attribute:atIndex:effectiveRange: , but I failed because I got my variables all mixed up. I think it is what I need. Some example code would just be appreciated, return ing the font. I think it will work the same for font size/color, I'll just have to substitute NSFontAttributeName for something else, right? Thanks in advance!

Answer 1

NSFont *font = [textView.textStorage attribute:NSFontAttributeName atIndex:textView.selectedRange.location effectiveRange:nil];

应该为所有人的名字而努力。

Answer 2

What have you tried?

NSTextView has a method selectedRanges which returns the current selection(s) - just one of zero-length if there is just an insertion point.

NSTextView also has a property textStorage which returns back the instance of NSTextStorage which holds the text. An NSTextStorage inherits from NSMutableAttributedString , which inherits from NSAttributedString , and that has methods to obtain the attributes of the text.

Combined those two and you have your answer.
