I have an NSTextTable in which each cell will contain the entire text of a
small RTF document. I want the user to be able to edit the document’s text in
the cell, including applying styles.
In this case, a “style" means an NSDictionary containing entries for
NSFontAttributeName, NSParagraphStyleAttributeName, and some custom attributes
that I need, but I think the layout manager will ignore.
When I go to apply a style to a paragraph, I call this method in my subclass of
NSTextView:
-(void)setParagraphStyle:(NSString*)styleName
{
Document* doc = [[self.window windowController] document];
NamedStyle* sty = [doc.styleSet styleByName:styleName];
[self.textStorage addAttributes:sty.attributes
range:self.rangeForUserParagraphAttributeChange];
[self didChangeText];
}
Okay, I know that must be very wrong, because although doing it does alter the
text as I expect, it also blows up my text table and breaks or merges cells.
What should I be doing instead, rather than blithely calling
addAttributes:range:?
