I'm trying to create a custom “Change font” NSPopupButton for a Mac App (not an iOS App). I can detect a change in font selection:
long fontItemIndex = [fontPopup indexOfSelectedItem];
NSMenuItem *fontItem = [fontPopup itemAtIndex:(int)selectedFontItemIndex];
NSString *fontName = [selectedFontItem title];
Given this NSString of a font name, I cannot seem to find out how to actually change the selected text in my NSTextView textView
to this new font.
I'm simply dazzled by the official documentation: it seems convertFont:toFamily:
is what I need. When I do this:
NSFont *font = [NSFont fontWithName:fontName size:12.0];
[textView setFont:font];
It sets all text in the text view, not just the selected text. But when I do this:
NSFontManager *fontManager = [NSFontManager sharedFontManager];
[fontManager convertFont:[fontManager selectedFont] toFamily:fontName];
it doesn't do a thing. What am I missing?
