Custom Attributes

Hi,

I am trying to figure out how to implement my own custom attributes. I want some of these attributes to change the way that text is rendered. For instance I need an "all caps" attribute.

I discovered that I can easily create whatever attributes I want - but the more challenging part is implementing the rendering of the new attribute.

I gather I have to subclass NSTextManager and specifically override - drawGlyphsForGlyphRange. This will need to search the text to be rendered for my new attribute and render the attributed text in the manner I want. But I am not clear what the over-ridden method will look like and how to go about rendering the new glyphs.

Is there any place I should be looking for help?

Glyn
