How to clear all styling from StyledDocument?

Question

StyledDocument contains various methods to set styles. Like setCharacterAttributes.

But I can't see any methods to remove styles.

Is there any?

Answer 1

It is impossible to "clear" styles. One should obtain a "default" style with the following technique:

Style defaultStyle = StyleContext.
   getDefaultStyleContext().
   getStyle(StyleContext.DEFAULT_STYLE);

Then apply it with:

sampleDocument.setCharacterAttributes(0, sampleDocument.getLength(), defaultStyle, true);

Answer 2

StyledDocument has a removeStyle method that removes the named style.

Your document has to have character attributes. You can set the character attributes, and later set the character attributes to default values.
