Question

I just faced an interesting thing.

I was changing selected text style. The thing is when I change style for ONE WORD one by one it\'s fine but next if I select a wh

Answer 1

TextComponentDemo, discussed in How to Use Editor Panes and Text Panes, is a good example of how to manage this as well as other text component features.

Addendum: TextComponentDemo relies on pre-defined Action objects to handle editing tasks. Conveniently, StyledEditorKit contains a series of nested classes that derive from StyledTextAction. As a concrete example, here's how one might add an AlignmentAction to the Style menu of TextComponentDemo in the method createStyleMenu():

protected JMenu createStyleMenu() {
    JMenu menu = new JMenu("Style");

    Action action = new StyledEditorKit.AlignmentAction(
        "left-justify", StyleConstants.ALIGN_LEFT);
    action.putValue(Action.NAME, "Left");
    menu.add(action);
    menu.addSeparator();
    ...
}

The remaining (arbitrary) alignment action names are defined privately in StyledEditorKit.

Addendum: setCharacterAttributes() is the common routine used by the nested editing actions. It invokes a method of the same name in StyledDocument, as proposed by @StanislavL.

Addendum: I am unable to reproduce the effect you describe. When I set the color of the selection, the style attributes remain unchanged.

Addendum: The StyledEditorKit actions work just as well with a JButton or JToolBar.

new JButton(new StyledEditorKit.ForegroundAction("Red", Color.red))

Answer 2

Use this.getTextPane().getStyledDocument().setCharacterAttributes()
