}

plus i found this code on the Internet and its works fine when i use it with JcheckBox but not with
the combo
its driving me crazy because its so short and work perfectly , i don't get ! usually i go like (if ( bold.isSlected set the j textArea to bold then another if else for italic condition and third one for them both , but it never work when ever i start to selcted them both then deselecte etc
i tryied to check the selection for all the checkboxes like this (if bold.is selected go and check the italic but it works for the first selection, + plus it's really long i wanna do it like this code )

	public void itemStateChanged(ItemEvent ie) {
 
		setState();
 
	}
 
 
 
private void setState() {
		String Text;
		int Style;
		Font font;
 
		Text = jta.getText();
		Style = 0;
		if (Bold.isSelected()) {
			Style = Style | Font.BOLD;
		} else {
		}
		if (Italic.isSelected()) {
			Style = Style | Font.ITALIC;
		} else {
		}
 
		font = new Font("SansSerif", Style, 12);
		jta.setFont(font);
		jta.setText(Text);
