我有一串文字:“这是一个 |<good>| 到 |<ski>| 的山。”
我想要|<好>| 和|<滑雪>| 显示为红色、斜体、FontSize 9。
我已经设置了单独的 AttributeSets
StyleContext myProtected = StyleContext.getDefaultStyleContext();
AttributeSet attR = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Foreground, Color.RED);
AttributeSet attB = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Background, Color.BLUE);
AttributeSet attI = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Italic, Boolean.TRUE);
AttributeSet attS = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.FontSize, 9);
我有一个正确找到模式的正则表达式。但是,如果我尝试将多个 AttributeSets 设置为相同的匹配,则只有第一个尊重正则表达式。其他人只是将自己应用于整个字符串。这是整个班级:
class ElementHighlight2 extends DefaultStyledDocument {
//private final MutableAttributeSet XRED = new SimpleAttributeSet();
StyleContext myProtected = StyleContext.getDefaultStyleContext();
AttributeSet attR = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Foreground, Color.RED);
//AttributeSet attB = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Background, Color.BLUE);
AttributeSet attI = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.Italic, Boolean.TRUE);
AttributeSet attS = myProtected.addAttribute(myProtected.getEmptySet(), StyleConstants.FontSize, 9);
@Override
public void insertString (int offset, String Pstr, AttributeSet RedBlue) throws BadLocationException
{
super.insertString(offset, Pstr, RedBlue);
String text = getText(0, getLength());
int pre = pipeCharEnd(text, offset);
if (pre < 0) pre = 0;
int post = pipeCharStart(text, offset + Pstr.length());
int prewords = pre;
int postwords = pre;
while (postwords <= post) {
if (postwords == post || String.valueOf(text.charAt(postwords)).matches("\\|")) {
if (text.substring(prewords, postwords).matches("(\\|\\<[^\\>]*\\>)"))
setCharacterAttributes(prewords, postwords - prewords +1, attR, false);
setCharacterAttributes(prewords, postwords - prewords +1, attI, false);
setCharacterAttributes(prewords, postwords - prewords +1, attS, false);
prewords = postwords;
}
postwords++;
}
}
如果有人可以帮助我学习我尚未发现的最佳实践来实现这一目标,我将不胜感激。
