完全痴線 - JTextComponent個setCaretPosition完來係錯
2019-07-13
如果你放”abc\ndef”落JTextComponent, 佢會變Q左”abc\r\ndef”, 連帶影響埋setCaretPosition()會錯位，補救方法如下:
int count = StringUtils.countMatches(jTextComponent.getText().substring(0, data.caretPosition), "\r\n");
jTextComponent.setCaretPosition(data.caretPosition - count);
經過修正之後, 我個netbeans outline plugin回復正常了
