如何从鼠标位置转换为字符位置中的Java Swing一个JEditorPane

Question

目前，我正在试图解决一个问题，我需要找到基于鼠标点击的地方在一个JEditorPane一段文本的位置。

基本上，当用户右击了一个字，我需要找出这个词是什么。要做到这一点，我需要找出在用户点击文本哪个位置。我知道我可以很容易地从被传递到方法的mousePressed中的MouseEvent鼠标的位置，并且有人告诉我，你可以将它转换为获得在一段文本字符索引 - 但是我想不出怎么办此

我曾尝试viewToModel（）方法JEditorPane中但是这所以无论是我用错了，或不以这种方式工作是给我回的文本错误的位置。

任何想法？

Answer 1

Invoking viewToModel() is the correct way to do this:

public void mouseClicked(MouseEvent e) {
    JEditorPane editor = (JEditorPane) e.getSource();
    Point pt = new Point(e.getX(), e.getY());
    int pos = editor.viewToModel(pt);
    // whatever you need to do here
}

Answer 2

I've solved this problem on my own. It turns out viewToModel() is exactly what I should be using here, the problem was that I was passing in the wrong Point to it.

From the MouseEvent, I was using the getLocationOnScreen() method to work out the point when in fact I should have been using the getPoint() method.
