如何获得插入字符在JTextField中的像素位置？

Question

How to get Caret position in pixels in JTextField ? There is a method getCaret().getDot() , but it returns symbol count, not pixels. Is there some method besides FontMetrics ?

Answer 1

在API中，您可以使用：

int pixelPosition = textField.modelToView( textField.getCaretPosition() ).x;

Answer 2

Given JTextField someJTextField the following code should give you the pixel position of the care:

FontMetrics fm = myJTextField.getFontMetrics();
int caret = someJTextField.getCaret().getDot();


int pixelPosition = fm.stringWidth(myJTextField.getText(0, caret)) -
                                   myJTextField.getScrollOffset();
