当我这样做:的Java Swing圆角边框的JTextField
LineBorder lineBorder =new LineBorder(Color.white, 8, true);
jTextField2.setBorder(lineBorder);
我得到这样的结果,如:
我怎样才能具有圆形边框无方角可见,文本半切?
非常感谢。

您可以覆盖JTextFiled
建立自己的圆角JTextField
。您必须覆盖它的方法paintComponent()
,paintBorder()
和方法。您需要将roundRect绘制为文本字段的形状。
例子:
public class RoundJTextField extends JTextField {
private Shape shape;
public RoundJTextField(int size) {
super(size);
setOpaque(false); // As suggested by @AVD in comment.
}
protected void paintComponent(Graphics g) {
g.setColor(getBackground());
g.fillRoundRect(0, 0, getWidth()-1, getHeight()-1, 15, 15);
super.paintComponent(g);
}
protected void paintBorder(Graphics g) {
g.setColor(getForeground());
g.drawRoundRect(0, 0, getWidth()-1, getHeight()-1, 15, 15);
}
public boolean contains(int x, int y) {
if (shape == null || !shape.getBounds().equals(getBounds())) {
shape = new RoundRectangle2D.Float(0, 0, getWidth()-1, getHeight()-1, 15, 15);
}
return shape.contains(x, y);
}
}
要看到这个效果:
JFrame frame = new JFrame("Rounded corner text filed demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 400);
frame.setLayout(new FlowLayout());
JTextField field = new RoundJTextField(15);
frame.add(field);
frame.setVisible(true);
非常相似,@Harry Joy的答案 - 只是去充分的距离,为outlined in a recent answer
这将修改您在整个应用程序
创建任何JTextField中删除它只是在你的第一个窗口的开始,这将影响到每个JTextField的。
UIManager.put("TextField.background", Color.WHITE);
UIManager.put("TextField.border", BorderFactory.createCompoundBorder(
new CustomeBorder(),
new EmptyBorder(new Insets(4,4,4,4))));
自定义边框
@SuppressWarnings("serial")
public static class CustomeBorder extends AbstractBorder{
@Override
public void paintBorder(Component c, Graphics g, int x, int y,
int width, int height) {
super.paintBorder(c, g, x, y, width, height);
Graphics2D g2d = (Graphics2D)g;
g2d.setPaint(COLOR_BORDE_SIMPLE);
Shape shape = new RoundRectangle2D.Float(0, 0, c.getWidth()-1, c.getHeight()-1,9, 9);
g2d.draw(shape);
}
}
