Question

我为我的JTabbedPane创建了一个自定义LaF，唯一的问题是它只呈现标签，而不是文本，请帮忙，我已经尝试了一切！

package com.jama.lyricist.ui;

import java.awt.Color;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics;
import java.awt.Insets;
import java.awt.Rectangle;

import javax.swing.plaf.basic.BasicTabbedPaneUI;

public class AdvancedTabbedPaneUI extends BasicTabbedPaneUI{

    @Override
    protected void paintTab(Graphics g, int tabPlacement, Rectangle[] rects, int        tabIndex, Rectangle iconRect, Rectangle textRect) {
        Color savedColor = g.getColor();
        g.setColor(new Color(238,238,238));
        g.fillRect(rects[tabIndex].x, rects[tabIndex].y, 
               rects[tabIndex].width, rects[tabIndex].height);
        g.setColor(new Color(153, 153, 153));
        g.drawRect(rects[tabIndex].x, rects[tabIndex].y, 
               rects[tabIndex].width, rects[tabIndex].height);
        g.setColor(new Color(102,102,102));
        g.setColor(savedColor);
    }


    private final Insets borderInsets = new Insets(0, 0, 0, 0);
    @Override
    protected void paintContentBorder(Graphics g, int tabPlacement, int selectedIndex) {
    }
    @Override
    protected Insets getContentBorderInsets(int tabPlacement) {
        return borderInsets;
    }

    @Override
    protected void paintContentBorderTopEdge(Graphics g, int tabPlacement,
                           int selectedIndex, int x, int y, int w, int h) {
        super.paintContentBorderTopEdge(g, tabPlacement, -1, x, y, w, h);
    }

}

输出：Output

Answer 1

通过覆盖paintTab（）方法，您将阻止标题被基类绘制。

您有两种选择之一：

覆盖paintTabBackground（）和paintTabBorder（）而不是覆盖paintTab（）方法，让基类绘制标题
在paintTab（）方法中自己绘制标题

自定义JTabbedPane LaF不显示文本
