本文实例为大家分享了Java swing 仿QQ账号密码输入框，供大家参考，具体内容如下 主要思路是自己定义 AccountPanel 和 PasswordPanel 类，继承JPanel，通过 paintComponent...this.borderc=borderc; } public void setBorder(boolean flag){ this.flag=flag; } @Override public void paintComponent...(Graphics g){ super.paintComponent(g); Graphics2D g2=(Graphics2D) g; //设置绘图质量 g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING...this.borderc=borderc; } public void setBorder(boolean flag){ this.flag=flag; } @Override public void paintComponent...(Graphics g){ super.paintComponent(g); Graphics2D g2=(Graphics2D) g; //设置绘图质量 g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING
绘制 在Jpanel类里面有一个paintComponent方法，这个方法是自带的一个方法，需要绘制的操作都要在这里面画。paintComponent带了一个画笔参数。...private class AlgoCanvas extends JPanel { @Override public void paintComponent(Graphics...g) { super.paintComponent(g); g.drawOval(50, 50, 300, 300); } }...但其实如果是仅仅在2D图像上画其实可以使用Graphic2D来画，把Graphic转换成Graphic2D就好了，而paintComponent是没有2D的这个参数的。...private class AlgoCanvas extends JPanel { @Override public void paintComponent(Graphics
splashWindow.setSize(500, 400); JPanel jPanel = new javax.swing.JPanel(){ protected void paintComponent...(java.awt.Graphics g){ super.paintComponent(g); g.drawImage(new ImageIcon("splash_background.jpg
游戏的面板 若是没有super.paintComponent(g);，则会出现闪屏， 在主启动类StartGame中添加frame.add(new GamePanel());， package Snake...public class GamePanel extends JPanel { //绘制面板，游戏中所有东西都用这个画笔来画 @Override protected void paintComponent...(Graphics g){ super.paintComponent(g); //清屏 this.setBackground(Color.BLACK); }...游戏失败判定 先设置一个失败标志， //游戏失败判定 boolean isFail = false; //游戏失败状态 然后在绘制画板paintComponent(Graphics g)中设置一个失败回显...积分获取系统 先定义一个用于存储积分的对象score，然后在绘制面板paintComponent(Graphics g)中显示出积分来， /** * 显示积分 */ g.setColor(Color.white
0.0, cv.width, cv.height) cv.graphicsContext2D.strokeRect(0.0,0.0,cv.width,cv.height) paintComponent...(cv.graphicsContext2D) } private fun paintComponent(g: GraphicsContext) { g.fill = Color.RED...it.centerY, it.radius, it.radius) } } init { circles = genCircles() paintComponent
(Graphics g) { super.paintComponent(g); //清屏 this.setBackground(Color.white); //...(Graphics g) { super.paintComponent(g); //清屏 this.setBackground(Color.white); //...(Graphics g) { super.paintComponent(g); //清屏 this.setBackground(Color.white); //...(Graphics g) { super.paintComponent(g); //清屏 this.setBackground(Color.white); //...(Graphics g) { super.paintComponent(g); //清屏 this.setBackground(Color.white); //
val jPanel = object : JPanel() { override fun paintComponent(g: Graphics) { super.paintComponent(g
此时阴影的位置就显得格外重要了，需要自定义左右阴影的偏移量 总所周知，对于位置的表示是坐标即横纵坐标，这时就需要设置4个偏移量——左阴影x、左阴影y、右阴影x、右阴影y 然后覆盖JLabel类中的paintComponent...覆写paintComponent,以达到画3次就能画出阴影效果 public void paintComponent(Graphics g){ //这句感觉是可有可无的，目的是让字体圆润柔和些
2.利用paintComponent（）函数，进行在正方格交叉处点击出现黑棋与白棋落子，否则的话将不会出现下棋子的标志 限制棋子的落子，如果下到棋盘外，不会落子 4.侦查区域是落子标志，点击落子区域...6.与画布棋盘时相似，使用paintComponent（）函数进行棋子落子的判定，鼠标点在格子十字交叉点的周围进行分析 在MouseEvent（鼠标监听事件类）里面包含鼠标被点击等事件的处理方法。...; return true; } } return false; } protected void paintComponent(Graphics...g){ super.paintComponent(g); Graphics2D g2 = (Graphics2D)g; for(int i=1;i<=16;i++){...g.fillOval(0, 0, getSize().width-1, getSize().height-1); // 在焦点上画出一个标签 super.paintComponent
(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g;...(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g;...(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g;...(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g;...(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g;
imgPath; setSize(width,height); setVisible(true); } @Override public void paintComponent...(Graphics gs) { Graphics2D g = (Graphics2D) gs; super.paintComponent(g); //画背景图片
this.image = image; 22 } 23 24 // 固定背景图片，允许这个JPanel可以在图片上添加其他组件 25 protected void paintComponent
val jPanel = object : JPanel() { override fun paintComponent(g: Graphics) { super.paintComponent
img = new imagelcon(url).getimage(); } // 图片展示的位置 protected void paintComponent(Graphics...g){ super.paintComponent(g); g.drawimage(img,0,0,this); // 以左上角为起点 } } 2 登录窗体 创建
.*; public class MyDrawPanel extends JPanel { public void paintComponent(Graphics g){ g.fillRect(0, 0
private static final int LINE_LENGTH = 90; // 线段的长度 @Override protected void paintComponent...(Graphics g) { super.paintComponent(g); for (int i = 0; i < balloons.size();...100; private static final int BALLOON_HEIGHT = 150; @Override protected void paintComponent...(Graphics g) { super.paintComponent(g); for (int i = 0; i < balloons.size();
list.getSelectionForeground() : list.getForeground(); return this; } public void paintComponent...接下来我们有实现了2个方法，其中PaintComponent负责Cell的绘制，GetPreferedSize负责设置Cell的尺寸。对于尺寸有一点需要注意，上述代码给的是一个固定尺寸。...如果你想在绘制Cell的时候加入什么花样，那么尽管在PaintComponent中施展你的才华吧，上述代码只提供了在指定位置绘制文本，算是抛砖引玉了。
startX += dx; startY += dy; } }); } public void paintComponent...(Graphics g) { super.paintComponent(g); // 画布进行整体偏移 Graphics2D g2 = (Graphics2D
