在Swing中重新定位GridLayout

标签: java swing

我创建了一个8x8 GridLayout的棋盘游戏,每个网格中都有一个不透明的按钮。我创建了以8x8表格的形式显示,当用户点击任何单元格时,它应该执行一些操作。现在,网格看起来像:

我希望它通过动画以一定的角度重新定位它,如下所示:

是否可以使用Swingrepaint中执行此操作?如果没有,是否有更好的工具包可以使用Swing以外的其他工具包,以便我可以为此设置动画?

更改实时组件的状态需要更多,然后只需绘画......

例如,基于Boann的例子......

Swing中的绘画是一个复杂且优化的过程,并不总是以线性方式完成。

话虽如此,有一种方法,但你需要为它工作。

这是基于JXLayer API和pbjar示例

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import org.jdesktop.jxlayer.JXLayer;
import org.pbjar.jxlayer.demo.TransformUtils;
import org.pbjar.jxlayer.plaf.ext.transform.DefaultTransformModel;

public class Twister02 {

    public static void main(String[] args) {
        new Twister02();
    }

    public Twister02() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new ExamplePane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }
        });
    }

    public class ExamplePane extends JPanel {

        private JSlider slider;
        private FieldPane fieldPane;
        private DefaultTransformModel transformModel;

        public ExamplePane() {

            setLayout(new BorderLayout());

            slider = new JSlider(0, 360);
            slider.setValue(0);
            slider.addChangeListener(new ChangeListener() {
                @Override
                public void stateChanged(ChangeEvent e) {

                    transformModel.setRotation(Math.toRadians(slider.getValue()));

                }
            });

            fieldPane = new FieldPane();

            transformModel = new DefaultTransformModel();
            transformModel.setRotation(Math.toRadians(0));
            transformModel.setScaleToPreferredSize(true);
            JXLayer<JComponent> rotatePane = TransformUtils.createTransformJXLayer(fieldPane, transformModel);

            add(slider, BorderLayout.NORTH);
            add(rotatePane);

        }
    }

    public class FieldPane extends JPanel {

        public FieldPane() {
            setLayout(new GridLayout(8, 8));
            for (int i = 0; i < 64; i++) {
                add(new JButton("" + i));
            }
        }

    }
}

现在问题是,pbjar的例子似乎已经从互联网的面孔消失了,令我们非常失望。

重写容器的paintChildren方法以将变换应用于Graphics对象,然后使用它调用super.paintChildren。将按钮网格绕其中心稍微旋转的简单示例:

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new GridLayout(8, 8)) {
    @Override
    public void paintChildren(Graphics g1) {
        Graphics2D g = (Graphics2D)g1;
        g.rotate(0.3, getWidth() / 2, getHeight() / 2);
        super.paintChildren(g);
    }
};
frame.add(panel);
for (int i = 0; i < 64; i++) panel.add(new JButton("" + i));

frame.pack();
frame.setVisible(true);

它的样子(之前/之后):

编辑:虽然它看起来很聪明,但实际上你无法在旋转位置点击这些按钮;可能使用AffineTransform对象来转换鼠标事件并将它们重定向到正确的子正确组件,但我还没有尝试过。重绘区域也可能存在问题。 ...也许绘制自己的网格(@ Masud的答案)会避免试图在Swing之上破解这个功能。

是否可以使用重绘在Swing中执行此操作?如果没有,是否有   更好的工具包可以使用除Swing之外的其他工具包以便我可以动画这个吗?

不,GridLayout无法实现。将JPanel上的图片与drawLine一起使用,并使用Timer设置动画。
