Java:某些表单元素被其他元素部分覆盖

标签 java swing jframe layout-manager

我设计了一个表单，用于在框架内显示图表和表格。这是代码:

package ExaData;


import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.EventQueue;
import java.awt.FlowLayout;

           this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); 


            PGA_CHECK.addItemListener(new ItemListener() {

        );
        CategoryPlot plot = (CategoryPlot) chart.getPlot();


        NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
        rangeAxis.setNumberFormatOverride(NumberFormat.getPercentInstance());

    RefineryUtilities.centerFrameOnScreen(this);     
    this.setVisible(true);

}
 public void update()

       chart = createChart(createDataset());
   CP=new ChartPanel(chart);  
           this.add(CP, BorderLayout.CENTER);
    this.setVisible(true);
 }


  public static void main(final String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {

            }
        });
    }
}

问题是，当我运行这个时，我的表格与图表重叠。我该如何解决这个问题？

这是屏幕截图: enter image description here

编辑:我用简单的图像替换了图表。它覆盖了复选框面板，当我尝试调整窗口大小时，它也会导致一些故障。这是我编辑的代码:

最佳答案

这不是答案。只是一个建议，对于评论来说太长了

另一个建议，因为我认为这个问题可能与我们昨天的讨论有关，您正在尝试将动态组件添加到框架中 - 相反，不要这样做。 GUI Builder 默认提供的GroupLayout 使得动态添加组件变得困难。只需创建一个已具备所有组件的 JDialog 表单，然后通过其构造函数将数据传递给它即可。该数据应该是制定表格和图表所需的数据。像这样的事情

public class ChartTableDialog extends JDialog {
    private int[][] data;

    public ChartTableDialog(final JFrame frame, boolean modal, int[][] data) {
        super(frame, model);
        this.data = data;
    }

    // somewhere else in the code you will use data[][] for formulate
    // your chart and your table
}

然后在您的主 JFrame 表单中，假设有一个按钮触发 JDialog 弹出，收集数据，然后将其传递给 JDilaog >。像这样的事情

private void jButton1ActionPerformed(ActionEvent e) {
    int[][] data = getSomeData();

    new ChartTableDialog(this, true, data);
}

这将是最简单的方法。

另一种方法是使用CardLayout，但我必须与您一起完成整个教程，了解如何使用 GUI Builder 执行此操作，因为它有点复杂。所以我现在建议第一个选择。
