我正在编写一个应用程序,我必须在画布上绘制JTable组件。但经过我的几次尝试仍然无法绘制完整的JTable画面。我试图使用getCellRect api使用JTable的特定单元格的大小绘制,但是当数据很大时无法在画布上绘制特定单元格。以下是示例代码: -

请建议重新绘制相应的JTable字体和边框。
答案 0 :(得分:4)
有几个问题显而易见:
您似乎正在使用现有JTable
的几何图形创建自己的表格视图;这些尺寸可能在pack()
之后才有效。
您遍历adjustColumns
中的列,但只有最后一列宽度在panel
中设置,然后变为表格中的常量宽度。
与JTable
本身相比,您的实施效果会很差,使用flyweight rendering,图示为here。
调整帧大小时,panel
消失;您应该明确致电repaint
,聆听TableModel
,或使用JTable
本身。
从Java 5开始,autoboxing允许以下内容;比较:
{"John", "Doe", "Rowing", new Integer(3), new Boolean(true)}
{"John", "Doe", "Rowing", 3, true}
不要替换内容窗格; add()
你的小组对此;比较:
frame.setContentPane(newContentPane);
frame.add(newContentPane);
您对GridLayout(3,0)
的使用表明存在误解;要在一列中获取任意数量的行,请使用GridLayout(0, 1)
。
在您展开JPanel
时,请注意“Swing程序应覆盖paintComponent()
而不是覆盖paint()
;”另见Painting in AWT and Swing: The Paint Methods。

另一种方法是将表格呈现为JLabel
中的HTML。
import java.awt.*;
import javax.swing.*;
public class HTMLTableDemo {
HTMLTableDemo() {
StringBuilder sb = new StringBuilder();
sb.append("<html><body><table border=1>");
sb.append("<tr>");
for ( String columnName : columnNames ) {
sb.append("<th>");
sb.append(columnName);
sb.append("</th>");
}
sb.append("</tr>");
for (Object[] row : data) {
sb.append("<tr>");
for (Object value : row) {
sb.append("<td>");
sb.append(value);
sb.append("</td>");
}
sb.append("</tr>");
}
sb.append("</table>");
JLabel html = new JLabel(sb.toString());
JOptionPane.showMessageDialog(null, html);
}
public static void main(String[] args) {
Runnable r = new Runnable() {
@Override
public void run() {
new HTMLTableDemo();
}
};
SwingUtilities.invokeLater(r);
}
String[] columnNames = {
"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian"
};
Object[][] data = {
{"Kathy", "Smith", "Snowboarding", new Integer(5), new Boolean(false)},
{"John", "Doe", "Rowing", new Integer(3), new Boolean(true)},
{"Sue", "Black", "Knitting", new Integer(2), new Boolean(false)},
{"Jane", "White", "Speed reading", new Integer(20), new Boolean(true)},
{"Joe", "Brown", "Pool", new Integer(10), new Boolean(false)}
};
}
要将其呈现给Graphics
个实例,请参阅this answer上的LabelRenderTest.java
