如何操纵颜色值？

Question

我创建了一个表,其中一个参数是一个颜色,就像这样

表http://www.freeimagehosting.net/newuploads/fjuzi.png

我没有从我创建的表模型中覆盖getValue方法,这意味着当我得到它们作为对象的颜色值时.如果我将它们存储为对象或字符串,我将获得以下值:

java.awt.Color[r=255,g=0,b=0]

这是我的桌子模型,以防万一:

private static final Object[][] DATA = {
     { "1", "Task 1", new Integer(10), false, new Integer(0), Color.red },
     { "2", "Task 2", new Integer(10), false, new Integer(0), Color.blue },
     { "3", "Task 3", new Integer(10), false, new Integer(0),
           Color.green },
     { "4", "Task 4", new Integer(10), false, new Integer(0),
           Color.orange },
     { "5", "Task 5", new Integer(10), false, new Integer(0),
           Color.black } };

 private MyTableModel myTableModel = new MyTableModel(DATA);





class MyTableModel extends DefaultTableModel {
private static final String[] COLUMN_NAMES = { "Station #", "Name",
     "avg Time", "Buffer", "Buffer Parts", "Color" };

public MyTableModel(Object[][] data) {
  super(data, COLUMN_NAMES);
}

@Override
public Class getColumnClass(int c) {
    //System.out.println("Class for " + c + ": " + getValueAt(0, c).getClass().toString());
    return getValueAt(0, c).getClass();        
}


@Override
public boolean isCellEditable(int row, int col) {

  if (col == 0) {
     return false;
  } else if (col == 4) {
     boolean di = (Boolean) getValueAt(row, (col - 1));
     if (!di) {
        return false;
     } else {
        return true;
     }
  } else {
     return true;
  }
}

public void printDebugData() {
  int numRows = getRowCount();
  int numCols = getColumnCount();

  for (int i = 0; i < numRows; i++) {
     System.out.print("    row " + i + ":");
     for (int j = 0; j < numCols; j++) {
        Object datum = getValueAt(i, j);
        // System.out.print("  " + data[i][j]);
        System.out.print("  " + datum);
     }
     System.out.println();
  }
  System.out.println("--------------------------");
 }
}

表中的所有值都存储在哈希映射中,这些哈希映射会传递到另一个类,我需要创建一个颜色向量,以便存储已在表上设置的颜色.

Station 1=[1, Task 1, 10, false, 0, java.awt.Color[r=255,g=0,b=0]]
Station 2=[2, Task 2, 10, false, 0, java.awt.Color[r=0,g=0,b=255]]
Station 3=[3, Task 3, 10, false, 0, java.awt.Color[r=0,g=255,b=0]]
Station 4=[4, Task 4, 10, false, 0, java.awt.Color[r=255,g=200,b=0]]
Station 5=[5, Task 5, 10, false, 0, java.awt.Color[r=0,g=0,b=0]]

我环顾四周但找不到任何信息,那么处理它的最佳方法是什么,以便我可以存储要传递的值使用的颜色？

我希望我明确表示,如果需要任何其他信息,请告诉我.

你得到的价值getValueAt()是实际的java.awt.Color对象; 只是方法的返回类型是Object.你需要施放价值:

Color color = (Color) tableModel.getValueAt(0, 5);

现在你有一个Color指向对象的变量,你可以随心所欲地做任何事情.
