问题描述
我有一个带有自定义表模型的表,该表模型有两列.列0是ImageIcon类,列1是String类.
I have a table with a custom table model which has two columns. Column 0 is an ImageIcon class, and Column 1 is a String class.
public Class<?> getColumnClass(int col) {
if (col == 0) {
return ImageIcon.class;
} else {
return String.class;
}
}
当我定义要添加到列中的新TableCellRenderer类以便对单元格进行样式设置时,它将覆盖ImageIcon类并将其设置为String.
When I define a new TableCellRenderer class to be added to the columns so I can style the cells, it overwrites the ImageIcon class and sets it to a String.
public class CustomTableCellRenderer extends DefaultTableCellRenderer
{
public Component getTableCellRendererComponent (JTable table, Object obj, boolean isSelected, boolean hasFocus, int row, int
column)
{
Component cell = super.getTableCellRendererComponent(table,
obj, isSelected, hasFocus, row, column);
if(isSelected)
cell.setBackground(Color.BLUE);
return cell;
}
}
关于如何解决此问题的任何想法?
Any ideas on how to fix this?
我的错误,某种程度上是隐藏的:
My mistake, it is sort of hidden:
所以问题在于,当我定义此TableCellRenderer类以对表进行样式设置时,表中的ImageIcon列将变为"File:..."之类的字符串,而不是实际的图标.
So the problem is that, when I define this TableCellRenderer class to style my table, the ImageIcon columns in my table turn to Strings like "File:..." instead of the actual icon.
推荐答案
无需创建自定义渲染器. JTable allready支持包含Icon的列的默认渲染器.您需要做的就是重写您似乎正在执行的getColumnClass()方法.
There is no need to create a custom renderer. JTable allready supports a default renderer for columns containing an Icon. All you need to do is override the getColumnClass() method, which you appear to be doing.
