我正在使用扩展 AbstractTableModel 的 CustomTableModel 创建一个表。我无法使用我的自定义模型将 JButton 添加到列中。如果我对模型执行 new JButton("One") .. 我看到的是文本“javax.swing.JButton[,0 ....,defaultCapable=true]”而不是按钮。任何帮助表示赞赏。
public class CustomModelForTable extends AbstractTableModel {
/**
*
*/
private static final long serialVersionUID = 1L;
private String[] columnNames = {"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian",
"Button"};
private Object[][] data = {
{"Kathy", "Smith", "Snowboarding", new Integer(5), new Boolean(false), new JButton("One")},
{"John", "Doe", "Rowing", new Integer(3), new Boolean(true), new JButton("Two")},
{"Sue", "Black", "Knitting", new Integer(2), new Boolean(false), new JButton("three")},
{"Jane", "White", "Speed reading", new Integer(20), new Boolean(true), new JButton("Four")},
{"Joe", "Brown", "Pool", new Integer(10), new Boolean(false), new JButton("Five")}
};
// # of Rows;
public int getRowCount() {
return data.length;
}
// # of Columns;
public int getColumnCount() {
return columnNames.length;
}
public Object getValueAt(int rowIndex, int columnIndex) {
return data[rowIndex][columnIndex];
}
public Class getColumnClass(int column) {
return getValueAt(0, column).getClass();
}
public boolean isCellEditable(int rowIndex, int columnIndex) {
return true;
}
public void setValueAt(Object value, int rowIndex, int columnIndex) {
if(isCellEditable(rowIndex, columnIndex)) {
data[rowIndex][columnIndex] = value;
}
}
}
编辑: 我能够通过实现 TableCellRenderer 添加 JButton。谢谢大家。
