在编辑时更改JTable单元格的字体

问题描述

我已经在JTable中设置了默认字体，如下所示

I have set the default font in my JTable as show below

myTable.setFont(new java.awt.Font("Verdana", 1, 10));

我想在JTable中显示更大的字体，同时在单元格中键入一些数据.因此，我使用了 MyTableCellEditor 自定义类.

I wanted to show a bigger font in my JTable,while some data is being typed into the cells.So I used MyTableCellEditor custom class.

public class MyTableCellEditor extends AbstractCellEditor implements TableCellEditor {

    JComponent component = new JTextField();

    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected,
      int rowIndex, int vColIndex) {

        ((JTextField) component).setText((String) value);
        ((JTextField) component).setFont(new Font("Verdana", 1, 12));

        return component;
    }

    public Object getCellEditorValue() {
        return ((JTextField) component).getText();
    }
}

下面是我将CustomCellEditor附加到表中的代码.

Below is the code where I attached the CustomCellEditor to my table.

myTable.getColumnModel().getColumn(1).setCellEditor(new MyTableCellEditor());

但是此代码似乎不起作用.在编辑时，单元字体变小了，一旦我完成编辑并按Enter，我设置的默认JTable字体(Verdana 10)就生效了.为什么会这样?我已经将CustomCellEditor字体设置为(Verdana 12).

But this code do not seem to work.The cells font becomes small while editing and once I finish editing and hit enter,the default JTable font which I set ( Verdana 10 ) takes effect.Why is this happening ? I have already set CustomCellEditor font as ( Verdana 12 ) to my cells.

推荐答案

请勿为此创建新类.只需更改DefaultCellEditor的属性即可:

Don't create a new class for this. Just change the property of the DefaultCellEditor:

JTextField textField = new JTextField();
textField.setFont(new Font("Verdana", 1, 12));
textField.setBorder(new LineBorder(Color.BLACK));
DefaultCellEditor dce = new DefaultCellEditor( textField );
myTable.getColumnModel().getColumn(1).setCellEditor(dce);
