Question

The program I am creating should work like Microsoft Excel, except in JAVA. It should also support cell formatting (Which is my problem). I have the code for detecting which cell is clicked, and what font to use working properly – I just can not figure out how to apply the Font to the cell! Google gave me CellRenderers, but it seems that cell renderers format the cell only when a condition is true. I want it to format with the specified Font it when it is called!

Can someone please help me, I am really confused!!!

I have already looked at the Java Tutorials.

My apologies if this question has been asked before!

Answer 1

this is what you are looking for,, this code snippet changes the font of all columns in a jTable..
I’m sure a slight modification should get your scenario covered.

for (int i = 0; i < jTable1.getColumnCount(); i ++) {
    TableColumn col = jTable1.getColumnModel().getColumn(i);
    col.setCellEditor(new MyTableCellEditor());
}


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 java.awt.Font("Arial Unicode MS", 0, 12));
        return component;
    }
}
