Question

I have a JTable such that:

ID #:          Name:
 0             Entry 0
 1             Entry 1
 2             Entry 2

When a variable:

private int HighlightEntryID = 2;

is set to an ID #, the JTable should then be able to highlight the corresponding entry.

I have created a Custom Cell Renderer and with the following code:

TableColumn column = CISTable.getColumnModel().getColumn(0);
column.setCellRenderer(new CustomCellRenderer());

I render cells based on the ID # column. My questions are:

• It only highlights a specific (row, column) entry. I want to highlight the whole row. How do I highlight other columns in the same row?
• When the variable: HighlightEntryID is changed, the JTable doesn’t automatically reflect the change. I must refresh the table manually. How do I refresh it automatically?

It only highlights a specific (row, column) entry. I want to highlight the whole row. How do I highlight other columns in the same row?

I like to use Table Row Rendering for this.

When the variable: HighlightEntryID is changed, the JTable doesn’t automatically reflect the change. I must refresh the table manually. How do I refresh it automatically?

Invoke the following to force repainting of the entire table:

table.repaint();
