Hi,
I'm having an issue with my JTable that can hopefully be resolved without having to change my JTable custom cell renderer. I have a JTable where each column is sortable. There was a sortable table class made available before java6, and thats what I'm using. I believe this sortable table requires a custom cell renderer that extends JLabel for the sort to work right. What I would like to be able to handle is the following:
The third column in my table may have multiple lines in it. I would like for the ROW containing that cell with the multiple lines in it to resize, so that the row is clearly delineated, and that the multiple lines in the column show up properly. I've seen multiple posting on some variation of this problem, but
none of those solutions have worked for me.
Here is my cell renderer so far:
private final class MyTableCellRenderer extends DefaultTableCellRenderer {
public MyTableCellRenderer () {
super();
}
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
Component cell = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
if(value instanceof Long) {
Number n = (Number) value;
NumberFormat formatter = NumberFormat.getIntegerInstance(Environment.getLocale());
value = formatter.format(n.longValue());
super.setValue(value);
((JLabel)cell).setHorizontalAlignment(JLabel.RIGHT);
//((JLabel)cell).setFont( monoFont );
} else if (value instanceof Double) {
Number n = (Number) value;
NumberFormat formatter = NumberFormat.getPercentInstance(Environment.getLocale());
formatter.setMinimumFractionDigits (3);
formatter.setMaximumFractionDigits (3);
value = formatter.format(n.doubleValue());
super.setValue(value);
((JLabel)cell).setHorizontalAlignment(JLabel.RIGHT);
//((JLabel)cell).setFont( monoFont );
} else if (value instanceof String) {
if (column == 2) {
String s = "<html><body>";
//System.out.println("value = " +value);
String[] pieces = ((String)value).split("\\n");
for(int i = 0; i < pieces.length; i++) {
//System.out.println("\tpieces["+i+"] = " +pieces);
s += pieces[i];
s += "<br>";
}
s += "</body></html>";
((JLabel)cell).setText(s);
}
if (column == 3) {
String s = "<html> ";
String[] pieces = ((String)value).split("/");
for(int i = 0; i < pieces.length - 1; i++ )
s += pieces[i] + ".";
s = s + "<B>" + pieces[pieces.length -1] + "</B>" + "</html>";
((JLabel)cell).setText(s);
}
((JLabel)cell).setHorizontalAlignment(JLabel.LEFT);
//((JLabel)cell).setText(s);
((JLabel)cell).setBorder(new EmptyBorder(0,10,0,0));
}
return cell;
}
}
