child tables go away when MultilineTableCellRenderer used

[ack1035]

Hello,
When I override getCellRenderer() on my hierarchical table class, and have it return a MultilineTableCellRenderer, the rows no longer expand to show the child tables. In fact the hasChild() method on my TableModel isn’t even called.

Is it possible to have rows that both expand into child tables and use a MultilineTableCellRenderer?

Thanks,
Alex

If possible, can you try to modify HierarchicalTableDemo to reproduce the issue and email or post here the changed code?

Thanks,

I emailed the modified code, which reproduced the following results:

-word wrap is now enabled, but
-items in the subtables that formerly had children no longer do ("ComboBox" and "CellEditors")

Here's an excerpt to show how I did this (around line 139):

TableModel model = ((TableModel) value);
if (model instanceof HierarchicalTableModel) {
HierarchicalTable childTable = new HierarchicalTable(model) {
@Override
public void scrollRectToVisible(Rectangle aRect) {
HierarchicalTableDemo.scrollRectToVisible(this, aRect);
}
TableCellRenderer cellRenderer =
new MultilineTableCellRenderer();

@Override
public TableCellRenderer getCellRenderer(int row, int column) {
return cellRenderer;
}
};
childTable.setRowAutoResizes(true);

...

The behavior I'd like is to have both the word wrap and not to lose subtables.

Thanks,
Alex

I see. Of course you won't see the +/- icon as you override our cell renderer that paints the +/- icon. The correct way is to use our CellRenderer/EditorManager way. Just get rid of your code of getCellRenderer and use the code below for the model.
