Hi,

Anyone knows why TableTree widget is deprecated in Eclipse 3.1?
Tree is suggested to replace TableTree. But Tree does not cover all the
features of the TableTree widget.

Thanks.

The functionality was somewhat limited. For example, the tree stuff couldn't be re-ordered in the table (the first column only could have the tree in it). Additionally, there were some OS-specific issues, such as Windows only allowing an image in the first column.

You can use the TreeColumn now, which allows for other possibilities including column reordering.

Hello Rich,

I have changed all my TableTrees to Trees, but I am missing one feature:
I haven't found I thing like TableLayout to layout the columns of the Tree
without giving them fixed sizes.

TableLayout actually has many deficiencies and only sets the column widths
once - something you can easily do yourself in a resize listener:

tree.addControlListener(new ControlAdapter() {
public void controlResized(ControlEvent e) {
Rectangle area = tree.getClientArea();
TreeColumn[] columns = tree.getColumns();
if (area.width > 0 && columns[0].getWidth() == 0) {
columns[0].setWidth(area.width * 40 / 100);
columns[1].setWidth(area.width - columns[0].getWidth() -
4);
tree.removeControlListener(this);
}
}
});

Alternately, you can resize the columns dynamically as shown in this snippet
(written for Table but easily modified for Tree):
