Hello,
after migrating to Eclipse 3.1M6, I switched my app from
TableTree(Viewer) to Tree(Viewer) because the forme has become
deprecated. However, I am now looking for a layout to attach to the Tree
in the same way that a TableLayout is attached to a Table. In
particular, I am looking for ways to specify the relative weight of the
columns, and the automatic resizing that is performed by TableLayout.
Can anybody help?
thanks,
christian

hmm, I dont think I understand the conclusion. Right now, Tree is not
able to fully replace TableTree, as there are no similar layout
facilites (in fact, there seem to be none). So, in order to avoid API
change, the only way would be to remove the deprecation IMO..

TableLayout is not really a satisfactory answer for Table or Tree. The idea
of TableLayout is probably going to be rethought post 3.1 and therefore it
does not make too much sense for a copy of TableLayout to be created for
Tree. The work being done in TableLayout can quite simply be done with a
resize listener. For example, the PropertySheet view does the following:
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);
}
}
});
