[news.eclipse.platform.swt] Re: tree layout

["Veronika Irvine" <veronika_irvine@xxxxxxx>]

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);
        }
    }
});
