I'm not all too clear on how the TableLayout is suppose to format the
columns in a Table. I've tried setting the weight of the columns using
ColumnWeightData but I haven't got very good results. I expected the columns
to fill the size of the table but instead it packs everything together to
try to take up as little space as possible. Is there any nice ways of making
the columns span the space nicely by default?
Here's some code snippets of what I did.
private String[] columnHeaders = { "Server",
"Something",
"Info"
};
private ColumnLayoutData[] columnLayouts = {
new ColumnWeightData(20,200),
new ColumnWeightData(10,100),
new ColumnWeightData(10,100)
};
private void createColumns() {
TableLayout layout = new TableLayout();
table.setLayout(layout);
table.setHeaderVisible(true);
for (int i = 0; i < columnHeaders.length; i++) {
TableColumn tc = new TableColumn(table, SWT.NONE, i);
tc.setText(columnHeaders[i]);
tc.setResizable(columnLayouts[i].resizable);
layout.addColumnData(columnLayouts[i]);
//TODO add a listener for header sorting
//tc.addSelectionListener(headerListener);
}
}
Any suggestions would be appreciated...
Thanks,
James

If you are talking about table primary column layout, it works OK. The
problem appears when you resize table (at least for Eclipse up to
version 2.1.1): it doesn't want to resize column using specified
weights. That's because TableLayout works only one time. Comment in
TableLayout class (if I remember it right) says that it was done on
purpose to avoid some flickering problems. To solve this problem I use
resize table listener for the table which modifies column sizes using
TableColumn.setWidth() method on the base of their weights.

Ok, well I'm using Eclipse 3.0 if that matters. And I'm manualy setting the
column widths using setWidth upon creation now. I just thought the whole
point of the TableLayout was to at least do that for you. Oh well, and
thanks for the tip about listening for resizing that should help me get the
proper effect.
