Extra row and column in a SWT Table [message #550348] Fri, 30 July 2010 02:08 Go to next message

Hi,

I am trying to create a table without an extra row or column. I realize
that the jface TableColumnLayout can help with the column, but
I also want to eliminate that last row. Here is a snippet that shows a
simple attempt that does not work.

What do I need to do to shrink the table down to what I want? Do I need
to implement my own paint method to fix this?

Thanks

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.swt.widgets.TableItem;

public class TableQuestion {

public static void addTable(Composite comp) {

Table table = new Table(comp, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
table.setHeaderVisible(true);
table.setLinesVisible(true);

for (int i = 0; i < 3; ++i) {
TableColumn tc = new TableColumn(table, SWT.NONE);
tc.setText("Column " + i);
}

for (int i = 0; i < 4; ++i) {
TableItem item = new TableItem(table, SWT.NONE);
String[] iList = new String[] { "item0-" + i, "item1-" + i,"item2-"
+ i };
item.setText(iList);
}

for (int i = 0; i < 3; ++i) {
TableColumn tc = table.getColumn(i);
tc.pack();
}

table.pack();
}

public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
RowLayout layout = new RowLayout(SWT.VERTICAL);
layout.marginHeight = 10;
layout.marginWidth = 10;
shell.setLayout(layout);

addTable(shell);
Button button = new Button(shell, SWT.PUSH);
button.setText("Try It");

shell.pack ();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

Hi,

I just came across the problem/fix. The extra space is for the scrollbars. There will be no extra space when scrollbars appear. So if you don't need scrollbars in the table you can create the Table using SWT.NO_SCROLL and remove the extra space.

Thank you. Duh, why didn't I think of that.
