[news.eclipse.platform.swt] Re: TableColumn pack problem

[Robin Wilson <robinwilson@xxxxxxx>]

I'm using Eclipse Version: 3.0.0 on Windows XP. This snippet illustrates 
another problem I'm having. The first time the table is shown, there is 
extra space after the last column that looks like it's wide enough for a 
 scroll bar. Then as you press the button, the last column grows everytime.

Here's my snippet:

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
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 TableColumnProblemExample {
	public static void main(String[] args) {
		Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setText("Table Column Pack");
		GridLayout vertical = new GridLayout();
		vertical.numColumns = 1;
		shell.setLayout(vertical);
		final Table table = new Table(shell, SWT.SINGLE);
		table.setHeaderVisible(true);
		table.setLinesVisible(true);
		final TableColumn col1 = new TableColumn(table,SWT.CENTER);
		col1.setText("Column 1");
		final TableColumn col2 = new TableColumn(table,SWT.CENTER);
		col2.setText("Column 2");
		col1.pack();
		col2.pack();
		Button button = new Button(shell, SWT.PUSH);
		button.setText("Fill Data");
		button.addSelectionListener( new SelectionAdapter() {
			public void widgetSelected(SelectionEvent event) {
				//table.layout(true);
				table.setRedraw(false);
				table.removeAll();
				String [] data1 = { "1", "2" };
				String [] data2 = { "3", "4" };
				TableItem item1 = new TableItem(table, SWT.NONE);
				item1.setText( data1 );
				TableItem item2 = new TableItem(table, SWT.NONE);
				item2.setText( data2 );
				col1.pack();
				col2.pack();
				shell.pack();
				table.setRedraw(true);
			}
		});
		
		shell.pack();
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
	}
}
