SWT table row mousehandler and checkbox detection

Question

When clicking a row a window pops up.

When clicking the cell in the first column nothing happens because a checkbox is located in the first column and a mouselistener detects the cell in the first column.

But selecting the checkbox the window pops up again.

How can i prevent the window popping up when selecting the checkbox?

Alright, found a solution.

The problem is, that there is no way (that I'm aware of) which will return the bounds of the checkbox. However, since the checkbox will always be the first thing in the table (if you use a Table with SWT.CHECK), you can simply check if the click event is to the left of the first cell.

I took the liberty to "optimize" some of your other code (my subjective opinion):

public static void main(String args[])
{
    Display display = new Display();
    final Shell shell = new Shell(display, SWT.BORDER | SWT.PRIMARY_MODAL | SWT.RESIZE);
    shell.setText(" Test table ");
    shell.setLayout(new GridLayout(1, true));

    final Table table = new Table(shell, SWT.BORDER | SWT.CHECK | SWT.V_SCROLL | SWT.FULL_SELECTION);
    table.setHeaderVisible(true);
    table.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));

    for(int col = 0; col < 5; col++)
    {
        new TableColumn(table, SWT.NONE).setText("column " + col);
    }
    for (int row = 0; row < 10; row++)
    {
        TableItem item = new TableItem(table, SWT.NONE);

        for(int col = 1; col < table.getColumnCount(); col++)
        {
            item.setText(col, "cell " + row + " " + col);
        }
    }
    for(int col = 0; col < table.getColumnCount(); col++)
    {
        table.getColumn(col).pack();
    }

    Button close = new Button(shell, SWT.PUSH);
    close.setText("Done");
    shell.setDefaultButton(close);
    close.setLayoutData(new GridData(SWT.FILL, SWT.END, true, false));

    close.addListener(SWT.Selection, new Listener()
    {
        @Override
        public void handleEvent(Event e)
        {
            shell.dispose();
        }
    });
    table.addListener(SWT.MouseUp, new Listener()
    {
        public void handleEvent(Event e)
        {
            if (table.getItemCount() > 0)
            {
                Rectangle rect = table.getItem(new Point(e.x, e.y)).getBounds(0);
                if (rect.contains(new Point(e.x, e.y)) || e.x <= rect.x)
                    System.out.println("first column or checkbox clicked");
                else
                    System.out.println("other column clicked");
            }
        }
    });

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