Hi,

I've been trying to get rid of the white line that goes across the shell
in the below program when adding a separator. I have not luck for the
past days. Please advise. Greatly appreciated!

import org.eclipse.swt.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.browser.*;
import org.eclipse.swt.graphics.Font;
import org.eclipse.swt.graphics.FontData;

public class MySeparator {
public static void main(String [] args) {
Display display = new Display();
final Shell shell = new Shell(display, SWT.TOOL);

shell.setBackground(display.getSystemColor(SWT.COLOR_INFO_BA CKGROUND));

shell.setForeground(display.getSystemColor(SWT.COLOR_INFO_FO REGROUND));
GridLayout gridLayout = new GridLayout(1, false);
gridLayout.marginHeight = -2;
gridLayout.marginWidth = -2;
shell.setLayout(gridLayout);

GridData data = new GridData();
final Browser browser = new Browser(shell, SWT.NONE);
data = new GridData(GridData.BEGINNING | GridData.FILL_BOTH);
data.horizontalSpan = 1;
browser.setLayoutData(data);

// Horizontal separator line
Label separator= new Label(shell, SWT.SEPARATOR |
SWT.HORIZONTAL | SWT.LINE_SOLID);
data = new GridData(GridData.FILL_HORIZONTAL);
separator.setLayoutData(data);

// Status field label
Label statusField= new Label(shell, SWT.NONE);

statusField.setForeground(display.getSystemColor(SWT.COLOR_W IDGET_DARK_SHADOW));

statusField.setBackground(display.getSystemColor(SWT.COLOR_I NFO_BACKGROUND));

Font font= statusField.getFont();
FontData[] fontDatas= font.getFontData();
for (int i= 0; i < fontDatas.length; i++)
{
fontDatas[i].setHeight(fontDatas[i].getHeight() * 9 / 10);
}
Font statusTextFont = new Font(statusField.getDisplay(),
fontDatas);
statusField.setFont(statusTextFont);

data = new GridData(GridData.HORIZONTAL_ALIGN_END);
statusField.setLayoutData(data);
statusField.setText("Status text");

// Nothing gets displayed!
browser.setText("<html><body style=\"overflow:auto;\"
text=\"#000000\" bgcolor=\"#ffffe1\">TEST</body></html>");

shell.open();

// Same if I set url! Nothing gets displayed
// browser.setUrl("www.eclipse.org");
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

Actually found out...Once I set the Url of the browser to
http://www.eclipse.org. I can see that the white line is actually the
vertical space (default to 5 pixels) of the browser. So, I need to set
the shell's vertical spacing to 0. That did the trick! :-)
