Java SWT - StyledText how to show text using monospaced font

Is there any way to force StyledText widget to show text using monospaced font? It's not a problem of used font - I have tried 'Monospace', 'Courier', 'System', 'Fixedsys' and other monospaced fonts... Normal Text widget shows text with monospaced font defaultly ('Fixedsys' font tested).

Thanks in advance for help!

You can get a monospaced font with the methods shown in the answers to this question:

SWT - OS agnostic way to get monospaced font

Then simply call StyledText#setFont(Font):

public static void main(String[] args)
{
    Display display = new Display();
    Shell shell = new Shell();
    shell.setText("StackOverflow");
    shell.setLayout(new FillLayout());

    StyledText text = new StyledText(shell, SWT.BORDER | SWT.MULTI);
    text.setFont(JFaceResources.getFont(JFaceResources.TEXT_FONT));
    text.setText("|i|m|\n|m|i|");

    shell.pack();
    shell.setSize(200, 100);
    shell.open();

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

Looks like this:
