I think you'll find it easier to just draw the stuff:
public static void main(String[] args) {
final String string = "Bold text to vertically center";
final Display display = new Display();
Shell shell = new Shell(display);
shell.setBounds(10,10,400,200);
Canvas canvas = new Canvas (shell, SWT.NONE);
canvas.setBounds(10,10,300,100);
FontData[] data = canvas.getFont().getFontData();
for (int i = 0; i < data.length; i++) {
data[i].setStyle(data[i].getStyle() | SWT.BOLD);
}
Font newFont = new Font(display, data);
canvas.setFont(newFont);
canvas.addPaintListener(new PaintListener() {
public void paintControl(PaintEvent e) {
e.gc.setBackground(display.getSystemColor(SWT.COLOR_RED));
e.gc.fillRectangle(0,0,300,100);
Point size = e.gc.stringExtent(string);
e.gc.drawText(string, 0, (100 - size.y) / 2);
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
newFont.dispose();
display.dispose();
}
