Using the FontRegistry
<![CDATA[
FontData class is a lightweight class describing system fonts.
A FontData to a Font is analogous to an ImageDescriptor to an Image.
A FontData class describes the following properties of a Font:
name
height
style: combination of SWT.NORMAL, SWT.ITALIC, and SWT.BOLD
The Font itself is resource-based, i.e., if you create it, you must dispose of it.
You can use FontRegistry to manage allocation and disposal of the fonts.

text.setFont(fontRegistry.get("code"));
text.setForeground(display.getSystemColor(SWT.COLOR_BLUE));
text.setText("");
GridData gd = new GridData(GridData.FILL_BOTH);
gd.horizontalSpan = 2;
text.setLayoutData(gd);
Button executeButton = new Button(shell, SWT.PUSH);
executeButton.setText("Execute");
executeButton.setFont(fontRegistry.get("button-text"));
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
}
