Usage

From source file:SWTUtils.java

/**
 * Create an awt font by converting as much information
 * as possible from the provided swt <code>FontData</code>.
 * <p>Generally speaking, given a font size, an swt font will
 * display differently on the screen than the corresponding awt
 * one. Because the SWT toolkit use native graphical ressources whenever
 * it is possible, this fact is platform dependent. To address
 * this issue, it is possible to enforce the method to return
 * an awt font with the same height as the swt one.
 *
 * @param device The swt device being drawn on (display or gc device).
 * @param fontData The swt font to convert.
 * @param ensureSameSize A boolean used to enforce the same size
 * (in pixels) between the swt font and the newly created awt font.
 * @return An awt font converted from the provided swt font.
 *///from   w w  w .j a  va 2  s . c  o  m
