For example, to compute the -aspect ratio of a paint device: -<p> <pre> - TQPaintDeviceMetrics pdm( myWidget ); - double aspect = (double)pdm.<a href="#widthMM">widthMM</a>() / (double)pdm.<a href="#heightMM">heightMM</a>(); - </pre> - -<p> TQPaintDeviceMetrics contains methods to provide the width and -height of a device in both pixels (<a href="#width">width</a>() and <a href="#height">height</a>()) and -millimeters (<a href="#widthMM">widthMM</a>() and <a href="#heightMM">heightMM</a>()), the number of colors the -device supports (<a href="#numColors">numColors</a>()), the number of bit planes (<a href="#depth">depth</a>()), -and the resolution of the device (<a href="#logicalDpiX">logicalDpiX</a>() and -<a href="#logicalDpiY">logicalDpiY</a>()). -<p> It is not always possible for TQPaintDeviceMetrics to compute the -values you ask for, particularly for external devices.
