+    \class Q3PaintDeviceMetrics
+    \brief The Q3PaintDeviceMetrics class provides information about a
+    paint device.
+
+    \compat
+
+    Sometimes when drawing graphics it is necessary to obtain
+    information about the physical characteristics of a paint device.
+    This class provides the information. For example, to compute the
+    aspect ratio of a paint device:
+
+    \snippet doc/src/snippets/code/src_qt3support_painting_q3paintdevicemetrics.cpp 0
+
+    Q3PaintDeviceMetrics contains methods to provide the width and
+    height of a device in both pixels (width() and height()) and
+    millimeters (widthMM() and heightMM()), the number of colors the
+    device supports (numColors()), the number of bit planes (depth()),
+    and the resolution of the device (logicalDpiX() and
+    logicalDpiY()).
+
+    It is not always possible for Q3PaintDeviceMetrics to compute the
+    values you ask for, particularly for external devices. The
+    ultimate example is asking for the resolution of of a QPrinter
+    that is set to "print to file": who knows what printer that file
+    will end up on?
