+The pvr2d.h & wsegl.h in the powervr directory are required for building
+the PowerVR plugin on Qt for Embedded Linux. These headers are for SGX
+based SoCs, but may also work on MBX SoCs.

+    that support it. The currently supported platforms are Mac OS X and Windows CE. On these platforms
+    if this property is true, the menubar is used in the native menubar and is not in the window of
+    its parent, if false the menubar remains in the window. On other platforms the value of this
+    attribute has no effect.
+
+    The default is to follow whether the Qt::AA_DontUseNativeMenuBar attribute
+    is set for the application. Explicitly settings this property overrides
+    the presence (or abscence) of the attribute.
