+/*!
+    \class QEGLPlatformWindow
+    \brief Base class for EGL-based platform window implementations.
+    \since 5.2
+    \internal
+    \ingroup qpa
+
+    Lightweight class providing some basic platform window operations
+    and interfacing with QEGLPlatformBackingStore.
+
+    Almost no QPlatformWindow functions are implemented here. This is
+    intentional because different platform plugins may use different
+    strategies for their window management (some may force fullscreen
+    windows, some may not, some may share the underlying native
+    surface, some may not, etc.) and therefore it is not sensible to
+    enforce anything for these functions.
+
+    \note Subclasses are responsible for invoking this class'
+    implementation of create(). When using QEGLPlatformScreen, the
+    subclasses of this class are expected to utilize the window stack
+    management functions (addWindow() etc.) provided there.
