This needs to be virtual? This class doesn't have virtual methods.

+
+  void SetVisible(bool visible);
+  bool IsVisible() const;
+
+  // Sets the window to fullscreen if 'fullscreen' is true. Otherwise it sets
+  // it as a normal window.
+  void SetFullscreen(bool fullscreen);
+  bool IsFullscreen() const;
+
+  // Returns a pointer to the parent window. NULL is this window doesn't have
+  // a parent.
+  WaylandWindow* GetParentWindow() const;

[tfarina, 2011/07/25 18:34:27]

The way we prefer is:

WaylandWindow* parent_window() const { return parent_window_; }

Yes, inlined here in the header file and with unix_hacker style ;)

+
+  WaylandWidget* GetWidget() const;

[tfarina, 2011/07/25 18:34:27]

Same thing here:

WaylandWidget* widget() const { return widget_; }

+  // Returns the pointer to the surface associated with the window.
+  // The WaylandWindow object owns the pointer.
+  wl_surface* GetSurface() const;

[tfarina, 2011/07/25 18:34:27]

And here.

+
+  void Configure(uint32_t time, uint32_t edges, int32_t x, int32_t y,
+                 int32_t width, int32_t height);
+
+ private:
+  // The widget that will process events for this window. This is not owned
+  // by the window.
+  WaylandWidget* widget_;
+  WaylandDisplay* display_;
+
+  // The native wayland surface associated with this window.
+  wl_surface* surface_;
+
+  // Whether the window is in fullscreen mode.
+  bool fullscreen_;
+
+  WaylandWindow* parent_window_;

Document this? I'd also move it near of widget_ and display_

+  // Position relative to parent window. This is only used by
+  // a transient window.
+  gfx::Point relative_position_;
+
+  DISALLOW_COPY_AND_ASSIGN(WaylandWindow);
+};
+
+}  // namespace ui
