+Changing Windows
+============================
+
+The ``WindowProperties`` class can be used to alter the behavior of existing windows. If "base" is your showbase instance, change properties of your window like this:
+        
+.. only:: python
+
+   .. code-block:: python
+        from panda3d.core import WindowProperties
+        # ...
+        wp = WindowProperties()
+        wp.setSize(1920),1080)
+        wp.setFullscreen(True)
+        wp.setTitle("My Awesome Game")
+        base.win.requestProperties(wp)
+
+The API for lists ``WindowProperties`` some other functions for common operations, so if you are doing this, it is worth browsing what is available.
