A window object is a representation of an on-screen area on a display device that serves as a graphics destination.

Note
Objects or subclasses of this type can not be saved or restored.

Note on Window Size Limits

The OpenGL libraries IDL uses impose limits on the maximum size of a drawable area. The limits are device-dependent — they depend both on your graphics hardware and the setting of the RENDERER property. Currently, the smallest maximum drawable area on any IDL platform is 1280 x 1024 pixels; the limit on your system may be larger.
