memory-bitmap-not-created

This condition will be signaled if an error occurs when creating the backing-store memory bitmap for a window. This typically indicates that not enough memory was available to create the memory bitmap. This may happen when creating a bitmap-pane if the page-width or page-height is very large, or when creating other windows if the double-buffered property is true and the window itself is very large.

An application could handle this situation by trapping this condition when calling make-window. The condition could also be signaled when resizing a double-buffered window with functions such as resize-window or (setf exterior), or when increasing the page size of a bitmap-pane with set-page-size.

This condition is a subclass of error.
