Data processing device having event in non-windows desktop environment affecting window in desktop environment

A data processing device having multi-window functions wherein a plurality of windows are displayed on a screen and processing is carried out in each of said windows, comprising:

• a first processor for managing a desktop operation environment on said screen comprising windows generated on said screen;
• a second processor for managing a non-desktop area of said screen other than said windows;
• and
• an event manager for determining whether an event caused by an operation applied to said screen is for one of a first operation environment and a second operation environment, in accordance with whether the operation is applied with respect to one of said windows of the desktop operation environment and the non-desktop area of said screen other than said windows, and
• said second processor outputs to said first processor a request for generating a window of said second operation environment for event processing when an event is determined to be for said second operation environment by said event manager, and
• said first processor not only generates and controls a window of said first operation environment for event processing when an event is determined to be for said first operation environment by said event manager but also generates a window of said second operation environment in accordance with a request for generating a window of said second operation environment from said second processor.

An apparatus for processing data using a desktop environment comprising a plurality of windows on a screen, and a non-desktop environment comprising an area other than said windows on the screen, comprising:

• means for managing the desktop environment on the screen using a first processor;
• means for managing the non-desktop environment on the screen using a second processor;
• means for determining whether an event caused by an operation applied to said screen is for the desktop environment or the non-desktop environment;
• means for outputting a request for generating a window from the second processor to the first processor when the event is determined to be for the non-desktop environment;
• means for generating and controlling a window of the desktop environment using the first processor when the event is determined to be for the desktop environment, and also for generating a window of the non-desktop environment in accordance with the request for generating a window from the second processor.
