A multimedia system includes a multimedia device control program having a plurality of application program selectable controls for controlling operation of a like plurality of different classes of multimedia devices. Each class has a different set of controllable device functions or attributes. In response to selection of a class by an application program, a unique control panel is created in a user interface for controlling operation of a device. The selected control performs all of the processing actions necessary to control the device in response to user selections on the interface, without involvement of the application program in such actions. The multimedia control program includes a plurality of panel templates from which control panels are created in a control screen. Each panel has a plurality of controllers that can manipulated by a user to control a corresponding function of a multimedia device. The templates provide a consistent interfaces having a common look and feel. The multimedia control program also includes a plurality of class control programs one or more of which are selected by an application program to be attached to a like number of multimedia devices for controlling operation of the devices in response to user selections on the user interface, thereby relieving the application program of performing the necessary control functions.

A technique is described for managing windows in a display system. The window manager allows a user to mark an area on the display to define the dimensions and contents of a resized window. All non-hidden text and attributes within the enclosed area are incorporated into the resized window; however, the original windows do not lose their original characteristics. The marked area may span multiple windows, so multiple windows may be incorporated into the newly resized window. For each position within the newly resized window, a check is made for a window below. If no window exists below this position, the default, or background, character and attribute are incorporated into the newly resized window. If there exists a window below, a determination is made as to whether the window below is visible or hidden. If hidden, the system continues to look for a visible window until no further window is found below, at which point the default character and attribute are incorporated into the newly resized window. When a visible window is found below the newly resized window, the character and attribute from its corresponding position are read and incorporated into the newly resized window. This process continues until all of the information is processed from the marked area. In this manner, a window can be enlarged to incorporate the contents of several windows by enclosing several windows in the marked area.
