A method and apparatus for manipulation of data in a computer-controlled display system. A user may select data from a first application program and drag it to an area on the computer system display representing a third application program. The first application program creates a series of formats into which the data may be provided and, in some instance, the data itself. Moreover, a second process appends to that list of formats a series of formats that it can provide the data in. Then, upon receipt of the list of formats and/or data of the first item, the third process can request the data in any of the formats from either the first or second processes, if required.

Method and apparatus for transferring data by type according to data

A method and apparatus for transferring control between application programs. A messaging means is provided which allows a first application program to indicate to the messaging means that a second application program should assume control. The messaging means receives the message and performs an orderly shutdown of the first application program and messages the second application program that it should commence operation. Upon valid and proper operation of the second application program, the first application program is caused to be suspended, and the second application program is invoked.

Method and apparatus for improved application program switching on a

A method and apparatus for improved user interaction and feedback on a computer system display. Interapplication dragging upon a user interface display is provided allowing a user to select a first item in a first window and move that first item to a second window which is under control of second process. Feedback is provided in the second window under control of the second process if the second application program can accept the data. In addition, other improved user interface actions are described, such as improved selection feedback, improved navigation, and improved completion feedback.

Method and apparatus for improved feedback during manipulation of data

A method and apparatus for selecting data in an application which is not a currently active context. The method comprises a user selecting information within a window under control of a first application program and moving the information to a second window under control of an active application program. This operation is performed providing a simple select, drag-and-drop operation. The active application program can arbitrate and communicate with a handler installed for the first application program to cause data from the first application program to be provided without activating the first application program.
