Abstract

A presentation manager including a module for representing a graphical object on a page, the graphical object having a size and a placement on said page; a module for representing a container object that is associated with the page, the container object having a set of specified characteristics; a module for dragging the graphical object to another location on the page; and a module for linking the graphical object to the container object when the graphical object is dragged into the container object, wherein the linking module creates an active link to the container object when the graphical object is dragged into the container object, wherein the active link imposes the set of specified characteristics on the graphical object.

Claims

1. A method of managing a presentation for use with a computer having a display screen and a pointing device that controls the location of a pointer on said display screen said method comprising:

representing each page of a multi-page presentation, each of said pages defining a two-dimensional work area having contents that can be modified by a user when that page is displayed on said display screen;

representing a plurality of graphical objects that form part of the contents of a selected page of said multi-page presentation, each of said plurality of graphical objects having associated therewith a user-specified size and a user-specified location on said selected page, said user-specified locations of said graphical object having an x-coordinate and a y-coordinate which are user-selectable within a two-dimensional range of coordinates, each of said graphical objects appearing on-said display screen as a corresponding graphical image when said selected page is displayed on said screen and the corresponding graphical image of each of said graphical objects disappearing from said display screen when said selected page is removed from said display screen;

representing a container object that can be associated with said selected page, said container object having associated therewith a user-specified size and a user-specified location, said user-specified location of said container object being independent of said graphical objects and having an x-coordinate and a y-coordinate which are user-selectable within said two-dimensional range of coordinates, said container object having a set of user-specified visual characteristics associated therewith;

capturing a selected one of said plurality of graphical objects when said pointer has been moved to a location that lies on or within the selected graphical object;

dragging the captured graphical object to another location on said selected page;

releasing the captured graphical object at the other location; and

linking said released graphical object to said container object when said captured graphical object is released in said container object, wherein said linking step creates a link between said released graphical object and said container object and imposes the set of specified visual characteristics on said released graphical object, and when imposed on said released graphical object said set of specified visual characteristics dictates the visual appearance of the graphical image corresponding to the released graphical object.

2. The method of claim 1 further comprising the step of unlinking said released graphical object from said container object when said released graphical object is dragged out of said container object, wherein the graphical image corresponding to the unlinked graphical object is then free to take on visual characteristics that are independent of said set of specified visual characteristics.

3. The method of claim 1 wherein the user-specified location of said container object on said selected page is independent of any other container objects that are associated with said selected page.

4. The method of claim 1 wherein the work area of any given page is independent of the work area of any other page.

5. The method of claim 4 wherein said linking step generates said link by marking said released graphical object as being associated with said container object.

6. The method of claim 5 wherein said container object is a placement block and said set of specified visual characteristics includes size and location and wherein said linking step imposes only the size and location characteristics of said placement block on the graphical image corresponding to said released graphical object when said released graphical object is released into said placement block.

7. The method of claim 5 wherein said container object is a text block, wherein said set of specified visual characteristics includes size, location and preselected attributes and wherein said linking step imposes said set of specified visual characteristics on the graphical image corresponding to said released graphical object when said released graphical object is released onto said text block.

8. The method of claim 7 wherein said preselected attributes include one or more features selected from a group including typeface, font size, color of text, color of background, bullet style, appearance, indents, spacing, justification, and word wrap.

9. The method of claim 7 wherein said preselected attributes include one or more features selected from a group including border color, border width and border style.

10. The method of claim 5 further comprising highlighting said container object when said captured graphical object has entered said container object.

11. The method of claim 5 wherein said dragging step comprises:

representing the captured graphical object by an intransit object;

moving said in-transit object to another location on said selected page; and

releasing said in-transit object at the conclusion of a move.

12. The method of claim 11 wherein said moving step comprises:

determining whether said in-transit object has entered said container object; and

highlighting said container object when said determining step determines that said in-transit object has entered said container object.

13. The method of claim 12 further comprising unhighlighting a highlighted container object when said intransit object is released into the highlighted container.

14. The method of claim 11 wherein said linking step comprises:

detecting when said releasing step has released said in-transit object;

determining whether said in-transit object has entered said container object;

repositioning said captured graphical object into said container object in response to said releasing step releasing said in-transit object and if said determining step determines that said in-transit object has entered said container object, wherein said repositioning step imposes the set of specified visual characteristics on the graphical image corresponding to said captured graphical object.

15. The method of claim 14 wherein said linking step further comprises erasing said in-transit object in response to said releasing step releasing said in-transit object.

16. The method of claim 5 wherein said container object is on a different page from said plurality of graphical objects and wherein said method further comprises assigning said different page to said selected page so that said container object as associated with said selected page.

17. The method of claim 16 further comprising disassociating said different page from said selected page so that said different page is no longer assigned to said selected page and said container object is no longer associated with said selected page.

18. The method of claim 17 wherein said disassociating step further comprises making dormant any link that any of said plurality of graphical objects may have with said container object when said disassociating step disassociates said different page from said selected page.

19. The method of claim 5 further comprising displaying said selected page wherein said display step renders the graphical images corresponding to said plurality of graphical objects visible and it renders said container object visible only when said container object is associated with said selected page and when none of said graphical objects has an active link to said container object.

20. The method of claim 19 wherein said display step further comprises rendering said container object invisible when any one of said plurality of graphical object is dragged into said container object.
