Abstract

In response to a user pasting data within a clipboard to a desktop for an object management facility, a new object for the data is created. The data is placed within the new object, and an icon is displayed on the desktop for the new object. When the data is text, the new object is created to be of a type which contains text. When the data is bitmapped, the new object is created to be of a type which contains bitmaps. The data is placed in the clipboard, for example, in response to a Cut command or in response to a Copy command from an application process originally processing the data. The data can reformatted, for example, before exporting the data from the application process, before importing the data to the new object or after importing the data to the new object. Also, in response to a user selecting a first object and issuing a conversion command, classes of objects into which the first object may be converted are displayed to the user. Upon the user selecting a class of objects into which the first object is to be converting, the first object is converted into a new object of the selected class of objects. The new object is created, data from the first object is extracted and sent to the new object. The data may be converted to a format usable by the first object, by the new object or by the object management facility.

Claims

1. A computer implemented method within an object management facility comprising the step of:

(a) in response to a user pasting data within a clipboard to a window controlled by the object management facility, performing the following substeps;

(a.1) creating, by the object management facility, a new object for the data;

(a.2) placing the data within the new object; and

,

(a.3) displaying by the object management facility, an icon for the new object.

2. A computer implemented method as in claim 1 wherein substep (a.1) includes the following substeps:

when the data is text, creating the new object to be of a type which contains text; and

,

when the data is other than text, searching for a class of object that can accept the data.

3. A computer implemented method as in claim 1 additionally comprising the following step executed before step (a):

(b) placing the data in the clipboard in response to a Cut command from an application process.

4. A computer implemented method as in claim 3 wherein step (b) includes reformatting the data before exporting the data from the application process.

5. A computer implemented method as in claim 1 additionally comprising the following step executed before step (a):

(b) placing the data in the clipboard in response to a Copy command from an application process.

6. A computer implemented method as in claim 5 wherein step (b) includes reformatting the data before exporting the data from the application process.

7. A computer implemented method as in claim 1, wherein substep (a.2) includes:

importing the data into the new object using a method by which the new object changes the format of the data.

8. A computer implemented method within an object management facility comprising the steps of:

(a) in response to a user selecting a paste command while a desktop for the object management facility is active, performing the following substeps;

(a.1) if there is no data on a clipboard, doing nothing;

(a.2) if an object format for data on the clipboard cannot be provided, doing nothing;

(a.3) if there is data ion the clipboard and an object format for data can be provided, performing the following substeps;

(a.3.1) creating, by the object management facility, a new object for the data;

(a.3.2) placing the data within the new object; and

,

(a.3.3) displaying an icon on the desktop for the new object.

9. A computer implemented method as in claim 8 wherein substep (a.3.2) includes:

importing the data into the new object using a method by which the new object changes the format of the data.

10. A computer implemented method within an object management facility comprising the step of:

(a) in response to a user selecting a first object and issuing a conversion command, performing the following substeps;

(a.1) displaying, to the user, classes of objects into which the first object may be converted; and

,

(a.2) upon the user selecting a class of objects into which the first object is to be converted, converting the first object into a new object of the selected class of objects.

11. A computer implemented method as in claim 10 wherein step (a.2) includes the following substeps:

(a.2.1) creating, by the object management facility, the new object;

(a.2.2) extracting data from the first object;

(a.2.3) sending the data extracted in substep (a.2.2) to the new object; and

,

(a.2.4) converting, by the new object, the data into a format usable by the new object.

12. A computer implemented method as in claim 11 wherein the converting in substep (a.2.4) is performed using an ACCEPT_-- DATA method.

13. A computer implemented method as in claim 10 wherein step (a.2) includes the following substeps:

(a.2.1) creating, by the object management facility, the new object;

(a.2.2) converting, by the first object, data within the first object into converted data with a format usable by the new object;

(a.2.3) extracting the converted data from the first object; and

,

(a.2.4) sending the converted data to the new object.

14. A computer implemented method as in claim 13 wherein the converting in substep (a.2.2) is performed using a RENDER_-- DATA method.

15. A computer implemented method as in claim 10 wherein step (a.2) includes the following substeps:

(a.2.1) creating, by the object management facility, the new object;

(a.2.2) extracting the converted data from the first object;

(a.2.3) converting, by the object management facility, the data extracted in step (a.2.2) into converted data with a format usable by the new object; and

,

(a.2.4) sending the converted data to the new object.

16. A computer implemented method as in claim 15 wherein the converting in substep (a.2.3) is performed using a CONVERT_-- DATA method.

17. A computer implemented method within an operating system process comprising the step of:

(a) in response to a user selecting data from a file and designating a window controlled by the operating system process in which to place the data, performing the following substeps;

(a.1) creating, by the operating system process, a new data file for the data;

(a.2) placing the data within the new data file; and

,

(a.3) displaying, by the operating system process, an icon for the new data file appearing within the window.

18. A computer implemented method as in claim 17 wherein substep (a.2) includes:

importing the data into the new data file using a method by which the new data file changes the format of the data.
