Abstract

A method is described for editing graphic objects in an interactive draw graphic system which selectively displays a menu of available editing actions in response to operation of one mouse button by the operator and allows the operator to cursor select the specific edit action from the menu to be made active by operating a second mouse key. The operator may also cursor select the object to be edited by operation of the second mouse key. Once the editing action is selected and made active, the menu is hidden (not displayed) and the editing action remains active in the system until positive steps are taken by the operator to either terminate the edit function or change the active editing action. The operator, therefore, does not have to return to the selection process after each specific editing operation. The previous editing operation is implied for the next edit operation.

Claims

1. A method of editing displayed graphic objects in an interactive draw graphic system having (a) a display device with an operator positionable cursor for displaying to an operator graphic objects to be edited, and (b) an input device having means to control the position of said cursor on the display device and first and second two position keys for providing to said system three different control signals, said method comprising the steps of:

(A) displaying to said operator a menu of available graphic editing actions in response to a first said control signal being sent from said input device to said system when said operator presses and releases said first key,

(B) establishing one of said available editing actions as the active editing action including the steps of;

(1) positioning said cursor in a first position relative to said one editing action, and

(2) sending a second said control signal from said input device to said system when said second key is pressed and released by said operator while said cursor is in said first position, and

(C) selecting one of said objects to be edited by said active editing action including the steps of;

(1) positioning said cursor in a second position relative to said one said object, and

(2) sending a third control signal from said input device to said system in response to said operator pressing said second key when said cursor is at said second position and holding said second key pressed until said active editing action on said selected object is completed,

whereby said operator may continue editing the same or another said object with said active editing action by repeating step (C) without the necessity of repeating steps (A) and (B).

2. The method recited in claim 1 in which said step of displaying said menu displays said menu in a predetermined positional relationship with respect to said cursor.

3. The method recited in claim 2 in which said step of establishing includes the step of maintaining the selected editing action active until a different editing action is established or said editing operation is terminated.

4. The method recited in claim 3 further including the step of modifying the appearance of said cursor to reflect the editing action that is established as said active editing action.

5. The method recited in claim 4 further including the step of hiding said menu from said operator after an editing action has been established as said active editing action.

6. The method recited in claim 5 further including the steps of terminating said editing action on said selected object by releasing said second key , and editing a second said object with the active editing action without repeating said step of establishing.

7. The method recited in claim 6 in which said system includes a keyboard having an edit operation end key, further including the step of terminating said editing operation when said operator presses said end key.
