Abstract

A method and system for resizing edit controls of a graphical user interface that in previous systems were of a fixed size. The preferred steps of the resize operation entail moving a mouse cursor over a designated portion of the edit control, activating a mouse button, and dragging a border of the edit control to a new location on the user interface. Upon recognition of these steps, an operating system generates messages indicating that a resize operation is requested. An application retrieves the message from the operating system and sends the message to an application edit control code. Before the message reaches the application edit control code, it is hooked by resize edit control code, which resizes the edit control in response to the messages.

In this way, edit controls that in previous systems were fixed in size can, under the preferred embodiment, be resized. Subsequent use of the edit control after resizing allows data to be received and displayed in an improved manner.

Claims

1. A method executed in a computer system for resizing an edit control in a specified direction, the edit control displaying data sent to the edit control, the edit control containing a resize portion, the computer system including a display device which displays the edit control, an input device for entering the data that is sent to the edit control for display, and a storage device, edit control code stored in the storage device for processing data entered in the edit control, and resizing code stored in the storage device for processing requests to resize the edit control, the resizing code being associated with the edit control code so that the resizing code receives the data sent to the edit control code before the edit control code receives the data, the method comprising the steps of:

receiving the data sent to the edit control by the input device;

determining that the received data requests a resizing of the edit control in the specified direction;

when the edit control is enabled to change size in the specified direction,

resizing the edit control on the display device in the specified direction in response to the determining that the received data requests resizing; and

providing a means for a user of the computer system to disable resizing of the edit control beyond a maximum size to prevent conflict with other interface elements.

2. The method of claim 1, further comprising the step of entering data in the edit control, said step including:

positioning a cursor on the resize portion of the edit control using the input device; and

dragging the input device to move the cursor to indicate the request to resize the edit control.

3. The method of claim 1 wherein resizing of the edit control is disabled by a user of the computer system in a specified direction.

4. The method of claim 3, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

5. The method of claim 1, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

6. A method executed in a computer system for resizing an edit control in a specified direction, the edit control displaying data sent to the edit control, the edit control including a resize portion, the computer system including a display device which displays the edit control, an input device for entering the data that is sent to the edit control for display, and a storage device which stores edit control code for processing data entered in the edit control and resizing code for processing requests to resize the edit control, the resizing code being associated with the edit control code so that the resizing code receives the data sent to the edit control code before the edit control code receives the data, the method comprising the steps of:

receiving the data sent to the edit control by the input device;

determining that an association exists between the resizing code and the edit control code;

determining that the received data requests a resizing of the edit control in the specified direction;

when the edit control is enabled to change size in the specified direction,

resizing the edit control on the display device in the specified direction with the resizing code in response to the determination that the received data requests resizing; and

providing a means for a user of the computer system to disable resizing of the edit control beyond a maximum size to prevent conflict with other interface elements.

7. The method of claim 6, wherein the step of resizing the edit control includes the step of displaying on the display device a ghost frame which outlines where the edit control will be resized.

8. The method of claim 6, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

9. The method of claim 6, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control in a specified direction.

10. The method of claim 9, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

11. The method of claim 6, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control in both a vertical and a horizontal direction.

12. The method of claim 11, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

13. A method executed in a computer system for resizing an edit control in a specified direction, the edit control displaying data sent to the edit control, the edit control including a resize portion, the computer system including a display device which displays the edit control, an input device for entering the data that is sent to the edit control for display, and a storage device which stores edit control code for processing data entered in the edit control, the method comprising the steps of:

providing resizing code for processing requests to resize the edit control;

associating the resizing code with the edit control code so that the resizing code receives the data sent to the edit control code before the edit control code receives the data;

receiving the data sent to the edit control by the input device;

when the received data requests a resizing of the edit control in the specified direction,

sending the received data to the resizing code;

resizing the edit control on the display device in the specified direction in response to the received data; and

providing a means for a user of the computer system to disable resizing of the edit control beyond a maximum size to prevent conflict with other interface elements.

14. The method of claim 13, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control in a vertical direction.

15. The method of claim 14, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

16. The method of claim 13, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control in the horizontal direction.

17. The method of claim 16, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control below a minimum size.

18. The method of claim 13, wherein the method further comprises the step of providing a means for a user of the computer system to disable resizing of the edit control in both the vertical and horizontal direction.
