Abstract

Claims (49)

1. A method for modifying a system-defined ListView control on a compute device, the method comprising:

associating, on the compute device, a programmer-defined control with the system-defined ListView control such that the programmer-defined control is configured to intercept one or more messages for the system-defined ListView control;

intercepting, by the programmer-defined control, a first message for the system-defined ListView control and associated with a call to render an interface associated with the system-defined ListView control;

in response to intercepting the first message:

preventing the interface associated with the system-defined ListView control from rendering; and

rendering an interface associated with the programmer-defined control;

intercepting, by the programmer-defined control, a second message for the system-defined ListView control and associated with an interaction of a user with the rendered interface associated with the programmer-defined control;

determining that the second message requires modified functionality different from functionality provided by the system-defined ListView control, the functionality provided by the system-defined ListView control including presenting table contents without sort functionality and the modified functionality including presenting the table contents with sort functionality such that the table contents are sortable; and

in response to determining that the second message requires the modified functionality:

sending a third message to the system-defined ListView control such that the system-defined ListView control provides the functionality; and

providing using the programmer-defined control the modified functionality in addition to the functionality provided by the system-defined ListView control.

2. The method of claim 1 , further comprising, in response to determining that the second message requires the modified functionality, modifying the second message to produce the third message that is sent to the system-defined ListView control.

3. The method of claim 1 , wherein associating the programmer-defined control with the system-defined ListView control includes defining features of the programmer-defined control based on features of the system-defined ListView control.

4. The method of claim 1 , wherein the compute device is a hand-held device.

5. The method of claim 1 , wherein associating the programmer-defined control with the system-defined ListView control includes generating the programmer-defined control including one or more wrapped features of the system-defined ListView control.

6. The method of claim 1 , wherein the programmer-defined control is associated with the system-defined ListView control at run-time.

7. The method of claim 1 , wherein the programmer-defined control is associated with the system-defined ListView control without inheritance.

8. A compute device configured for modifying a system-defined ListView control, comprising:

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable to:

associate a programmer-defined control with the system-defined ListView control such that the programmer-defined control is configured to intercept one or more messages for the system-defined ListView control;

intercept a first message for the system-defined ListView control and associated with a call to render an interface associated with the system-defined ListView control;

in response to intercepting the first message:

prevent the interface associated with the system-defined ListView control from rendering; and

render an interface associated with the programmer-defined control in place of the interface associated with the system-defined ListView control;

intercept a second message for the system-defined ListView control and associated with an interaction of a user with the rendered interface associated with the programmer-defined control;

determine that the second message requires modified functionality different from functionality provided by the system-defined ListView control, the functionality provided by the system-defined ListView control including presenting table contents without sort functionality and the modified functionality including presenting the table contents with sort functionality such that the table contents are sortable;

in response to determining that the second message requires the modified functionality:

discard the second message;

perform an operation based on the modified functionality independent of the system-defined ListView control to produce an output; and

provide the output to the user.

9. The compute device of claim 8 , wherein the instruction executable to associate the programmer-defined control with the system-defined ListView control includes an instruction executable to define features of the programmer-defined control based on features of the system-defined ListView control.

10. The compute device of claim 8 , wherein the compute device is a hand-held device.

11. The compute device of claim 8 , wherein the programmer-defined control is associated with the system-defined ListView control at run-time.

12. A non-transitory, tangible computer-readable medium for modifying a system-defined ListView control, comprising executable instructions to:

associate a programmer-defined control with the system-defined ListView control without inheritance such that the programmer-defined control is configured to intercept one or more messages for the system-defined ListView control;

intercept a first message for the system-defined ListView control and associated with a call to render an interface associated with the system-defined ListView control;

in response to intercepting the first message:

prevent the interface associated with the system-defined ListView control from rendering; and

render an interface associated with the programmer-defined control in place of the interface associated with the system-defined ListView control;

intercept a second message for the system-defined ListView control and associated with an interaction of a user with the interface associated with the rendered interface associated with the programmer-defined control;

determine that the second message requires sort functionality not included in functionality provided by the system-defined ListView control;

in response to determining that the second message requires the sort functionality:

send a third message to the system-defined ListView control such that the system-defined ListView control provides table contents; and

map the table contents provided by the system-defined ListView control to sortable locations of a table such that the table contents are sortable.

13. The non-transitory, tangible computer-readable medium of claim 12 , wherein the executable instruction to associate the programmer-defined control with the system-defined ListView control includes an executable instruction to define features of the programmer-defined control based on features of the system-defined ListView control.

14. The non-transitory, tangible computer-readable medium of claim 12 , wherein the programmer-defined control is associated with the system-defined ListView control at run-time.

15. The non-transitory, tangible computer-readable medium of claim 12 , further comprising executable instructions to: in response to determining that the second message requires the sort functionality, modifying the second message to produce the third message.
