Abstract

Theme changes for a custom graphical element are facilitated by providing a mechanism for storing theme specific data for the custom graphical element, providing a software object, independent of the custom graphical element, that monitors theme change events and, in response to a new theme being selected, the software object causing the custom graphical element to be redrawn according to the new theme. The custom graphical element may be graphical portions of a custom control, or a custom control itself. Switching to a new theme for an integrated graphical unit may be provided by marking for redrawing all of the graphical elements of the integrated graphical unit, traversing the elements, and redrawing each element that is marked. There may be provided a directory of theme files and, in each theme file, theme specific information indicating visual appearance of graphical elements.

Claims

1. A method of facilitating theme changes for a custom graphical element, comprising:

providing a mechanism for storing theme specific data for the custom graphical element;

providing a software object, independent of the custom graphical element, that monitors theme change events; and

in response to a new theme being selected, the software object causing the custom graphical element to be redrawn according to the new theme.

2. A method, according to claim 1, wherein the custom graphical element is graphical portions of a custom control.

3. A method, according to claim 1, wherein providing a mechanism for storing theme specific data includes providing a directory containing a plurality of theme files.

4. A method, according to claim 3, wherein each of the theme files corresponds to a particular theme.

5. A method, according to claim 3, wherein each of the theme files is a resource dictionary containing entries indicating visual appearance of graphical elements according to a particular theme.

6. A method, according to claim 1, further comprising:

in response to there being no specific information indicating visual appearance of the custom graphical element according to the new theme, redrawing the custom graphical element according to a fallback theme.

7. A method, according to claim 1, wherein the custom graphical element is part of an integrated graphical unit.

8. A method, according to claim 7, wherein the integrated graphical unit corresponds to a window.

9. A computer readable medium having computer executable instructions for performing the steps recited in claim 1.

10. A system having at least one processor that performs the steps recited in claim 1.

11. A method of switching to a new theme for an integrated graphical unit, comprising:

marking for redrawing all of the graphical elements of the integrated graphical unit;

traversing the elements; and

redrawing each element that is marked.

12. A method, according to claim 11, wherein at least one of the elements is a custom graphical element.

13. A method, according to claim 12, wherein at least one of the custom graphical elements is graphical portions of a custom control.

14. A method, according to claim 11, wherein redrawing each element includes accessing theme specific data.

15. A method, according to claim 14, wherein the theme specific data includes a directory containing a plurality of theme files and wherein each of the theme files corresponds to a particular theme.

16. A method, according to claim 14, wherein each of the theme files is a resource dictionary containing entries indicating visual appearance of elements according to a particular theme.

17. A computer readable medium having computer executable instructions for performing the steps recited in claim 11.

18. A system having at least one processor that performs the steps recited in claim 11.

19. A method of providing theme specific data for representing graphical elements, comprising:

providing a directory of theme files; and

providing, in each theme file, theme specific information indicating visual appearance of graphical elements.

20. A method, according to claim 19, further comprising:

in response to there not being theme specific data for a particular graphical element for a particular theme, using data from a fallback theme for the particular graphical element.
