Abstract

A method includes creating a first window to receive video which at least partially overlaps a second window on a region of overlap of the display. Pixels of the first window are set to a chroma color. Background pixels of the second window in the region of overlap are also set to the chroma color, The second window is configured to draw after the first window.

Claims

1. A method comprising:

creating a first window to display dynamic video content which at least partially overlaps a second window on a region of overlap on a display, wherein the first window further comprises a first non-overlap region, and the second window further comprises a second non-overlap region and at least one application element;

setting the pixels of the first window to a chroma color;

setting background pixels of the second window in the region of overlap to the chroma color; and

configuring the second window to draw the at least one application element after the first window has displayed at least a portion of the dynamic video content.

2. The method of claim 1 further comprising:

configuring the first and second windows as children of a common parent window.

3. The method of claim 1 further comprising:

configuring the second window to receive user interface events.

4. The method of claim 1 in which configuring the second window to draw after the first window further comprises:

setting the style of the second window to transparent.

5. A method comprising:

creating a first window movable with respect to a display which at least partially overlaps a second movable window in a region of overlap on the display, wherein the first movable window further comprises a first non-overlap region, and the second movable window further comprises a second non-overlap region and at least one application element;

configuring the first and second movable windows to move correspondingly to one another;

configuring the first and second movable windows such that the region of overlap is drawn first with a chroma color and then with other colors representing window elements; and

rendering dynamic video content only to areas of the region of overlap which have the chroma color.

6. The method of claim 5 further comprising:

configuring one of the first and second movable windows to receive user interface events.

7. An article comprising:

a memory having stored thereon instructions which, when executed by a processor, result in

creating a first window to display dynamic video content which at least partially overlaps a second window on a region of overlap on the display, wherein the first window further comprises a first non-overlap region, and the second window further comprises a second non-overlap region and at least one application element;

setting the pixels of the first window to a chroma color;

setting background pixels of the second window in the region of overlap to the chroma color; and

configuring the second window to draw the at least one application element after the first window has displayed at least a portion of the dynamic video content.

8. The article of claim 7 in which the instructions, when executed by the processor, further result in:

configuring the first and second windows as children of a common parent window.

9. The article of claim 7 in which the instructions, when executed by the processor, further result in:

configuring the second window to receive user interface events.

10. The article of claim 7 in which the instructions, when executed by the processor to configure the second window to draw after the first window, result in:

setting the style of the second movable window to transparent.

11. An article comprising:

a memory having stored thereon instructions which, when executed by a processor, result in

creating a first window movable relative to a display which at least partially overlaps a second movable window in a region of overlap on the displays wherein the first movable window further comprises a first non-overlap region, and the second movable window further comprises a second non-overlap region and at least one application element;

configuring the first and second movable windows to move correspondingly to one another;

configuring the first and second movable windows such that the region of overlap is drawn first with a chroma color and then with other colors representing window elements; and

rendering dynamic video content only to areas of the region of overlap which have the chroma color.

12. The article of claim 11 in which the instructions, when executed by the processor, further result in:

configuring one of the first and second movable windows to receive user interface events.

13. A system comprising:

a processor;

a memory coupled to the processor by way of a bus, the memory having stored thereon instructions which, when executed by a processor, result in

creating a first window movable relative to a display which at least partially overlaps a second movable window in a region of overlap on the display, wherein the first movable window further comprises a first non-overlap region, and the second movable window further comprises a second non-overlap region and at least one application element;

configuring the first and second movable windows to have a common parent window;

configuring the first and second movable windows such that the region of overlap is drawn first with a chroma color and then with other colors representing window elements; and

rendering dynamic video content only to areas of the region of overlap which have the chroma color.

14. The system of claim 13 in which the instructions, when executed by the processor, further result in:

configuring one of the first and second movable windows to receive user interface events.

15. The system of claim 13 in which the instructions, when executed by the processor to configure the first and second movable windows such that the region of overlap is drawn first with a chroma color and then with other colors representing window elements, result in:

setting the style of one of the first and the second movable window to transparent.
