Abstract

A content display system is described herein that combines the positive attributes of brushes and web content by allowing web content to be applied as a brush. The content display system renders web content and creates a bitmap of the rendered web content. The bitmap of the web content as rendered by a web host is captured and used as the pixels for a web brush. The brush can be used wherever other types of brushes can be used. In some embodiments, the brush content is refreshed under control of the application. Web content provided through a brush is much more versatile than simply compositing rendered HTML with other visuals. Thus, the content display system allows applications to display web content inside an application sandbox or other platform using the familiar form to application developers of a brush.

Claims

1. A computer-implemented method for exposing web content through a user interface brush, the method comprising:

receiving a request to create a web brush that displays web content, wherein web content is a web page available from the internet and wherein the web brush is a programmatic data type that can used by application program code to paint the content of the brush on a rendered surface;

identifying web content to be displayed by the web brush;

rendering the web content to prepare the content for display;

capturing a snapshot of the rendered web content;

receiving a request from a user interface element that paints with a brush for the captured snapshot of the rendered web content; and

providing the captured snapshot of the rendered web content in response to the brush request,

wherein the preceding steps are performed by at least one processor.

2. The method of claim 1 wherein receiving the request to create the web brush comprises receiving a programmatic request to create a web brush object, and creating the web brush object in response.

3. The method of claim 1 wherein identifying web content comprises receiving a Uniform Resource Locator (URL) that identifies a source of web content.

4. The method of claim 1 wherein rendering the web content comprises invoking a web browser control to retrieve the identified web content, parse Hypertext Markup Language (HTML) that defines the web content, and display the content according to a layout specified by the HTML.

5. The method of claim 1 wherein rendering the web content comprises downloading any images or other content associated with the web content and displaying those items.

6. The method of claim 1 wherein rendering the web content comprises rendering the web content to a hidden window, wherein a user does not have direct access to the content other than through the user interface element using the web brush.

7. The method of claim 1 wherein rendering the web content comprises receiving a size that defines a region for which to render the web content.

8. The method of claim 1 wherein capturing the snapshot comprises requesting that a web browser control that rendered the content provide a bitmap of the content.

9. The method of claim 1 wherein capturing the snapshot comprises invoking an operating system print facility to capture an appearance of the web content.

10. The method of claim 1 wherein capturing the snapshot comprises storing the captured snapshot for later use in response to brush requests.

11. The method of claim 1 wherein receiving the request comprises invoking an interface of a web brush object that represents the web brush to request a bitmap that provides a pattern of the brush.

12. The method of claim 1 wherein the user interface element paints at least some of a displayed area with the captured snapshot of the rendered web content.

13. A computer system for displaying web content using a graphical user interface brush, the system comprising:

a processor and memory configured to execute software instructions;

an application interface component configured to provide an interface to one or more software applications to interact with the system;

a content rendering component configured to render web content for display, wherein web content is a page available from the internet;

a content capture component configured to capture a snapshot of the rendered web content to use as content of a web brush, wherein the web brush is a programmatic data type that can used by application program code to paint the content of the brush on a rendered surface; and

a brush interface component configured to provide an interface to one or more user interface elements that use brushes to paint one or more attributes of the user interface elements.

14. The system of claim 13 wherein the application interface component is further configured to provide application programming interfaces (APIs) for creating a web browser control, creating a web brush control, setting a source location from which to retrieve web content, associating the web browser control with the web browser brush control, associating a web browser brush with one or more user interface elements, and updating content displayed by the web browser brush control.

15. The system of claim 13 wherein the content rendering component is further configured to receive size information through the application interface component and render content based on the received size information.

16. The system of claim 13 wherein the content capture component is further configured to interface with operating system provided capabilities for capturing bitmap content to capture the snapshot.

17. The system of claim 13 further comprising a content update component configured to handle one or more requests to update rendered web content associated with the brush.

18. The system of claim 17 wherein, upon receiving a request to update web content, the content update component invokes the content rendering component to produce an updated rendering of the web content, and the content capture component to capture a new snapshot of the rendered web content.

19. A computer-readable storage medium comprising instructions for controlling a computer system to update web content provided by a brush, wherein the instructions, upon execution, cause a processor to perform actions comprising:

receiving a request to update web content associated with a web brush that paints the web content onto a region of a user interface element, wherein web content is a web page available from the internet and wherein the web brush is a programmatic data type that can used by application program code to paint the content of the brush on a rendered surface;

requesting updated web content from a source of the content;

rendering received updated web content;

capturing an updated snapshot of the rendered web content; and

setting the web brush content to the captured updated snapshot, so that the user interface element that paints with the web brush will display the updated snapshot of the web content.

20. The medium of claim 19 wherein receiving a request to update web content comprises detecting that an application invoked an application programming interface (API) for redrawing the content of the web brush.
