Supporting user interactions with rendered graphical objects

摘要

A graphical object is rendered to a pixel buffer, such that a software application executing on a computing device displays the contents of the pixel buffer via a user interface. An invisible element is created and positioned under the cursor in response to detecting that the cursor is positioned over the feature being displayed via the user interface. The software application automatically repositions the invisible element in accordance with a movement of the cursor. A change in the position of the invisible element is determined, and the graphical object is repositioned within the pixel buffer in accordance with the change in the position of the invisible element.

主权项

1. A tangible non-transitory computer-readable medium storing thereon a set of instructions that, when executed on one or more processors in a computing device having a user interface, cause the one or more processors to:
cause a web browser executing on the computing device to render a web page that includes a pixel buffer in a static position relative to the web page; render a graphical object to the pixel buffer, wherein the web browser displays the web page and the contents of the pixel buffer via the user interface; in response to detecting that a cursor is positioned over the graphical object displayed via the user interface, cause the web browser to create an invisible element positioned under the cursor, wherein the web browser automatically repositions the invisible element in accordance with a movement of the cursor; determine a change in the position of the invisible element; reposition the graphical object within the pixel buffer in accordance with the change in the position of the invisible element as the position of the invisible element changes, while the pixel buffer remains in a static position relative to the web page; and remove the invisible element when the cursor is no longer positioned over the graphical object.
