Abstract: A technique for handling user-interface gestures in non-rectangular regions of a graphical user interface includes creating a class comprising an event handler for an onmouseover event and an event handler for an onmouseout event. The technique further includes adding each of a group of graphical elements to the class. Adding a graphical element to the class includes adding a reference to the graphical element to the class and attaching the event handlers to the graphical element. The technique then identifies a specific graphical element in the group that triggered an invocation of one of the event handlers. The technique then determines the closest border of the specific graphical element to the mouse pointer. In the event another graphical element in the group shares the closest border, the technique stops either the onmouseover or onmouseout event from propagating.

Abstract: An illustrative embodiment of a computer-implemented process for detecting code breakage using source code change history receives a point in time within an identified range of time to form a selected time, receives a set of source files associated with the a selected time, receives a set of history files associated with the received set of source files and initializes a workspace in a sandbox using the set of source files and the set of history files. The computer-implemented process incrementally executes the received set of source files from the selected time forward, determines whether a code break occurs and responsive to a determination that the code break occurs, presents a list of files. The computer-implemented process receives an identified file from the list of files to form a suspect file, and receives a correction for the suspect file.
