Bug 491543

Created attachment 172475 [details]
Application menu not aligned to panel edge

SUMMARY

For a horizontal panel, opening a widget at the ends of the panel (e.g. the kickoff application menu, or the digital clock) should align the left/right edge to the panel. Similarly, with a vertical panel, the opened menu/widget should align to the top/bottom edge.

STEPS TO REPRODUCE

1. Edit the default (horizontal) panel and decrease the width slightly  so as to not span the entire width of the desktop. Decrease the height for a vertical panel.
2. Open the application menu by clicking on the application menu icon (or the calendar by clicking on the digital clock) in the panel.

OBSERVED RESULT

The application menu that opens is not aligned with the panel width. See attachment showing the issue. The calendar at the other end of the panel is likewise not aligned to the panel end points.

EXPECTED RESULT

As long as the panel is wide enough, the opened menu/widget should align to the panel end points. If the panel is not wide enough, we could align preferentially to the end of the panel closest to the widget's location in the panel.
