Summary: Dragging widget over iframe cause mouse event to hang
Key: CHUKWA-738
URL: https://issues.apache.org/jira/browse/CHUKWA-738
Project: Chukwa
Issue Type: Improvement
Components: User Interface
Affects Versions: 0.5.0, 0.4.0, 0.3.0, 0.6.0, 0.7.0
Reporter: Eric Yang
Both Webkit and Firefox based browser are honoring mouse events inside iframe.
However, if a widget is in a dragging event, and mouse cursor pass through
another iframe. Mouse event get captured by the background iframe and cause
the dragging widget to stall. One trick was to overlay an invisible DIV with
higher zIndex to prevent the background iframe from capturing mouse dragging
event of the transitioning widget. This was implemented several years back for
firefox only, but it looks like the same trick needs to apply to all modern day
browser. This JIRA is to remove the firefox specific check and always overlay
the invisible iframe when mouse is dragging over another iframe.
