Dan Stimits commented on OFBIZ-9270:
------------------------------------
A small observation to note is that visually a 1-pixel padding between the navigation summary and the pop-up menus will not matter...it's the bounding box which is used in determining a mouse exit event which causes the pop-up to actually disappear.
If you look at BLUELIGHT it also has a *visual* 1-pixel padding between the hot spot area and the pop-up, but the pop-up never disappears on moving the mouse at any slower or faster speed from one area to the other...I conclude that the bounding box for mouse events is set separately from the graphics, and that the bounding box in BLUELIGHT is at least 1-pixel larger than visual graphics (overlapping that 1-pixel gap), whereas in TOMAHAWK the bounding box for mouse events is following the same box as the visual graphics where the 1-pixel gap results in a mouse exit event from the hot spot. The question becomes "how is the hot spot bounding box determined and why is it 1-pixel different between TOMAHAWK and BLUELIGHT"?
> Mouse/Navigation Fails: Context-Sensitive Menu Can't Be Reached

> Key: OFBIZ-9270
> URL:
https://issues.apache.org/jira/browse/OFBIZ-9270> Project: OFBiz
> Issue Type: Bug
> Components: ALL COMPONENTS
> Affects Versions: Trunk, 16.11.01
> Environment: Fedora Linux, gradlew used on 16.11.01 with demo data, Firefox and Konqueror browsers.
> Reporter: Dan Stimits
> Priority: Minor
>
> There is a navigation summary set of icons in the upper left web page corner just below the Ofbiz logo. In my example, under
https://localhost:8443/catalog/control/main, the navigation summary is "Applications > Catalog Manager".
> Using this example URL, hovering the mouse over "Applications" or over "Catalog Manager" (a mouse enter event) triggers a context-sensitive sub-menu below those navigation points. Moving the mouse down should reach those sub-menus, but a 1 pixel padding between drop-down menu produces a mouse exit event which in turn triggers removing the context menu before the mouse can reach it.
> This is a major issue because navigation of menus by mouse is required and there is no other workaround (such as hot keys) satisfactory for practical use of Ofbiz. This issue appears to have an effect on all URLs with a summary navigation bar in the upper left.
> This issue occurs under multiple web browsers. Base testing is with Firefox and Konqueror under Linux/KDE.
