50562 - Non-opaque menus don't highlight on mouseover

Status: RESOLVED INCOMPLETE

(Core :: XUL, defect, P3)

Description

[Millennium]

From Bugzilla Helper:
User-Agent: Mozilla/4.75 [en] (Win95; U)
BuildID:    2000082808

If a user has set the menus to be transparent, the menu items do not highlight 
as the mouse passes over them. Note that the menus still *work* just fine; they 
just don't highlight properly (which is potentially a usability issue).

Reproducible: Always
Steps to Reproduce:
1) Add the following to your user.css:

<code>menupopup { opacity: <i>x </i>!important; }</code>
where <i>x </i>is any value between 0 and 1 (I suggest 0.9, but any value 
works).

2) Start Mozilla and use any menu.

Actual Results:  The menu functions, but items do not highlight when the mouse 
is passed over them.							

Expected Results:  Menu items highlight when the mouse passes over them.

CCing Hixie, said to be "the man" in #mozilla. I've tried adding the snippet 
below to both userchrome.css and usercontent.css, in profiledir/chrome/ but it 
doesn't change anything.

are you still seeing this with new builds? we need a testcase

This bug sat here too long, it's a bit obsolete now.  To reproduce, create a file 
at profiledir/chrome/userchrome.css and put this line it:

     menupopup { -moz-opacity: 0.5 !important; }

I'm seeing 2 problems (using recent commercial and mozilla builds on the Mac).
- The first bug is very similar to what is described by the reporter.  If you use 
a menu at the bottom of a browser window ("Business/Tech/Fun/Interact" in 
commercial builds, or just "Mozilla" in public builds), the menu items are not 
highlighted correctly.  The selection is jerky, it stays on just a fraction of a 
second, and it doesn't highlight the text itself but just the margins on both 
sides of the menu item.
- The second bug can be seen in the popup menus of the Preferences dialog. Go to 
the Font panel and click the Font popup.  If you have plenty of fonts and the 
dropdown list doesn't fit in the monitor, you will see the entries displayed 
twice with a small offset offset (I guess because the list was drawn in 2 
passes).  Then is you move the mouse over the items, the highlight leaves some 
traces.  I'm going to attach a screen snapshot.

Reassigned to XP Toolkit / Widgets.

Note that in the snapshot I attached, the problems only appear at the bottom of 
the dropdown list (double display + traces of hilited items).

wow, i love this screenshot ! translucent menus is a completely useless feature 
but i love it, it's fun. i'm voting for it :-)

ps: Win 2K and Mac OS X have some similar feature, btw...

Umm translusency doesn't seem to work anymore?
Was it just too complicated, or did it regress without anyone noticing?

Comment 9

[Andreas Kunz]

Highlighting does work now on Win2k. Anybody on other (Win)OSes like 95 to test?

Translucency does not fully work anymore. The menu fades, but there is no
background visible through them.
I also tried making other elements (like menuitems) translucent, but this
crashed moz.

Windows 95, eh?

Is this worth trying to reproduce?

Too old to be relevant.
