[Bug 196917] New: Problem with "sticky" tooltips in album view

https://bugs.kde.org/show_bug.cgi?id=196917

           Summary: Problem with "sticky" tooltips in album view
           Product: digikam
           Version: 0.10.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0 (using KDE 4.2.4)
OS:                Linux
Installed from:    Ubuntu Packages

When I am in the album view looking at thumbnails, a tooltip appears
if I hover over an image for a second or so. The tooltip fades in
quite quickly rather than appearing instantly. If, while the tooltip
is fading in, I click on an image to preview it, the tooltip
disappears, the preview image is shown and the tooltip reappears
again in the same position. Until I pass the mouse over the tooltip,
it will not go away.

This keeps happing to me (every minute or two) and is quite
distracting. It took me a while to figure out how to reproduce it
and it is quite hard to get the timing just right when trying to do
it deliberately, but it does seem to be caused by switching views
just as the tooltip is fading in.

The tooltip even stays open when I open the Settings dialog box
(and obscures my view). In that case, I have to close the dialog
box and pass the mouse over the tooltip to get rid of it, as it
will not go away while the dialog is open. I guess that the tooltip
does not register any mouse movements while the modal dialog is
open.

Is there a problem in the code that dismisses the tooltips if
their display is interrupted while they are fading in?

Just noticed that the tooltips sometimes stay open and on top of other
windows when I just Alt-Tab between them, but I cannot make it happen
reliably.

I have noticed this behavior as well, sometimes, not reproducable.
For 1.0beta/current trunk the code has mostly been reimplemented and IIRC I
took inspiration from Qt tooltip code directly, so hopefully well tested code.

I tried to reproduce it, but with current SVN I can't.

I upgraded to 1.0.0-beta5 (Kubuntu 9.10) and, after a few
minutes use, I didn't get any "sticky" tool-tips. Not a very
thorough test, but promising.

Before upgrading to the beta I was spending hours and hours
rating thousands of photos and switching between the thumbnail
view and preview a lot and the unrelenting "sticky" tool-tips
were doing my head in.

I'll be using it heavily over the weekend, so I'll report back
again after that.

Note that Kubuntu unfortunately added a crashy release of digiKam. The crashes
will mostly be triggered in the camera import dialog.
digiKam-beta6 fixes these issues, but I'm not sure if Kubuntu will ever update
the package due to their upgrading policies.
If you don't fear compiling, grab the new beta6 instead for testing.

I've been busy tagging and rating a few thousand more photos
in 1.0.0-beta5 (which I didn't find too buggy). I did not get
a single repeat of the "sticky" tool-tips problem. In the
previous version 0.10.0, I was getting "sticky" tool-tips
ever minute or two.

It looks like the new code has fixed the problem (whatever it
was), so I think you can close this issue.

Thank you.

Spoke too soon...

I'm using 1.0.0-rc1 at present. If I hover over an image in the
thumbnail view, a tool-tip opens. If I then quickly move the mouse
pointer to the album tree, the tool-tip stays open. It even stays
open on top of another widow when I hit Alt+Tab. Moving the mouse
pointer into and out of the tool-tip gets rid of it. I happens every
single time. I've never been able to reproduce it so easily before....

....and now that I have typed in this bug report and tried to
reproduce it again, I can't!....

....and now that I have switched over and back a few times and have
run a metadata update job in the background, it has started again....

....now it has stopped again....

....OK, while a job is running the the background chewing up CPU
time, I hover over an image and the tool-tip fades in. WHILE it is
fading in, if I hover over a second image until its tool-tip appears
and quickly move the mouse to the album tree, the tool-tip sticks.
Now, if I hover over another thumbnail and go quickly to the album
tree, the tool-tip sticks again. It will stick every time from now
on. It seems like digiKam has got itself into a strange state. It
becomes very easy to reproduce until I switch to another window or
until the background job finishes chewing up CPU time.

While something else is running, the tool-tip takes much longer
to fade in (maybe 0.5s instead of 0.1s), so it is easier to start
displaying another tool-tip in that time. That seems to be the
root of the problem: opening one tool-tip while another is fading
in puts digiKam into a state that causes tool-tips to stick quite
regularly (or all the time if you make an effort).

Anyway, this is not "FIXED" yet. I'll let you change the state as
appropriate.

Just to confirm: You mean the thumbnail view (or icon view) and not the
thumbbar that appears when one image is opened for preview?

The thumbnail view (the one where when the main area of the
window is full of image thumbnails with little annotations
around them).

Digikam does not fade the tooltips at all. It just shows and hides. It's a kwin
effect that does this fading. It would be interesting if you can reproduce with
the Fading effect or desktop effect at all switched off.

The code for the tooltip hiding was mostly copied from Qt, it should be pretty
well tested.

Perhaps "mostly copied" and "pretty well tested" have resulted in
"mostly works pretty well".

Once the effect has been triggered the first time, it is not
necessary to catch a tool-tip in "mid-fade" to trigger it again.
There must be some state information somewhere that is causing
this effect under some unanticipated circumstances. Perhaps the
state is toggled without being checked to see if it is sane.

SVN commit 1066042 by mwiesweg:

Dont check for isVisible() here.
I cannot reproduce the problem for the bug report, but after careful reading,
that's one of the few differences I can spot to Qt's QTipLabel.
