Hi Dora,
Hi everyone else,
just to let you know, Andreas fixed the Qt 5 OS X bug the last weekend :-) and
I removed Qt 4 support from MITK today. So if you’re planning to use the next
MITK release I would recommend not to put too much effort into Qt 4 related
bugs anymore.
Best,
Stefan

Hi Dora,
unfortunately the OS X Qt 5 bug seems to be one of the top 5 most difficult
bugs to track down in the whole history of mankind… and dinosaurs. :-) / :-(
Every time someone thinks she or he has found a hot scent on what is causing
the problem, it’s a red herring. It’s just ridiculous. We planned to remove Qt
4 support the last release and this was the only blocker for actually doing
this. We postponed the Qt 4 removal for the upcoming release and unfortunately,
it seems like we won’t make it again. Believe us, if we could fix this bug by
sacrificing cute little bunnies, we would do it! – No kittens though… kittens
are sacrosanct.
That’s why we set DESIRED_QT_VERSION to 4 by default on OS X. We have a bug
branch for the upcoming release that will introduce a configure error when
setting this cache variable to 5 on OS X in case we won’t make it again. We
also have a – pretty old – bug branch for Qt 4 removal. So we’re prepared for
both denouements.
Anyways, your QtWidgets based GUI shouldn’t look different on Qt 4 / 5. Try to
fix it with Qt 4 and then look at it again with Qt 5, there shouldn’t be any
difference at runtime. All differences we experienced were incompatibilities in
the Qt API which result in compiler errors (in this case fix by checking
QT_VERSION and handle both cases).
The vanishing of the department logo is strange, though, as it doesn’t have
anything to do with Qt… as far as I know. I guess it’s a VTK overlay. Last year
we fixed code related to the department logo, maybe you are comparing two
different versions of MITK?
Best regards,
Stefan

Hi everyone,
I was wondering if anybody had any experience of what I described in my last
message. Would really appreciate any thoughts/help on this, please.
Many thanks.

Dear all,
I have an MITK application with custom plugins that I developed and built
originally on Linux but now I need to rebuild it on an iMac machine. First of
all, I realised that to build MITK on Mac, Qt 5 is not suitable as I tried and
it seemed to have problems with mouse interactions within the workbench views
(none of the buttons in the views were responding to the mouse clicks). I had
to therefore downgrade to Qt 4 which looks to be working OK with the MITK
application. This problem with Qt versions is not very clear on MITK build
documentations, as I think the documentation online suggests to use Qt 5 for
all platforms.
My problem with the version built on iMac is now mostly the looks of the GUI.
The buttons in my custom view are all squashed together. It is still usable but
not very user friendly. Also, the department logo is not displaying in the
bottom corner any more. I was wondering if anyone has any experience similar to
these issues. Are these due to the older version of Qt that I had to use?
Many thanks in advance.
Dora
