[Interest] QTreeView expand icon changes unexpectedly Qt5.6.0 & VS2015

[Ben Swerts]

Indeed, that’s the issue. I rechecked and it is not related to the version of the compiler.

Thanks for the link to the bug report! That saved us quite some time in tracking down the problem.

Are you sure it is not https://bugreports.qt.io/browse/QTBUG-52230 ?

Hi Anton,

I noticed the same issue with VS2015 Update 2 and Qt 5.6.0 (commercial).
Your post made me realize this seems to be related to the combination of
these two tools.
Our application is built with VS2013 Update 5 while I'm preparing everything
for an upgrade to VS2015. I'm quite certain this issue is not present when
compiling with VS2013.

So if no one has logged a bug for this yet, I would advise you to log one.

Regards,


        Ben

Hi,

I installed the following qt version on my Windows 7 (64bit):

http://download.qt.io/official_releases/qt/5.6/5.6.0/qt-opensource-windows-x <http://download.qt.io/official_releases/qt/5.6/5.6.0/qt-opensource-windows-x86-msvc2015_64-5.6.0.exe> 
86-msvc2015_64-5.6.0.exe

I use Visual Studio 2015 update 2.


I create a Qt Widget application with q QTreeView and some QComboBox'es.

In my treeview I see the expand iccons:

- they look like a triangle lile '>' when the treenode
  is *not* expanded

- they look like a triangle lile 'V' when the treenode
  is not *expanded*

Now I click here and there in my application, clicl on a QComboBox and now
some strange magic happens.

1. The expand icons change to a '[+]': a plus in a rectangle
   like you know it from the windows explorer.

2. As soon as the mouse pointer hoovers over the
   expand icon it becomes *insisible*.

In the Qt Designer in Qt Creator, I see the same problem, the expand icons
(in the property pane) look like a '[+]' like in the windows explorer, but
they becone invisible as soon as the mouse pointer is over the expand icon.


My questions:

- do you observe the same things?
- did I forget to initialize something?
  (don't think so because the Qt Designer has the same problem)
- or is it a bug which will be fixed in 5.6.1 or 5.7.0 ?


Thanks for a hint

  Anton
