Hello gentlemen,

I have two monitors with the following parameters.

OS version: Win 11 22H2 (Win 10 has the same problem)

First display: (DELL P2419H)
Display resolution: 1920*1080
Zoom factor: 100%

Second monitor: (DELL D2421DS)
Display resolution: 2560*1440
Zoom factor: 125%

Both monitors are Dell's, but there are some differences in hardware parameters.

Next, I went to run the official Demo ‘MDIExample’.

When I create a new window on the main monitor, there is no problem.

However, when I create a new window on the secondary display, there will be a misalignment of the OpenGL display area, which will even affect the use of other controls.

I encountered this headache when actually using Quarter, which is reflected in my software as follows, and Windows cannot be adapted。

This causes the following concurrency issues:
For example, if I create a cube with 100 sides and click on the point (100, 100, 100), it is possible to end up giving me feedback to the point of (100, 100, 80) in a certain perspective.

My preliminary research found that this problem has nothing to do with the location of the main window, but with the location of the mouse. When creating a new QuarterWidget, the mouse is on the main monitor, and the created QuarterWidget has no problem. But when the mouse is on a secondary monitor, the QuarterWidget created will be misaligned. My current solution is to use code to temporarily move the mouse to the main monitor when creating the QuarterWidget, and then move the mouse to the original location when the creation is complete.

Could have solved my problem temporarily, but it felt a bit funny. I would like to ask if there is a better way to solve this problem. What about making Quarter more compatible with multiple monitors?

Original report by Anonymous.

On a Coin/Quarter application I'm building I have noticed that if I leave the application running for a long time, it becomes unstable and the viewer becomes unresponsive. In fact, the viewer doesn't seem to update, say rotation events, until a menu item on the Qt window becomes active. It is almost like the underlying widget just isn't getting time to update.
I will add that the application has an additional thread that connects to a database.

Any ideas on what I'm doing wrong?

Thanks,

Do you plan to release a version of quarter 1.2 so that it can be compiled with qt6?

I got the following error when running a basic minimal.cpp.

Could anyone know something about how to fix it? Thanks very much.

Hi,

   I hav build the libraries nof quarter and coin3d and now i am trying to run the quarter application, But i am getting this run time error, please help me.

I'm trying to get Quarter to compile under macOS 10.15.7 (after running into X11 library issues with SoXt).

I have Coin3d installed via Homebrew, apparently version 4.0.0_1. I first tried automake configure, but that failed, then cmake. Cmake gets further, but I get a ton of Qt related compilation errors (see below) which appear to be due to the use of recent c++ language features. I tried setting the CXX_STANDARD in the CMakeLists.txt file and also setting the c++ standard also in Qmake .pro files but neither had any effect.

Any guidance would be much appreciated. Thanks!

Original report by Nikolay Fedorov (Bitbucket: Unril, GitHub: Unril).

It happens when link against Qt built with default configuration. All OK when Qt is built with "-opengl dynamic -no-angle" options. I think that it should be noted somewhere in readme or install files.

I detect this for Quarter plugin when updating package and trying switch to Qt6 from Qt5 on Windows.
Currently we still use Qt5.

We encountered an issue with building the QtHelp documentation, if the Qt related binaries are not available in PATH[1]:

-- Found Doxygen: /usr/bin/doxygen (found version "1.9.3") found components: doxygen missing components: dot
CMake Error at CMakeLists.txt:213 (message):
  Missing program Qt qhelpgenerator


-- Configuring incomplete, errors occurred!

As a patch[2], I'm using qmake to get the location of Qt binaries and successfully configure the package.

WDYT?

I suspect the problem be the commit 30d08ea in the QuarterWidgetP::removeFromCacheContext() method implementing a workaround for a Coin issue fixed in svn r12818 (probably the hg commit caacaf7).

In detail the call to cc_glglue_instance() added by the workaround fails because the dictionary - under some circumstances - has been already flushed.

Removing the Quarter workaround 30d08ea seems to solve but there are a number of things that are stopping me from proposing a PR:

1. the regression is really old and the example is really ‘basic’: strange that nobody noticed before
2. the comment inside the workaround is referring to a subversion release number that has been lost during mercurial import, so concretely I cannot be sure that svn r12818 is the hg caacaf7
3. the Coin fix caacaf7 (22/01/2009) is older then Quarter workaround 30d08ea (25/01/2009): why writing 30d08ea if already fixed in caacaf7?

As a final consideration, the same code implemented in the ‘legacy’ So[Qt,Xt] libs doesn’t crash.

Regards

Giampiero

Hi,

Compiling Coin and Quarter from the latest branches fails for me, with a message about the coin-config program.

I am able to compile and install coin using cmake. However when I try to ./configure quarter, I got a message that coin-config is not available. After copying it to /usr/local/bin, I get this message:

Any tips?

QOpenGLWidget introduce since Qt 5.4.

Is there no Qt5 support? Or is the README just outdated?

Hi!

I’m trying to compile quarter for ubuntu 16.04, so this is what I did:

1. Installed qt and all the needed dependencies (might happen to be some extra deps probably):

apt install qt4-default qt4-dev-tools libqt4-designer

‌

2. Installed Coin3D and dependencies:

apt install libcoin80-dev

‌

3. Downloaded Quarter, unzipped:

./configure

Quarter configuration settings:
Qt version: 4.8.7
Coin version: 4.0.0a
Quarter version: 1.0.1a
Quarter installation prefix: /usr/local
Qt Designer plugin path: /usr/lib/x86_64-linux-gnu/qt4/plugins/designer

Now, run 'make' and 'make install' to install Quarter

‌

‌

make:

‌

I get it’s some error when it tries to compile the plugins, but I’m lost here.

‌

Hoping you guys can help me find the way to finish compiling it.

thanks!
