I suspect this is a well known story, so bear with me since my Google search (patience?) did not come up with a definitive answer. Seems like Openscad is using the old Qt4 version instead of Qt5. I would like tu understand if it's feasible to switch to Qt5 or not. My personal concern is that some keyboard shortcuts are broken with non US keyboard layouts, at least under Windows. For example you can't use Ctrl+] and [ for zoomin. Same for the (hopefully) upcoming shortcuts Ctrl+* and Ctrl+Shift+*.

I guess the question is if it's ok to drop Qt4. Officially it's dead since beginning of this year I think. ciao, Torsten.

OpenSCAD uses Qt5 on all platforms, if you have a recent build.

Still the Windows cross compilation brings in Qt4. Or am I wrong? -- View this message in context: http://forum.openscad.org/Qt5-tp17818p17821.html Sent from the OpenSCAD mailing list archive at Nabble.com.

I'm running a Windows developer snapshot from the downloads page, and the library info says Qt5. The last time I looked at the build scripts, they were searching for either Qt5 or Qt4, and using whatever was installed, with a preference for Qt5, but I don't know how the Windows build works. If you are doing your own build, maybe the build script can't find your Qt5 installation?

I just discovered that for the Win building scripts the default is Qt4, but you can specify Qt5. I'll have a try at it later On Tue, Jun 28, 2016 at 4:55 PM, doug.moen [via OpenSCAD] < ml-node+s1091067n17822h57@n5.nabble.com> wrote: > I'm running a Windows developer snapshot from the downloads page, and the > library info says Qt5. > > The last time I looked at the build scripts, they were searching for > either Qt5 or Qt4, and using whatever was installed, with a preference for > Qt5, but I don't know how the Windows build works.

The Windows version I am running claims to be using Qt version: 5.4.1 and it isn't slow on large models.

Same for me, Qt5 reported in Library Info. The comments in the scripts seem unreliable. I'll have to look for a different solution to my problem.

The only issue (as far as I know), that had anything to do with Qt4 vs. Qt5 is about the QGLWidget on Linux. This is fixed quite some time ago by switching to the new QOpenGLWidget provided in Qt5. AFAICS that fix is also backported to the Debian version in release openscad-2015.03-2+dfsg-1. I don't know how other distributions handle things. So there is nothing to fix at this time for any of the 3 supported platforms. There is still a general issue with big models as the OpenGL code is mostly using the old fixed OpenGL pipeline which is slow, does not use GPU accelleration and can cause high CPU load for models with lots of vertices. That's not a "fix" though, but a serious project to get the code updated to use more modern features provided by modrern GPUs/drivers. ciao, Torsten.
