When a set PV assigned to the QENumericEdit widget, I get always 6 extra leading zeros and 5 precision zero digits despite whatever I set the values of "leadingZeros" and "precision" properties. The PVs that I encountered before I stopped working:

1. HLM and DHLM
2. VAL and DVAL
3. LLM and DLLM
4. RLV
5. TWV
6. OFF
7. VMAX

If I set those PVs to a QELabel, the value is displayed fine and If I set the VAL or DVAL PVs to a QENumericEdit the value is also displayed fine.

Another issue with QENumericEdit is that CTRL+C and CTRL+V does not work but right click > copy work. These shortcuts work on the other widgets.

On building qeframework with Qt6.6.2, it fails below following error -

QEEmitter.cpp:118:30: No matching conversion for functional-style cast from 'QMetaMethodArgument' to 'QGenericArgument'
qobjectdefs.h:82:21: candidate constructor (the implicit copy constructor) not viable: no known conversion from 'QMetaMethodArgument' to 'const QGenericArgument' for 1st argument
qobjectdefs.h:82:21: candidate constructor (the implicit move constructor) not viable: no known conversion from 'QMetaMethodArgument' to 'QGenericArgument' for 1st argument

Hi,

Can I suggest that your README.md file(s) should contain a link to https://qtepics.github.io/index.html which will allow potential users to see your website properly rendered without having to know how to get there from the repo?

BTW I just changed the link on the EPICS Extensions web-pages to point to that githubio page, hope that's OK.

Hi, all:
Recently I started to buit the epicsqt using this set(Windows 7 | MSVC 14.0, 64 bit | EPICS_HOST_ARCH=windows-x64 | EPICS3.14.12.3 | QWT-6.1.3 | QT-5.7.0 |EPICSQT- 3.4.3),I built the qwt sucessfully，the qt-designer can find the qwt widget. I used the qtcreator,qmake,jom.exe to build the qeframework and gui sucessfully and generated a qeplugin.dll and qeplugin.lib,I copied them to some directory just like the qwt,but the qt designer widgets box can not display.I do not konw why. also when buit the qegui, the qegui.exe can not work correctly,always say run out of avutil-56.dll. I do not set QE_FFMPEG at all. Any can help me solve the two problems and tell me how to build the epicsqt (qeframework and qegui) correctly? Thank you!
