[chimerax-users] pyqtchart

[Greg Couch]

The easiest solution for you would be for ChimeraX to bundle in the 
compatible version of PyQtChart.  But we can't without releasing 
ChimeraX under the GPL license.   And we're not willing to do that at 
this time.


So the next best thing is for you to give an explicit version in the 
dependency tag.  Right now, ChimeraX is using PyQt5 5.12.3 with Qt 
5.12.8.  So the dependencies should be (untested!):

  ...
<Dependencies>
     <Dependency name="pyqtchart" version="==5.12"/

     <Dependency name="ChimeraX-Core" version="~=1.0rc1"/>

</Dependencies>
...

And after the ChimeraX 1.0 release, change that dependency to "~=1.0.0", 
and you should consider making your bundle generally available on the 
ChimeraX Toolshed.  Later, when ChimeraX 1.1 comes out that uses a 
different version of PyQt, you will need to make a new release of your 
bundle with those dependencies.  That is, your bundle will need to be 
tied to the exact version of ChimeraX.


     HTH,


     Greg
