Missing Qt libraries for TInspector


I installed the 7.2 beta and wanted to test the QT browser. On Installation I selected binaries (no source, no documentation, no samples) and TInspector. After installing everythign works as normal (draw.exe etc work well) but running the dfbrowser.bat reports an error due to missing QT libraries.

Looking in the root folder with all listed libraries (ffmpeg, vtk etc.) there is no QT folder. I suppose Qt was not installed correctly.

Have you any advise how to fix this?

Re: Missing Qt libraries for TInspector

I think it is an issue with missing dependencies within installer for new item TInspector. Try re-installing with (Qt) samples checked.

7.2.0 feedback

(As there is no thread for the 7.2.0 public release let me use this one for the Beta).

Congratulations on the 7.2.0 release !

Our team did not have enough time to port to 7.2.0 Beta given three weeks window and own existing assignments. Although we tried to regularly catch up with git we consistently failed due to significant porting efforts so we gave up and currently try to use Beta/public releases. Hence the feedback comes late.

A couple of issues so far:

The porting is not over yet, so perhaps more feedback will be provided.
Hope the above will be helpful anyway.
Best regards,

Re: 7.2.0 feedback

Thanks for a feedback!

The issue reported as #0029115 is not a bug but intended modification described in Upgrade Guide:

Change in Geom(2d)Adaptor_Curve::IsPeriodic

Since 7.2.0 version, method IsPeriodic() returns the corresponding status of periodicity of the basis curve regardless of closure status of the adaptor curve (see method IsClosed()). Method IsClosed() for adaptor can return false even on periodic curve, in the case if its parametric range is not full period, e.g. for adaptor on circle in range [0, π]. In previous versions, IsPeriodic() always returned false if IsClosed() returned false.
