QT library version for PVSS 3.9

[bhavna]

Is there any online document for EWO? Which version of QT library does PVSS 3.9 support?

[leoknipp]

Hello,

at the online help you'll find information concerning the implementation of an EWO at the chapter Graphics Editor --> Complex graphic objects --> EWO (External Widget Object).

The version 3.9 is using QT 4, the QTCore4.dll has the version number 4.7.0.0.

Hello,

Thanks for the reply. After making an EWO dll using templateEWO, then qmake and then building it in VS2008, when it was embedded in a panel the logviewer reports error " EWO version used is 1, version 3 should be used".

Best Rgds,
Bhavna

This message is also shown, when the EWO dll is missing a dependency. You should check this first with dependency walker. You could be missing the vc2008 redistributable package.

It could be also that you are running an older 3.9 version, which uses Qt 4.5.3.

By 'older' should i assume PVSS 3.9 without SP1?

[Gertjan van Schijndel]

By older I mean older then 3.9.0 + P084. With patch 84 the Qt version has changed.

[bhavna]

I could not find patch P084 for 3.9. What is the difference between PVSS 3.9 and PVSS 3.9 +SP1 ?
I can see patch P112 for 3.9 is available on this portal. Will it work for QT libray 4.7.0?

[Gertjan van Schijndel]

P112 should work with Qt 4.7.0.
The main difference between 3.9 and 3.9+SP1 is the support. Only 3.9+SP1 is supported.

[ragrawal]

Whether adding patches to any version ( say 3.9) makes it ( say 3.9) + SP1 ?

Also Whether 3.9 + Pxx is latest or PVSS 3.9 + SP1 ?

Or both are not related?

Hi,

please dont mix up patches for different Versions.

In general every SP is treated as a distinct stand alone version.

--> PVSS 3.9 (without SP) is a completely different version than PVSS 3.9.1 (with SP1)

The patches for the SP1 version are on a seperate download page (and the numbering is again starting over with number 001...)

As Gertjan already mentioned PVSS 3.9 is not supported any more therefore we strongly recommend to use the 3.9.1 version (with all the latest patches available).

When you upgrade from 3.9 to 3.9.1 please do a complete uninstall of 3.9 and install 3.9.1 after that (the SP is not a patch but a complete version setup).
(btw. your projects dont need to be upgraded)


best regards
