Creating custom EWO for the Area Chart.

[tabrez24m]

Hello,

I am trying to create custom EWO for Area chart.
I have created/build the ewo file using "EWO Basics and Development".
When I am adding this into the Gedi panel it is throwing error -
"WCCOAui1:VarAttrElem "pixmap" isAttribute(): type not implemented:QVARIANT_VAR"

How to resolve this error.......
What are the steps to create custom EWO for charts other than pushButton to be followed in Qt project.
Because the example EWO project is given for two pushButtons (under "EWO Basics and Development" steps), that I am able to add in the Gedi panel.
I am using WinCC OA 3.18 P018

First try to resolve the 'Could not load shared library' error, which has already come up multiple times on this forum with EWOs/CtrlExtensions.

Have a look at these topics:
Problem in EWO widget
EWO and shared library
Library Include Problem on EWO
How to build an EWO?
