Error finding a member function in QOpenGLWidget

[viniltc]

Hi All,

I trying to build a program to display Quaternion rotation. I have an QOpenGLWidget. There is a class glwidget.cpp which I included in the project. There is a member function called updateOrientation().

I do this in order to update orientation of a 3d object using Quaternion.

  ui->glWidget->updateOrientation(quat[0],quat[1],quat[2],quat[3]);

but I get an error:

settings.cpp:223:18: error: no member named 'updateOrientation' in 'QOpenGLWidget'

I dont know why this is happening , I included the class glwidget.cpp , also I make sure opengl is included in the .pro file as well.

What might be the issue here?

Thanks a lot

Hi
so glWidget is a QOpenGLWidget child that lives in glwidget.cpp
and you added a new method for it and it can't see it ?

can you show glwidget.h ?

Im not sure are using the custom widget on as the error is
'updateOrientation' in 'QOpenGLWidget' << but if you have a subclass then it
should say some other name in my book.

So i think you have a plain QOpenGLWidget in your form and
you really wanted some custom one ?

Like forgetting to promote it to the one in glwidget.cpp
So its just the Qt build in and dont have this function as that is added to the derived class/custom class.

@mrjj Thanks a lot.! It got solved. It was problem due to I forgot to promote it to the glwidget.cpp.
