Hi! Thanks for the reply!
I don't use qt designer actually, but I guess i can simply translate this
part of the xml into code:
<customwidgets>
<customwidget>
<class>GLViewWidget</class>
<extends>QOpenGLWidget</extends>
<header>pyqtgraph.opengl</header>
</customwidget>
</customwidgets>
Do you think something like this would work?
class GLViewWidget(QOpenGLWidget):
def __init__(*args, **kwargs):
super(GLViewWidget, self).__init__(*args, **kwargs)
Maybe I am not translating <header>pyqtgraph.opengl</header> , right?
Thanks for the help!
