creating a renderer in qt fails for some axes types about vedo HOT 3 CLOSED

Idea:

pass the
vtkWidget (QVTKRenderWindowInteractor) as an argument when creating the Plotter.

vp = Plotter(qtWidget = vtkWidget)

then the plotter can

• override of "offscreen" and "interactive" settings
• set self.interactor

in Plotter.show():

• assign the newly created renderer to the widget
• add the axis :-)

Marco, if you like this then I can implement it and create a merge request for it.

some more information:

The error occurs in addons.py in the function addIcon()
The root cause is that the orientation type widget can not be enabled without a interactor set. (line 637: widget.EnabledOn()
Also, the interactor needs to have a the rendered assigned.

A work-around is to skip the creation of axis on creation and add them manually later.
This needs to be done after adding the renderer to the widget.

        self.iren = self.vtkWidget.GetRenderWindow().GetInteractor()  # create interactor here
        
        vp = Plotter(offscreen=True, interactive=False, axes=0) # <== No axes
        vp += Cone()
        vp.show()  # to create renderer

        # assign the renderer
        self.vtkWidget.GetRenderWindow().AddRenderer(vp.renderer)

        # set interactor and create axes "manually"
        vp.interactor = self.iren
        vp.addAxes(4)

Yup! That is a very nice idea!
