--- Comment #4 from vialav <d...@bk.ru> --- ```python from traits.etsconfig.api import ETSConfig ETSConfig.toolkit = 'wx' ``` #https://stackoverflow.com/questions/52930781/qt-api-environment-variable ```python import os os.environ["QT_API"] = "pyqt5" ``` To manipulate it from under Python(s) without a restart. Setting ETSConfig.toolkit = 'wx' under Python 3 + VTK 8 + Mayavi 4.7.0 (compiled from sources + `apptools` fix) actually does work under IDLE and **not** under Cantor (see below), but not under Python 2 + VTK 6. ```python from traits.etsconfig.api import ETSConfig ETSConfig.toolkit = 'wx' # Create the data. from numpy import pi, sin, cos, mgrid dphi, dtheta = pi/250.0, pi/250.0 [phi,theta] = mgrid[0:pi+dphi*1.5:dphi,0:2*pi+dtheta*1.5:dtheta] m0 = 4; m1 = 3; m2 = 2; m3 = 3; m4 = 6; m5 = 2; m6 = 6; m7 = 4; r = sin(m0*phi)**m1 + cos(m2*phi)**m3 + sin(m4*theta)**m5 + cos(m6*theta)**m7 x = r*sin(phi)*cos(theta) y = r*cos(phi) z = r*sin(phi)*sin(theta) # View it. from mayavi import mlab s = mlab.mesh(x, y, z) mlab.show() ``` /usr/lib/python3/dist-packages/pyface/ui/wx/clipboard.py:25: wxPyDeprecationWarning: Call to deprecated item.
