从 mayavi 场景中删除工具栏

Question

Is it possible to remove/hide the standard toolbar which is created by default when you plot something with mayavi? I found this: How to remove Mayavi toolbar in python using code

But I don't understand where I should insert this code. Is there something easier like mlab.toolbar.setVisible(False)?

        self.setupUi(self)
        self.splitter.setSizes([100, 300])
        self.splitter_2.setSizes([400, 100])

        container = QWidget()
        mayavi_widget = MayaviQWidget(container)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    action = Action()
    action.show()
    sys.exit(app.exec_())

On a figure, this can easily be done like so:

fig = mlab.figure(1)
fig.scene.scene_editor._tool_bar.setVisible(False)
