Checkbox WidgetΒΆ
Use a checkbox to turn on/off the visibility of meshes in a scene.
See pyvista.WidgetHelper.add_checkbox_button_widget()
for more details.
# sphinx_gallery_thumbnail_number = 2
import pyvista as pv
Single CheckboxΒΆ
mesh = pv.Sphere()
p = pv.Plotter()
actor = p.add_mesh(mesh)
def toggle_vis(flag):
actor.SetVisibility(flag)
p.add_checkbox_button_widget(toggle_vis, value=True)
p.show()

Multiple CheckboxesΒΆ
In this example, we will add many meshes to a scene with unique colors and create corresponding checkboxes for those meshes of the same color to toggle their visibility in the scene.
colors = [["ff0000", "28e5da", "0000ff"],
["ffff00", "c8bebe", "f79292"],
["fffff0", "f18c1d", "23dcaa"],
["d785ec", "9d5b13", "e4e0b1"],
["894509", "af45f5", "fff000"]]
class SetVisibilityCallback:
"""Helper callback to keep a reference to the actor being modified."""

self.actor = actor
def __call__(self, state):
self.actor.SetVisibility(state)
