Checkbox Widget#
Use a checkbox to turn on/off the visibility of meshes in a scene.
See pyvista.Plotter.add_checkbox_button_widget()
for more details.
import pyvista as pv
Single Checkbox#
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 Checkboxes#
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'],
]

"""Helper callback to keep a reference to the actor being modified."""
