ListBoxΒΆ

This example shows how to use the UI API. We will create a list some geometric shapes from DIPY UI elements.

First, a bunch of imports.

from fury import ui, window

Create some text blocks that will be showm when list elements will be selected

welcome_text = ui.TextBlock2D(text="Welcome", font_size=30,
                              position=(500, 400))
bye_text = ui.TextBlock2D(text="Bye", font_size=30, position=(500, 400))
fury_text = ui.TextBlock2D(text="Fury", font_size=30, position=(500, 400))

example = [welcome_text, bye_text, fury_text]

Hide these text blocks for now

def hide_all_examples():
    for element in example:
        element.set_visibility(False)


hide_all_examples()

Create ListBox with the values as parameter.

values = ["Welcome", "Bye", "Fury"]
listbox = ui.ListBox2D(
    values=values, position=(10, 300), size=(200, 200), multiselection=False
)

Function to show selected element.

def display_element():
    hide_all_examples()
    element = example[values.index(listbox.selected[0])]
    element.set_visibility(True)


listbox.on_change = display_element

Now that all the elements have been initialised, we add them to the show manager.

current_size = (800, 800)
show_manager = window.ShowManager(size=current_size,
                                  title="DIPY UI ListBox_Example")

show_manager.scene.add(listbox)
show_manager.scene.add(welcome_text)
show_manager.scene.add(bye_text)
show_manager.scene.add(fury_text)
interactive = False

if interactive:
    show_manager.start()

window.record(show_manager.scene,
              size=current_size, out_path="viz_listbox.png")
