ComboBox

This example shows how to use the Combobox UI. We will demonstrate how to create ComboBoxes for selecting colors for a label.

First, some imports.

from fury import ui, window
from fury.data import fetch_viz_icons

First we need to fetch some icons that are included in FURY.

fetch_viz_icons()

Out:

Data size is approximately 12KB
Dataset is already in place. If you want to fetch it again please first remove the folder /Users/koudoro/.fury/icons

First, we create a label.

label = ui.TextBlock2D(
    position=(200, 300), font_size=40, color=(1, 0.5, 0),
    justification="center", vertical_justification="top",
    text="FURY rocks!!!"
)

Now we create a dictionary to store colors as its key and their RGB values as its value.

colors = {
    "Violet": (0.6, 0, 0.8),
    "Indigo": (0.3, 0, 0.5),
    "Blue": (0, 0, 1),
    "Green": (0, 1, 0),
    "Yellow": (1, 1, 0),
    "Orange": (1, 0.5, 0),
    "Red": (1, 0, 0)
}

ComboBox

Now we create a ComboBox UI component for selecting colors.

color_combobox = ui.ComboBox2D(items=list(colors.keys()),
                               placeholder="Choose Text Color",
                               position=(75, 50), size=(250, 150))

Callbacks

Now we create a callback for setting the chosen color.

def change_color(combobox):
    label.color = colors[combobox.selected_text]


# `on_change` callback is set to `change_color` method so that
# it's called whenever a different option is selected.
color_combobox.on_change = change_color

Show Manager

Now we add label and combobox to the scene.

current_size = (400, 400)
showm = window.ShowManager(size=current_size, title="ComboBox UI Example")
showm.scene.add(label, color_combobox)

# To interact with the UI, set interactive = True
interactive = False

if interactive:
    showm.start()

window.record(showm.scene, out_path="combobox_ui.png", size=(400, 400))
