========
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.


.. code-block:: default

    from fury import ui, window







First, we create a label.


.. code-block:: default


    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.


.. code-block:: default


    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.


.. code-block:: default


    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.


.. code-block:: default



    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.


.. code-block:: default


    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))
