Omni::UI#

Omni::UI is Omniverse’s UI toolkit for creating beautiful and flexible graphical user interfaces in the Kit extensions. Omni::UI provides the basic types necessary to create rich extensions with a fluid and dynamic user interface in Omniverse Kit. It gives a layout system and includes widgets for creating visual components, receiving user input, and creating data models. It allows user interface components to be built around their behavior and enables a declarative flavor of describing the layout of the application. Omni::UI gives a very flexible styling system that allows deep customizing the final look of the application.

Typical Example#

Typical example to create a window with two buttons:

import omni.ui as ui

_window_example = ui.Window("Example Window", width=300, height=300)

with _window_example.frame:
    with ui.VStack():
        ui.Button("click me")

        def move_me(window):
            window.setPosition(200, 200)

        def size_me(window):
            window.width = 300
            window.height = 300

        ui.Button("Move to (200,200)", clicked_fn=lambda w=self._window_example: move_me(w))
        ui.Button("Set size (300,300)", clicked_fn=lambda w=self._window_example: size_me(w))
