A button is receptive to user clicks and returns an id corresponding to a method, it may have specific arguments too.

Mouse motion is also handled: the button appearance can change according to current focus.

Keyword Arguments:

  • callback (Callable) – the reference to the function that should be call after a click.

  • size (tuple[int, int]) – the size of the button following the format “(width, height)”, defaults to BUTTON_SIZE.

  • title (str) – the text that should be displayed at the center of the element.

  • position (Position) – the position of the element on the screen.

  • background_path (str) – the path to the image corresponding to the sprite of the element.

  • background_hover_path (str) – the path to the image corresponding to the sprite of the element when it has the focus.

  • no_background (bool) – specify whether a background should be present or not, defaults to False.

  • margin (Margin) – a tuple containing the margins of the box, should be in the form “(top_margin, right_margin, bottom_margin, left_margin)”, defaults to (0, 0, 0, 0).

  • disabled (bool) – a boolean indicating if it is not possible to interact with the button, defaults to False.

  • font (pygame.font.Font) – the font that should be used to render the text content.

  • text_color (pygame.Color) – the color of the text content, defautls to WHITE.

  • font_hover (pygame.font.Font) – the font that should be used to render the text content when the mouse is over the button.

  • text_hover_color (pygame.Color) – the color of the text content when the mouse is over the button, defaults to WHITE.

  • complementary_text_lines (str) – the other text lines that should be displayed in addition of the title.
