def add(block : Layout::Block) #

Adds a component to the hierarchy


[View source]
def build #

Loads all of the constraints from every component in this hierarchy into the solver. This should only be ran once.

def height=(size) #

Changes the height of the display

def on_input(event : InputEvent) #
Description copied from class GUI::Component

Executed on the "input" event.


[View source]
def solve #

Calculates the layout dimensions. This runs each time the screen is rendered

def width=(size) #

Changes the width of the display
