Module Element

This is a description of what is expected in an element class.

IMPORTANT: Your class should inherit from the element class. This means that any methods defined on that class need to be compatible with or overridden by your class!

Functions

load (pop)	Optional: Called during pop.load() with a reference to Pop.Box.
wrap (pop)	Optional: Called during pop.load() to allow a custom wrapper function to be created for your element class.
update (dt)	Optional: Called from pop.update() if data.update and a child of pop.screen.
draw ()	Optional: Called from pop.draw() if data.draw and a child of pop.screen.
mousemoved (x, y, dx, dy)	Optional: Called from pop.mousemoved() if in LOVE >= 0.10.0 and your element is focused.
mousepressed (x, y, button)	Optional: Called from pop.mousepressed() if a mouse button was pressed over your element.

Tables

data	Every object has a data field with pre-defined values.

Fields

parent	The parent element of this element.
child	The child elements of this element.

Parameters:

mousemoved (x, y, dx, dy)

Optional: Called from pop.mousemoved() if in LOVE >= 0.10.0 and your element is focused.

Parameters:

• x integer The x coordinate of the mouse.
• y integer The y coordinate of the mouse.
• dx number The distance on the x axis the mouse was moved.
• dy number The distance on the y axis the mouse was moved.

Returns:

boolean Was the event handled?

mousepressed (x, y, button)

Optional: Called from pop.mousepressed() if a mouse button was pressed over your element.

Note: Your element must be visible (data.draw is true) for this method to be called.

Parameters:

• x integer The x coordinate of the mouse press.
• y integer The y coordinate of the mouse press.
• button string or integer The mouse button pressed. (Type varies by LÖVE version.)

Tables

• child table All child elements' data fields.
• x integer The left edge of your element.
• y integer The top edge of your element.
• w integer The width of your element.
• h integer The height of your element.
• update boolean Whether or not to update this element (and its children).
• draw boolean Whether or not to draw this element (and its children).

Fields

parent

The parent element of this element.

• parent Element or false Parent element.
