# parent :Widget

The widget's parent in the widget tree.

Type:

# size :Array.<number>

A 2d array containing the widget's xy size.

Type:
  • Array.<number>

# autoSize :Array.<number>

A 2d array specifying the xy size the widget relative to it's parent. Values can range from 0-1. If either the x or the y value is 0, that dimension will default to the value of size().

Type:
  • Array.<number>
Default Value:
  • [0,0]
Example:
myWidget.set({autoSize: [1,1]}); // The widget will be the same size as its parent.

# anchor :Array.<number>

A 2d array specifying the relative xy position of the widget within its parent. Values can range from 0-1. The actual position of a widget relative to its parent is determined by a combination of anchor, pivot, local, and border.

Type:
  • Array.<number>
Default Value:
  • [0,0]
Examples:
myWidget.set({anchor: [1,0]}); // Anchor the widget to the upper right corner of its parent.
myWidget.set({anchor: [0.5,1]}); // Anchor the widget to the center bottom of its parent.

# pivot :Array.<number>

A 2d array specifying the relative xy position in the widget that matches the parent's anchor. Values can range from 0-1. The actual position of a widget relative to its parent is determined by a combination of anchor, pivot, local, and border

Type:
  • Array.<number>
Default Value:
  • [0,0]
Examples:
myWidget.set({anchor: [0.5,0.5], pivot: [0.5,0.5]}); // The center of the widget is exactly in the center of its parent.
myWidget.set({anchor: [1,0.25], pivot: [1,0]}); // The top left corner of the widget is 25% of the way down the parent's right side.

# local :Array.<number>

A 2d array specifying the xy pixel offset of the widget relative to its parent. The actual position of a widget relative to its parent is determined by a combination of anchor, pivot, local, and border.

Type:
  • Array.<number>
Default Value:
  • [0,0]
Example:
myWidget.set({anchor: [0,1], pivot: [0,1], local: [20,-20]}); // Inset the widget 20 pixels from the lower-left corner of its parent.

# border :Array.<number>

A 4d array specifying pixel insets to be applied when calculating the edges of the widget relaitve to its parent. The values are [left,top,right,bottom] and are always positive. The actual position of a widget relative to its parent is determined by a combination of anchor, pivot, local, and border.

Type:
  • Array.<number>
Default Value:
  • [0,0,0,0]
Example:
myWidget.set({autoSize: [1,1], border: [20,20,20,20]}); // The widget fills its parent with an inset of 20 pixels all around.

# visible :boolean

The visibility of the widget. Hidden widgets can't be interacted with. The visibility of a parent affects all its children.

Type:
  • boolean
Default Value:
  • true
Example:
myWidget.set({visible: false}); // Hides the widget and its children.

# color :Array.<number>

A 3d array specifying the rgb color of a widget. Not all widgets use this property, but enough do that its worth putting in the base class.

Type:
  • Array.<number>
Default Value:
  • [0,0,0]
Example:
myWidget.set({color: [0,1,0]}); // Sets the color to green.

# scale :Array.<number>

The widget's relative scale. A parent passes its scale on to its children. Usually you just want to leave the scale set to 1 and control the layout of your UI using the widget's other parameters. However, it can be useful if you want to create an interface that dynamically adapts to different window sizes.

Type:
  • Array.<number>
Default Value:
  • 1
Example:
myWidget.set({color: [0,1,0]}); // Sets the color to green.

# width :number

Ignored unless the widget is placed inside a horizontal widget. This allows you to override the horizontal widget's automatic scaling.

Type:
  • number

# height :number

Ignored unless the widget is placed inside a vertical widget. This allows you to override the vertical widget's automatic scaling.

Type:
  • number

Methods

# set(optionsopt)

Sets one or more properties. Set is called by the widget's constructor to set the widget's properties on instantiation.

Parameters:
Name Type Attributes Description
options object <optional>

An options object that contains the properties to be set.
Example 
myWidget.set({visible: false});
