// Component declaration
var component = {

    // Component ID
    id: 'COMPONENT_ID',

    // Positioning
    // You can define specific display size and if the display size is not specified then the component tries to find a size for larger display
    offset: {
        xs: { x: 1, y: 1, width: 6, height: 6 }, // Number means the position in the grid, so e.g. width "2" takes "2" columns in X axis
        lg: { x: 1, y: 1, width: 6, height: 6 }
    },

    // Default settings
    actions: { move: true, remove: true, resize: true, resizeX: true, resizeY: true, resizeP: false, settings: true },
    // resizeP means: resize "proportionally"

    // Can disable header (default: true)
    header: true,

    // Can delay displaying (in "ms", default: config.delay)
    delay: 0,

    // Custom properties which will be assigned to the instance
    template: Object,
    config: Object,

PUSH('components', component);

Methods:

• SETTER('dashboard/send', id, body) sends data to all widgets which contain data delegate
  • id {String}
    • null sends to all components
    • @component sends to the specific components according to the component name
    • string sends to a specific component according to the identifier
• SETTER('dashboard/call', method_name, [a], [b], [c], [d]) executes a method in each widget
• RETURN('dashboard/pixel') returns a size of the pixel (square)
• RETURN('dashboard/display') returns a current display width

Good to know:

• component adds classes to component's body:
  • d_colNUMBER determins count of taken columns e.g. d_col2
  • d_rowNUMBER determins count of taken rows e.g. d_row3
  • d_square the component has same width/height
  • d_vertical the component has only 1 step of width and more than 1 steps of height
  • d_horizontal the component has only 1 step of height and more than 1 steps of width
