Class: View​

A basic native view.

Process: Main

View is an EventEmitter.

new View()​

Creates a new View.

Eventos de Instancia​

Objects created with new View emit the following events:

Event: 'bounds-changed'​

Emitted when the view's bounds have changed in response to being laid out. The new bounds can be retrieved with view.getBounds().

Métodos de Instancia​

Objects created with new View have the following instance methods:

view.addChildView(view[, index])​

  • view View - Child view to add.
  • index Integer (optional) - Index at which to insert the child view. Defaults to adding the child at the end of the child list.

Si el mismo View es agregado a un padre que ya lo contiene, será reordenado de manera que se convierta en el view superior.

view.removeChildView(view)​

  • view View - Child view to remove.

If the view passed as a parameter is not a child of this view, this method is a no-op.

view.setBounds(bounds)​

view.getBounds()​

Returns Rectangle - The bounds of this View, relative to its parent.

view.setBackgroundColor(color)​

  • color string - Color in Hex, RGB, ARGB, HSL, HSLA or named CSS color format. The alpha channel is optional for the hex type.

Examples of valid color values:

  • Hex
    • #fff (RGB)
    • #ffff (ARGB)
    • #ffffff (RRGGBB)
    • #ffffffff (AARRGGBB)
  • RGB
    • rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
      • e.g. rgb(255, 255, 255)
  • RGBA
    • rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
      • e.g. rgba(255, 255, 255, 1.0)
  • HSL
    • hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
      • e.g. hsl(200, 20%, 50%)
  • HSLA
    • hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
      • e.g. hsla(200, 20%, 50%, 0.5)
  • Nombre de color
    • Options are listed in SkParseColor.cpp
    • Similar a las palabras clave del Módulo de Color CSS Nivel 3, pero sensible a mayúsculas y minúsculas.
      • e.g. blueviolet or red

Note: Hex format with alpha takes AARRGGBB or ARGB, not RRGGBBAA or RGB.

view.setBorderRadius(radius)​

  • radius Integer - Border radius size in pixels.

Note: The area cutout of the view's border still captures clicks.

view.setVisible(visible)​

  • visible boolean - If false, the view will be hidden from display.

view.children Readonly​
