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)
bounds
Rectangle - New bounds of the View.
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

(RRGGBB)#ffffffff
(AARRGGBB)
- RGB

- e.g.
- HSL
hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
- e.g.
hsl(200, 20%, 50%)
- e.g.
- HSLA
hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
- e.g.
hsla(200, 20%, 50%, 0.5)

- Similar a las palabras clave del Módulo de Color CSS Nivel 3, pero sensible a mayúsculas y minúsculas.
- e.g.
blueviolet

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