StatusBar
Extends Widget
The status bar is the area where notifications, status icons and device time are displayed. The singleton instance can be accessed via ui.statusBar.
Import this type with “const {StatusBar} = require('tabris');”
Properties
background
Type: Color
Background color of the status bar. Should be used in conjunction with the theme property to keep the status bar icons legible.
displayMode
Type: string, supported values: default, hide, float, default: default
Controls how the status bar is positioned relative to the ui.contentView. The value default places the content below the status bar. The hide option lets the status bar disappear, making more room for the content. The float option lets the content flow underneath the status bar. On Windows float is currently not supported and treated as hide.
height
read-only
Type: number
The height of the status bar in device independent pixel. Can be used in conjunction with the displayMode 'float' to offset the content as to not have it covered by the status bar.
This property can only be set on widget creation. Once set, it cannot be changed anymore.
theme
iOSAndroid
Type: string, supported values: default, light, dark, default: default
Defines the shade used on the status bar. A dark theme sets the foreground icons to be of a light color, whereas light sets the icons to a dark color. The theme should be set in conjunction with the background property for contrast. The value default selects the default theme that depends on the device and on the app. Available on iOS and Android 6+.
