viewport

An object containing information about the user’s viewport, e.g. browser window.

viewport?: ViewportContext

Notes

• You can use app.viewport directly, or using a binding (bound to "viewport", since all views and activities are ultimately attached to the global application context, i.e. app).
• Refer to ViewportContext for available properties of app.viewport.

Examples

// Use the viewport size in code:
if (app.viewport.portrait) {
  // ... do something in portrait mode
}

// Use the viewport size in a view:
ui.cell(
  { hidden: bound("!viewport.portrait") }
  // ... portrait cell content
)
