AI-generated Key Takeaways

• widget.style() returns an ActiveDictionary that can be used to get and set the widget's style properties.

• Many CSS-like properties are supported for styling widgets, such as width, height, color, fontSize, and more.

• Custom layout properties like stretch and position are also supported for advanced positioning.

• ActiveDictionaries are mutable and allow for dynamically updating widget styles after creation.

• Styles can be initially defined during widget creation and later modified using the style() method and its associated set() method.

Properties which behave like their CSS counterparts:

  - height, maxHeight, minHeight (e.g. '100px')

  - width, maxWidth, minWidth (e.g. '100px')

  - padding, margin (e.g. '4px 4px 4px 4px' or simply '4px')

  - color, backgroundColor (e.g. 'red' or '#FF0000')

  - border (e.g. '1px solid black')

  - borderColor (e.g. 'red black blue #FF0000')

  - borderRadius (e.g. '10px')

  - borderStyle (e.g. 'solid dashed none dotted')

  - borderWidth (e.g. '1px 0px 1px 0px')

  - fontSize (e.g. '24px')

  - fontStyle (e.g. 'italic')

  - fontWeight (e.g. 'bold' or '100')

  - fontFamily (e.g. 'monospace' or 'serif')

  - textAlign (e.g. 'left' or 'center')

  - textDecoration (e.g. 'underline' or 'line-through')

  - whiteSpace (e.g. 'nowrap' or 'pre')

  - shown (true or false)

Supported custom layout properties (see ui.Panel.Layout documentation):

  - stretch ('horizontal', 'vertical', 'both')

  - position ('top-right', 'top-center', 'top-left', 'bottom-right', ...)

Examples

// Define a UI widget and add it to the map.
var widget = ui.Label({
  value: 'A label',
  style: {width: '400px', height: '200px', fontSize: '40px', color: '484848'}
});
Map.add(widget);

// View the UI widget's style properties; an ActiveDictionary.
print(widget.style());

// ActiveDictionaries are mutable; set a style property.
widget.style().set('backgroundColor', 'lightgray');
print(widget.style());

// Define the UI widget's style ActiveDictionary as a variable.
var widgetStyle = widget.style();
print(widgetStyle);

// Set the UI widget's style properties from the ActiveDictionary variable.
widgetStyle.set({border: '5px solid darkgray'});
print(widgetStyle);
