Page Summary

outlined_flag

• The widget's style() method returns an ActiveDictionary which can be modified to update the widget's styles.

• Supported style properties behave like their CSS counterparts, including properties for size, spacing, color, borders, text, and visibility.

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

• The style properties are accessed and modified using the widget's style() method, which returns a mutable ActiveDictionary.

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', ...)
