• text? - string

  The text content.

• width? - number

  the component width. the width in style is also supported. this prop will override the width in style prop.

• maxWidth? - number

  the component max width. the maxWidth in style is also supported. this prop will override the maxWidth in style prop. If the given width ( the width prop or width in style prop or the width of containerNode minus containerLeftSpace ) is greater than the max width, the max width will be used to calculate the show text.

• minWidth? - number

  the component min width. the minWidth in style is also supported. this prop will override the minWidth in style prop. If the given width ( the width prop or width in style prop or the width of containerNode minus containerLeftSpace ) is smaller than the min width, the min width will be used to calculate the show text.

• minFontSize? - number|string

  When specify, enable the auto font size mode. If the text size is too long for the container, reduce the font size until it fit the container or equal minFontSize. Support string with unit px, pt, % and number means px

• minFontSizeRadio? - number

  When specify, enable the auto font size mode. If the text size is too long for the container, reduce the font size until it fit the container or equal minFontSizeRadio * initialFontSize. Range from 0 to 1.

• style? - CSSProperties

  The component style.

• className? - string

  The component className.

• ellipsis? - ReactNode - <span> ...</span>

  The custom ellipsis component.

  callback when show text changed.

• flex? - boolean - false

  The flex mode. work well when the text is in a flex container and the browser support flex feature.

• containerNode? - Element | string

  the container node which use to calc the content width. The selector is also supported.

• containerLeftSpace? - number

  the content width is ( the width of containerNode or the node which container the component ) - containerLeftSpace

• containerLeftNodes? - string | Element | Element[]

  the nodes used to calc the containerLeftSpace. will be omitted if containerLeftSpace has been used. The selector is also supported.

The component require its width not depend on its content. Because its real content depends on its width. So a computed width should be provide. It can be provided by the width prop, the width in style prop or the width of containerNode prop. If the width prop is a percent value, one ancestor of the component should has a concrete width. The flex model is encouraged, because it support providing the width without specify concrete width.
