ttk_image - Define an element based on an image








ttk::style element create name image
    imageSpec ?options?










The image element factory creates a new element in the
    current theme whose visual appearance is determined by Tk images.
    imageSpec is a list of one or more elements. The first element is the
    default image name. The rest of the list is a sequence of statespec /
    value pairs specifying other images to use when the element is in a
    particular state or combination of states.








Valid options are:



  

  
padding is a list of up to four integers, specifying the left, top,
      right, and bottom borders, respectively. If fewer than four elements are
      specified, bottom defaults to top, right defaults to
      left, and top defaults to left. In other words, a
      list of three numbers specify the left, vertical, and right border; a list
      of two numbers specify the horizontal and the vertical border; a single
      number specifies the same border all the way around the element. See
      IMAGE STRETCHING, below.

  

  
Specifies a minimum height for the element. If less than zero, the base
      image's height is used as a default.

  

  
Specifies the element's interior padding. The padding is a list of up to
      four length specifications left top right bottom. If fewer than
      four elements are specified, bottom defaults to top,
      right defaults to left, and top defaults to
      left. In other words, a list of three numbers specify the left,
      vertical, and right padding; a list of two numbers specify the horizontal
      and the vertical padding; a single number specifies the same padding all
      the way around the widget. Defaults to -border if not
    specified.

  

  
Specifies how the image is placed within the final parcel. spec
      contains zero or more characters “n”, “s”,
      “w”, or “e”.

  

  
Specifies a minimum width for the element. If less than zero, the base
      image's width is used as a default.










If the element's allocated parcel is larger than the image, the
    image will be placed in the parcel based on the -sticky option. If
    the image needs to stretch horizontally (i.e., -sticky ew) or
    vertically (-sticky ns), subregions of the image are replicated to
    fill the parcel based on the -border option. The -border
    divides the image into 9 regions: four fixed corners, top and left edges
    (which may be tiled horizontally), left and right edges (which may be tiled
    vertically), and the central area (which may be tiled in both
  directions).
