The tile widgets let you create textured backgrounds. The texture
    is a Tk image which is tiled over the entire background of the widget. The
    offset of the tile usually aligns with the toplevel window so that all
    sub-tiles line up. However, image names containing an exlamation
    "!" (ususally as the last char) are tiled absolutely.








With the advent of Tk 4.0, images are now easy to create and use
    in applications. Images add interest to applications and they convey more
    information. But one area where Tk hasn't taken advantage of images is using
    images as textures for widgets. Since tiling is a standard feature of
    windowing systems, it's very easy to use images as textures.


Note: Wize now adds a -tile option to Tk widgets natively.
    However, these are retained to provide the -shadow option.


Tiled widgets take the standard Tk 4.0 widgets and add tiling
    configuration options to them. Textures are specified by the name of the
    image you wish to be tiled across the background of the widget.








To add tiling to a widget, you simply create an image using Tk's
    image command and use the image name as the value for the
    -tile configuration option of the widget.





image create photo my_texture -file tan_paper.gif
blt::tile::frame .f -tile my_texture




The image my_texture is added to the frame. If
    my_texture is updated, so will the widget background.





image create photo my_texture -file rain.gif




The tile widget commands reside in the "blt::tile"
    namespace, so as not to collide with the normal Tk widgets. An easy way to
    add tiling to existing programs is to import the tile widget commands into
    the global namespace.





image create photo my_texture -file tan_paper.gif
namespace import -force blt::tile::*
frame .f -tile my_texture




To use one image for all texturing, you can use the
    "Tile" option class name to specify the same image for all tile
    widgets.





image create photo my_texture -file tan_paper.gif
option add *Tile my_texture












The following configurations options are added to the widgets. If
    a -tile or -activetile option is specified, it
    overrides the background color of the widget.



  

  
Specifies a textured background to display when the widget is active. This
      option is available for the tilebutton, tilecheckbutton,
      tileradiobutton, and tilescrollbar widgets. Image is
      the name an image created using Tk's image command. The background
      of the widget is tiled with image. If image is
      "", then the active background color is displayed. The
      default is "".

  

  
Specifies a textured background to display for the widget. Image is
      the name an image created using Tk's image command. The background
      of the widget is tiled with image. If image is
      "", then the normal background color is displayed. The
      default is "".

  

  
Set shadow for text.

  

  
Support for rotating text in degrees, eg. 90, 180.

  

  
Specify the size of check/radio button indicator.

  

  
Give a list of 0, or 2-9 images to use for the indicators. The first three
      are for normal,selected,tristate. The next three repeat but for the active
      state. The next three repeat but for the disabled state.

  

  

  

  

  

  
A border image that resizes to fit the widget.

  

  
Set to -1 to perform inner rather than outer mirror.
