DESCRIPTION

       The tile widgets let you create textured backgrounds.  The texture is a Tk image which is tiled over the entire background of the widget.

INTRODUCTION

       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.

       The  tile 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.

EXAMPLE

       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 configura-
       tion 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

OPTIONS

       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.

       -activetile image
              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 "".

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