_________________________________________________________________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 fea‐
ture 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 con‐
figuration 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 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
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, tilecheck‐
button, tileradiobutton, and tilescrollbar widgets. 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 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 background of the widget is tiled with image. If image is
"", then the normal background color is displayed. The default
is "".
