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 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, 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 background of the widget is tiled with image. If image is "", then
the normal background color is displayed. The default is "".
