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

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 tileframe .frame -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 An easy way to add tiling to existing programs is to rename the tile widget commands, overwriting the standard Tk widgets. foreach cmd { button checkbutton frame label radiobutton |
scrollbar } { | ||
|
if [info commands tile$cmd] { |
rename $cmd "" | ||
|
rename tile$cmd $cmd |
} }
option add *Tile my_texture
image create photo my_texture -file tan_paper.gif You can then set the widget option resource, specifying the tile.
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 "".
