Define an element based on an image
style create element name image imageName ?options?
The image element factory creates a new element
in the current theme whose visual appearance is determined
by a Tk image.
Valid options are:
-
-border padding
-
padding is a list of up to four integers, specifying
the left, top, right, and bottom borders, respectively.
See IMAGE STRETCHING, below.
-
-height height
- Specifies a minimum height for the element.
If less than zero, the base image's height is used as a default.
-
-map { statespec image.. }
- Specifies auxilliary images to use in different states.
Each statespec is a list of state names optionally
prefixed by an exclamation point, as in style map.
Each imageName is the name of a Tk image
defined with image create ....
When the element is displayed, each statespec is
tested in order, and the image corresponding to
the first matching statespec is used.
If none match, the base imageName is used.
-
-padding padding
- Specifies the element's interior padding. Defaults to
-border if not specified.
-
-sticky spec
- Specifies how the image is placed within the final parcel.
spec contains zero or more characters "n", "s", "w", or "e".
-
-width width
- Specifies a minimum width for the element.
If less than zero, the base image's width is used as a default.
If the element's allocated parcel is larger than the image,
the image will be placed in the parcel based on the -sticky option.
If the image needs to stretch horizontally (i.e., -sticky ew)
or vertically (-sticky ns),
subregions of the image are replicated to fill the parcel
based on the -border option.
The -border divides the image into 9 regions:
four fixed corners, top and left edges (which may be tiled horizontally),
left and right edges (which may be tiled vertically),
and the central area (which may be tiled in both directions).
