NAME
compound - multi-line compound image type.
SYNOPSIS
image create compound ?name? ?options?
DESCRIPTION
Compound image types can be used to create images that consists of multiple horizontal
lines; each line is composed of a series of items (texts, bitmaps, images or spaces)
arranged from left to right. Compound images are mainly used to embed complex drawings
into widgets that support the -image option. As shown in the EXAMPLE section below, a
compound image can be used to display a bitmap and a text string simutaneously in a TK
button(n) widget.
CREATING COMPOUND IMAGES
Like all images, compound images are created using the image create command. Compound
images support the following options:
-background color
Specifies the background color of the compound image. This color is also used as
the default background color for the bitmap items in the compound image.
-borderwidth pixels
Specifies a non-negative value indicating the width of the 3-D border drawn around
the compound image.
-font font
Specifies the default font for the text items in the compound image.
-foreground color
Specifies the default foreground color for the bitmap and text items in the
compound image.
-padx value
Specifies a non-negative value indicating how much extra space to request for the
compound image in the X-direction. The value may have any of the forms acceptable
to Tk_GetPixels(3).
-pady value
Specifies a non-negative value indicating how much extra space to request for the
compound image in the Y-direction.
-relief value
Specifies the 3-D effect desired for the background of the compound image.
Acceptable values are raised, sunken, flat, ridge, and groove.
-showbackground value
Specifies whether the background and the 3D borders should be drawn. Must be a
valid boolean value. By default the background is not drawn and the compound image
appears to have a transparent background.
-window pathName
Specifies the window in which the compound image is displayed. One compound image
can be displayed in only one window. When that window is destroyed, the compound
image is automatically destroyed as well. This option must be specified when
calling the image create compound command and cannot be changed by the configure
image command.
IMAGE COMMAND
When a compound image is created, Tk also creates a new command whose name is the same as
the image. This command may be used to invoke various operations on the image. It has the
following general form:
imageName option ?arg arg ...?
Option and the args determine the exact behavior of the command. The following commands
are possible for compound images:
imageName add line ?option value ...?
Creates a new line at the bottom of the compound image. Lines support the following
options:
-anchor value
Specifies how the line should be aligned along the horizontal axis. When
the values are w, sw or nw, the line is aligned to the left. When the values
are c, s or n, the line is aligned to the middle. When the values are e, se
or ne, the line is aligned to the right.
-padx value
Specifies a non-negative value indicating how much extra space to request
for this line in the X-direction.
imageName add item-type ?option value ...?
Creates a new item of the type item-type at the end of the last line of the
compound image. All types of items support these following common options:
-anchor value
Specifies how the item should be aligned along the vertical axis. When the
values are n, nw or ne, the item is aligned to the top of the line. When the
values are c, w or e, the item is aligned to the middle of the line. When
the values are s, se or sw, the item is aligned to the bottom of the line.
-padx value
Specifies a non-negative value indicating how much extra space to request
for this item in the X-direction.
-pady value
Specifies a non-negative value indicating how much extra space to request
for this item in the Y-direction.
item-type can be any of the following:
imageName add bitmap ?option value ...?
Creates a new bitmap item of at the end of the last line of the compound image.
Additional options accepted by the bitmap type are:
-background color
Specifies the background color of the bitmap item.
-bitmap name
Specifies a bitmap to display in this item, in any of the forms acceptable
to Tk_GetBitmap(3).
-foreground color
Specifies the foreground color of the bitmap item.
imageName add image ?option value ...?
Creates a new image item of at the end of the last line of the compound image.
Additional options accepted by the image type are:
-image name
Specifies an image to display in this item. name must have been created with
the image create command.
imageName add space ?option value ...?
Creates a new space item of at the end of the last line of the compound image.
Space items do not display anything. They just acts as space holders that add
additional spaces between items inside a compound image. Additional options
accepted by the image type are:
-width value
Specifies the width of this space. The value may have any of the forms
acceptable to Tk_GetPixels(3).
-height value
Specifies the height of this space. The value may have any of the forms
acceptable to Tk_GetPixels(3).
imageName add text ?option value ...?
Creates a new text item of at the end of the last line of the compound image.
Additional options accepted by the text type are:
-background color
Specifies the background color of the text item.
-font name
Specifies the font to be used for this text item.
-foreground color
Specifies the foreground color of the text item.
-justify value
When there are multiple lines of text displayed in a text item, this option
determines how the lines line up with each other. value must be one of left,
center, or right. Left means that the lines' left edges all line up, center
means that the lines' centers are aligned, and right means that the lines'
right edges line up.
-text string
Specifies a text string to display in this text item.
-underline value
Specifies the integer index of a character to underline in the text item. 0
corresponds to the first character of the text displayed in the text item, 1
to the next character, and so on.
-wraplength value
This option specifies the maximum line length of the label string on this
text item. If the line length of the label string exceeds this length, it is
wrapped onto the next line, so that no line is longer than the specified
length. The value may be specified in any of the standard forms for screen
distances. If this value is less than or equal to 0 then no wrapping is
done: lines will break only at newline characters in the text.
imageName cget option
Returns the current value of the configuration option given by option. Option may
have any of the values accepted by the image create compound command.
imageName configure ?option? ?value option value ...?
Query or modify the configuration options for the image. If no option is specified,
returns a list describing all of the available options for imageName (see
Tk_ConfigureInfo for information on the format of this list). If option is
specified with no value, then the command returns a list describing the one named
option (this list will be identical to the corresponding sublist of the value
returned if no option is specified). If one or more option-value pairs are
specified, then the command modifies the given option(s) to have the given
value(s); in this case the command returns an empty string. Option may have any of
the values accepted by the image create compound command, except the -window option
EXAMPLE
The following example creates a compound image with a bitmap and a text string and places
this image into a Tk bitton(n) widget. Notice that the image must be created after the
creation of the window that it resides in.
set btn [button .b] set img [image create compound -window $btn] $img add line $img add
bitmap -bitmap warning $img add space -width 8 $img add text -text "Warning" -underline 0
$btn config -image $img pack $btn
