<B>image create compound </B></I>?<I>name</I></B>? ?<I>options</I></B>?

</pre><HR>

</pre><H3>DESCRIPTION</H3>

<P>

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 <B>-image</B></I> 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 <B>button(n)</B></I> widget.

</pre><H3>CREATING COMPOUND IMAGES</H3>

<P>

Like all images, compound images are created using the <B>image create</B></I>

command. Compound images support the following <I>options</I></B>:

<DL>

<DT> <B>-background <I>color</I></B>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <B>-borderwidth <I>pixels</I></B>

</I></B>

<DD> Specifies a non-negative value indicating the width of the 3-D border

drawn around the compound image.

</DL>

<DL>

<DT> <B>-font <I>font</I></B>

</I></B>

<DD> Specifies the default font for the text items in the compound image.

</DL>

<DL>

<DT> <B>-foreground <I>color</I></B>

</I></B>

<DD> Specifies the default foreground color for the bitmap and text items

in the compound image.

</DL>

<DL>

<DT> <B>-padx <I>value</I></B>

</I></B>

<DD> Specifies a non-negative value indicating how much extra space to

request for the compound image in the X-direction. The <I>value</I></B> may

have any of the forms acceptable to <B>Tk_GetPixels(3)</B></I>.

</DL>

<DL>

<DT> <B>-pady <I>value</I></B>

</I></B>

<DD> Specifies a non-negative value indicating how much extra space to

request for the compound image in the Y-direction.

</DL>

<DL>

<DT> <B>-relief <I>value</I></B>

</I></B>

<DD> Specifies the 3-D effect desired for the background of the compound

image. Acceptable values are <B>raised</B></I>, <B>sunken</B></I>, <B>flat</B></I>,

<B>ridge</B></I>, and <B>groove</B></I>.

</DL>

<DL>

<DT> <B>-showbackground <I>value</I></B>

</I></B>

<DD> 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.

</DL>

<DL>

<DT> <B>-window <I>pathName</I></B>

</I></B>

<DD> 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 <B>image create

compound</B></I> command and cannot be changed by the <B>configure</B></I> image

command.

</DL>

</pre><H3>IMAGE COMMAND</H3>

<P>

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:

<pre>

<I>imageName option </I></B>?<I>arg arg ...</I></B>?

</pre>

<I>Option</I></B> and the <I>arg</I></B>s

determine the exact behavior of the command. The following

commands are possible for compound images:

<DL>

<DT> <I>imageName <B>add line</B></I> ?<I>option value ...</I></B>?

</I></B>

<DD> Creates a new line at the bottom of the compound image. Lines support

the following <I>options</I></B>:

</DL>

<UL>

<DL>

<DT> <B>-anchor</B></I> value

</I></B>

<DD> Specifies how the line should be aligned along the horizontal axis.

When the values are <B>w</B></I>, <B>sw</B></I> or <B>nw</B></I>, the line is aligned

to the left. When the values are <B>c</B></I>, <B>s</B></I> or <B>n</B></I>, the line

is aligned to the middle.  When the values are <B>e</B></I>, <B>se</B></I> or

<B>ne</B></I>, the line is aligned to the right.

</DL>

<DL>

<DT> <B>-padx <I>value</I></B>

</I></B>

<DD> Specifies a non-negative value indicating how much extra space to

request for this line in the X-direction.

</DL>

</UL>

<DL>

<DT> <I>imageName <B>add <I>item-type</I></B> ?<I>option value ...</I></B>?

</I></B>

<DD> Creates a new item of the type <I>item-type</I></B> at the end of the last

line of the compound image. All types of items support

these following common <I>options</I></B>:

</DL>

<UL>

<DL>

<DT> <B>-anchor</B></I> value

</I></B>

<DD> Specifies how the item should be aligned along the vertical axis. When

the values are <B>n</B></I>, <B>nw</B></I> or <B>ne</B></I>, the item is aligned to

the top of the line. When the values are <B>c</B></I>, <B>w</B></I> or <B>e</B></I>,

the item is aligned to the middle of the line.  When the values are

<B>s</B></I>, <B>se</B></I> or <B>sw</B></I>, the item is aligned to the bottom of

the line.

</DL>

<DL>

<DT> <B>-padx <I>value</I></B>

</I></B>

<DD> Specifies a non-negative value indicating how much extra space to

request for this item in the X-direction.

</DL>

<DL>

<DT> <B>-pady <I>value</I></B>

</I></B>

<DD> Specifies a non-negative value indicating how much extra space to

request for this item in the Y-direction.

</DL>

<DL>

<DT> <I>item-type</I></B> can be any of the following:

</DL>

</UL>

<DL>

<DT> <I>imageName <B>add bitmap</B></I> ?<I>option value ...</I></B>?

space holders that add additional spaces between items inside a

compound image. Additional <I>options</I></B> accepted by the image type

are:

</DL>

<UL>

<DL>

</DL>

<DL>

<DT> <B>-width <I>value</I></B>

option determines how the lines line up with each other. <I>value</I></B>

must be one of <B>left</B></I>, <B>center</B></I>, or <B>right</B></I>.  <B>Left</B></I>

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.

</DL>

</UL>

<DL>

<DT> <I>imageName <B>cget</B></I> <I>option</I></B>

</I></B>

<DD> Returns the current value of the configuration option given by

<I>option</I></B> is specified, returns a list describing all of the

available options for <I>imageName</I></B> (see <B>Tk_ConfigureInfo</B></I> for

information on the format of this list).  If <I>option</I></B> is specified

with no <I>value</I></B>, 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 <I>option</I></B> is specified).  If

one or more <I>option-value</I></B> 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. <I>Option</I></B> may have any of the

values accepted by the <B>image create compound</B></I> command, except the

<B>-window</B></I> option

</DL>

</pre><H3>EXAMPLE</H3>

The following example creates a compound image with a bitmap and a

text string and places this image into a Tk <B>bitton(n)</B></I>

widget. Notice that the image must be created after the creation of

the window that it resides in.

<pre><code><code><code>

 button .b

 set img [image create compound -window .b]

 $img add line

 $img add bitmap -bitmap warning

 $img add space -width 8

 $img add text -text "Warning" -underline 0

 .b config -image $img

 pack .b
