NAME

       Tk::Compound - Create multi-line compound images.

SYNOPSIS

           use Tk::Compound;
           $image = $widget->Compound(name,options);
           $image->Line(options);
           $image->Text(options);
           $image->Bitmap(options);
           $image->Image(options);
           $image->Space(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 widget.

       Compound images can only be used on windows on the same display as, and with the same
       pixel depth and visual as the $widget used to create them.

CREATING COMPOUND IMAGES

       Compounds are created using $widget->Compound.  Compounds 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.

IMAGE COMMAND

       When a compound image is created, Tk also creates a new object.  This object supports the
       configure and cget methods described in Tk::options which can be used to enquire and
       modify the options described above.

       The object also supports the following methods:

       $compound->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.

       $compound->Itemtype?(option = value ...>)?
           Creates a new item of the type Itemtype 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:
       $compound->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.

       $compound->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.

       $compound->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).

       $compound->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.

EXAMPLE

       The following example creates a compound image with a bitmap and a text string and places
       this image into a Button(n) widget. Notice that the image must be created using the widget
       that it resides in.

         my $b = $parent->Button;
         my $c = $b->Compound;
         $b->configure(-image => $c);
         $c->Line;
         $c->Bitmap(-bitmap => 'warning');
         $c->Space(-width => 8);
         $c->Text(-text => "Warning", -underline => 0);
         $b->pack;
