icon-fill-colors

Arguments: line-graph-view

Returns the value of the icon-fill-colors property of a line-graph-view. The value may be set at creation time by passing the icon-fill-colors initarg, or any time later by calling (setf icon-fill-colors).

The colors that are used to draw the interior area of non-pixmap icons on a line-graph-view in a chart-widget. The value should be a sequence (list or vector) of RGB objects (see make-rgb) and/or symbols that are globally bound to RGB objects. The default value is a list returned by the following (see make-rgb for a list of predefined colors):

(list 'light-blue 'green 'light-red 'magenta 'cyan
      'light-gray 'gray 'yellow)

If the value is nil, then black is used to fill all icons. Otherwise, the first object in the chart-widget's sequence of chart-objects is drawn with the first fill color, the second object with the second color, and so on. If there are fewer colors in the list than there are chart-objects, then the drawing code will cycle back through the list of colors as needed.

This property is used only when the draw-icons property is true, the icons-filled property is t, and the icon-images property contains one or more non-pixmap elements. If icons-filled is :hollow then icons are filled with the body-background-color of the chart-widget. If icons-filled is :without-border, then icons are filled with the line-colors of the line-graph-view rather than the icon-fill-colors, because those typically darker colors look better when there are no icon borders.
