We can use the stair displayer displaying the gold stairs as an example. We can create this displayer by using the following code:
IlvPalette* palette = dpy->getPalette(dpy->getColor("gold"),
dpy->getColor("red"),
0,0,0,0,2);
IlvStairChartDisplayer* displayer = new IlvStairChartDisplayer(palette);
Note: By default, the stairs are outlined with the foreground color and filled with the background color of the defined palette. They will be displayed only with the outline if the Drawn Filled property is set to IlvFalse.
