// Set the color in two steps. The setPalette() slot will not emit a signal
// with the current color setting. The reason is that setPalette() is used
// by the color selector dialog on startup. In the color selector dialog
// we normally want to display a startup color which we specify
// when the dialog is started. The slotSetPalette() slot below will
// set the palette and then use the information to emit a signal with the
// new color setting. It is only used by the combobox widget.
