The PaneEffect property gives you complete control of a pane's visual appearance. Normal panes display their caption and image without modification. Dimmed and Disabled panes alter the caption and image to provide visual feedback. Dimmed panes simply gray the text and image to indicate that something is "Off." Disabled panes make the caption and image appear etched to indicate that something is unavailable or disabled. Invisible panes simply hide the caption and image. Animated panes cycle through the pane's image frames automatically at intervals based on the value of that pane's PaneAnimationDelay property.
