The ANIMATEDPANE component is a normal PANE container with the extra feature, that a certain animation is triggered if the value of CURTAINFLASH changed. The animtaion is a coloring of the whole area, which is taken back within a certain period of time. The color can be explicitly defined using attribute CURTAINCOLOR.

Please note: for doing PANE-based animations there is a nicer way to do so in the meantime. Please check component CAPTUREANIMATOR - which not only allows some flashing with a certain color, but also allows to define more complex transformations (shrinking, rotations, etc.)
