All graphical objects listed in Tk Canvas Objects can be animated. The object changes colour, or their image depending on the »state« property. Possible states are: »hidden«, »normal«, »active« and »disabled«. An image object thus may display three different icons, depending on its state.
The default palette for canvas objects is shown in Figure 6.1, “The Tk Canvas Palette”. The ellipsis (...) denotes that the item starts an »insert mode«. This insert mode is terminated either by turning it off –implemented through a checkbutton with on and off logic– or by selecting another object –auto off.
