5 * @defgroup Panel Panel
7 * A panel is a type of animated container that contains subobjects. It
8 * can be expanded or contracted.
10 * Orientations are as follows:
11 * ELM_PANEL_ORIENT_TOP
12 * ELM_PANEL_ORIENT_BOTTOM
13 * ELM_PANEL_ORIENT_LEFT
14 * ELM_PANEL_ORIENT_RIGHT
15 * NOTE: Only LEFT and RIGHT orientations are implemented.
17 * THIS WIDGET IS UNDER CONSTRUCTION!
