Detailed Description

Functions that deal with dragable parts.

To create a movable part it must be declared as dragable in EDC file. To do so, one must define a "dragable" block inside the "part" block.

These functions are used to set dragging properties to a part or get dragging information about it.

Enumeration Type Documentation

_Edje_Drag_Dir

enum _Edje_Drag_Dir

Directions in which a part can be dragged .

Enumerator
EDJE_DRAG_DIR_NONE	Part cannot be dragged.

Function Documentation

edje_object_part_drag_value_set()

Eina_Bool edje_object_part_drag_value_set	(	Evas_Object *	obj,
		const char *	part,
		double	dx,
		double	dy
	)

Sets the dragable object location.

Places the dragable object at the given location.

Values for dx and dy are real numbers that range from 0 to 1, representing the relative position to the dragable area on that axis.

This value means, for the vertical axis, that 0.0 will be at the top if the first parameter of y in the dragable part theme is 1, and at bottom if it is -1.

For the horizontal axis, 0.0 means left if the first parameter of x in the dragable part theme is 1, and right if it is -1.
