Edje Drag
Edje Part

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.

double *  dy 
)

Gets the dragable object 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.

See also edje_object_part_drag_value_set()

Gets the drag location values.

Parameters:
[in]partThe part name
[out]dxThe x value
[out]dyThe y value
Returns:
true on success, false otherwise
Since :
2.3
Examples:
edje-drag.c.
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.
