Tizen Native API  5.5

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.

Edje_Drag_Dir edje_object_part_drag_dir_get ( const Evas_Object obj,
const char *  part

Determines dragable directions.

The dragable directions are defined in the EDC file, inside the "dragable" section, by the attributes x and y. See the edcref for more information.

Parameters:
[in]partThe part name
Returns:
EDJE_DRAG_DIR_NONE: Not dragable EDJE_DRAG_DIR_X: Dragable in X direction EDJE_DRAG_DIR_Y: Dragable in Y direction EDJE_DRAG_DIR_XY: Dragable in X & Y directions 2.3
Eina_Bool edje_object_part_drag_page ( Evas_Object obj,

)

Pages x,y steps.

Pages x,y where the increment is defined by edje_object_part_drag_page_set().

Values for dx and dy are real numbers that range from 0 to 1.

Warning:
Paging is bugged!

Parameters:
[in]partThe part name
[in]dxThe x step
[in]dyThe y step
Returns:
true on success, false otherwise 2.3

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

Sets the page step increments.

Sets the x,y page step increment values.

Values for dx and dy are real numbers that range from 0 to 1, representing the relative size of the dragable area on that axis by which the part will be moved.

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.

Gets the drag location values.

Parameters:
[in]partThe part name
[out]dxThe x value
[out]dyThe y value
Returns:
true on success, false otherwise 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.

Parameters:
[in]partThe part name
[in]dxThe x value
[in]dyThe y value
