public class drag_icon
extends icon
implements move_press_draggable

An icon (displayed image) object which can be dragged. (This could also be done by placing an icon in a drag_container, but since this was built first and is more compact, we leave it.)

Constructor Detail

drag_icon

public drag_icon(int x,
                 int y,
                 loaded_image img)

Full constructor.

Parameters:: int - x initial x position of the object.; int - y initial y position of the object.; loaded_image - img the image to display for the icon.

Method Detail

drag_start

public boolean drag_start(event evt,
                          int xv,
                          int yv,
                          int gx,
                          int gy,
                          java.lang.Object user_info)

Handle the start of a drag to the object.

Parameters:: event - evt the event "causing" the start of the drag.; int - xv the new x position of this object (in parent's coords).; int - yv the new y position of this object (in parent's coords).; int - gx the initial grab x position of the drag (in local coords).; int - gy the initial grab x position of the drag (in local coords).; Object - user_info information associated with this object at the time it requested the drag focus.

drag_feedback

public boolean drag_feedback(event evt,
                             int x_pos,
                             int y_pos,
                             int start_x,
                             int start_y,
                             int grab_x,
                             int grab_y,
                             java.lang.Object user_info)

Handle a movement during a drag. Here we just set our position to follow the event location.

Parameters:: event - evt the event "causing" the start of the drag.; int - x_pos the new x position of this object (in parent's coords).; int - y_pos the new y position of this object (in parent's coords).; int - start_x the initial grab x position of the drag (in local coords).; int - start_y the initial grab x position of the drag (in local coords).; int - grab_x the initial grab x position of the drag (in local coords).; int - grab_y the initial grab x position of the drag (in local coords).; Object - user_info information associated with this object at the time it requested the drag focus.

drag_end

public boolean drag_end(event evt,
                        int x_pos,
                        int y_pos,
                        int start_x,
                        int start_y,
                        int grab_x,
                        int grab_y,
                        java.lang.Object user_info)

Handle input corresponding to the end of a drag.

Parameters:: event - evt the event "causing" the start of the drag.; int - x_pos the new x position of this object (in parent's coords).; int - y_pos the new y position of this object (in parent's coords).; int - start_x the initial grab x position of the drag (in local coords).; int - start_y the initial grab x position of the drag (in local coords).; int - grab_x the initial grab x position of the drag (in local coords).; int - grab_y the initial grab x position of the drag (in local coords).; Object - user_info information associated with this object at the time it requested the drag focus.
