Hi Meritimer,

Place some items(like buttons ) on a form and put the following codes at form level triggers:

(1) When-new-form-instance trigger:

DECLARE
D BOOLEAN;
BEGIN
:GLOBAL.D:='FALSE';
END;

(2) When-mouse-down trigger:

DECLARE
I ITEM;
N NUMBER;
BEGIN
:GLOBAL.D:='TRUE';
I:=FIND_ITEM(:SYSTEM.MOUSE_ITEM);
:global.item:=i.id;
EXCEPTION
WHEN OTHERS THEN
MESSAGE('NO ITEM CLICKED');
:GLOBAL.D:='FALSE';
END;

(3) when-mouse-up trigger:

:GLOBAL.D:='FALSE';

(4) when-mouse-move trigger:

declare
i item;
p number;
P1 NUMBER;
begin
if :global.d='TRUE' then
i.id:=to_number(:global.item);
p:=get_item_property(i,x_pos);
set_item_property(i,x_pos,p+:system.mouse_x_pos);
p1:=get_item_property(i,y_pos);
set_item_property(i,y_pos,p1+:system.mouse_y_pos);
else
null;
end if;
end;

After writing the code run the form and select any item on the form click on it and now you can easily drag and drop this item.
These trigger impliment the drag and drop facility.
You can use it at any form.
