{{Client event}}
__NOTOC__
This event is fired when the user releases his mouse button when on top of a DGS element.

==Parameters==
<syntaxhighlight lang="lua">
string button, int absoluteX, int absoluteY
</syntaxhighlight>
*'''button:''' the name of the mouse button that was released on a DGS element, can be ''left'', ''right'', or ''middle''.
*'''absoluteX:''' the X position of the mouse cursor, in pixels, measured from the left side of the screen.
*'''absoluteY:''' the Y position of the mouse cursor, in pixels, measured from the top of the screen.

==Source==
The [[event system#Event source|source]] of this event is the DGS element on top of which the mouse button was released.

==Example==
This example show how to add very basic ''click'n'drag'' feature for DGS elements (only for those which parent element is dgs-root)
<syntaxhighlight lang="lua">
DGS = exports.dgs
addEventHandler( "onDgsMouseUp", getRootElement( ),
function ( btn, x, y )
if btn == "left" then
clickedElement = source; -- store the clicked element in a global variable
local elementPos = { guiGetPosition( source, false ) };
offsetPos = { x - elementPos[ 1 ], y - elementPos[ 2 ] }; -- get the offset position
end
end
);

addEventHandler( "onDgsMouseDown", getRootElement( ),
function ( btn, x, y )
if btn == "left" then
clickedElement = nil;
end
end
);

addEventHandler( "onDgsMouseMove", getRootElement( ),
function ( x, y )
if clickedElement then
DGS:dgsSetPosition( clickedElement, x - offsetPos[ 1 ], y - offsetPos[ 2 ], false );
end
end
);
