  • 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.

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) 

DGS = exports.dgs
addEventHandler( "onDgsMouseDown", getRootElement( ),
    function ( btn, x, y )
        if btn == "left" then
            clickedElement = source; -- store the clicked element in a global variable
            local elementPos = { DGS:dgsGetPosition( source, false ) };
            offsetPos = { x - elementPos[ 1 ], y - elementPos[ 2 ] }; -- get the offset position
        end
    end
);

addEventHandler( "onDgsMouseUp", 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
);
