Camera Control for Pan3D - Movement - onControls


I would like to programm a camera control with my own ui-elements.

I found moveUp, moveDown, moveLeft, moveright, movebackward, moveforward, zoomIn, zoomOut
as functions on the camera, but i didn’t find a function for pan, like it is done via mouse event, i.E. LEFT_Drag.

Could anyone help ?
