gtk-icon-view-convert-widget-to-bin-window-coords (view x y)

view -- a gtk-icon-view widget
x -- an integer with the x coordinate relative to the widget
y -- an integer with the y coordinate relative to the widget

rx -- an integer with the bin window x coordinate
ry -- an integer with the bin window y coordinate

Converts widget coordinates to coordinates for the bin window, as expected by e.g. the function gtk-icon-view-path-at-pos.
