gtk:scale-layout-offsets (scale)

scale -- a gtk:scale widget
x -- an integer for the x offset of the Pango layout
y -- an integer for the y offset of the Pango layout

Obtains the coordinates where the scale will draw the Pango layout representing the text in the scale. Remember when using the pango:layout functions you need to convert to and from pixels using the pango:pixels function or the pango:+scale+ constant. If the draw-value property is nil, the return values are undefined.
