Function Control.setAnchorAndMargin
Works the same as setAnchor, but instead of keep_margin argument and automatic update of margin, it allows to set the margin offset yourself (see setMargin).
void setAnchorAndMargin
(
const(long) margin,
const(double) anchor,
const(double) offset,
const(bool) push_opposite_anchor = false
) nothrow @nogc;
