Spacing

As well as setting widgets to a fixed size, you can also introduce spaces by using the DDgui_space function :

DDgui_spacer([width%, height%])

If width% is given, then the next widget will attempt to be positioned after the given number of horizontal pixels.  A large width% value will introduce vertical spacing

A height% value usually has no affect on spacing.

Some examples :

DDgui_spacer(12,0)     DDgui_spacer(24,0)

DDgui_spacer()

DDgui_spacer cannot be added to a tab, as it has no ID.
