Arguments: split-bar
Returns the min-space-after
property of a split-bar
widget. The value may be set at creation time by passing the
:min-space-after
initarg to make-instance, or any time later by
call (setf
min-space-after).
This is the minimum space to maintain either below a horizontal
split-bar
or to the right
of of a vertical split-bar
.
The value is measured in pixels, and refers to the distance between
the split-bar
and either
another split-bar
or the
interior edge of the parent window.
The user will not be able to interactively drag
the split-bar
to where the
distance would be less than this minimum. This is to ensure that
enough space is left to display the contents of widgets that are moved
or resized by the split-bar
(see widgets-to-move and
widgets-to-resize).
The value should be a non-negative integer. The default value is zero,
which allows the user to drag the split-bar
so that it butts against the nearest
other split-bar
or the edge
of the window, but not to overlap it. The value
may be set at creation time by passing the :min-space-after initarg to
make-instance, or any time
later by call (setf min-space-after).
If this property, along with min-space-before, is not adequate for
constraining the dragging of a split-bar
, then an on-drag function could be supplied.
