Class ViewportLayout

class
ViewportLayout
extends Object
implements LayoutManager, Serializable
The default layout for {@link JViewport}. The viewport makes its view the
same size as itself, but not smaller than its minimum size.
If the port extends extends into space past the edge of the view,
this layout manager moves the port up or to the left, in view space, by the
amount of empty space (keep the lower and right edges lined up).
public ViewportLayout()
The method is not used with this manager.
public void layoutContainer(
Container parent)
Layout the view and viewport to respect the following rules. These are not
precisely the rules described in sun's javadocs, but they are the rules
which sun's swing implementation follows, if you watch its behavior:
- If the port is smaller than the view, leave the view at its current
size.
- If the view is smaller than the port, the view is top aligned.
- If the view tracks the port size, the view position is always zero and
the size equal to the viewport size
- In {@link JViewport#setViewSize(Dimension)}, the view size is never
set smaller that its minimum size.

Get the minimum layout size. Normally this method returns the value,
returned by the view method {@link Component#getMinimumSize()}.
If the view is not set, the zero size is returned.
Parameters: parent the viewport
Returns: the minimum layout size.
Get the preferred layout size. If the view implements
{@link Scrollable}, this method returns
{@link Scrollable#getPreferredScrollableViewportSize}.
Otherwise, it returns {@link Component#getPreferredSize()}.
Returns: the preferred layout size, as described about.
public void removeLayoutComponent(
Component c)
The method is not used with this manager.
