Class OverlayLayout
- LayoutManager, LayoutManager2, Serializable
A layout manager that lays out the components of a container one over
another.
The components take as much space as is available in the container, but not
more than specified by their maximum size.
The overall layout is mainly affected by the components
alignmentX and
alignmentY properties. All
components are aligned, so that their alignment points (for either
direction) are placed in one line (the baseline for this direction).
For example: An X alignment of 0.0 means that the component's alignment
point is at it's left edge, an X alignment of 0.5 means that the alignment
point is in the middle, an X alignment of 1.0 means, the aligment point is
at the right edge. So if you have three components, the first with 0.0, the
second with 0.5 and the third with 1.0, then they are laid out like this:
+-------+
| 1 |
+-------+
+-------+
| 2 |
+-------+
+---------+
| 3 +
+---------+
The above picture shows the X alignment between the components. An Y
alignment like shown above cannot be achieved with this layout manager. The
components are place on top of each other, with the X alignment shown above.

OverlayLayout
public OverlayLayout(Container target)
Creates a new OverlayLayout for the specified container.
target - the container to be laid out
getLayoutAlignmentX
public float getLayoutAlignmentX(Container target)
Returns the X alignment of the container that is laid out. This is
computed by the children's preferred sizes, taking their alignments into
account.
- getLayoutAlignmentX in interface LayoutManager2
- the X alignment of the container that is laid out
getLayoutAlignmentY
public float getLayoutAlignmentY(Container target)
Returns the Y alignment of the container that is laid out. This is
computed by the children's preferred sizes, taking their alignments into
account.
- getLayoutAlignmentY in interface LayoutManager2
- the X alignment of the container that is laid out
layoutContainer
public void layoutContainer(Container target)
Lays out the container and it's children.
The children are laid out one over another.
The components take as much space as is available in the container, but
not more than specified by their maximum size.

alignmentX and

The components are place on top of each other, with the X alignment shown
