Class VerticalLayout
- LayoutManager, Serializable
public class VerticalLayout
implements LayoutManager, Serializable
A vertical layout manager similar to java.awt.FlowLayout. Like FlowLayout
components do not expand to fill available space except when the horizontal
alignment is BOTH
in which case components are stretched
horizontally. Unlike FlowLayout, components will not wrap to form another
column if there isn't enough space vertically. VerticalLayout can optionally
anchor components to the top or bottom of the display area or center them
between the top and bottom. Revision date 04 April 1999
static int | BOTH - The horizontal alignment constant that designates stretching the
component horizontally.
|
static int | BOTTOM - The anchoring constant that designates anchoring to the bottom of the
display area.
|
static int | CENTER - The horizontal alignment constant that designates centering.
|
static int | LEFT - The horizontal alignment constant that designates left justification.
|
static int | RIGHT - The horizontal alignment constant that designates right justification.
|
static int | TOP - The anchoring constant that designates anchoring to the top of the
display area.
|
VerticalLayout() - Constructs an instance of VerticalLayout with a vertical vgap of 5
pixels, horizontal centering and anchored to the top of the display area.
|
VerticalLayout(int vgap) - Constructs a VerticalLayout instance with horizontal centering, anchored
to the top with the specified vgap.
|
VerticalLayout(int vgap, int alignment) - Constructs a VerticalLayout instance anchored to the top with the
specified vgap and horizontal alignment.
|
VerticalLayout(int vgap, int alignment, int anchor) - Constructs a VerticalLayout instance with the specified vgap, horizontal
alignment and anchoring

to the top with the specified vgap.
vgap
- an int value indicating the vertical seperation of the
components
VerticalLayout
public VerticalLayout(int vgap,
int alignment)

specified vgap and horizontal alignment.
vgap
- an int value indicating the vertical seperation of the
componentsalignment
- an int value which is one of RIGHT, LEFT,
CENTER, BOTH
for the horizontal alignment.
