public class FlowLayout extends Layout
Constructor and Description |
---|
FlowLayout()
Creates a new instance of FlowLayout with left alignment
|
FlowLayout(int orientation)
Creates a new instance of FlowLayout with the given orientation one of
LEFT, RIGHT or CENTER
|
Modifier and Type | Method and Description |
---|---|
boolean |
equals(Object o)
Indicates whether some other object is "equal to" this one.
|
int |
getAlign()
Alignment of the flow layout, defaults to LEFT
|
Dimension |
getPreferredSize(Container parent)
Returns the container preferred size
|
int |
getValign()
Indicates vertical alignment within the flow layout
|
boolean |
isFillRows()
Indicates whether the layout manager should try to fill up the available space
in the row
|
boolean |
isValignByRow()
Returns whether vertical alignment is done internally or externally
|
void |
layoutContainer(Container parent)
Layout the given parent container children
|
void |
setAlign(int orientation)
Alignment of the flow layout, defaults to LEFT
|
void |
setFillRows(boolean fillRows)
Indicates whether the layout manager should try to fill up the available space
in the row
|
void |
setValign(int valign)
Indicates vertical alignment within the flow layout
|
void |
setValignByRow(boolean internal)
When set to true vertical alignment will be performed by row (components within the container will be aligned vertically to each other in the same row)
When set to false (which is default) vertical alignment relates to the alignment of this container in regards to external components
|
String |
toString()
Returns a string representation of the object.

Object
toString
method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@
', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())

The equals
method implements an equivalence relation
on non-null object references:
x
, x.equals(x)
should return
true
.
x
and y
, x.equals(y)
should return true
if and only if
y.equals(x)
returns true
.
x
, y
, and z
, if
x.equals(y)
returns true
and
y.equals(z)
returns true
, then
x.equals(z)
should return true
.
x
and y
, multiple invocations of
x.equals(y)
consistently return true
or consistently return false
, provided no
information used in equals
comparisons on the
objects is modified.
x
,
x.equals(null)
should return false
.
The equals
method for class Object
implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values x
and
y
, this method returns true
if and only
if x
and y
refer to the same object
(x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the
general contract for the hashCode
method, which states
that equal objects must have equal hash codes.
