java.lang.Object | +--java.awt.GridBagConstraints
GridBagConstraints
class specifies constraints
for components that are laid out using the
GridBagLayout
class.
GridBagLayout
, Serialized FormField Summary | |
int | anchor
This field is used when the component is smaller than its display area. |
static int | BOTH
Resize the component both horizontally and vertically. |
static int | CENTER
Put the component in the center of its display area. |
static int | EAST
Put the component on the right side of its display area, centered vertically. |
int | fill
This field is used when the component's display area is larger than the component's requested size. |
int | gridheight
Specifies the number of cells in a column for the component's display area. |
int | gridwidth
Specifies the number of cells in a row for the component's display area. |
int | gridx
Specifies the cell at the left of the component's display area, where the leftmost cell has gridx = 0 . |
int | gridy
Specifies the cell at the top of the component's display area, where the topmost cell has gridy = 0 . |
static int | HORIZONTAL
Resize the component horizontally but not vertically. |
Insets | insets
This field specifies the external padding of the component, the minimum amount of space between the component and the edges of its display area. |
int | ipadx
This field specifies the internal padding of the component, how much space to add to the minimum width of the component. |
int | ipady
This field specifies the internal padding, that is, how much space to add to the minimum height of the component. |
static int | NONE
Do not resize the component. |
static int | NORTH
Put the component at the top of its display area, centered horizontally. |
static int | NORTHEAST
Put the component at the top-right corner of its display area. |
static int | NORTHWEST
Put the component at the top-left corner of its display area. |
static int | RELATIVE
Specify that this component is the next-to-last component in its column or row ( gridwidth , gridheight ),
or that this component be placed next to the previously added
component (gridx , gridy ). |
static int | REMAINDER
Specify that this component is the last component in its column or row. |
static int | SOUTH
Put the component at the bottom of its display area, centered horizontally. |
static int | SOUTHEAST
Put the component at the bottom-right corner of its display area. |
static int | SOUTHWEST
Put the component at the bottom-left corner of its display area. |
static int | VERTICAL
Resize the component vertically but not horizontally. |
double | weightx
Specifies how to distribute extra horizontal space. |
double | weighty
Specifies how to distribute extra vertical space. |
static int | WEST
Put the component on the left side of its display area, centered vertically. |

public int gridx
gridx = 0
. The value
RELATIVE
specifies that the component be placed just
to the right of the component that was added to the container just
before this component was added.
The default value is RELATIVE
.
gridy
public int gridy
gridy = 0
. The value
RELATIVE
specifies that the component be placed just
below the component that was added to the container just before
this component was added.
The default value is RELATIVE
.
gridx
public int gridwidth
Use REMAINDER
to specify that the component be the
last one in its row. Use RELATIVE
to specify that the
component be the next-to-last one in its row.
The default value is 1.
gridheight
public int gridheight
Use REMAINDER
to specify that the component be the
last one in its column. Use RELATIVE
to specify that
the component be the next-to-last one in its column.
The default value is 1.
gridwidth
public double weightx
The grid bag layout manager calculates the weight of a column to
be the maximum weighty
of all the components in a
row. If the resulting layout is smaller horizontally than the area
it needs to fill, the extra space is distributed to each column in
proportion to its weight. A column that has a weight zero receives no
extra space.
If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.
The default value of this field is 0
.
weighty
public double weighty
The grid bag layout manager calculates the weight of a row to be
the maximum weightx
of all the components in a row.
If the resulting layout is smaller vertically than the area it
needs to fill, the extra space is distributed to each row in
proportion to its weight. A row that has a weight of zero receives no
extra space.
If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.
The default value of this field is 0
.
weightx
public int anchor
CENTER,
NORTH, NORTHEAST, EAST,
SOUTHEAST, SOUTH, SOUTHWEST,
WEST, and NORTHWEST.
The default value is CENTER
.
public int fill
The following values are valid for fill
:
NONE
: Do not resize the component.
HORIZONTAL
: Make the component wide enough to fill
its display area horizontally, but do not change its height.
VERTICAL
: Make the component tall enough to fill its
display area vertically, but do not change its width.
BOTH
: Make the component fill its display area
entirely.
The default value is NONE
.
public Insets insets
The default value is new Insets(0, 0, 0, 0)
.
public int ipadx
(ipadx * 2)
pixels.
The default value is 0
