public int gridx
gridx=0.
The leading edge of a component's display area is its left edge for
a horizontal, left-to-right container and its right edge for a
horizontal, right-to-left container.
The value
RELATIVE specifies that the component be placed
immediately following the component that was added to the container
just before this component was added.
The default value is RELATIVE.
gridx should be a non-negative value.
clone(),
gridy,
ComponentOrientationpublic 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.
gridy should be a non-negative value.
clone(),
gridxpublic int gridwidth
Use REMAINDER to specify that the component's
display area will be from gridx to the last
cell in the row.
Use RELATIVE to specify that the component's
display area will be from gridx to the next
to the last one in its row.
gridwidth should be non-negative and the default
value is 1.
clone(),
gridheightpublic int gridheight
Use REMAINDER to specify that the component's
display area will be from gridy to the last
cell in the column.
Use RELATIVE to specify that the component's
display area will be from gridy to the next
to the last one in its column.
gridheight should be a non-negative value and the
default value is 1.
clone(),
gridwidthpublic double weightx
The grid bag layout manager calculates the weight of a column to
be the maximum weightx of all the components in a
column. 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 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 left and right edges.
The default value of this field is 0.
weightx should be a non-negative value.
clone(),
weightypublic double weighty
The grid bag layout manager calculates the weight of a row to be
the maximum weighty 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.
weighty should be a non-negative value.
clone(),
weightxpublic int anchor
There are two kinds of possible values: relative and
absolute. Relative values are interpreted relative to the container's
component orientation property while absolute values are not. The absolute
values are:
CENTER, NORTH, NORTHEAST,
EAST, SOUTHEAST, SOUTH,
SOUTHWEST, WEST, and NORTHWEST.
The relative values are: PAGE_START, PAGE_END,
LINE_START, LINE_END,
FIRST_LINE_START, FIRST_LINE_END,
LAST_LINE_START and LAST_LINE_END.
The default value is CENTER.
clone(),
ComponentOrientationpublic 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.
clone()public Insets insets
The default value is new Insets(0, 0, 0, 0).
clone()public int ipadx
ipadx pixels.
The default value is 0.
clone(),
ipadypublic int ipady
ipady pixels.
The default value is 0.

automatic source code generation tools.
