  - gridx
```
public int gridx
```
    Specifies the cell containing the leading edge of the component's display area, where the first cell in a row has gridx=0.

  - gridy
```
public int gridy
```
    Specifies the cell at the top of the component's display area, where the topmost cell has 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.
    
    See Also:
    clone(), gridx
  - gridwidth
```
public int gridwidth
```
    Specifies the number of cells in a row for the component's display area.
    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.
    
    See Also:
    clone(), gridheight
  - gridheight
```
public int gridheight
```
    Specifies the number of cells in a column for the component's display area.
    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.
    
    See Also:
    clone(), gridwidth
  - weightx
```
public double weightx
```
    Specifies how to distribute extra horizontal space.
    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.
    
    See Also:
    clone(), weighty
  - weighty
```
public double weighty
```
    Specifies how to distribute extra vertical space.
    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.
    
    See Also:
    clone(), weightx
  - anchor
```
public int anchor
```
    This field is used when the component is smaller than its display area. It determines where, within the display area, to place the component.
    There are three kinds of possible values: orientation relative, baseline relative and absolute. Orientation relative values are interpreted relative to the container's component orientation property, baseline relative values are interpreted relative to the baseline and absolute values are not. The absolute values are: CENTER, NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH, SOUTHWEST, WEST, and NORTHWEST. The orientation 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 baseline relative values are: BASELINE, BASELINE_LEADING, BASELINE_TRAILING, ABOVE_BASELINE, ABOVE_BASELINE_LEADING, ABOVE_BASELINE_TRAILING, BELOW_BASELINE, BELOW_BASELINE_LEADING, and BELOW_BASELINE_TRAILING. The default value is CENTER.
    
    See Also:
    clone(), ComponentOrientation
  - fill
```
public int fill
```
    This field is used when the component's display area is larger than the component's requested size. It determines whether to resize the component, and if so, how.
    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.
    See Also:
    clone()
  - insets
```
public 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.
    The default value is new Insets(0, 0, 0, 0).
    
    See Also:
    clone()
  - ipadx
```
public int ipadx
```
    This field specifies the internal padding of the component, how much space to add to the minimum width of the component. The width of the component is at least its minimum width plus ipadx pixels.
    The default value is 0.
    
    See Also:
    clone(), ipady
  - ipady
```
public int ipady
```
    This field specifies the internal padding, that is, how much space to add to the minimum height of the component. The height of the component is at least its minimum height plus ipady pixels.
