  • firstLine

    Component firstLine
    A relative positioning constant, that can be used instead of north, south, east, west or center. mixing the two types of constants can lead to unpredicable results. If you use both types, the relative constants will take precedence. For example, if you add components using both the NORTH and BEFORE_FIRST_LINE constants in a container whose orientation is LEFT_TO_RIGHT, only the BEFORE_FIRST_LINE will be layed out. This will be the same for lastLine, firstItem, lastItem.

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.

  • weightx

    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.

  • weighty

    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.

  • anchor

    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:

  • fill

    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.

  • ipadx

    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:

    double[] rowWeights
    This field holds the overrides to the row weights. If this field is non-null the values are applied to the gridbag after all of the rows weights have been calculated. If rowWeights[i] > weight for row i, then row i is assigned the weight in rowWeights[i]. If rowWeights has more elements than the number of rows, the excess elements are ignored - they do not cause more rows to be created.

• Serialization Methods

  • readResolve

    private java.lang.Object readResolve()
    The design of the SystemColor class assumes that the SystemColor object instances stored in the static final fields above are the only instances that can be used by developers. This method helps maintain those limits on instantiation by using the index stored in the value field of the serialized form of the object to replace the serialized object with the equivalent static object constant field of SystemColor. See the SystemColor.writeReplace() method for more information on the serialized form of these objects.

  • writeReplace

    private java.lang.Object writeReplace() throws java.io.ObjectStreamException
    Returns a specialized version of the SystemColor object for writing to the serialized stream.

    Serial Data:

    The value field of a serialized SystemColor object contains the array index of the system color instead of the rgb data for the system color. This index is used by the SystemColor.readResolve() method to resolve the deserialized objects back to the original static constant versions to ensure unique instances of each SystemColor object.
