The event's id.

See Also:: AWTEvent.getID(), AWTEvent.AWTEvent(java.lang.Object, int)

consumed

boolean consumed

Controls whether or not the event is sent back down to the peer once the source has processed it - false means it's sent to the peer; true means it's not. Semantic events always have a 'true' value since they were generated by the peer in response to a low-level event.

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.

This will be the same for lastLine, firstItem, lastItem.

See Also:: Component.dispatchEvent(java.awt.AWTEvent)

eventMask

long eventMask

The eventMask is ONLY set by subclasses via enableEvents. The mask should NOT be set when listeners are registered so that we can distinguish the difference between when listeners request events and subclasses request them. One bit is used to indicate whether input methods are enabled; this bit is set by enableInputMethods and is on by default.

See Also:: Component.enableInputMethods(boolean), AWTEvent

changeSupport

PropertyChangeSupport changeSupport

If any PropertyChangeListeners have been registered, the changeSupport field describes them.

Class java.awt.GridBagConstraints extends Object implements Serializable

serialVersionUID: -1000070633030801713L

Serialized Fields

gridx

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. 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.

See Also:: GridBagConstraints.clone(), GridBagConstraints.gridy, ComponentOrientation

gridy

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:: GridBagConstraints.clone(), GridBagConstraints.gridx

gridwidth

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:: GridBagConstraints.clone(), GridBagConstraints.gridheight

gridheight

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:: GridBagConstraints.clone(), GridBagConstraints.gridwidth

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.

See Also:: GridBagConstraints.clone(), GridBagConstraints.weighty

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.

See Also:: GridBagConstraints.clone(), GridBagConstraints.weightx

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 relvative 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:: GridBagConstraints.clone(), ComponentOrientation

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
