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.

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: Make the component fill its display area entirely.

The default value is NONE.

See Also:

GridBagConstraints.clone()

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:

The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Throws:

IOException - thrown by ObjectInputStream.

Writes default serializable fields to the stream. Writes a string and an array of bytes to the stream as additional data.

Serial Data:

The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
                        IOException

Deserializes this DragGestureEvent. This method first performs default deserialization for all non-transient fields. An attempt is then made to deserialize this object's List of gesture events as well. This is first attempted by deserializing the field events, because, in releases prior to 1.4, a non-transient field of this name stored the List of gesture events. If this fails, the next object in the stream is used instead. If the resulting List is null, this object's List of gesture events is set to an empty List.

Throws:

ClassNotFoundException

IOException

Since:

1.4

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Serializes this DragGestureEvent. Performs default serialization and then writes out this object's List of gesture events if and only if the List can be serialized. If not, null is written instead. In this case, a DragGestureEvent created from the resulting deserialized stream will contain an empty List of gesture events.

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
                        IOException

Deserializes this DragSource. This method first performs default deserialization. Next, this object's FlavorMap is deserialized by using the next object in the stream. If the resulting FlavorMap is null, this object's FlavorMap is set to the default FlavorMap for this thread's ClassLoader. Next, this object's listeners are deserialized by reading a null-terminated sequence of 0 or more key/value pairs from the stream:

• If a key object is a String equal to dragSourceListenerK, a DragSourceListener is deserialized using the corresponding value object and added to this DragSource.
• If a key object is a String equal to dragSourceMotionListenerK, a DragSourceMotionListener is deserialized using the corresponding value object and added to this DragSource.
• Otherwise, the key/value pair is skipped.

Serialization Overview

Class Class is special cased within the Serialization Stream Protocol. A Class instance is written initially into an ObjectOutputStream in the following format:

      TC_CLASS ClassDescriptor
      A ClassDescriptor is a special cased serialization of 
      a java.io.ObjectStreamClass instance. 
 

A new handle is generated for the initial time the class descriptor is written into the stream. Future references to the class descriptor are written as references to the initial class descriptor instance.
