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.

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:

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.

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.

Deserializes this DragGestureRecognizer. This method first performs default deserialization for all non-transient fields. This object's DragGestureListener is then deserialized as well by using the next object in the stream.

Throws:

ClassNotFoundException

IOException

Since:

1.4

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Serializes this DragGestureRecognizer. This method first performs default serialization. Then, this object's DragGestureListener is written out if and only if it can be serialized. If not, null is written instead.

Serial Data:

The default serializable fields, in alphabetical order, followed by either a DragGestureListener, or null.

Throws:

IOException

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.

Throws:

ClassNotFoundException

IOException

Since:

1.4

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Serializes this DragSource. This method first performs default serialization. Next, it writes out this object's FlavorMap if and only if it can be serialized. If not, null is written instead. Next, it writes out Serializable listeners registered with this object. Listeners are written in a null-terminated sequence of 0 or more pairs. The pair consists of a String and an Object; the String indicates the type of the Object and is one of the following:

• dragSourceListenerK indicating a DragSourceListener object;
• dragSourceMotionListenerK indicating a DragSourceMotionListener object.

Serial Data:

Either a FlavorMap instance, or null, followed by a null-terminated sequence of 0 or more pairs; the pair consists of a String and an Object; the String indicates the type of the Object and is one of the following:

• dragSourceListenerK indicating a DragSourceListener object;
• dragSourceMotionListenerK indicating a DragSourceMotionListener object.

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
                        IOException

Deserializes this DragSourceContext. This method first performs default deserialization for all non-transient fields. This object's Transferable and DragSourceListener are then deserialized as well by using the next two objects in the stream. If the resulting Transferable is null, this object's Transferable is set to a dummy Transferable which supports no DataFlavors.

Throws:

ClassNotFoundException

IOException

Since:

1.4

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Serializes this DragSourceContext. This method first performs default serialization. Next, this object's Transferable is written out if and only if it can be serialized. If not, null is written instead. In this case, a DragSourceContext created from the resulting deserialized stream will contain a dummy Transferable which supports no DataFlavors. Finally, this object's DragSourceListener is written out if and only if it can be serialized. If not, null is written instead.

Serial Data:

The default serializable fields, in alphabetical order, followed by either a Transferable instance, or null, followed by either a DragSourceListener instance, or null.

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
                        IOException

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

Throws:

ClassNotFoundException
