Class TabSet

java.lang.Object

javax.swing.text.TabSet

All Implemented Interfaces:

Serializable

public class TabSet
extends Object
implements Serializable

A TabSet is comprised of many TabStops. It offers methods for locating the closest TabStop to a given position and finding all the potential TabStops. It is also immutable.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

getTabCount

public int getTabCount()

Returns the number of Tab instances the receiver contains.

Returns:

the number of Tab instances the receiver contains

getTab

public TabStop getTab(int index)

Returns the TabStop at index index. This will throw an IllegalArgumentException if index is outside the range of tabs.

Parameters:

index - which TapStop to return

Returns:

the TabStop at index index

getTabAfter

public TabStop getTabAfter(float location)

Returns the Tab instance after location. This will return null if there are no tabs after location.

Parameters:

location - location to find a Tab after

Returns:

the Tab instance after location

getTabIndex

public int getTabIndex(TabStop tab)

Returns the index of the TabStop tab, or -1 if tab is not contained in the receiver.

Parameters:

tab - the TabStop to find

Returns:

the index of the TabStop tab, or -1 if tab is not contained in the receiver.

getTabIndexAfter

public int getTabIndexAfter(float location)

the index of the Tab to be used after location

equals

public boolean equals(Object o)

Indicates whether this TabSet is equal to another one.

Overrides:

equals in class Object

Parameters:

o - the TabSet instance which this instance should be compared to.

Returns:

true if o is the instance of TabSet, has the same number of TabStops and they are all equal, false otherwise.
