Constructor Detail

AccessibleJTableCell

public AccessibleJTableCell(JTable t, int r, int c, int i)

Creates a new AccessibleJTableCell.

Parameters: t the table r the row c the column i the index of this cell inside the accessible table parent

Method Detail

addFocusListener

public void addFocusListener(FocusListener listener)

Adds a focus listener to this cell. The focus listener is really added to the table, so there is no way to find out when an individual cell changes the focus.

Parameters: listener the focus listener to add

contains

public boolean contains(Point point)

Returns true if this table cell contains the location at point, false otherwise. point is interpreted as relative to the coordinate system of the table cell.

Returns: true if this table cell contains the location at point, false otherwise

getAccessibleAt

public Accessible getAccessibleAt(Point point)

Table cells have no children, so we return null here.

Returns: null

getAccessibleChild

public Accessible getAccessibleChild(int i)

Returns the accessible child at index i. Table cells don't have children, so we return null here.

Returns: null

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns the number of children of this object. Table cells cannot have children, so we return 0 here.

Returns: 0

getAccessibleContext

public AccessibleContext getAccessibleContext()

Returns the accessible context of this table cell. Since accessible table cells are their own accessible context, we return this.

Returns: the accessible context of this table cell

getAccessibleIndexInParent

public int getAccessibleIndexInParent()

Returns the index of this cell in the parent object.

Returns: the index of this cell in the parent object

getAccessibleRole

public AccessibleRole getAccessibleRole()

Returns the accessible row for the table cell.

Returns: the accessible row for the table cell

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Returns the accessible state set of this accessible table cell.

Returns: the accessible state set of this accessible table cell

getBackground

public Color getBackground()

Returns the background color of this cell.

Returns: the background color of this cell

getBounds

public Rectangle getBounds()

Returns the bounds of the cell relative to its table.

Returns: the bounds of the cell relative to its table

setBounds

public void setBounds(Rectangle rectangle)

The bounds of the table cells cannot be manipulated directly, so this method does nothing.

Parameters: rectangle not used

setCursor

public void setCursor(Cursor cursor)

Sets the cursor of the cell. Since table cells cannot have individual cursors, this method does nothing. Set the cursor directly on the table instead.

Parameters: cursor not used

Table cells cannot be disabled or enabled individually, so this method does nothing. Set the enabled flag on the table itself.

Parameters: b not used here

setFont

public void setFont(Font font)

Sets the font of the cell. Since table cells cannot have individual fonts, this method does nothing. Set the font directly on the table instead.

Sets the foreground of the cell. Since table cells cannot have individual foreground colors, this method does nothing. Set the foreground directly on the table instead.

Parameters: color not used

setLocation

public void setLocation(Point point)

The location of the table cells cannot be manipulated directly, so this method does nothing.

Parameters: point not used

setSize

public void setSize(Dimension dimension)

The size cannot be set on table cells directly, so this method does nothing.

Parameters: dimension not used

setVisible

public void setVisible(boolean b)

The visibility cannot be set on individual table cells, so this method does nothing. Set the visibility on the table itself.

Parameters: b not used
