Method Detail

installContext

public void installContext(JTable component,
                           Object value,
                           int row,
                           int column,
                           boolean selected,
                           boolean focused,
                           boolean expanded,
                           boolean leaf)

Sets state of the cell's context. Note that the component might be null to indicate a cell without a concrete context. All accessors must cope with.

Parameters:

component - the component the cell resides on, might be null

value - the content value of the cell

row - the cell's row index in view coordinates

column - the cell's column index in view coordinates

selected - the cell's selected state

focused - the cell's focused state

expanded - the cell's expanded state

leaf - the cell's leaf state

getComponent

public JTable getComponent()

Description copied from class: CellContext

Returns the component the cell resides on, may be null. Subclasses are expected to override and return the component type they are handling.

Overrides:

getComponent in class CellContext

Returns:

the component the cell resides on, may be null.

isEditable

public boolean isEditable()

Returns the cell's editable property as returned by table.isCellEditable or false if the table is null.

Overrides:

isEditable in class CellContext

Returns:

the cell's editable property.

getSelectionBackground

protected Color getSelectionBackground()

Returns the default selection background color of the renderered component. Typically, the color is LF specific. It's up to subclasses to look it up. Here: returns null.

PENDING: return UI properties here?

Overrides:

getSelectionBackground in class CellContext

Returns:

the selection background color of the rendered component.

getSelectionForeground

protected Color getSelectionForeground()

Returns the default selection foreground color of the renderered component. Typically, the color is LF specific. It's up to subclasses to look it up. Here: returns null.

PENDING: return UI properties here?

Overrides:

getSelectionForeground in class CellContext

Returns:

the selection foreground color of the rendered component.

getUIPrefix

protected String getUIPrefix()

Returns the component type specific prefix of keys for lookup in the UIManager. Subclasses must override, here: returns the empty String.

Overrides:

getUIPrefix in class CellContext

Returns:

the component type specific prefix.

isValidColumn

protected boolean isValidColumn()

PRE getComponent != null

Returns:

whether the column coordinate is valid in this context

isValidRow

protected boolean isValidRow()

PRE getComponent != null

Returns:

whether the row coordinate is valid in this context
