installContext
public void installContext(javax.swing.JTable component, java.lang.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 nullvalue
- the content value of the cellrow
- the cell's row index in view coordinatescolumn
- the cell's column index in view coordinatesselected
- the cell's selected statefocused
- the cell's focused stateexpanded
- the cell's expanded stateleaf
- the cell's leaf state
-
getComponent
public javax.swing.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 classCellContext
- 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 classCellContext
- Returns:
- the cell's editable property.
-
getBackground
protected java.awt.Color getBackground()
Description copied from class:CellContext
Returns the background color of the renderered component or null if the component is nullPENDING: fallback to UI properties if comp == null?
- Overrides:
getBackground
in classCellContext
- Returns:
- the background color of the rendered component.
-
getAlternateRowColor
protected java.awt.Color getAlternateRowColor()
Returns a Color to for odd row background if this context should handle the alternating row color AND the UIManager has the alternateRowColor property set. Returns null otherwise.- Returns:
- the color to use for odd row background, or null if either this context does not handle or no alternate row color is set.
-
getSelectionBackground
protected java.awt.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 classCellContext
- Returns:
- the selection background color of the rendered component.
-
getSelectionForeground
protected java.awt.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 classCellContext
- Returns:
- the selection foreground color of the rendered component.
-
getUIPrefix
protected java.lang.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 classCellContext
- 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
