javax.swing.table.DefaultTableCellRenderer — clojure-interop/javax.swing 1.0.5

The standard class for rendering (displaying) individual cells in a JTable.

Implementation Note: This class inherits from JLabel, a standard component class. However JTable employs a unique mechanism for rendering its cells and therefore requires some slightly modified behavior from its cell renderer. The table class defines a single cell renderer and uses it as a as a rubber-stamp for rendering all cells in the table; it renders the first cell, changes the contents of that cell renderer, shifts the origin to the new location, re-draws it, and so on. The standard JLabel component was not designed to be used this way and we want to avoid triggering a revalidate each time the cell is drawn. This would greatly decrease performance because the revalidate message would be passed up the hierarchy of the container to determine whether any other components would be affected. As the renderer is only parented for the lifetime of a painting operation we similarly want to avoid the overhead associated with walking the hierarchy for painting operations. So this class overrides the validate, invalidate, revalidate, repaint, and firePropertyChange methods to be no-ops and override the isOpaque method solely to improve performance. If you write your own renderer, please keep this performance consideration in mind.

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.

->default-table-cell-renderer clj

(->default-table-cell-renderer)

Constructor.

Creates a default table cell renderer.

fire-property-change clj

(fire-property-change this property-name old-value new-value)

Overridden for performance reasons. See the Implementation Note for more information.

property-name - the property whose value has changed - java.lang.String old-value - the property's previous value - boolean new-value - the property's new value - boolean

get-table-cell-renderer-component clj

(get-table-cell-renderer-component this
                                   table
                                   value
                                   is-selected
                                   has-focus
                                   row
                                   column)

Returns the default table cell renderer.

During a printing operation, this method will be called with isSelected and hasFocus values of false to prevent selection and focus from appearing in the printed output. To do other customization based on whether or not the table is being printed, check the return value from JComponent.isPaintingForPrint().

table - the JTable - javax.swing.JTable value - the value to assign to the cell at [row, column] - java.lang.Object is-selected - true if cell is selected - boolean has-focus - true if cell has focus - boolean row - the row of the cell to render - int column - the column of the cell to render - int

returns: the default table cell renderer - java.awt.Component

invalidate clj

(invalidate this)

Overridden for performance reasons. See the Implementation Note for more information.

opaque? clj

(opaque? this)

Overridden for performance reasons. See the Implementation Note for more information.

returns: true if this component is completely opaque - boolean

repaint clj

(repaint this)

(repaint this r)

(repaint this tm x y width height)

Overridden for performance reasons. See the Implementation Note for more information.

tm - this parameter is not used - long x - the x value of the dirty region - int y - the y value of the dirty region - int width - the width of the dirty region - int height - the height of the dirty region - int

revalidate clj

(revalidate this)

Overridden for performance reasons. See the Implementation Note for more information.

set-background clj

(set-background this c)

Overrides JComponent.setBackground to assign the unselected-background color to the specified color.

c - set the background color to this value - java.awt.Color

set-foreground clj

(set-foreground this c)

Overrides JComponent.setForeground to assign the unselected-foreground color to the specified color.

c - set the foreground color to this value - java.awt.Color

update-ui clj

(update-ui this)

Notification from the UIManager that the look and feel [L&F] has changed. Replaces the current UI object with the latest version from the UIManager.

validate clj

(validate this)

Overridden for performance reasons. See the Implementation Note for more information.
