Constructor Detail

BarRenderer

public BarRenderer(java.lang.String logconverterBase,
                   LAConverter[] logconverters,
                   java.awt.Color colorLow,
                   double thresholdLow,
                   double thresholdHigh,
                   java.awt.Color colorHigh)

Constructs a new renderer calculating on a percentage between the rendered converter and a base converter values. Renders a progress bar which width is based on the percentage calculated by computePercentage(Object, Object)
The color of the process bar is deduced from the following check :

• 0 <= percentage <= thresholdLow: the progress bar is painted with the colorLow color
• thresholdLow < percentage <= thresholdHigh: the progess bar is painted with a gradient form colorLow to colorHigh color
• thresholdHigh < percentage: the progress bar is painted with the colorHigh color

Parameters:

logconverterBase - Literal of the converter which value is the base of the percentage calculation.

logconverters - All the converters, the base converter must be one of them.

colorLow - Low color.

thresholdLow - If percentage <= thresholdErrorWarn the color used is colorLow.

thresholdHigh - If percentage > thresholdHigh the color used is colorHigh; otherwise is colorBase.

colorHigh - High color.

getTableCellRendererComponent

public java.awt.Component getTableCellRendererComponent(javax.swing.JTable table,
                                                        java.lang.Object value,
                                                        boolean isSelected,
                                                        boolean hasFocus,
                                                        int row,
                                                        int converter)

Sets text, height, borders and colors of the cell regarding to value, selection and focus.

Specified by:

getTableCellRendererComponent in interface javax.swing.table.TableCellRenderer

TableCellRenderer.getTableCellRendererComponent(javax.swing.JTable, java.lang.Object, boolean, boolean, int, int)

computePercentage

protected abstract double computePercentage(java.lang.Object value,
                                            java.lang.Object baseValue)

Calculates the percentage. Formula is specific and must be implemented by concrete class.

Parameters:

value - Rendered cell value.

baseValue - Base converter value.

Returns:

percentage Used to render the progress bar.

paintComponent

protected void paintComponent(java.awt.Graphics g)

Modification to the inherited behavior.
