Interface ConditionalFormatting

All Known Implementing Classes:
  HSSFConditionalFormatting, XSSFConditionalFormatting

    public interface ConditionalFormatting

The ConditionalFormatting class encapsulates all settings of Conditional Formatting. The class can be used

- to make a copy ConditionalFormatting settings.
For example:

     ConditionalFormatting cf = sheet.getConditionalFormattingAt(index);
     newSheet.addConditionalFormatting(cf);

- or to modify existing Conditional Formatting settings (formatting regions and/or rules).

Use `Sheet.getSheetConditionalFormatting()` to get access to an instance of this class.

To create a new Conditional Formatting set use the following approach:

     // Define a Conditional Formatting rule, which triggers formatting
     // when cell's value is greater or equal than 100.0 and
     // applies patternFormatting defined below.
     ConditionalFormattingRule rule = sheet.createConditionalFormattingRule(
         ComparisonOperator.GE,
         "100.0", // 1st formula
         null     // 2nd formula is not used for comparison operator GE
     );

     // Create pattern with red background
     PatternFormatting patternFmt = rule.cretePatternFormatting();
     patternFormatting.setFillBackgroundColor(IndexedColor.RED.getIndex());

     // Define a region containing first column
     Region [] regions =
     {
         new Region(1,(short)1,-1,(short)1)
     };

     // Apply Conditional Formatting rule defined above to the regions
     sheet.addConditionalFormatting(regions, rule);

Method Summary
`void` `addRule(ConditionalFormattingRule cfRule)` Add a Conditional Formatting rule.
`CellRangeAddress[]` `getFormattingRanges()`
`int` `getNumberOfRules()`
`ConditionalFormattingRule` `getRule(int idx)`
`void` `setRule(int idx, ConditionalFormattingRule cfRule)` Replaces an existing Conditional Formatting rule at position idx.

Method Detail

### getFormattingRanges

    CellRangeAddress[] getFormattingRanges()

  Returns:
    array of `CellRangeAddress`s. Never `null`

### setRule

    void setRule(int idx,
                 ConditionalFormattingRule cfRule)

  Replaces an existing Conditional Formatting rule at position idx. Excel allows to create up to 3 Conditional Formatting rules. This method can be useful to modify existing Conditional Formatting rules.

  Parameters:
    `idx` - position of the rule. Should be between 0 and 2.
    `cfRule` - - Conditional Formatting rule

### addRule

    void addRule(ConditionalFormattingRule cfRule)

  Add a Conditional Formatting rule. Excel allows to create up to 3 Conditional Formatting rules.

  Parameters:
    `cfRule` - - Conditional Formatting rule

### getRule

    ConditionalFormattingRule getRule(int idx)

  Returns:
    the Conditional Formatting rule at position idx.

### getNumberOfRules

    int getNumberOfRules()

  Returns:
    number of Conditional Formatting rules.
