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 CellRangeAddresss. 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.
