Class HSSFConditionalFormatting

java.lang.Object

org.zkoss.poi.hssf.usermodel.HSSFConditionalFormatting

All Implemented Interfaces:

ConditionalFormatting

public final class HSSFConditionalFormatting
extends java.lang.Object
implements ConditionalFormatting

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

• to make a copy HSSFConditionalFormatting settings.
For example:

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

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

Use HSSFSheet.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.
 HSSFConditionalFormattingRule rule = sheet.createConditionalFormattingRule(
     ComparisonOperator.GE, 
     "100.0", // 1st formula 
     null     // 2nd formula is not used for comparison operator GE
 );
 
 // Create pattern with red background
 HSSFPatternFormatting patternFmt = rule.cretePatternFormatting();
 patternFormatting.setFillBackgroundColor(HSSFColor.RED.index);
 
 // 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);
