RE: hssf poi conditional formatting.

RDI will make java prototypes. But knowing how to use them is what was getting me. Of course I forgot to bookmark a good simple java sample page of the steps to do it.

Maybe this has some potential to be a GitHub project, or two. The second being a project that creates RPG prototypes from a Java Package.

I've done it, I just have to dig up where. Some caveats first, I am using POI v3.14. POI v3.15 has refactored some of the constants into Enums, so if you go there you may need to do some refactoring to get everything working again. I haven't tested that theory yet.

Here are some prototypes I added to Scotts file to accomplish this:

dcl-c CELLRANGEADDRESS_CLASS
'org.apache.poi.ss.util.CellRangeAddress';
dcl-c CONDITIONALFORMATTINGRULE_CLASS
'org.apache.poi.ss.usermodel.ConditionalFormattingRule';
dcl-c FONTFORMATTING_CLASS
'org.apache.poi.ss.usermodel.FontFormatting';
dcl-c PATTERNFORMATTING_CLASS
'org.apache.poi.ss.usermodel.PatternFormatting';
dcl-c SHEETCONDITIONALFORMATTING_CLASS
'org.apache.poi.ss.usermodel.SheetConditionalFormatting';

dcl-s CellRangeAddress Object(*JAVA: CELLRANGEADDRESS_CLASS);
dcl-s ConditionalFormattingRule
Object(*JAVA: CONDITIONALFORMATTINGRULE_CLASS);
dcl-s FontFormatting Object(*JAVA: FONTFORMATTING_CLASS);
dcl-s PatternFormatting Object(*JAVA: PATTERNFORMATTING_CLASS);
dcl-s SheetConditionalFormatting
Object(*JAVA: SHEETCONDITIONALFORMATTING_CLASS);

Be careful though, there is some inconsistency between style fills and conditional formatting fills. In a style, the Solid Fill uses the Foreground color to give the cell a solid background. I believe that in conditional formatting, the solid fill uses the background color to give the cell a solid background, but for the rest of the fill patterns, the foreground and background colors do the same thing as they do for the cell style. I believe this is a strangeness attributable to Excel rather than POI. If it doesn't do what you expected, you may have to tinker with the foregraund and background colors for the fill.

Subject: hssf poi conditional formatting.


Does anyone have sample of using conditional formatting in RPG when building a spreadsheet using HSSF POI? I am trying to work thru a java sample and converting it to RPGLE using RDI java method call prototype creator, but it is a slow painful process so far. I thought I would check to see if any already created this particular wheel.

I have a sheet with calculations. If the value is negative make it red and bold. Sounds easy I thought.
Thanks for any help.
