Changing report font dynamically (Java)

[pheynman]

Hi,

I was wondering if anybody had had to change report fonts dynamically depending on what the user would like to use. Does it depend on the report definition being defined to accept variables like:

[COLOR=blue]If[/color] {?NewFont} <> [COLOR=red]""[/color] [COLOR=blue]Then[/color]
    {?NewFont}
[COLOR=blue]Else[/color]
    [COLOR=blue]DefaultAttribute[/color]

or can you just wrire code against it and call the crystal report viewer?

This is what I have (briefly):

	[COLOR=purple]private void[/color] ChangeFont(IEnterpriseSession enterpriseSession, IInfoObject report) [COLOR=purple]throws[/color] SDKException, ReportSDKException
	{
		IReportAppFactory reportFactory = (IReportAppFactory) enterpriseSession.getService("RASReportFactory");
		ReportClientDocument reportClientDocument = reportFactory.openDocument(report, 0, Locale.getDefault());
		ReportObjectController reportObjectController = reportClientDocument.getReportDefController().getReportObjectController();
		ReportObjects reportObjects = reportObjectController.getReportObjectsByKind(ReportObjectKind.text);

		IFontColor newFontColor = getFontColor();

		[COLOR=purple]if[/color] (reportObjects != [COLOR=purple]null[/color] && !reportObjects.isEmpty())
		{
			[COLOR=purple]for[/color] ([COLOR=purple]int[/color] i = 0; i < reportObjects.size(); i++)
			{
				IReportObject reportObject = reportObjects.getReportObject(i);
				[COLOR=purple]if[/color] (reportObject instanceof ITextObject)
				{
					ITextObject textObject = (ITextObject) reportObject;
					IFontColor fontColor = textObject.getFontColor();
					fontColor = newFontColor;
					textObject.setFontColor(fontColor);					
				}
			}
		}
		
		reportObjects = reportObjectController.getReportObjectsByKind(ReportObjectKind.field);

		[COLOR=purple]if[/color] (reportObjects != [COLOR=purple]null[/color] && !reportObjects.isEmpty())
		{
			[COLOR=purple]for[/color] ([COLOR=purple]int[/color] i = 0; i < reportObjects.size(); i++)
			{
				IReportObject reportObject = reportObjects.getReportObject(i);
				[COLOR=purple]if[/color] (reportObject [COLOR=purple]instanceof[/color] IFieldObject)
				{
					IFieldObject fieldObject = (IFieldObject) reportObject;	
					IFontColor fontColor = fieldObject.getFontColor();
					fontColor = newFontColor;
					fieldObject.setFontColor(fontColor);
				}
			}
		}
	}

There may be a lot wrong with the code but for now, I'm focusing on the stuff that could enable the changes. I tried this code with the way the viewer is currently set up. This viewer is custom; not the com.crystaldecisions.report.web.viewer.CrystalReportViewer which is what I'm now trying to use (and have not finished coding):

com.crystaldecisions.report.web.viewer.CrystalReportViewer vwr = new com.crystaldecisions.report.web.viewer.CrystalReportViewer();
vwr.processHttpRequest(_request, _response, getServletContext(), [COLOR=purple]null[/color]);
vwr.setHasExportButton(true);
vwr.setDisplayGroupTree(true);
vwr.setReportSource(report);
vwr.setDisplayPage(true);

Any help in the right direction (beyond just a link to the SDKs which I'm working through) would be appreciated.

Thanks.
