Hi,
I would like to utilize BIRT APIs. Is there a document which lists the APIs and what they do? I am looking for APIs to remove columns and rows, change text color, change font and preview mainly; however, might need more later.
please advise
Neil

Neil,
If you just want to drop a detail row you can use the drop method. I am
attaching a test class that shows how to do various things with the de
api. In the example I insert a detail row using the
RowOperationParameters class. Right before I save the design I drop the
added row.

Neil,
1 - If you just want to set the color do
tableheader.setProperty(StyleHandle.BACKGROUND_COLOR_PROP, "Blue");
or
tableheader.setProperty(StyleHandle.BACKGROUND_COLOR_PROP, "#FF8080");
2 - Not sure what you want here. Are you needing the fontFamily changed
use:
tableheader.setProperty( StyleHandle.FONT_WEIGHT_PROP,
DesignChoiceConstants.FONT_WEIGHT_BOLD );
tableheader.setProperty( StyleHandle.FONT_FAMILY_PROP, "Century" );
tableheader.setProperty( StyleHandle.FONT_SIZE_PROP, "12pt" );
3 - Do you mean row height or font size?
tableheader.setProperty(ReportItemHandle.HEIGHT_PROP, "1.2in");
4 - What is the context? The Web Viewer is a plugin and you can call
the WebViewer.display method from a RCP/Eclipse based app.

Neil,
I believe this will depend on what fonts are installed on your system.
The viewer plugin is org.eclipse.birt.report.viewer.

Neil,
Can you try something like:
BrowserManager bmg = BrowserManager.getInstance();
bmg.setAlwaysUseExternal(false);
HashMap myparms = new HashMap();
HashMap emitmap = new HashMap();
myparms.put("SERVLET_NAME_KEY", "frameset");
myparms.put("FORMAT_KEY", "html");
//myparms.put("RESOURCE_FOLDER_KEY", "c:/myresources");
myparms.put("ALLOW_PAGE", "false");
myparms.put("SHOW_PARAMETER_PAGE", "false");
//emitmap.put("Top Count", "6");
//myparms.put("EMITTER_OPTIONS_KEY", emitmap);
//myparms.put("MAX_ROWS_KEY", "500");
//WebViewer.display(rpt, browser, myparms);
//WebViewer.display(reportName, browser, myparms);
WebViewer.display(reportName, myparms);
I have commented out some of the options.

Neil,
Use MAX_ROWS_KEY:
HashMap myparms = new HashMap();
HashMap emitmap = new HashMap();
myparms.put("SERVLET_NAME_KEY", "frameset");
myparms.put("FORMAT_KEY", "html");
myparms.put("SHOW_PARAMETER_PAGE", "false");
myparms.put(WebViewer.MAX_ROWS_KEY, "5");
WebViewer.display(reportName, browser, myparms);
