[news.eclipse.birt] Re: How can I set a CSS class name for a report item

[Jason Weathersby <jasonweathersby@xxxxxxxxxx>]

Guenter,

Can you first try the "use CSS File" option for a blank report.  This is 
available in the right context of the styles node in the outline view. 
In the filename specify a css file with the same names that can be used 
in the designer and check the include CSS file at view time and specify 
the url to the CSS you wish to use at view time.  If you use this 
method, in the designer BIRT will generate styles like:

In the designer:
		<style type="text/css">
				.style_report { font-family: serif; font-style: normal; 
font-variant: normal; font-weight: normal; font-size: medium; color: 
black; text-indent: 0em; letter-spacing: normal; word-spacing: normal; 
text-transform: none; white-space: normal; line-height: normal; 
direction: ltr;}
				.style_2 { font-family: Arial; font-weight: bold; font-size: 
x-small; color: rgb(0, 0, 0); padding: 0px; background-color: rgb(230, 
236, 255);}
		</style>
		<link rel="stylesheet" type="text/css" 
href="styles/LinksPastelBlue.css"></link>

and the item will have classnames like:
<tr class="style_1 myspecial-header" valign="top">

when the report is deployed to an appserver it will produce only this 
for your referenced styles:

		<link rel="stylesheet" type="text/css" 
href="styles/LinksPastelBlue.css"></link>

and the same table row as above will look like:
<tr class="myspecial-header" valign="top">


So you can see in the designer it creates the style (ie style_2) but 
also includes the link to the external style sheet.  The actual 
reference to a style will then have both style names and should default 
to the external style sheet.

In the app server only the external style sheet is used.

I am not certain this answered your question though.
