You can use the DE API to add a label to a report, but where do you want to call it from?

Hello Jason,

Glad to hear from you.

I know how to add a label programatically using DE API. What I really need is a report item that can not be changed in rcp designer, e.g. , I add a label (programatically) to the report that has blank background and black characters. I don't want end users that will design the remaning report layout to be able to change that label. Made myself clear?....

I will problably need to create a custom item due to other characteristics, this would solve my problem?

Thank you
Teresa

That is a tough one. Even if you create a custom report item, they could always open up the xml and change values.

Hello Jason,

Yes, that is a good point and I had already thought about that but my end users probably don't know how to change the xml, not being able to change in designer would be a first blocker... But if it is not possible at all tell me and I will try to think of another solution ...

Thank you

I think you could use the report item extensions to prevent the label from being edited, but I do not think you can prevent them from deleting it. This would make a good enhancement request if you want to log it in bugzilla.

Hello Jason,

Just to keep you updated:

I have created a custom item that outputs as a preformated HTML so there is no way my end-users can change its presentation, which is the most important for me. The contents come from data source so I will have no problem with that also.

Regarding to deleting I will have to validate at runtime if the item was removed.

I've followed de RotatedText sample, the only thing I couldn't achieve is WYSIWYG because I didn't find a provider for Html. Do I have to do it as an image?....

Thank you!!

JasonW

If you look at the getOutputType method in that example it is set to image you should be able to use:
OUTPUT_AS_HTML_TEXT
And then return a String containing the HTML in the onRowSets method.

Yes, I've done that successfully to achieve "WhatYouGet" but "WhatYouSee" is in the example as an image, using IReportItemImageProvider instead of IReportItemLabelProvider. What should I use to "see" in the designer what I "get" in preview ?... 
 
On "onRowSets" I am returning something like 
 
"<div>"+ text +" </div>";

JasonW

In the plugin.xml remove:
<reportItemFigureUI
class="org.eclipse.birt.sample.reportitem.rotatedtext.RotatedTextFigureUI">
</reportItemFigureUI>
and add this:
<reportItemLabelUI
class="org.eclipse.birt.sample.reportitem.rotatedtext.RotatedTextLabelUI">
</reportItemLabelUI>
This will just use the text. If you do not like this approach and you want to keep it as a figure modify RotatedTextFigure to draw text instead of an image.

Yes, that's what I have now but it only returns text, html formatting is not possible.

It's not a big question for now, only wanted to know if there was a simple way to do it.

Thank you for your help and atention.

JasonW

Right now the extension only supports figures, labels and images I believe.
