RE: [birt-dev] API change request
+1 for removing the report/module level unit setting in BIRT report designer UI. 
 
If we are going to remove the default unit from module handle in model, shall we also remove it from the session handle?  Since both unit properties will not apply to all element sizes, such as width and font can not share the same unit.

Yes, BIRT report designer explicitly set the units whenever it set the value for a report element’s dimension property.

 

If others develop a custom report designer that does not set the unit, the default unit of this element defined in ROM will take effect. If it is not defined in ROM, then the one setting on session handle will take effect. Otherwise, a semantic warning will be thrown. (A dimension value without unit may cause failure when engine render the report in html and pdf)

 

If we remove this property from module, then user can not set general units for a single module any more, he/she could just set the units on session, or on individual design element.

Even now, the general unit is not always suitable for all kinds of elements, for example, if user set unit to be “mm”, but “mm” is not a common unit for font size. So ROM defines some default units for those that suppose to have their own default value. The default unit search route is:

 

ROM

Module

Session

 

 

The bug reporter thinks there should be a switch to decide either to use the metric system or the US/English system. But the unit he/she setting on module does not take effect since BIRT report designer has explicitly set units for elements. To avoid confusion, Qiangsheng suggests deprecating this property.

Does BIRT report designer explicitly set the units whenever it set the value for a report elements' size property?

 

Can others develop a custom report designer that does not set the unit?  In such a usage, is report level "unit" property useful? 

 

thanks

There is a bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=174259, General settings for "Units" is ignored.
Since the Designer will decide the default units for each kind of element and it takes higher priority, the one user setting on the report looks ignored.
Now propose to remove the ‘unit’ property from ReportDesign in ROM, and corresponding API, to avoid confusion.
