Reference Documentation

edited May 2009 in RAP
Hi,

where can I find some reference documentation about Rap types?
Sometimes I need to know which properties or methods are exported by a type,
but I don't know where to find these informations.

Thank you in advance.

    The The ReportBuilder RAP reference is installed with ReportBuilder and
    integrated in to the Delphi help system.

    The RAP Code Toolbox at the bottom right corner of the Calc workspace has an
    Objects and Language tab that are a good quick reference.

    By default RAP knows about published properties of classes registered with
    Delphi's RTTI system. RAP has an extended RTTI system built on top of
    Delphi's. The RAP reference and tutorials detail how to extend RAP with
    custom RTTI and csutom functions.

    In "The ReportBuilder RAP reference" I cannot find that TppDataPipeline has
    "FieldObjects" and "NoRecords" properties.
    These are two examples of usefull elements that I cannot find neither in the
    documentation nor in RAP Code Toolbox.

    Thank you in advance.

    1. To access a field value, use myDataPipeline['FieldName'] - this code is
    generated for you if you drag a field from the Code Toolbox to the designer.

    2. To access the TppField objects, use
    myDataPipeline.FieldObjects['FieldName'], here is an example on rbWiki that
    shows how to check whether a field is null.

    3. To check whether a DataPipeline has records, use the Bof and Eof
    properties

    lbHasNoData := myDataPipeline.Bof and myDataPipeline.Eof;


    4. Here is a list of additional RAP references

    1. The ReportBuilder Developers Guide includes conceptual and tutorial info.

    2. There are RAP demos and tutorials installed with the product.

    3. rbWiki contains additional articles and "How To's"

    http://www.digital-metaphors.com/rbWiki/RAP

    4. The RAP newsgroups :)

    Thank you for your answer, but these were only two examples...
    I think that a complete reference should be a lot better.
    I can look in source code too (in Tra....RTTI classes), but all these
    solutions are not productive as using a complete reference guide and having
    the code completion feature in the code editor.
    Please consider these two requirements for future releases.

    Thank you in advance.
