[OpendTect_Developers] service functions and macros to make attribute implementation easier

[Hélène Huck]

Hi all,

When it comes to plugin development to OpendTect, one of our main goals 
is to try as much as possible to facilitate your work.
This is certainly true for those of you who would want to code their own 
Attributes: it should be as quick and easy as possible so that you can 
rather focus on your algorithm.

Let's take a quick example to illustrate this:
/BufferString        zDepLabel(const char* pre,const char* post) const/
  is a small service function which allows you to add, in the user 
interface of your attribute,  a field for a parameter in the Z direction 
without having to bother coding yourself for all the possibilities 
(survey in time/depth, which units...)
I write in the code:
/zDepLabel("Maximum","shift")        [to be found in 
/uiAttributes/uiattrdesced.h]/

and depending on the survey settings the user will see "maximum time 
shift (ms)" or maybe "maximum depth shift (ft)", quick and easy, your 
interface is correct with very little effort.

There are lots of other service functions and macros designed to make 
your coding life easy (for instance in /AttributeEngine/attribdesc.h and 
/uiAttributes/paramsetget.h); at least those we thought of! Should you 
think of another function or macro missing which would be profitable for 
everyone implementing an attribute plugin, please do not hesitate to 
reply to this email!

Best regards,
Hélène
