Re: [pde-ui-dev] Understanding Product Editor Validation

[Brian Bauman <baumanbr@xxxxxxxxxx>]

The validating builders create an ErrorReporter
to report errors.  For example, the Manifest validation builder creates
a ManifestErrorReporter.  I believe all our ErrorReporters inherit
from XMLErrorReporter (I know most do).  This XMLErrorReporter class
contains a few "report" functions.  These function will
go through and place a marker on the file/resource being validated.  

From here, the Platform will handle
the UI rendering of the error/warning.  PDE never really triggers
the display, only creates an IMarker on the resource and the Platform takes
care of the rest.

Hope this helps

Subject	[pde-ui-dev] Understanding Product Editor Validation

Hello PDE-UI Team, 

I am currently developing an eclipse forms application. I need some input
validation like in the Product Editor. I looked at the code and I understand
most of it, but I can not find the lines where the Error/Warning messages
are created. 

As an example: 
In class WindowImagesSection
in method createClient()
all the inputs for different image file names are generated. Subclasses
of AbstractFormValidator
check their content. When there is no such file a error message is displayed.
But where is the code to display the message (it smoothly fades in just
where the page heading is, very nice ;-) ? I know how the String is constructed
but I can not find the graphical representation an the logic triggering
the display... 

I hope my question is not completely off-topic... 

Thank you, 

Martin _______________________________________________
