Understanding Product Editor Validation

Rate this Message:
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 _______________________________________________ pde-ui-dev mailing list pde-ui-dev@... https://dev.eclipse.org/mailman/listinfo/pde-ui-dev |

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.

Hello Martin,
Take a look at IEditorValidationStack#top() and its implementation in EditorValidationStack#top() The actual call that you are probably looking for (that slides up the message) is Form#setMessage(String message, int Severity) where Form is retreived from an IFormPage (see EditorValidationStack#getForm(IEditorValidator validator) for an example) Good luck and feel free to post any follow ups, P.S If you follow the code we use in PDE (see PDEFormEditor for IEditorValidationStack and use FormEntry objects for your fields) you shouldn't have to call setMessage yourself as it will be called automatically if your FormEntrys are set with IEditorValidators.

Janek,
This is all great stuff and certainly applicable to anyone doing forms validation in the RCP. Is there any chance that these classes might be factored out into a "lighter weight" plugin so that we don't have to include the entire PDE just to get forms validation? Alternatively, could they be folded into one of the other, lower-level UI plugins? Thanks. graham -- Marketcetera Trading Platform download.run.trade. www.marketcetera.org
