[news.eclipse.tools.gef] Re: Weird problem with ICellValidator

[Pavan Podila <pavan.podila@xxxxxxxxx>]

Hi Randy,
    That really helped. I found the problem was in the showCurrentEditValue() method of the DirectEditPolicy. I was directly picking up value from the CellEditor and showing it in the Editpart's figure. Obviously for invalid values, CellEditor.getValue() returns null, causing my label figure to become small. Cool, I guess making mistakes is the only way to understand GEF better!!!

A DirectEditPolicy will show feedback in the editpart's figure.  I'm not sure that anything different happens when isValid returns a message.  Also, see CellEditorManager to see how it responds to celleditor's firing value changed.  It should always do the same thing regarding feedback and sizing of the celleditor.

Thanks, that answers a part of my query. I still don't understand how the text of my label is getting set when I change the value inside the TextCellEditor. I haven't written any explicit code to do that. Can you tell me how that is happening.
I am using the schema editor code (Database schema editor article) and over there the label is getting resized irrespective of the validity of the string entered.

The label grows as you're typing because its text is set to what you're
entering in the TextCellEditor.  The answer to your query is in the javadoc
of CellEditor's getValue() method.  It will return null if the value is not
valid.

Hi,
    I have attached a CellValidator for the TextCellEditor of my label.
When I type my text in the TextCellEditor, the label size automatically
grows. However when the isValid() of the CellValidator returns a string
error message, the label size stops growing and resizes just big enough
to fit one character. I am attaching the screenshots below for the two
cases. What could be the problem?

thanks in advance,
Pavan
