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

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.

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!!!

<tt>Hi Randy,<br>
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!!!<br>

<tt>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.<br>
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.</tt><br>

<pre wrap="">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.

<pre wrap="">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
