AW: AW: [ve-dev] Overriding the Property-Editor in a Subclassdoes notseem to work

Hi
Rich!
if I
write
<event:Add
featureName="eStructuralFeatures">
<addedEObjects
xsi:type="ecore:EReference"
name="text"
eType="org.eclipse.jem.internal.java:JavaClass
java:/java.lang#String"
unsettable="true">
<eAnnotations
xsi:type="org.eclipse.ve.internal.cde.decorators:BasePropertyDecorator"
cellEditorClassname="RichDialogVisualEditor/ch.ivyteam.ivy.designer.richdialog.visualeditor.propertyeditor.RTextPropertyEditor"/>
</addedEObjects>
</event:Add>
then I
have
Warning 2006-06-22 09:48:12.122 Error loading

at

(error1.txt[Peter]
attachment)
if I
correct this to
<event:Add
featureName="eStructuralFeatures">
<addedEObjects
xsi:type="ecore:EReference"
name="text"
eType="org.eclipse.jem.java:JavaClass
java:/java.lang#String"

cellEditorClassname="RichDialogVisualEditor/ch.ivyteam.ivy.designer.richdialog.visualeditor.propertyeditor.RTextPropertyEditor"/>
</addedEObjects>
</event:Add>
then I don't have an error, but also not my
property editor for the text property.
If I do this (for an other property which was
nowhere defined in a superclass)
<event:Add
featureName="eStructuralFeatures">
<addedEObjects
xsi:type="ecore:EReference"
name="buttonText"
unsettable="true">
<eAnnotations
xsi:type="org.eclipse.ve.internal.cde.decorators:BasePropertyDecorator"
cellEditorClassname="RichDialogVisualEditor/ch.ivyteam.ivy.designer.richdialog.visualeditor.propertyeditor.RTextPropertyEditor"/>
</addedEObjects>
</event:Add>
I
have my editor for the buttonText property,
everything is fine.
So, whats wrong ?
Or do we have to think once again about my initial assumption that
this
is
just not possible with VE
?
Janak Mulani wrote to me "Eclipse VE's bean
handler requires that an attribute (a
structural feature) exists at one level only"
For me, this is an important restriction. Almost a deadly
one... Probably this has changed with VE 1.2
?
thanks & best
regards,
Peter
Hi,
You can do it through the
beaninfo, but if you don't have one it would be easier to do it through the
override file.
I wish you were at
1.2 because the format of the override file changes and I had to go back and
try to dig up the old format. :-)
I think this will do it:
<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:event="event.xmi"
xmlns:org.eclipse.ve.internal.cde.decorators="http:///org/eclipse/ve/internal/cde/decorators.ecore">
<event:Add

Hi Rich!
Thanks for the answer.
"You would have to
completely redefine the property at the RButton level. You would have to
completely specify it".
How could I redefine the property? How to
completely specify it?
Thru writing a custom BeanInfo class?
Thanks
& best regards,
Peter

Betreff: Re: [ve-dev] Overriding the

Hello,
There isn't really a safe
way to do that. You would have to completely
redefine the property at the
RButton level. You would have to completely
specify it.
As long as
the "text" property isn't a special property that some super
class may
access directly through the ULCButton's text estructuralfeature
it may
work. An example of an override that wouldn't work is to try to
change the
"components" feature of the awt Container. That is because this
is a very
special feature that is used directly and is not looked up by
name.
Because of that it would find the awt Component's feature. In your
case I
don't think this is true. Everywhere the feature is probably looked
up by
name and so it will find your feature first.

[ve-dev]
Overriding the Property-Editor in a Subclass does not seem to
work
Hi!
I'm currently writing a plugin
which customizes
the ULC VE plugin (own widgets, different
palette,
other property-editors, ...).
I'm struggling about the
following problem:
I have a class RButton which extends
ULCButton.
In my RButton.override I'd like to define an own
property
editor for the "text" property
(like in MyCustomPrompter.override from the
VE tutorial).
But this does not work.
Overriding of property
editors for properties which
already have defined a property editor
for
a property in a superclass generally
does not seem to be
possible.
If I make an own property like "buttonText", everything is
fine.
But this is only a workaround.
(I'm working with ULC VE 5.0
which bases on VE 1.1.0.1)
Any ideas, comments ?
Thanks
& best regards,
Peter
Koch
