Probably the best you will get is pointers to existing source code (Eric
Gamma's monkey-see-monkey-do principle) and it will typically be quite
complex. The XSDEditor is a relatively simple (i.e., crude) example.
It will reparse the text whenever the text changes. It uses an
IDocumentListener with a delay to avoid responding to every key stroke.
For the reverse, the command stack listener calls
handleStructuredModelChange whenever a command has been executed, which
serializes the resource in memory and updates the text in the text
editor. This is quite a brute force approach, but should serve as a
starting point.

Ed,
Thats right ! thats y i sought to see the PDE Editor , but for my
requirement its quite complex hence i asked for somthing much simpler.
Will try the XSD editor.
Thanks .

Doesn't WTP have an XML editor? I don't use it but I'd expect that they
have text/model sync...

would be an extremely cool combination. A generated EMF editor with a
source view would be possible...

Indeed. But personally I'd prefer to see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=108470 addressed before ;-)

Ed and Eike,
Thanks for further Information . Actually i thoght of looking in to that
.. Let me do it . If am successfull i shall contribue a patch to EMF
editor generation to have an Text editor that will edit the source .
Thanks for the info .

Ed and Eike,
The WTP SED is cool one . We have something called the
StrucutredTextEditor , we can use that i guess. I am just looking in to
that option , once am successful i shall post the message.
Thanks.

Ed and Eike,
I am able to successully integrate the WTP SED with my Editor . Lots of
redundant stuff has been removed from the common TextEditor that we
develop. But am facing a peculiar problem with the same , whenever we
want to fire the PROP_DIRTY with StructuredTextEditor(WTP Text Editor)
we need to implement the Property Change listener and register the same
with WTP SED , when i do a == comparison between the source and my
initialised text editor inside my propertyChanged(Object source, int
propId) is failing , though when i print the same in the console its
same object name
/*
* (non-Javadoc)
*
* @see
org.eclipse.ui.IPropertyListener#propertyChanged(java.lang.O bject,
* int)
*/
public void propertyChanged(Object source, int propId) {
System.out.println("Source : " + source + " propID :" + propId
+ "PROP_Dirty=" + IEditorPart.PROP_DIRTY);
System.out.println("Source Editor :" + sourceEditor);
switch (propId) {
case IEditorPart.PROP_DIRTY:
case IEditorPart.PROP_INPUT: {
if (source == sourceEditor) {
if (sourceEditor.getEditorInput() != getEditorInput()) {
System.out.println("2.1");
setInput(sourceEditor.getEditorInput());
Runnable runnable = new Runnable() {
public void run() {
firePropertyChange(IEditorPart.PROP_DIRTY);
}
};
postOnDisplayQue(runnable);
}
}
break;
}
}
}
Can you help me why its failing ??

I know it has been over a year since the last post on this topic, but,
any updates on this? As of now, the generated EMF multipage editor still

Thanks,

David,
Trying to usurp EMFT contributors are you?! :-P
It would be very helpful for WTP to provide SSE in a form that's more
easily consumable (i.e., with minimal dependencies).
https://bugs.eclipse.org/bugs/show_bug.cgi?id=205892
I suspect that would require some fundamental restructuring that would
break APIs, so that's not so likely to happen even with contributor
involvement...

Kamesh,
Probably the best you will get is pointers to existing source code (Eric
Gamma's monkey-see-monkey-do principle) and it will typically be quite
complex. The XSDEditor is a relatively simple (i.e., crude) example.
It will reparse the text whenever the text changes. It uses an
IDocumentListener with a delay to avoid responding to every key stroke.
For the reverse, the command stack listener calls
handleStructuredModelChange whenever a command has been executed, which
serializes the resource in memory and updates the text in the text
editor. This is quite a brute force approach, but should serve as a
starting point.

Ed,
Thats right ! thats y i sought to see the PDE Editor , but for my
requirement its quite complex hence i asked for somthing much simpler.
Will try the XSD editor.
Thanks .

Doesn't WTP have an XML editor? I don't use it but I'd expect that they
have text/model sync...

Eike,
Yes, WTP has a very cool SED DOM that incrementally synchronizes a DOM
structure with the textual source view of it. This in combination with
something that incrementally synchronizes an EMF model with that DOM
would be an extremely cool combination. A generated EMF editor with a
source view would be possible...

Indeed. But personally I'd prefer to see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=108470 addressed before ;-)

Ed and Eike,
Thanks for further Information . Actually i thoght of looking in to that
.. Let me do it . If am successfull i shall contribue a patch to EMF
editor generation to have an Text editor that will edit the source .
Thanks for the info .

Ed and Eike,
The WTP SED is cool one . We have something called the
StrucutredTextEditor , we can use that i guess. I am just looking in to
that option , once am successful i shall post the message.
Thanks.

Ed and Eike,
I am able to successully integrate the WTP SED with my Editor . Lots of
redundant stuff has been removed from the common TextEditor that we
develop. But am facing a peculiar problem with the same , whenever we
want to fire the PROP_DIRTY with StructuredTextEditor(WTP Text Editor)
we need to implement the Property Change listener and register the same
with WTP SED , when i do a == comparison between the source and my
initialised text editor inside my propertyChanged(Object source, int
propId) is failing , though when i print the same in the console its
same object name
/*
* (non-Javadoc)
*
* @see
org.eclipse.ui.IPropertyListener#propertyChanged(java.lang.O bject,
* int)
*/
public void propertyChanged(Object source, int propId) {
System.out.println("Source : " + source + " propID :" + propId
+ "PROP_Dirty=" + IEditorPart.PROP_DIRTY);
System.out.println("Source Editor :" + sourceEditor);
switch (propId) {
case IEditorPart.PROP_DIRTY:
case IEditorPart.PROP_INPUT: {
if (source == sourceEditor) {
if (sourceEditor.getEditorInput() != getEditorInput()) {
System.out.println("2.1");
setInput(sourceEditor.getEditorInput());
Runnable runnable = new Runnable() {
public void run() {
firePropertyChange(IEditorPart.PROP_DIRTY);
}
};
postOnDisplayQue(runnable);
}
}
break;
}
}
}
Can you help me why its failing ??

Kamesh, Ed,
I know it has been over a year since the last post on this topic, but,
any updates on this? As of now, the generated EMF multipage editor still
lacks a source editor.
Thanks,
Vasanth

Vasanth,
It's highly unlikely that that without active contributors from the
community this issue will get addressed directly by the vanishingly
small EMF team. It would make a great EMFT component.

David,
Trying to usurp EMFT contributors are you?! :-P
It would be very helpful for WTP to provide SSE in a form that's more
easily consumable (i.e., with minimal dependencies).
https://bugs.eclipse.org/bugs/show_bug.cgi?id=205892
I suspect that would require some fundamental restructuring that would
break APIs, so that's not so likely to happen even with contributor
involvement...

Vasanth,
I think so.
