HI all,

I am using the following method to make the viewer uneditable,but I always
get a NULL value from viewer.But if I use the createPartControl I can get
it to work,but in my case I have to call this method with a button from
MessageDialog after the editor has been created.Is there any way I can get
it to work.


public void setEditable(boolean editable) {
ISourceViewer viewer = getSourceViewer();
if (viewer != null) {
viewer.setEditable(editable);
}
}
I get viewer as NULL,I have tried to use the same line
(ISourceViewer viewer = this.getSourceViwer();) in another code but It
also doesnot work.
While using the above method with createPartControl I can call this from
another class but I get a NullPointerException on the
super.createPartControl(composite parent).
I would really apprecaite any pointer.

Syed

The sourceViewer is created in createPartControl(). The value is not
available until super.createPartControl() has completed.

Bob,
Alright that is what read also,but can you tell me how to get rid of the
runtime error "Argument can't be null" at line super.createPartControl
that I get after calling createPartControl from another class.I need to
get the sourceViewer for my method.Is there any other way to get this
done.

Thanks

Syed

Huh? This is in an editor plugin, right? You can't call createPartControl().
It gets called by the framework.

What's your hurry? The viewer isn't editable before it is created. Just set
a flag in your editor and when the part control is created, do whatever you
need to the source viewer.

I understand what you are saying but I invoke setEditable method after the
editor is created,then according to what you are saying I should have the
viewer(I Think).
What actually happens is that I open up the editor frist then through the
Dialog I invoke this method.So if the editor has been opened up then there
should be a viewer.I tried to do the same for retriving text from the
editor and I was having the same problem then.
Or am I missing something here.

Thanks for all your help

Notwithstanding Andrew's response, I believe the source viewer is not
available until after createPartControl() has been called. If you are trying
to get it beforehand, you can solve your problem with a hack like this:

private Boolean deferSetEditable = null;

public void setEditable(boolean editable) {
ISourceViewer viewer = getSourceViewer();
if (viewer != null)
viewer.setEditable(editable);
else
deferSetEditable = editable ? Boolean.TRUE : Boolean.FALSE;
}

public void createPartControl(Composite parent) {
super.createPartControl(parent);
if (deferSetEditable != null && getSourceViewer() != null) {
getSourceViewer.setEditable(deferSetEditable.booleanValue()) ;
deferSetEditable = null;
}
}
