Hi all,
I have asked this question couple of weeks ago but as couldn't solve the
problem as my editor was not working properly.
Actually I want to make the editor readonly by using SetEditable method
and for that I am trying to get hold of the viewer through ISourceViewer
by using the following code but can't get it to work and always get a null
value for
view.
ISourceViewer viewer = getSourceViwer();
I am calling the following method with a click of a button from
messageDialog but don't get it to work as I get a null vlaue for the
viewer.
public void setEditable(boolean editable) {
ISourceViewer viewer = getSourceViewer();
if (viewer != null) {
viewer.setEditable(editable);
}
}
My earlier quest of the solution was a hack by Andrew McCullough given
below that was getting me the viewer of the editor but I can't get the
setEditable(boolean) to work with it,and I don't know how to debug it.
Following is the method that I am using in my JavaEditor example.
if (part instanceof TextEditor) {
TextEditor editor = (TextEditor)part;
ITextViewer viewer =
(ITextViewer)editor.getAdapter(ITextOperationTarget.class);
if (viewer != null) {
viewer.setEditable(false);
}
}
I have set breakpoints before and after this viewer.setEditable,all of
them are called but the editor remains the same.
I would realy apprecaite any help.
Thanks
Syed
