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 ??
