I want to be able to click on nodes and add text entries, much like that of
a UML Class node. I understand from reading the archives that I would be
using DirectEdit and CellEditor. I was wondering if there was any article
or tutorial on how I can get a start on making a node editable.
Thanks.

Basically, you just receive the DirectEditRequest, startup a
DirectEditManager, and provide the command which performs the edit in the
end. You may also provide optional feedback. See LabelDirectEditPolicy in
logic example.

For some reason, I am not able to get the cell editor to show up:
I copied stuff from the Logic example:
1. I added the following methods in my edit part:
protected void createEditPolicies()
{
installEditPolicy(EditPolicy.COMPONENT_ROLE, new
FilterEditPolicy());
installEditPolicy(EditPolicy.NODE_ROLE, new
SFTEditGraphicalNodeEditPolicy());
installEditPolicy(EditPolicy.GRAPHICAL_NODE_ROLE, null);
installEditPolicy(EditPolicy.DIRECT_EDIT_ROLE, new
LabelDirectEditPolicy());
//installEditPolicy(EditPolicy.COMPONENT_ROLE,new
LogicLabelEditPolicy());
}
private void performDirectEdit(){
if(manager == null)
manager = new LogicLabelEditManager(this,
TextCellEditor.class, new
LabelCellEditorLocator((StickyNoteFigure)getFigure()));
manager.show();
}
public void performRequest(Request request){
if (request.getType() == RequestConstants.REQ_DIRECT_EDIT)
performDirectEdit();
}
Then, I added the following classes:
1. LabelDirectEditPolicy
2. LogicLabelCommand
3. LabelCellEditorLocator
4. LogicLabelEditManager
(All exactly as it is in the Logic Example)
My createFigure in the editPart looks like this (StickyNoteFigure in my
program simply extends ImageFigure and has the same methods as the one on
the logic example):
protected IFigure createFigure()
{
Image andGate = new Image (null,
"C:/eclipse/workspace/sft/src/sft/editor/images/andGate.bmp");
StickyNoteFigure gate = new StickyNoteFigure();
gate.setImage(andGate);
Label label = new Label(label_);
label.setLocation(new Point(0,0));
gate.add(label);
Point location = new Point(60,50);
gate.setLocation(location);
gate.setSize(new Dimension(70,70));
return gate;
}
protected void refreshVisuals()
{
NodeModel node = (NodeModel)getModel();
StickyNoteFigure gate = (StickyNoteFigure)getFigure();
Point p = node.getLocation();
Dimension s = node.getSize();
Rectangle r = new Rectangle(p, s);
((GraphicalEditPart) getParent()).setLayoutConstraint(this, gate,
r);
super.refreshVisuals();
}
What am I missing?
Thanks for any help...
Swami.

would be to simply click on the edit part. Sorry, I'm still a newbie :-)

Nope, your right. You need to click on the part to select it, then click a
second time to direct-edit the same part. This is how the "platform" (read
windows file explorer) works.

Ok, here is the code where I observed as you had asked me to:
protected boolean handleButtonUp(int button) {
if (isInState(STATE_DRAG)) {
performSelection();
if (getFlag(FLAG_ENABLE_DIRECT_EDIT))
performDirectEdit();
if (button == 1 && getSourceEditPart().getSelected() !=
EditPart.SELECTED_NONE)
getCurrentViewer().reveal(getSourceEditPart());
setState(STATE_TERMINAL);
return true;
}
return false;
}
I steped over each line when the control came into this method...it returned
from performDirectEdit and then later stops debugging when it reaches the
folowing method in Workbench:
private void runEventLoop(Window.IExceptionHandler handler, Display display)
{
runEventLoop = true;
while (runEventLoop) {
try {
if (!display.readAndDispatch()) {
getAdvisor().eventLoopIdle(display);
}
} catch (Throwable t) {
handler.handleException(t);
}
}
}
The program doesn't halt or anything--I can continue to drag further objects
from my pallete, but the direct edit editor does not show up when the edit
part is clicked.

You've stepped through to the event loop of the application where it waits
for Windows to send more message. You need to step Into (F5)
performDirectEdit(), and step into editpart.performRequest(), etc., and find
out if your editpart is receiving the request, if it constructs a
celleditor, if it is actived, etc.

Unhandled event loop exception
Reason:
java.lang.NullPointerException
But what I'm confused about is that how come the Logic example works with
the other JRE?
Thanks,
Swami.
