Thanks. I try this, but the getLocation() always return me the *SAME*
co-ordinate regardless where I click on the label.
Here is what I did:
- create a new LocationEditManager and in its createDirectEditRequest(),
copy the location from the incoming directEditRequest to this new Direct
edit request that it is going to create.
protected DirectEditRequest createDirectEditRequest(){
DirectEditRequest req = new DirectEditRequest();
if (request != null){
req.setLocation(incomingDirectEditRequest.getLocation());
}
req.setCellEditor(getCellEditor());
return req;
}
- create a new DirectEditPolicy, I print out the location of the request:
But the location is ALWAYS the same, regardless where I click the label:
protected void showCurrentEditValue(DirectEditRequest request) {
System.out.println ("showCurrentEditValue x:" + request.getLocation().x + "
y:" + request.getLocation().y);
LogicSubpart host =
(LogicSubpart)((AbstractGraphicalEditPart)getHost()).getMode l();
//...
}
- in my editPart, I install this new direct edit policy and create my new
directEditManager when necessary.
Could you please if I miss anything? What I want to do is I have a label
looks like this "XX / MM / YY", if user clicks between the beginning of the
label to the first "/", I only pops up "XX". Same thing if user clicks
between the first "/" and the last "/", only "MM" will pop up.
Thanks for any help.

Hal,
Direct edit happens during SelectEditPartTracker.performDirectEdit(), which calls
performRequest(Request) on your EditPart. The location I printed out in this method changed when I
clicked on different places on the LogicLabel. Is this where you're getting the incoming request?
Are you creating a new manager for each direct edit or are you caching the manager somewhere in
between direct edits? Try stepping through the performRequest(Request) in your EditPart and make
sure the location is being updated properly in your DirectEditManager.
Hope this helps.

Thanks, I will try that.
Another question that I have is the co-ordinate I get is absolute, how can
I get it with respective to the beginning of the label?

Calling label.translateToRelative(point) will give you that point relative to the label's coordinate
system.

Eric,
Thanks for your response.
I print out the value of the co-ordinate of the request location (before and
after calling translateToRelative()),
but I don't understand is why X is 39 and Y is 27 after I
translateToRelative()? From the 3rd result, the width of the host is 24 and
height is 13, so X should be 0 < x < 24 and Y should be 0 < y < 13 right?
how come x is 39 and y is 27?
Before x:188 y:163
After x:39 y:27
host.x:0 host.y:0 host.width:24 host.height:13
<< the code>>
Point location = request.getLocation();
System.out.println ("Before x:" + location.x + " y:" + location.y);
LogicSubpart host =
(LogicSubpart)((AbstractGraphicalEditPart)getHost()).getMode l();
IFigure figure = ((AbstractGraphicalEditPart)getHost()).getFigure();
figure.translateToRelative(location);
System.out.println ("After x:" + location.x + " y:" + location.y);
System.out.println (" host.x:" + host.getLocation().x + " host.y:" +
host.getLocation().y + " host.width:" + host.getSize().width + "
host.height:" + host.getSize().height);

"Relative" in Draw2D means that the coordinate is relative to the figure's
bounds, not relative to it's top-left corner. This is because most figures
are positioned in absolute coordinates.
In your case, the figure's bounds were probably at something like x = 20, so
0 <= (39-20) < 24.
