Hi,
Couple months ago I post a message about how to make label to have several
editable parts. Randy Hudson, that can be done if a simple change is made in
GEF. Would you please tell me if that change is in the latest build?
Thank you.

If we make a simple change in GEF (SelectEditPartTracker), Hal could use
this figure with a single editpart. The change would be to make "direct
edit" a LocationRequest. Hal could just take the Request and compare its
location to the location of the 3 labels.
However, both of these solution only work with the mouse. You would still
have to figure out how to switch between the 3 CellEditors with the
keyboard.

location on the Canvas
getMonthLabel().translateToRelative(where); //You could use any of the
3 labels for this translation
if (getMonthLabel().containsPoint(where)){
performMonthDirectEdit();
} else if ...
//etc.

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.
