Hello,
I have a figure which itself holds a container figure with several
labels as children. This is similar to the UML and schema editor examples.
Now I would like mouse drag events to always go to the outermost
enclosing figure, instead of to the label figures. I removed the layout
policy and thus got rid of the selection and drag feedback, but if I
click on a label, the outermost figure still loses focus, and I cannot
drag the figure.
I hope I am somewhat clear. This has kept me searching for a while, and
its late..
thanks,
christian

Or, if you want them selectable but not draggable, you would have to create
a custom DragEditPartsTracker which swaps out the source editpart as soon as
handleDragStarted occurs.

thanks for the tip. In fact, I would prefer to have the child parts
(database column parts inside a table part) selectable, but have the
drag apply to the table as a whole. I tried to do as you advised,
returning a custom DragEditPartsTracker from the getDragTracker method
of the inner part. The Tracker had the following method overridden:
protected boolean handleDragStarted() {
setSourceEditPart(outerPart);
return super.handleDragStarted();
}
However, this did not change anything. The columns are selectable (I
have a custom SelectionEditPolicy installed for the
EditPolicy.SELECTION_FEEDBACK_ROLE), but the drag operation does not do
anything.
thanks,
christian

Perhaps the source editpart has already been read and copied into the
Request, and setting it has no effect because the refresh request method
doesn't expect that parametere to change.
