Unification of Marquee and selection tool [message #13979]

Hi
i'm using the selection and marquee tools in my palette, and i was
wandering is there a way to not use them at all (i.e., the user will not
need to select Selection or Marquee from the palette), but the default
behaviour will be some sort of unification between them, i.e., upon click
there will be a selection behaviour, but if there was a mouse button down,
and then draging, then the behavioiur will be as a marquee, creation a
rectangle of selection.
thanks
yoav

Which is okay, because I'm after something a little different; a simple
click makes a Selection happen, which is fine, but I need a drag to start a
connection on the EditPart I'm pointed at. Is there any class/method in the
logic example to start me toward an answer? Does my entire EditPart need to
be a connection terminal for anything connection-related to happen?

advTHANKSance.

The question is regarding the marquee tool. Click in the white space on the
diagram and drag, you get the marquee tool.

Clicking anywhere causes a connection? or only in a special region. If you
just need this in a special region, I would do this using a Handle. The
handle can be transparent, assuming you have some sort of terminal
decoration on the node. A handle can be visible all the time; the part
doesn't have to be selected. The handle would then return the
ConnectionCreationDragTracker as its DragTracker.

Hi!

You must overwrite EditPart#getDragTracker(Request). My root edit part
simply returns a new MarqueDragTracker there.

Ideally a drag anywhere on the EditPart would start the connection. I'll
see what I can make of it between this and Gunnar's reply to Yoav, but if
you have any other thoughts I'll be checking back.

(or parhaps a very large rectangular Handle?)

Hi
i did as you suggested, but after i mark a region that includes several
editparts, only one of them gets selected. does anyone knows what could be
the problem?
thanks

partially solved. it seems that in order to select an editpart, all of its
figure should be in the marked region. how can i change this behaviour to
be similar to the way the marquee behaves on the windows deaktop, i.e.,
even if part of the figure is in the marked region, the editpart will be
selected.
thanks
