Hi!

Is there a newer version available with protected useRealtimeFigure or a
setter/getter for this member?

Using the real figure doesn't work in applications that allow you to
reparent a figure. The figure would get clipped by its current parent.
Also, moving the figure at all fights against the layout manager. If the
layout decided to layout for some odd reason, such as showing target
feedback caused it to invalidate itself, or auto-scroll caused it to
revalidate, then the layout manager would undo any feedback, and you'd get
bouncing and flashing, etc.

So, we intend to provide something slightly better than the current dashed
XOR rectangle. We would like to take a snapshot of the figure being dragged
by asking it to paint to a buffer. Then, we'll make that buffer 50% opaque,
and the feedback will be this "ghost" version of the original Figure. We
might provide or choose other renditions, such as just capturing the
geometry of the figures paint calls, etc.

I noticed similar problems while doing some tests.

Is there something ready for testing or something for playing with?

Another question, can I modify the alpha blending of a image/figure/shape in
Draw2d/GEF?

Only SWT Image supports alpha.

But is GEF/Draw2D capable of showing and image with
image.getImageData().alpha set to a value between 0 and 255?

It doesn't seem so. I tried several times but the Image alway appears full
with no blending.

Hi!

In an early phase of developing with GEF I got a nice focus for EditParts.
It was no border, just a small triangle in each corner. I don't know how to
reproduce this again in my own implementation of NonResizableEditPolicy.

Randy, any ideas what I mean?

Yes. Those triangles were unique to GEF, so the user was not likely to know
what they meant.
Now you get 4 square handles. Is this a problem? I suppose sometimes this
looks bad on really small objects.

Other application make the handle look like a "lock", meaning that the size
is locked. This is a little strange if the location is not locked, just the
size.

Can you describe your usage more? Unless you have good motivation you
should just use the default. we might also consider using smaller handles
based on the size of the figure.

"I love these triangles." ;)

Anyway, as you might know, I have a Snap-To-Grid Layout. My figures in GEF
are all not resizable. I find the border with the 4 squares in each corner
not a good choice for out UI. The user may think he could resize the figure.
Of course you present the user the right mouse cursor but that doesn't fit
for us.

Thus, you can say that I only want the "triangle" focus back for design. But
I think is very important. I tried to change the focus border myself by
overwriting NonResizableEditPolicy#showfocus() and creating my own
implementation of FocusBorder but I didn't get a result (still the same
border).

If you want to provide the border with squares as default focus, it's ok if
you can also provide the triangles (without black border around figures) as
an alternative :)

Any solution for switching back to smart triangle focus already?
