I need to build a figure consisting of an icon and text under it. However,
I would like to create connections between the icon nodes only. In other
words, the text under the icon should not be selectable or countable as a
connection anchor, but still move with the icon when it is dragged.
I am using the code posted by Guy Slade (
http://dev.eclipse.org/newslists/news.eclipse.tools.gef/msg0 0118.html ),
but the container handles both (the icon and the text under it) as a
single until. How can I make the icon the only selectable for
connections?
Thanks in advance,
Al.-

Randy:
Thank you for your reply. Did you mean write my own anchor implementation
similar to the one implemented in the org.eclipse.gef.examples.ediagram
plug-in? That sort of worked since I can now see the selection rectangle
only around the icon, not including the label. However, the labels are
clipped and it forces me to resize the selection rectangle causing the
connection to start and end where the labels begin and end. How can I get
the connection to reach the connectors and go through the text/labels? Is
that possible?
Thank you in advance,
Al.-

No, the EDiagram example doesn't do exactly what you want. Something =
like this:=20
new ChopboxAnchor(getERUPTaskFigure().getTheIcon());
However, as you will see when you try that, the connections will cut =
through the text to connect to the icon. You'll have to handle that =
case smartly.
BTW, in your ERUPTaskFigure, the task icon should be an ImageFigure, not =
a Label.

Your subclass of ChopboxAnchor can take a HandleBounds in the =
constructor. Then, using the handle bounds and the actual bounds of the =
figure, you'll be able to determine if a connection is going to cut =
through text, and if so, you can just return a point that is on =
circumference of the figure, rather than the icon.
Once you have this working, maybe you can contribute it to the EDiagram =
example :-)

No, the EDiagram example doesn't do exactly what you want. Something =
like this:=20
new ChopboxAnchor(getERUPTaskFigure().getTheIcon());
However, as you will see when you try that, the connections will cut =
through the text to connect to the icon. You'll have to handle that =
case smartly.
BTW, in your ERUPTaskFigure, the task icon should be an ImageFigure, =
not a Label.

Thank you for your reply. Did you mean write my own anchor =
implementation similar to the one implemented in the =
org.eclipse.gef.examples.ediagram plug-in? That sort of worked since I =
can now see the selection rectangle only around the icon, not including =
the label. However, the labels are clipped and it forces me to resize =
the selection rectangle causing the connection to start and end where =
the labels begin and end. How can I get the connection to reach the =
connectors and go through the text/labels? Is that possible?=20

In my subclass of ChopboxAnchor, I have overridden the getLocation method
to implement your suggestion and check if the line segment intersects the
TextFlow's bounds. However, PointList#intersects(Rectangle) is not
returning true when the line segment intersects. I probably did not
understand correctly your previous message, please let me know if you see
what I am missing.
Thank you in advance,
Al.-
public Point getLocation(Point reference)
{
Rectangle textRect = null;
PointList pointList = new PointList();
textRect = taskFigure.getLabel().getBounds().getCopy();
taskFigure.getLabel().translateToAbsolute(textRect);
Rectangle r = Rectangle.SINGLETON;
r.setBounds(getBox());
r.translate(-1, -1);
r.resize(1, 1);
getOwner().translateToAbsolute(r);
float centerX = r.x + 0.5f * r.width;
float centerY = r.y + 0.5f * r.height;
if (r.isEmpty() || (reference.x == (int) centerX && reference.y ==
(int) centerY))
return new Point((int) centerX, (int) centerY);
float dx = reference.x - centerX;
float dy = reference.y - centerY;
float scale = 0.5f / Math.max(Math.abs(dx) / r.width, Math.abs(dy) /
r.height);
dx *= scale;
dy *= scale;
centerX += dx;
centerY += dy;
Point linkPoint = new Point(Math.round(centerX), Math.round(centerY));
pointList.addPoint(linkPoint);
if (pointList.intersects(textRect))
{
// I am not doing anyhting here yet...
// I just want to check if intersects() returns true
return linkPoint; // Apply offset before return it..
}
return linkPoint;
}
