Hello,

I've got a problem with the look of the guides on my GEF ruler. When I
create one, the dotted line goes correctly over the whole editor area,
indicating the horizontal or vertical position of the guide. But as soon
as I let go of it (mouse button released), it looks like in the attached
image. I've been trying to figure out why several days, with no
success. However, the snap-to behaviour works as expected! If anyone has
an idea why it does what it does, i'd be most thankful.

Regards,
Michael B

Is the horizontal constraint being set properly on the guide layer? Look at
GuideEditPart#createFigure() and see if isHorizontal() is returning proper
values. If that's working fine, set a breakpoint in
GuideLayer#setFreeformBounds and see what's going on. You should also
search for this on the newsgroup. I think somebody had a similar problem
once, but I don't remember what they were doing wrong.

Hello!

I have no solution for your problem ;-)
but would ask you about how you have implemented these rulers and guides.
I would be very happy if you could give me some code examles or something!
Because I don?t know how it work and I could not find any documentation.

Thx

Hi,

as of now I was unable to find a solution (but then, I tried only for a
few hours before I got frustrated). The hints that Pratik gave me seemed
to reveal no remarkable abnormality in my code. The funny thing is that
it used to work some time ago... :-(
Sorry, but I can't help you (yet). Should you find a solution before I
do, please tell me about it!

Oops, Sorry... *g*
I just realized I answered to a question that was never asked. I just
adapted the sample code from the logic example and stuffed it into my app.
The most important part is to set the right properties to the
graphicalViewer, like this:

getGraphicalViewer().setProperty(RulerProvider.PROPERTY_HORI ZONTAL_RULER,
this.horizontalRuler );

getGraphicalViewer().setProperty(
RulerProvider.PROPERTY_VERTICAL_RULER,this.verticalRuler );

getGraphicalViewer().setProperty(RulerProvider.PROPERTY_RULE R_VISIBILITY,
new Boolean( true ) );

(hint: horizontalRuler / verticalRuler are instances of RulerProvider)


Additionally, in the method createGraphicalViewer(), you have to use a
RulerComposite as argument, like this:

protected void createGraphicalViewer( Composite parent )
{
this.rulerComp = new MyRulerComposite( parent, SWT.NONE,
getActionRegistry() );
super.createGraphicalViewer( this.rulerComp );
this.rulerComp.setGraphicalViewer( ( ScrollingGraphicalViewer )
getGraphicalViewer() );
}


That should get you started, you'll sure find the rest by searching this
newsgroup.

Michael Böckling

Hi again!

The problem with the wrong displaying of the rulers occures when I use
*ScalableRootEditPart* instead of *ScalableFreeformRootEditPart* as the
Root Editpart in the *configureGraphicalViewer()* method.

So maybe you could solve the problem by changing this... but...
in my Application I use a Image on a Label as the Background figure.
And when I use the *ScalableFreeformRootEditPart* it displays not the whole
Image.
Can I set any constraints to this *ScalableFreeformRootEditPart* to solve
my problem???

Thx for help!!

Regards,
Danny

Yeah,

I have found the solution in the IBM Redbook about GEF and EMF...
I have to use a ImageFigure as the figure that implement FreeformFigure.

Hehe, itŽs better to read before post...

Danny
