<div bgcolor="#ffffff" text="#000000"> Hi Jeff,<br>
<br>
thanks a lot for the hint. I found what I needed.
Unfortunately, I am not able to transfer the example to my<br>
own project. The CustomLinkView-project compiles fine.
However, when I add the following line to my project, I
receive an error:<br>
<br>
- from CustomLinkView: <br>
<br>
Connections->Connect(<br>
this->TableView->GetRepresentation(),<br>
vtkCommand::SelectionChangedEvent,<br>
this,<br>
SLOT(selectionChanged(vtkObject*, unsigned long,
void*, void*)));<br>
<br>
- my example:<br>
<br>
c_connections =
vtkSmartPointer<vtkEventQtSlotConnect>::New();<br>
<br>
c_connections->Connect(<br>
this->GetRepresentation(), // this points to my
own class which I derived from "vtkQtTableView"<br>
vtkCommand::SelectionChangedEvent,<br>
this,<br>
SLOT(selectionChanged(vtkObject*, unsigned long,
void*, void*)));<br>
<br>
- error:<br>
<br>
error C2664: 'vtkEventQtSlotConnect::Connect' : cannot
convert parameter 1 from 'vtkDataRepresentation *' to
'vtkObject *'<br>
1> Types pointed to are unrelated; conversion
requires reinterpret_cast, C-style cast or function-style
cast<br>
<br>
Do you have any idea why this is happening?<br>
<br>
Cheers,<br>

Jeff, <br>
<br>
thanks a lot for the reply. Could you please
give me a hint on where to implement this
strategy. I guess that there is an
interactor from which I should derive my own
"DoSomethingWithTheSelection"-methods? I
just don't know exactly how to start.<br>

<br>
in my graph visualization, I
would like to visually emphasize
all edges which are connected to
a user-selected node. Is<br>
there an implementation which I
can use for that purpose?
Otherwise, I would try the
following strategy: (1) get the<br>
selected node, (2) find incident
edges using
vtkAdjacentVertexIterator, and
(3) emphasize these edges.<br>
<br>
Best Regards,<br>
