Yes, by selecting a different source, the filter menu is enabled. When I
go back to my reader the filters are again disabled. So I feel like
something is not being set correctly when I press accept(). Or maybe it
has something to do with the fact that the data hierarchy is Multi-block
Dataset -> Unstructured Grid?
My accept looks as such:
[code]
void
MyReaderPanel::accept()
{
vtkSMStringVectorProperty* lb =
dynamic_cast<vtkSMStringVectorProperty*>(
this->proxy()->GetProperty("lbSelection"));
lb->SetNumberOfElements(this->widgets.lbSelection->count()*2);
for(int i = 1; i < this->widgets.lbSelection->count()+1; i++)
{
lb->SetElement(2*i-2,
this->widgets.lbSelection->item(i-1)->text().toStdString().c_str());
if(this->widgets.lbSelection->item(i-1)->checkState() ==
Qt::Checked)
{
lb->SetElement(2*i-1, "1");
}
else
{
lb->SetElement(2*i-1, "0");
}
}
this->proxy()->UpdateProperty("lbSelection", 1);
vtkSMStringVectorProperty* lb2 =
dynamic_cast<vtkSMStringVectorProperty*>(
this->proxy()->GetProperty("lbSelection"));
}
[/code]

Try selecting something else in the pipeline browser and then select
the filter again. Does that seem to update the menus correctly?

Everything in the information tab does look correct. (Sorry I forgot to
mention that I switched from PolyData to UnstructuredGrid earlier).
Basically everything works as it should, but I don't have the option to use
the filters on the data.
With:
Type: Unstructured Grid
Num Cells: 159
Num Points: 159
I figured I would have at least a few filters. Or after I selected a few
points some filters would show up.

But you're saying the information tab doesn't show the data
information correctly, right? That implies that some essential
"notification" is missing. Hard to say which one without looking at
the code, however.

The custom accept is on a custom panel. The custom accept just makes sure
the GUI selections are sent to the vtkobjects. When apply is pressed on
the
panel, the data gets updated and plotted on the 3d graph (Vertices will
be
updated based on time). Thus I believe the GUI is being updated as it
should. I can press the play button and watch everything move as it
should.
However, I am never able to filter any of the data even if I select
points.

"Custom accept"? What's that? And yes, if you are doing some funky
stuff to update the reader, it could explain why the GUI never
realizes that the reader has been updated.

Once I hit apply, I see Data Hierarchy: Multi-block Dataset -> 0:
Unstructured Grid, 1: NA
with Unstructed Grid selected Statistics shows:
Type: Unstructured Grid

Num Points: 159
Memory: 0.011mb
My reader does have a custom accept. Could that be the issue?
Thanks,

I have created a reader which makes a vtkMultiBlockDataSet containing
a
vtkPolyData. It reads in 100 some points and plots lines between
them.
After
I read them in, I don't have the option to use any filters on the
data.
Any
idea why this is disabled? Could it be related to the data having
time
steps?
Thanks,
