Hey Rafael,

First, you'll have to add a property to your filter to call the method that requests the writing as follows:

<SourceProxy name="MyFilter" class="vtkMyFilter">
  ...
  <Property name="Save"
            command="Save" />
  ...
</SourceProxy>

Then you have to create a custom object panel (look at the wiki for plugin examples) which adds a button and then a callback to do something as follows:

void pqMyPanel::callback()
{
  this->proxy()->InvokeCommand("Save");
}

Hey Folks,

I'm programming a filter, and I would like to be able to call automatically a 
writer(which I have also programmed), as the user hits a specific PushButton in 
the ObjectPanel.I mean: I want to have a SAVE button, and as the user hits it, 
it should save the model in my own format. How can I do this ?

Thanks,
Rafael March.
