[Paraview] Adding functionality to the apply event

[Cory Quammen]

Hi Chris,

The pqPropertiesPanel fires off applied() and applied(pqProxy *) signals
when the "Apply" button is clicked. Would it work for you to connect one of
these signals to a slot in a custom Qt-side class in your plugin? If so,
can make your plugin an autostart plugin (see [1]) to instantiate your Qt
class, and connect it to signals fired from the pqPropertiesPanel. You
should be able to do this by looping over all the pqPropertiesPanels like
this in your plugin's custom Qt class onStart() slot:

foreach (pqPropertiesPanel* ppanel,
mainWindow->findChildren<pqPropertiesPanel*>())
{
  connect(ppanel, SIGNAL(applied()), myCustomQtObject, SLOT(onApplied()));
}

where you do your additional actions in the onApplied() slot.

Please let me know if that wasn't clear.

Cory
