[Paraview-developers] connecting to pqPropertiesPanel signals

[burlen]

Hi,

I'd like to add an (optional) auto update feature to the memory 
inspector panel that pulls updated stats from the server after each 
apply or delete. I've experimented a little with tying into the the new 
properties panel's signals and had a couple of issues,

1) The apply/delete signals aren't exposed app wide. I mean that it's 
difficult to get the instance of the panel, it doesn't necessarily even 
exist when the memory inspector is constructed. I didn't find other 
classes that provided a connection point to these signals.
2) The applied() signal coming out of the properties panel seems to fire 
before the server side update so the memory inspector refresh doesn't 
pull down the latest details. I think I need a postApplied signal that 
fires only after the server side update completes.
3) There are no signals fired for a delete event, and I would need a 
postDelete signal that fires after the server side finishes.

issue 1) suggests that it was never intended to directly connect to the 
new the new props panel's signals :-). I did happen upon the 
pqApplyPropertiesManager class which looks like it would help but it 
isn't wired up to the new props panel. Are there any plans for new props 
panel to expose these signals to the rest of the app? What's the best 
approach for what I want to do, am I missing an existing solution?

Thanks
