Hello dear PV-coders,
In my quest for making a custom PV plugin, I’m currently trying to press a (qt) button in my C++ plugin via the PV python console.
I guess, I am looking for a functionality, similar to
Q_PROPERTY, which would add a python method to a C++ plugin, enabling one to write
plugin.Function() in a console.
Though it sounds complicated, all I need is to emit a signal, which would trigger another C++ function and do what I need.
What is the correct way to achieve this? Thank you.
I’m not sure why do you need a python method here. could you elaborate the need ?
I have a preprocessing step and it is currently triggered by a button. Now, I want to do these actions from the python console:
plugin.parameters = [1, 2, 3]
But as I said, all I need is just to send a signal. I don’t need complex python code.
Do these operations are done server side or client side ?
Sorry, for a delay.
I’m not sure what is the difference. The Preprocess() function is defined in the body of a C++ plugin, i.e. it is plugin’s method.
is Preprocess() a method of a VTK filter? does it needs access to the data ?
It is not a filter in the VTK sense, but it indeed accesses the data and updates them, yes.
Then you should use a Property to trigger the call in the proxy controlling this class.
