How to transport data based on signal/slot bewtten two connector? #69

Closed maobaoqi closed 4 months ago

maobaoqi commented 4 months ago

Hi, I clone this project and compiled, I think this is a great work for learning qt graphics flow.

I try to use this project to create a algorithm simulator system. There is a basic question, how to transport data between two demo operator using connector, for example, one connector is INPUT and another is OUTPUT, demo operator contains a core process function.

Maybe the key point is that how to auto connect one connector signal to another connector slot when draw the fancywire. Any good and efficient ideas? thanks !

This library is a graphics/view framework only. Any sort of actual logic needs to be implemented by the consuming application.

The Netlist (and NetlistGenerator) serve as the interface to that logic. If you need more fine grained control you can implement your own NetlistGenerator or directly tap the wire_system API.

Overload the QSchematic::Items::Node::paint() function. The example/demo shows how to do this.

Please open a new issue with matching title if you have more questions :)
