Creating new js objects

If you add a new marker to the map. pyqtlet2 will create a new javascript object. Due to constraints of QWebChannel(), all objects which a registered after the application start, will be not able to send notifications to the main application!

I have a idea, we regiseter a eventDelegateObject before application start, all the later registered objects' notification be sent to this eventDelegateObject, then this delatation dispatch it to right Python object.

Hey @alexhuangdz Did you already experiment with this, or have a version?

[alexhuangdz]

I tried on my local version ,it works.
