AttributeError: 'MainWidget' object has no attribute 'changeCurrentBoard'

[jiapei100]

I've already updated everything from PyQt4 to PyQt5. However, whenever I run the built .uPyCraft, I got so many signal-slot ERROR messages.

Such as:

AttributeError: 'MainWidget' object has no attribute 'changeCurrentBoard'
AttributeError: 'readWriteUart' object has no attribute 'uiRecvFromUart'
AttributeError: 'readWriteUart' object has no attribute 'ctrlRecvUartMsg'

etc.

It looks the signal-slot mechanics in PyQt4 and PyQt5, and Python2 and Python3, are totally different...

Can anybody help please?

Cheers
Pei

you can find
self.connect(self.ui,SIGNAL("changeCurrentBoard"),self.changeBoard)
in the file mainComponents.py.
And the corrspondant signal is
self.emit(SIGNAL("changeCurrentBoard"),self.currentBoard)
in uPyCraft.py.
Channel function is in mainComponents.py.
you can use notepad++ to open the files, search the key word, and find the corresponding signal &&Channel function.
