How to send key <ENTER> or user other defined keys?

[damies13]

Hi I would like to know how to send key ?

I have tried the following but none of these worked:

• vnc.send_key(KEY_KP_Enter)
• vnc.send_key(KEY_Enter)
• vnc.send_key('KEY_KP_Enter')
• vnc.send_key('KEY_Enter')
• vnc.send_key('\r')
• vnc.send_key('\n')

I was able to send other keys (e.g. vnc.send_key('a')) just not any defined key

Note: I would have expected a KEY_Enter around line 40-50 in rfb.py.

Additional Info:

BTW vnc.get_screen() seems to be missing but I found a workable alternative, I figured out I could use this to get an image of the vcn screen and confirm the results of what I sent:

>>> 
>>> Image.frombytes('RGBA', vnc.screen.size, pygame.image.tostring(vnc.screen.canvas, 'RGBA')).show()
