Check multi-keys press

yaley

@cvp yes, but the problem is when the second press joined CustomViewController_pressesChanged_withEvent_() didnt run about it

yaley

@cvp You’re method is correct, just i am stupid, i typed wrongly, i set the variable to True in the pressesEnded def

XD

cvp

@yaley right, just tested

yaley

Wait no, why??? Why my first test is correct and then the second test is not working?????

cvp

@yaley for me, changed not called
If you change something in a created class, restart Pythonista

yaley

@cvp here’s my code, I’ve tried to restart Pythonista

def CustomViewController_pressesBegan_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].key().keyCode()
	
	activeKeys[keyCode] = True
	
def CustomViewController_pressesEnded_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].key().keyCode()
	
	activeKeys[keyCode] = False
	
def CustomViewController_pressesChanged_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].keyCode()
	
	activeKeys[keyCode] = True

cvp

@yaley you should add some print in each method to check if called

cvp

@yaley said

keyCode = presses[0].keyCode()

Key() missing in changed

cvp

@yaley only began is called once with left arrow, second with right arrow

Thus, forget changed, and all is ok because two keys imply 2 calls to began

yaley

@cvp thanks it solved!!!

yaley

@cvp looks like i found the problem, if in the changed def, i set activeKeys[keyCode] = presses[0].key().keyCode() it doesn’t work, but if i set activeKeys[keyCode] = presses[0].keyCode() then it works :)

cvp

@yaley sorry, perhaps I (or my eyes) become too old, but I don't see the difference

yaley

@cvp no it’s my wrong again xD They’re absolutely no difference before, lol

yaley

@cvp I’ve already changed it, read it again :D The difference is [0].key().keyCode() and [0].keyCode()

yaley

Wait, um, after i added print() the pressesChange is not activating

cvp

@yaley ok. And did you trace, sure that changed def is called?

Sorry: was typing while your previous post was coming

yaley

@cvp i dont think that that def was called :(

cvp

@yaley but do you really need it? The doc says it is called if you change something in your key press, like force. If you know which key is down and up, and when, you have all you need, haven't you?

yaley

Yep! Maybe…. No need!

yaley

@cvp But the main problem is just when arrow keys will happen, just like umm i give you an example:
I am detecting keys with ui.Textfield() And now i start pressing left arrow key. So in the input it goes left ( the selection bar ), but if the right arrow keys joined the right arrow key, the selection bar of input still goes left.
