Button like function key in pythonista keyboard

[Andrey]

Hi Team!
We have our owner keyboard and would like to have buttons like function key. For example F1, so if user press F1 - "f1"+Enter should be done to send "f1" to app.
We use command: keyboard.insert_text('f1')
Question.. Is it possible to add "enter" command without user press "Enter".
keyboard.insert_text('f1\n') is not working
Thank you.

@Andrey If external keyboard, see https://github.com/zrzka/blackmamba

@cvp
no, it is not external keyboard

@Andrey so, where do you want to have your F1 key?
Do you have an user keyboard, using keyboard module of Pythonista?
If yes, keyboard.insert_text('\n') works correctly
Which app would receive "F1"?

[Andrey]

@cvp
Yes we have an user keyboard, using keyboard module of Pythonista.
when we put keyboard.insert_text('\n') it just move cursor to the next row, but we need to send f1 to console.

@Andrey I see that you have inserted f1 then a new line, that's exactly what keyboard.insert_text('f1\n') does.
What is the problem?
Do you mean that "enter" is not "\n"? You 're right because you use this keyboard in Pythonista console but if you use it in another app, like mail, enter or \n is the same

@cvp
Is a way to press "enter" in Pythonista console via any code?

@Andrey Now, sorry, I only understand your request. No way with Python but perhaps with ObjectiveC.

Try this code with only one key-keyboard. It works.
For your info, the code simulates you press the standard Pythonista 'return' button of the last row.

import ui
from   functools import partial
import keyboard
from objc_util import *
class MyView(ui.View):
	def __init__(self, *args, **kwargs):
		super().__init__(self, *args, **kwargs)
		self.background_color = 'white' 
		iv = ui.Button()
		iv.border_width = 1
		iv.frame = self.bounds
		iv.title = 'F1'
		iv.action = self.Fkey
		#iv.action = self.auto_return
		self.add_subview(iv)
		
	def Fkey(self, sender):
		keyboard.insert_text(sender.title)
		ui.delay(partial(self.auto_return,sender),0.0)
						
	def auto_return(self,sender):
		global ylastrow
		o = ObjCInstance(sender)	# objectivec button
		while True:
			#print(o._get_objc_classname())
			o = o.superview()
			if 'KeyboardInputView' in str(o._get_objc_classname()):
				KeyboardInputView = o
				break	
		ylastrow = -1
		def analyze(v):
			global ylastrow
			for sv in v.subviews():
				#print(sv._get_objc_classname())
				#print(sv.text())
				if 'uibuttonlabel' in str(sv._get_objc_classname()).lower():
					if str(sv.text()).lower() in ['tab']:
						b = sv.superview()
						#print(sv.text(), b.frame().origin.x, b.frame().origin.y)	
						ylastrow = int(b.frame().origin.y)
					elif str(sv.text()).lower() in ['return','go']:
						b = sv.superview()
						if 'uibutton' in str(b._get_objc_classname()).lower() or 					'ckbkeybutton' in str(b._get_objc_classname()).lower():
							#print(sv.text(), b.frame().origin.x, b.frame().origin.y)	
							if int(b.frame().origin.y) != ylastrow:
								continue
							# how to simulate press the return button	
							UIControlEventTouchUpInside = 255
							b.sendActionsForControlEvents_(UIControlEventTouchUpInside)
							return True
				ret = analyze(sv)
				if ret:
					return True
		analyze(KeyboardInputView)

def main():
	v = MyView()
	if keyboard.is_keyboard():
		keyboard.set_view(v,'expanded')
if __name__ == '__main__':
	main()

@cvp
Thank You! I will look at the code. If it works next step for me to add it to our Pythonista keyboard. Is it possible? If we have to set up sending "Enter" for several keys only or "Enter" will send every times?

[cvp]

@Andrey Sure it is possible to add this code to your keyboard.
For keys which need to generate an automatic return, and only for them, in their action function, add at the end of the function

ui.delay(partial(self.auto_return,sender),0.0)

@cvp
Hello! Thank You a lot! It works.
