@omz Welcome BACK !!!!!!!!!!!!!!!

@cvp No it works!! Thank you very much !!

@cvp i am using pythonista beta, the new one.

The code:

import ui
from objc_util import *

UIHoverGestureRecognizer = ObjCClass('UIHoverGestureRecognizer')

class MyView (ui.View):
	@on_main_thread
	def __init__(self, *args, **kwargs):
		ui.View.__init__(self, *args, **kwargs)
		self.background_color = 'lightgray'
		
		self.v = ui.View()
		self.v.frame = (10,10,100,100)
		self.v.background_color = 'white'
		self.add_subview(self.v) 
		
		handler = UIGestureRecognizerDelegate(UIHoverGestureRecognizer, self.v, self.hover)
		
	def hover(self, data):
		if data.state == 1: # began
			data.view.background_color = 'red'
		elif data.state == 2: # changed
			pass
		elif data.state == 3: # ended
			data.view.background_color = 'white'
		#print(data)



v = MyView()

There is this error with your code:

@cvp Can you write an example with it ?

is there a built-in way to detect if the mouse cursor is on hover a view ?
if not, can i do it with objc_util

Like this on swift UIkit:

class MyView: UIView {
    override func hover(_ hover: Bool) {
        super.hover(hover)

        if hover {
            // This code will execute when the mouse cursor enters the view.
        } else {
            // This code will execute when the mouse cursor leaves the view.
        }
    }
}

@omz Welcome BACK !!!!!!!!!!!!!!!

@cvp
No, I mean position of mouse cursor. Not touch position.

When i use ui library, is there a way to know these things:

• where is the cursor with x, y ?
• is the cursor on top of a view ?

Is these things possible with ui ? Or at least is there a library in pythonista can do one of these things ?

Yes Yes Yes!!!! Thank you very much dude !!!

How to get the touch position on ui.View() ? Without using any library exept “ui” ?

How to do subprocess.Popen() on pythonista ? It’s not work, its say:
