I was stupid... missing set_needs_display in the showDrawing function!

Hello,

I have a simple view with a button and a subview where I want to draw. I want that the drawing happens when I press the button. I set up the following code

# coding: utf-8
import ui
class DrawView (ui.View):
	def __init__(self):
		self.path = ui.Path()
	def draw(self):
		if self.path:
			self.path.stroke()			
def showDrawing(sender):
	v = sender.superview
	v['secondView'].path = ui.Path()	
	v['secondView'].path.move_to(20,20)
	v['secondView'].path.line_to(400,400)
	v['secondView'].path.line_width = 5
# Global View
h, v = ui.get_screen_size()
myView = ui.View()
myView.background_color = 'red'
myView.present('full_screen',hide_title_bar=True)
# Adding Button
myButton = ui.Button()
myButton.frame = (50,50,v/3,100)
myButton.title = 'Show Mesh'
myButton.background_color = 'white'
myButton.action = showDrawing
myView.add_subview(myButton)
# Adding Draw View
drawView = DrawView()
drawView.name='secondView'
drawView.frame = (h/2,50,v/3,800)
drawView.background_color = 'pink'
#drawView.path = ui.Path()	
#drawView.path.move_to(20,20)
#drawView.path.line_to(400,400)
#drawView.path.line_width = 5
#drawView.path.stroke()
myView.add_subview(drawView)

but nothing happens if I handle the paths inside the action linked to the button. Any hint? Thank you in advance!

Hello, I really love Pythonista, but I am really missing the Aircode feature like Codea's one. Can you please consider to add it in the near future? Thanks!

ccc, I've already saw this, but I am not very satisfied with it. Plus, if it's really 5 lines of code, wouldn't it be very easy to include in the next update?

Hello, I need to display a plot in a custom view, and I am having hard time trying to figure out how to do it. I found this https://gist.github.com/anonymous/4e792e1194816431f053 that pretty much does all the job already, but I have no clue on how to put the plot into a view. Any hint? Thanks!

Here's the link to the code I have written/adapted that allows to draw plots directly into views. Enjoy!

Hello, how can I create and rotate a label of pi/2? I've already tried the GState() example, but when you input pi/2 the text disappears...

I think I figured it out by myself. Here's the code, in case someone needs it!

# coding: utf-8
import ui
from math import pi

# Preliminary step: create an empty UI and call it myview

# loading view
v = ui.load_view('myview')

# creating label
ylabel = ui.Label()
ylabel.text = 'Hello World'
ylabel.center = (v.width/2., v.height/2.)

#creating a transform object
rot = ui.Transform.rotation(-pi/2)

# applying the transform object to the label
ylabel.transform = rot

# adding the label to the view
v.add_subview(ylabel)

v.present()

Hello, this is probably a dumb question but I am having hard time in loading classes defined in another file (that has the same directory), into the current file. Any help would be really appreciated. Thanks!

worked perfectly!
