@technoway, I use a simple trick @ccc mentioned a long time ago. In 'Settings->Keyboards->Text Replacement' use 3 x comas to output 3 x ticks `
Not often you type 3 comas in a normal workflow.

A setting in the ui.View.present() that allows for the behaviour that if a touch is outside the view, it's the same as hitting the X or close button as many iOS apps do. Maybe only for custom ui.Views, as you can catch will_close

@omz , congratulations. A big milestone. I know you are a modest guy, but I hope you can appreciate other people's admiration for Pythonista. You should be very proud of yourself. I am one of your groupies 😀👍

@omz, the latest Pythonista beta 3, is great. The convert tabs , the snippets , the color entry. They can seem like small things. I am sure the functional code is easy, but the interfaces not so much.
But thanks again, I love it. 👍👍👍👍

@omz Would be great if there was a switch/activator to make the search in the file nav recursive. Maybe it's there already there. But if it is, please let me know. Would be a great feature

In a previous post I asked for help to get a circlular view working. @omz answered it for me. But look I am not a graphics guy, well I am not a really anything guy 😱

But with the simple solution he provided, I can see how it could be extended to do some very nice things. I was thinking of trying to do more with this. But I thought I really should leave it to the experts. I know others here can do a lot better job than me.

My idea is, any number of these mask views could be written using the techniques that @omz shows. Put into custom view classes that have a standard interface , then they could be used like plugins. If the containing class is defined very well, maybe with ABC's then as people write new ones using the base case they could for example be added to a list of view masks in Pythonista Tools.

Just my 2 cents worth. But personally, I think this is how we can leverage people's hard work here.

Ok, the sample code I have listed wants to access your photos. Thought it would give a better example being able to choose your own pics

import ui
import photos

class ImageMaskCircle(ui.View):
	def layout(self):
		self.frame = self.superview.bounds
		
	def draw(self):
		# https://forum.omz-software.com/topic/2902/circle-view-for-ui
		# @omz solution
		oval = ui.Path.oval(*self.bounds)
		rect = ui.Path.rect(*self.bounds)
		oval.append_path(rect)
		oval.eo_fill_rule = True
		oval.add_clip()
		ui.set_color('white')
		rect.fill()
	
class TestClass(ui.View):
	def __init__(self, image_mask = None, *args, **kwargs):
		ui.View.__init__(self, *args, **kwargs)
		
		self.iv = ui.ImageView()
		self.iv.image = ui.Image.from_data(photos.pick_image(raw_data=True))
		self.add_subview(self.iv)
		self.add_subview(image_mask)
		
	def layout(self):
		self.iv.frame = self.bounds
		
if __name__ == '__main__':
	f = (0,0, 80, 80)
	im = ImageMaskCircle()
	tc = TestClass(im, frame = f)
	tc.present('sheet')

@Chilibird , have a look at this forum post. I think it answers your question well.

In total agreement with everyone here. I love this product. As a retiree that had not programmed for years and years Pythonista was so compelling it got me back into programming as a hobby. The app and Ole deserve all the success in the world. Whatever success means for him.
I think you also should get special credit for putting up with us and our billion requests :)

A very simple utility to select/filter from the 148 CSS color names. Then you can copy the CSS name to the clipboard for pasting into your code. Done as a popover, as it makes sense for what it is. I like using CSS color names. Just makes things easy to read for me rather than seeing a bunch of rgb values. Also in combination with ui.parse_color you can an alpha to achieve a RGBA.

Anyway, here is a gist, I have done as a gist because I want to do more to it . I say in the comments.
But I just wanted to do something. I never finish things because I want it better and better. In this case I have just done what I could do comfortably. I mean the design. I know it's not great, but it could also be worse.

Again, it's super basic, but still useful if you use CSS colors.

@Webmaster4o , I know your heart was in the right place. It just sounded hash.

@pythonista21 , date has a day, month and year property you can access. So date.year, is an int.

@Drizzel , i just happened to watch this David Beasley YouTube Video today. If you haven't already watched I think you might find it intesting.

@ccc , its the / operator , need the // version in py3.x

for i, front_image in enumerate(self.front_images):
            x, y = i%5, i//5

@Tiowang, thanks very much. That fixed it. 2 occurrences to replace in the source file.

I am getting the same problem with installing other packages. I thought it might have something to do with the new python warehouse release and not using pip v10.x

I did selfupdate on stash to make sure it was the latest. Latest version is using pip v9 something.
I tried to upgrade pip in stash myself once and did something very wrong and had to reinstall stash. So i didn't try upgrading the pip myself this time.

@Gadgettyke, looks like you just forgot to put your function name in action property of the button in the ui designer. ie button_action.

Guys, tkinter can't be used in Pythonistia. Tkinter is for desktop ui's not mobile. Pythonistia comes with a ui module. You use this to make a GUI in Pythonistia. Its very good. There also is a ui designer. If you select 'UIFile' when creating a new file, once its created you will see you are in the UI Designer. You can also do in code, have a look at the UI module in the docs

@nerdtron , no problems. I think for this example that flex would be the best and easiest. However, when I tried doing it, I had a brain freeze! Its been a long time since I have done it. Pls dont take that as it is hard to do. Once you have it in your head, normally its simple.
I am sure someone else here will chime in with the correct way to set the flex settings.

The example I have put below is still a good a good way to know. Its using a custom view. One of the callbacks you get when you have a Custom View Class is layout. Its called by the ui automatically (if you have a method called layout) when you need to respond to changes in your views height or width. Its worth having a read through the docs about Custom Views.
They are easy to make and give you a lot more flexibility and some extra functionality.

Anyway, I hope this also helps

import ui

class MyClass(ui.View):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # create the field and button
        self.in_fld = ui.TextField()
        self.post_btn = ui.Button(title='Add Item',
                                  bg_color='orange',

        This method is called by the ui automatically when required,
        such as orientation change.

        self.in_fld.width = self.width - self.post_btn.width - 6

@nerdtron, I think the below gives you what you want. I didn't try and get your flex values correct. If you look in the ui.designer, this will help get the settings correct. But you still need to size and position your ui objects for flex to work. Hope it helps.
Also the + 2 and +4 etc in the code is for some margins between the view frame and the ui objects.

import ui

view = ui.View()
view.name = 'test UI'
view.background_color = 'black'

r = ui.Button(title='Add Item', bg_color='orange',
              width=100, height=100, corner_radius=6)
r.size_to_fit()          # resizes the button, but a little tight
r.width += 4             # add a few extra pixels

# using get_window_size()[0], could use ui.get_screen_size()[0]
# get_window_size should work on split screens also
r.x = ui.get_window_size()[0] - r.width - 2 # returns a tuple (w,h)
r.y = 2
#r.background_color = 'orange'
#r.flex = 'BL'
view.add_subview(r)

s = ui.TextField(width=r.frame.min_x - 4,
                 height=r.height)
s.x = 2
s.y = 2
#s.flex = 'BR'
view.add_subview(s)
s.begin_editing()        # This gets the text field ready for input.
                         # You can comment this out, if you dont want
                         # it to behave like this
view.present('fullscreen')

This is only a stab in the dark. But often when I have had problems with something that works some of the time and not other times. The answer is normally relates to timing, ui/blocking etc.
So using the @ui.in_background decorator could help with the ui blocking, sometimes calling time.sleep(1) can help. As I say I am guessing, but I recognise the general pattern of sometimes this works other times it does not from the problems I have had. A ui blocking or timing issue. Hope it helps, I know others here could be more concise to the exact problem, maybe this is enough food for thought.
