Presenting view and console
-
@KalyJupiter , consider the example below. With the beta version of Pythonista, this would be more straight forward as custom Views have an update method. You can set the interval for When the update method is called. It's maybe not 100% fit for what you are doing, but gives a different way to approach it. Hope its helpful
import ui import time # only use this func to create a button for convienience def quick_button(p, title="", **kwargs): # p is the parent view _inset = 60 btn = ui.Button(name='btn', **kwargs) btn.frame = ui.Rect(0, 0, p.width, p.width).inset(_inset, _inset) btn.corner_radius = btn.width / 2 btn.center = p.bounds.center() btn.title = title btn.bg_color = 'cornflowerblue' btn.tint_color = 'white' btn.font = ('Arial Rounded MT Bold', 48) p.add_subview(btn) return btn # Create a Custom ui.View, Inherit from ui.View class MyClass(ui.View): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # if on the beta version update_interval sets the freq that the update # method is called. self.update_interval = 0 self.tf = None self.make_view() self.run() def make_view(self): btn = quick_button(self, title='OK', action=self.my_btn_action) tf = ui.TextField(width=self.width) self.add_subview(tf) self.tf = tf @ui.in_background def run(self): k = 0 while True: # if the view is not on screen break from the loop if not self.on_screen: break print("### test", k, "###") self.tf.text = "### test {} ###".format(k) k += 1 time.sleep(0.5) # this method does nothing unless you have the beta version of Pythonista. # but the run method would not be needed. def update(self): self.tf.text = "### test {} ###".format(k) def my_btn_action(self, sender): print('do something here') if __name__ == '__main__': f = (0, 0, 300, 400) v = MyClass(frame=f) v.present(style='sheet')Edit: there are a few small mistakes here if you were using the beta version of Pythonista. The update method is wrong. k should be a member instance of the class and updated in the update method. But it was more just to show the idea. Also the writing to the TextField could be accumulated if you needed, just could make another attr to append to and write the contents to the TextField.
-
that update_interval looks much cleaner :) but I don't have access to the beta, didn't know there was one.
on the other hand I needed the full console because I don't have the screen real-estate for an in-view text box - and then there's the amount of logs I go through when I do check the console…
hiding the view temporarily to check the logs was just what I was looking for :)

@KalyJupiter , ok, I understand. Was not sure of your complete requirements. Sometimes bare bones examples can be misleading, because the implementation can get more complex. Here is a gist That shows the same example, just with the beta in mind. Forget the button code. I just have that as a snippet. So easy for me to use in examples.
Your approach seems fine, but you need to find an elegant solution to exit your loop. The small problem is that ui.ButtonItem is slightly different than other ui elements.
Ui.ButtonItem is not subclassed from ui.View like most of the ui elements. The below snippet shows they are different. So for example, uiButtonItem does not have an on_screen attr.If you search the forum, you will find the beta sign up form. I have no idea before the beta will make it to the App Store version. I have a feeling it wont be too long, but i am just guessing.
import ui print("ui.ButtonItem") print(dir(ui.ButtonItem())) print("\n\nui.Button") print(dir(ui.Button())) -
cheers, I found the beta signup form :)
and I'm not worried about exiting the loop

Hmm, for some reason I thought the console is only shown the first time a particular script prints to it... but maybe I am mistaken.
If you are doing lots of back and forth between console and ui, you might also consider an Overlay. This woeks similar to a popover, but does not disappear when you interact with the console, and can be dragged around, minimized, etc. You can also have multiple Overlays active at the same time.
-
That Overlay class is quite nice :) I'll keep it around for later, but it does have some quirks:
for one, the below crashes when trying to set the .text:
if __name__=='__main__': view = ui.View() view.frame = (0, 0, 240, 240) view.flex = 'WH' view.background_color = 'white' valuefield = ui.TextField() valuefield.frame = (120, 34, 120, 34) valuefield.text = "ana" # ⇒ crashes Pythonista view.add_subview(valuefield) o=Overlay(content=view,parent=AppWindows.root()) -
Hmm, I couldn't reproduce the crash, though to get to run I had to add
nameto view (something I should fix), and also enabled touch so the textfield is active.Can you enable the faulthandler (see @dgelessus's pythonista_startup repo) and let me know exactly what is crashing?
from overlay import Overlay,AppWindows import ui if __name__=='__main__': view = ui.View(name='hello') view.frame = (0, 0, 240, 240) view.flex = 'WH' view.background_color = 'white' valuefield = ui.TextField() valuefield.frame = (120, 34, 120, 34) valuefield.text = "ana" # ⇒ crashes Pythonista view.add_subview(valuefield) o=Overlay(content=view,parent=AppWindows.root()) o.content_view.touch_enabled=True -
@dgelessus awesome scripts :D

mmkay, looks like we need a
@on_main_threadsomeplace. Could you try adding this in front of the init method of Overlay? -
yep, that worked :D I put it on attach
@on_main_thread def attach(self):now that Overlay is awesome for a quick settings screen :)

Using Overlays
My first post to the forum.
Using the Overlay class successfully — added the decorator to the attach function as was mentioned.
@on_main_thread def attach(self): self.parent.addSubview_(self)In my demo file, I have a main image overlay (resizable) and two auxilary image overlays (resizable). Each of the overlays could have any kind of UI elements; just showing images for proof of concept.
I have found that, for each overlay, the following statements must be in the order shown or else the overlay window will not resize.
ooo=Overlay(name='abc', content=vvv, parent=AppWindows.root()) ooo.content_view.border_width=2 vvv.content_mode=ui.CONTENT_SCALE_ASPECT_FITHere is my demo file; provide your own PNG files (foo.png and fooe.png).

@struct_engr, excellent first post.

@struct_engr
Had to register as a new account.
Could not access my old account.
Several recover password attempts did not work.
So my new username is struct_engr_ (added underline character at the end) -
@struct_engr_ , did your recover password attempts result in no email arriving, or was there some other issue?
-
@mikael
each time:
no email arrived ASFAIK
carefully checked spam folder
possible that email hit blacklisted IP addresses
FYI
certain IP addresses blocked because of spam -
@struct_engr_ , I think the problem is that for the past 6 months or so, no emails from this forum get actually sent. Neither the password resets or other notifications. @omz, any chance you could take a look?
