Presenting view and console

KalyJupiter

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())

JonB

Hmm, I couldn't reproduce the crash, though to get to run I had to add name to 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

KalyJupiter

@dgelessus awesome scripts :D
@JonB the above main body I placed in overlay.py and simply ran the file ( after correcting the name issue )

mmkay, looks like we need a @on_main_thread someplace. Could you try adding this in front of the init method of Overlay?

KalyJupiter

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_FIT

Here is my demo file; provide your own PNG files (foo.png and fooe.png).

from overlay import Overlay, AppWindows
from gestures import Gestures
import ui

if __name__=='__main__':
    
    iv0=ui.ImageView(frame=(0,0,300,300))
    iv0.image=ui.Image.named('test:Peppers')
    iv0.name='OMAIN▪️'
    
    iv1=ui.ImageView(frame=(0,0,200,200))
    iv1.image=ui.Image.named('foo.png')
    iv1.name='ICR▪️'
    iv1.alpha=1
    overlay1=Overlay(content=iv1,parent=AppWindows.root())
    overlay1.content_view.border_width=2
    iv1.border_width=1
    iv1.content_mode=ui.CONTENT_SCALE_ASPECT_FIT
    
    iv2=ui.ImageView(frame=(0,0,200,200))
    iv2.image=ui.Image.named('fooe.png')
    iv2.name='E▪️'
    iv2.alpha=1
    overlay2=Overlay(content=iv2,parent=AppWindows.root())
    overlay2.content_view.border_width=2
    iv2.border_width=1
    iv2.content_mode=ui.CONTENT_SCALE_ASPECT_FIT
    
    omain=Overlay(name='abc', content=iv0, parent=AppWindows.root())
    omain.content_view.border_width=2
    iv0.border_width=1
    iv0.content_mode=ui.CONTENT_SCALE_ASPECT_FIT

@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)

mikael

@struct_engr_ , did your recover password attempts result in no email arriving, or was there some other issue?

struct_engr_

@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

mikael

@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?
