Pythonista View (question)

DavinE

i think this shows the problem, and a potential solution:
import ui
from objc_util import *

v=ui.View(bg_color='white')

b=ui.Button(title='press to resize with insets')

b.border_width=1
b.corner_radius=50

@on_main_thread
def a(sender):
	sender.objc_instance.button().contentEdgeInsets=(0, 50,0, 50) #t,l,b,r
	sender.size_to_fit()

b.action=a

v.add_subview(b)
v.present()
The height changes when using this method, so i assume that those edgeinsets are overriding some other sort of anchor or layout constraint that i don't get.

thats a good example...
but is it Possible to set the size at begin ?
not over an action....

is this example okay to do this so ?:

import ui
from objc_util import *

v=ui.View(bg_color='white')

b=ui.Button(title='press to resize with insets')

b.border_width=5
b.corner_radius=50
b.objc_instance.button().contentEdgeInsets=(5, 50,5, 50)
b.size_to_fit()

v.add_subview(b)
v.present()

@JonB, sorry to be thick, but I still do not understand what the problem is or what the insets are for. In the example above I used corner radius to create buttons with rounded ends, but this must be about something else.

My Problem is when i use border_width and border_radius my text is cutted by the Button...
@JonB understand my Problem correctly

@DavinE, inspired by your question, I uploaded a new version with an attach option with these functions:

above
below
left_of
right_of

With those, your use case could also be:

dock(first).top_center(superview)
attach(second).below(first)

Great :D how can i Update my files ?
over stash ?

mikael

@DavinE, pip update pythonista-anchors

DavinE

oh man..... i'm so stupid :D

ty @mikael

@DavinE, don’t be hard on yourself. Just remember you have the -h option for most stash commands, like pip -h.

DavinE

Thanks @mikael for that great Support here Thumbs Up

Hay @mikael,

i Think i found an issue in the attach function:

xxx.../site-packages-3/anchors/core.py:780: ConstraintWarning: Probably missing superview
  at(self.view).left = at(other).right
xxx.../site-packages-3/anchors/core.py:801: ConstraintWarning: Probably missing superview
  getattr(anchor_at, prop) + modifier)
Traceback (most recent call last):
  File "_ctypes/callbacks.c", line 234, in 'calling callback function'
  File "xxx..../Pythonista3.app/Frameworks/Py3Kit.framework/pylib/site-packages/objc_util.py", line 1066, in OMMainThreadDispatcher_invoke_imp
    retval = func(*args, **kwargs)
  File "xxx.../site-packages-3/anchors/core.py", line 213, in on_change
    value_changed = next(constraint.runner)
  File "<string>", line 27, in constraint_runner
AttributeError: 'NoneType' object has no attribute 'bounds'

i get this by:

attach(second).right_of(first)

@DavinE, yes thank you, there was a missing add_subview, now fixed in the version on PyPI.
