@mikael no Problem ;)

i Have an Question about the UI constraints..

When i use Buttons with corner radius = 50 my text is cutted.....
i tried to fix this with the Width... but it didn't worked.....

[JonB]

you could probably change horizontal alignment to center. i think the right way to do it would be to adjust the

contentEdgeInsets

objc attribute of the underlying uibutton, to allow at least the edge radius amount of inset in left and right sides (or maybe edge radius divided by sqrt(2) on all 4 sides).

[DavinE]

@JonB thanks for the fast reply but i understand nothing.. :(

do you have an example for me where i can see what your mean ?

an other Thing what i don't understand is when i use for example the dock element top_center at 2 Buttons its overlapping

how can i fix this.....

thanks for your help!

@DavinE, can you share a small example of your problem case?

[JonB]

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.

@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.

[mikael]

@DavinE, if you use dock top_center on two buttons, their top centers will be placed in the same place and they will overlap.

If you want them one above the other, you can still dock both top_center, and then adjust the second view as follows:

at(second).top = at(first).bottom

i'll Show you tomorrow or on the Weekend my Examples for my two Problems

Yes Thats My issue...
They will overlap....

I will have a Look at this in the Weekend.

Short and stupid Question:
First second are my two Buttons ??

Thanks a looooot for the great help here!!

Yes, just example names.

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 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

[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
