Two issues:
1. When I try to create a custom view with the pyui I am unable to created rounded corners, but if instead I create the custom view without the pyui I get rounded corners.
2. When I try to use font in a custom view the text is not bold.

How do I solve this? Thanks for any help!

Here is an example that illustrates both:
```python
import ui

class customButton(ui.View):
def init(self,frame=(0,0,300,100)):
self.corner_radius = 8
self.frame = frame
self.text = 'why does only one of these have rounded corners and neither have bold text?'

def draw(self):
path = ui.Path.rounded_rect(0,0, self.width,self.height,self.corner_radius)
ui.set_color('green')
path.fill()
ui.draw_string(self.text,(0,0,self.width,self.height),('',20),'black',ui.ALIGN_CENTER)

the pyui file consists of a single custom view, with

x=20

y=200

width=300

height=100

custom view class = customButton

v = ui.load_view()
cbn = customButton()
v.add_subview(cbn)
v.present('fullscreen')

First, when you post a source code, please insert it between 2 lines of 3 back ticks.
When you edit your post, the `````` key does it for you, try it.

That works

You're right, I don't know why but try this font, it works

        ui.draw_string(self.text,(0,0,self.width,self.height),('Arial Rounded MT Bold',20),'black',ui.ALIGN_CENTER)

Or, in place of draw, use a label, there bold works 😉

    def __init__(self, frame=(20,200,300,100)):

        self.corner_radius = 8
        self.frame = frame
        self.text = 'why does only one of these have rounded corners and neither have bold text?'
        l = ui.Label()
        l.frame = (0,0,self.width,self.height)
        l.background_color = 'green'
        l.text_color = 'black'
        l.number_of_lines = 0
        l.text = self.text
        l.font = ('<System-bold>',20)
        self.add_subview(l)

@peiriannydd Finally, you didn't say if this solved your two problems...

Yes, thank you, this solved my problems, although using a label since doesn’t work with ui.draw_string seems like a bug workaround.

@peiriannydd Said

seems like a bug workaround.

Sure, but what else to do if the app is no more updated?

@peiriannydd other workaround

        f = '<System>'
        ui.draw_string(self.text,(0,0,self.width,self.height), (f,20), 'black',ui.ALIGN_CENTER)
        ui.draw_string(self.text,(1,1,self.width-1,self.height-1), (f,20), 'black',ui.ALIGN_CENTER)

So, a way that should work would be to use UIFont to find the system font name, and then create a bold version, then find the name of that... Just an idea, have not pursued it yet

@JonB I did try:

<UICTFont: 0x103990c70> font-family: ".SFUI-Semibold"; font-weight: bold; font-style: normal; font-size: 20.00pt

Try

".SFCompactText-Bold"

Or

".SFProText-Bold"

Also-- the "Text" part of the name can be replaced with Rounded, or Display. Apparently Text is supposed to used under 19pt, Display for 20pt+. I'm not sure what Rounded is for -- looks a little more informal.

I think apple tried to obfuscate system font names so people used their new API in iOS13, to prevent people hard coding fonts that might change later. Hence reason that .SFUI doesnt work

I assume draw_string is using UIFont.fontWithName_size_

I think compact is for watchOS, Pro for iOS.

Does UIFont have a .fontName() method?

@JonB neither ".SFProText-Bold" nor ".SFProDisplay-Bold" do work

I ask me if for SF standard system font, bold in name does work without a supplementary bold attribute

@JonB said

Yes

@peiriannydd this works, in place of ui.draw_string

        UIFont = ObjCClass('UIFont').boldSystemFontOfSize_(20.0)        
        attrtext = ObjCClass('NSMutableAttributedString').alloc().initWithString_(ns(self.text))
        attrtext.addAttribute_value_range_(ns('NSFont'), UIFont, NSRange(0,len(self.text)))     
        attrtext.drawInRect_(CGRect(CGPoint(0, 0), CGSize(self.width, self.height)))
