what is sphinx ? and kivy rst widget support it ?

Sphinx is a documentation tool. See: https://www.sphinx-doc.org/en/master/

I assume you have an rst document, and you want to embed python code in the rst document.  

see: https://docutils.sourceforge.io/docs/user/rst/quickstart.html#preformatting-code-samples

You could use the kivy CodeInput widget to display python code.  This would provide syntax highlighting.

The rst widget in kivy also responds to the kivy label markup, so you can also use that to change fonts or colors.

You may find these reference documents helpful:

https://docutils.sourceforge.io/docs/user/rst/quickref.html#literal-blocks

To insert code in rst the preceding paragraph needs to end with two colons "::".  The code (the literal block) must be indented.  The indentation is what specifies the literal block.  In the example below I used the textwrap module from the standard library to add a leading tab to the code to create the literal block.

from kivy.app import App
from kivy.lang import Builder

import textwrap

kv= """
BoxLayout:
    orientation: 'vertical'
    Label:
        text: 'RST Code Example'
        size_hint_y: None
        height: dp(30)
    RstDocument:
        id: rst_document
"""

rst_text = """

Code in ReStructuredText
========================

This is **Bold text**, some ``interpreted text``.  This is regular text. This is *italics*.


We put code in a "literal box". We start a literal box by putting "::" in the preceding paragraph.
The literal is indicated by being indented at a level greater than the preceding text.  
When the level of indent is restored, the literal box ends.  

The ReStructuredText documentation provides these directions:
To just include a chunk of preformatted, never-to-be-fiddled-with text, finish the prior paragraph with "::".
The preformatted block is finished when the text falls back to the same indentation level as a paragraph prior
to the preformatted block.

"""

class RstApp(App):
    def build(self):
        return Builder.load_string(kv)

    def on_start(self):
        with open('rst_text.py') as f:
            code = f.read()
        indented_code = textwrap.indent(code, prefix='\t')
        self.root.ids.rst_document.text = f"{rst_text}::\n\n{indented_code}\n\nBack to text"


RstApp().run()

how to change ttf file of text in RstDocument

chnage text color ?

i want to see which feature are supported by RstDocument ?

[ElliotG]

You can use the Label markup in the RstDocument to change color or font inline.  See: https://kivy.org/doc/stable/api-kivy.uix.label.html#markup-text

The RstDocument has a colors dictionary that controls the color of major components.  You can print it out, printing out the colors dictionary from my previous example shows:

self.root.ids.rst_document.colors={'background': 'e5e6e9ff', 'link': 'ce5c00ff', 'paragraph': '202020ff', 'title': '204a87ff', 'bullet': '000000ff'}

If you change the value in the colors dict the corresponding element will change color. 

I would suggest trying the features in the ReStrucuturedText documentation.  If you have trouble, reach out I'll try to help.

see: 

https://docutils.sourceforge.io/rst.html

https://docutils.sourceforge.io/docs/user/rst/quickstart.html

This kind of problem is generally created when a recursive loop is accidently created.  If for example you have a widget where the size is dependent on the parent, and the parent size is dependent on the size of the child it creates a recursive loop. Carefully look thorough your kv code.  You could start commenting out elements until the problem resolves, to help find the root cause.

If you need to select and copy arbitrary text, use a TextInput or CodeInput.  Looking at the source code for RstDocument, the elements are made of labels.  You could use the clipboard to select all of the text.

Another possible approach using the RstDocumet would be to use markup to create refernce tags or anchors and use those to copy text to the clipboard.

Hi,

Need help to make my app bar's corners rounded, I have searched in internet and gpt couldn't find anything. I need my app bar to look like a google search bar but not a search bar ofc.

Thanks,

Siva.

In the future when asking a new question, create a new conversation. 

You can create your own bar (depending on the features you need), or you will need to modify the source code for the kivymd app bar.  Setting the radius of the MDTopAppBar is not a supported feature. 

Here is a quick example just using a Label and canvas to create a rounded rectangle with text.  You could add the CommonElevationBehavior and a Label if you wanted the elevation effect.

from kivymd.app import MDApp
from kivy.lang import Builder

kv = """
MDScreen:
    md_bg_color: self.theme_cls.secondaryContainerColor
   
    Label:
        text: 'Not a real app Bar'
        color: 'black'
        size_hint: .8, None
        padding: dp(10)
        size: self.texture_size
        pos_hint: {'center_x': 0.5, 'center_y': 0.5}
        canvas.before:
            Color:
                rgba: 1, 1, 1, 1
            RoundedRectangle:
                size: self.size
                pos: self.pos
                radius: 30, 30, 30, 30
"""

class RoundedBarApp(MDApp):
    def build(self):
        self.theme_cls.theme_style = "Dark"
        return Builder.load_string(kv)

RoundedBarApp().run()
