More minimal frame title?

[JDeeth]

Frame formats like this:

┌─| Hello |─┐
│World      │
└───────────┘

Is there a straightforward way to draw a frame without the padding round its title?

┌───Hello───┐
│World      │
└───────────┘

Code for the above:

from prompt_toolkit.application import Application
from prompt_toolkit.layout import Layout, VSplit, Window
from prompt_toolkit.key_binding import KeyBindings
from prompt_toolkit.key_binding.bindings.named_commands import end_of_file
from prompt_toolkit.widgets import Frame, TextArea

kb = KeyBindings()
kb.add("c-c")(end_of_file)

frame = Frame(TextArea(text="World", width=11), title="Hello")
root_container = VSplit([frame, Window()])
layout = Layout(root_container)

app = Application(layout=layout, key_bindings=kb)
app.run()

I don't think the Frame widget has a way to achieve that using its constructor.

However, the Frame class is defined in src/prompt_toolkit/widgets/base.py .
It's only 96 lines long and pretty easy to understand. You could either subclass it and override the "top_row_with_title" attribute, or just copy and paste the class and modify it to your liking.

I will probably do the same at some point because I want to be able to change the border characters to use double borders, which also isn't supported with the builtin widget. The thin border characters are hard-coded at the module level.
