Looking for a way to identify the inline code text in a Markdown widget when clicked

[jspv]

My use case is I make heavy use of Markdown widgets to display output from LLM agents. When the user clicks on the widget, I copy the text in the widget to the clipboard to allow it to be pasted elsewhere. This works well, but is problematic when I only want to grab a code block, not the surrounding commentary.

New Goal

I'm trying to make this smarter and to detect if within the Markdown widget, they clicked within a inline code block and if so, only copy the text of the code block. I looking for help with good strategies to accomplish this.

From the Textual code, I see that the Markdown widget will use an internal MarkdownFence widget which contains the code block. What might be a good approach? I'm thinking of:

• registering an on_click message for MarkdownFence; this seems easiest but since this widget type is private to Markdown, seems like it would be a fragile solution
• get the x,y coordinates from the mouse click and traverse down the widget children and see if I can locate the right widget (content_region attribute?) - this also seems feasible but a bit more complicated.

Better ideas?

Thanks!

I would probably just check if the click event for a MarkdownFence, even if this widget is internal it does seem the simplest way!

from textual import events
from textual.app import App, ComposeResult
from textual.widgets import Markdown
from textual.widgets._markdown import MarkdownFence

MARKDOWN = """
# Example Markdown

This is a code block:

```python
def add(a, b):
    return a + b
```
"""


class ExampleApp(App):
    def compose(self) -> ComposeResult:
        yield Markdown(MARKDOWN)

    def on_click(self, event: events.Click) -> None:
        widget = event.widget
        if widget is None:
            return
        if isinstance(widget.parent, MarkdownFence):
            self.notify(widget.parent.code)


if __name__ == "__main__":
    app = ExampleApp()
    app.run()
