Changing the value of a CodeEditor causes all text to be selected #8260
Description
ALL software version info
I am running the example with uv run --with panel==1.8.2 --python=3.12
Description of expected behavior and the observed behavior
When the contents of a code editor widget are updated, the new text is entirely selected. So, if the user touches their keyboard, all of the text is lost. Changing the displayed text should not cause a "select all"
Complete, minimal, self-contained example code that reproduces the issue
This example updates the text in the CodeEditor every 3 seconds. When that happens, all of the text becomes selected.
import panel as pn
import param
pn.extension('codeeditor')
class Editor(param.Parameterized):
def __init__(self, **kwrgs):
self.count = 0
self.editor = pn.widgets.CodeEditor(value="my clock has ticked 0 times")
self.cb = pn.state.add_periodic_callback(self.update_editor, period=3000)
super().__init__(**kwrgs)
def update_editor(self):
self.count += 1
self.editor.value = f"my clock has ticked {self.count} times"
def view(self):
template = pn.template.FastListTemplate(
site="CountTicks",
title="v1",
main=[
pn.Column(self.editor),
],
main_max_width="768px",
)
return template
def get_editor():
editor = Editor()
return editor.view()
# Start server
pn.serve(get_editor, port=9999, websocket_origin="*", verbose=True)Stack traceback and/or browser JavaScript console output
