设置readonly的TextEntry能否通过代码修改？readonly仅限制GUI用户操作？

Great questions—let's unpack each one step by step:

1. Can you modify TextEntry.text via code when the readonly property is set? #

Absolutely! The readonly property is only meant to block user interactions through the GUI (like typing, pasting, or deleting text with the keyboard/mouse). From code, you can directly assign a new value to the text property without any restrictions. For example:

# This works even if readonly=True
my_text_entry.text = "Updated content from code"

2. Can you use TextEntry.insert_text() on an output-only, readonly=True TextEntry? #

Generally, no. Methods like insert_text() are designed to simulate user-driven input actions—and since readonly=True (plus output-only) explicitly blocks user-initiated changes, most GUI frameworks will prevent this method from modifying the text.

That said, you can still update the content by directly setting the text property, as mentioned in the first question. The restriction only applies to methods that mimic user interaction.

3. Does the readonly property only affect GUI user operations? #

Exactly! This is the core purpose of the readonly attribute. It's a guardrail to prevent end-users from altering the text through the interface, but it doesn't restrict your code from modifying the underlying value. You're free to update the text programmatically whenever needed, regardless of the readonly setting.
