描述

Describe the bug

Under GTK, If a readonly text input loses focus as a result of keyboard input (i.e., pressing tab), a beep is emitted.

Steps to reproduce

  1. Run Tutorial 1
  2. Type Tab twice

A beep will be emitted when the Celsius field loses focus.

Expected behavior

No beep should be emitted.

Screenshots

No response

Environment

  • Operating System: Ubuntu 22.04
  • Python version: All
  • Software versions:
    • Toga: 0.4.2+

Logs

Additional context

No beep is emitted on loss of focus.

It's arguable whether the readonly widget should be able to accept focus at all - that's the behavior on macOS. If this is acceptable, calling native.set_can_focus() as part of set_readonly() might be a fix for this.

There is likely similar issues on any other widget with a clear input focus and a readonly option.

研究方向
Investigate the GTK backend widget implementation, specifically the `set readonly()` method. Look at how other read only widgets handle focus. Consider calling `native.set can focus(False)` in `set readonly()` to prevent focus entirely, as suggested in the issue. Also examine if other widgets with readonly option have similar issues. Check the relevant source file in `src/gtk/toga gtk/widgets/` for the text input implementation.
