GPUI怎么跨控件传递事件。让另一控件接收事件响应。由于view_a,和view_b都有一层包裹。比如作为dock的child。怎么让btn按钮点击，element_c跟着响应。
1 由于都有一层包裹：mainwindow 不能直接访问view_a和view_b,导致emit subscribe使用不方便。
2 我尝试用windows.dispatch_action也接收不到消息。
GPUI有没有好的方法能够实现？
How to pass events across controls in GPUI and have another control receive and respond to the event. Since both view_a and view_b are wrapped (e.g., as children of a dock), how can we make the btn button click and have element_c respond accordingly?
Due to both being wrapped: mainwindow cannot directly access view_a and view_b, making it inconvenient to use emit and subscribe.
I've tried using windows.dispatch_action but still can't receive the message.
Does GPUI have a good way to achieve this?
