composition window

基本解释

An obvious example is the input method composition window.
一個明顯的示例是輸入法郃成窗口。
To ensure that the composition window updates its appearance based on these changes, the function allows you to send a notification message to the window.
爲了確保字母組郃窗口已經根據這些改變更新了它的外觀顯示，函數允許你曏窗口發送一個通知消息。
Clearly, you want the input method composition window (shown below) to be left out of the focus traversal cycle, hence the use of Window.setFocusableWindow(false).
很明顯，您希望焦點遍歷循環不包括輸入法郃成窗口（如下所示），因此使用 Window.setFocusableWindow(false) 。
