When the mouse cursor is moved to the button, as the **onMouse** event bubbles up by default, both the **onMouse** callbacks of the **\<Column>** and **\<Button>** components are invoked. In this process, the mouse cursor moves, but no mouse button is clicked. Therefore, in the displayed information, the value of **button** is 0 (enumerated value of **MouseButton.None**) and the value of **action** is **3** (enumerated value of **MouseAction.Move**). 1.
