void onMouseEvent(CefBrowser browser,
                  int event,
                  int screenX,
                  int screenY,
                  int modifier,
                  int button)

Implement this method to handle mouse events on Windows. The method is called in case of the following events: MOUSE_MOVED, MOUSE_PRESSED, MOUSE_RELEASED and MOUSE_WHEEL for a horizontal wheel movement.

实现此方法以在Windows上处理鼠标事件。在发生以下事件时调用该方法：MOUSE_MOVED，MOUSE_PRESSED，MOUSE_RELEASED和MOUSE_WHEEL用于水平车轮运动。

参数:

browser - The browser generating the event. - 生成事件的浏览器。

event - A mouse event like MouseEvent.MOUSE_MOVED. - MouseEvent.MOUSE_MOVED等鼠标事件。

screenX - The absolute X position on the screen. - 屏幕上的绝对X位置。

screenY - The absolute Y position on the screen. - 屏幕上的绝对Y位置。

modifier - The modifier keys down during event (e.g. Shift, Ctrl). - 修改器在事件期间按下键（例如Shift，Ctrl）。

button - An integer indicating which mouse button state changed. If parameter event is set to MouseEvent.MOUSE_WHEEL, the value of this parameter specifies the rotation indicator (negative value for left scroll and positive value for right scroll). - 一个整数，指示哪个鼠标按钮状态已更改。如果参数事件设置为MouseEvent.MOUSE_WHEEL，则此参数的值指定旋转指示器（左滚动的负值和右滚动的正值）。
