如何捕获事件框上的事件以检测gtk中的鼠标移动? [英] How to capture event on event box to detect mouse movement in gtk?

问题描述

现在，我在 event_box 上有一个 motion_notify_event ，用于跟踪鼠标坐标.仅当我单击 event_box 时，我才能检测到运动，是否有人知道鼠标悬停时如何捕获 event_box 上的事件，所以我不必点击它.谢谢.

Right now I have a motion_notify_event on an event_box to track mouse coordinates. I can detect motion only if I click on the event_box does any one know how I can capture the event on the event_box when the mouse is over so I don't have to click on it. Thanks.

推荐答案

我认为您想听"motion-notify-event" 信号.确保还启用了 GDK_POINTER_MOTION_MASK 标志.

I think you want to listen to the "motion-notify-event" signal. Make sure you also enable the GDK_POINTER_MOTION_MASK flag.
