myMouseEvent.rar_qt 鼠标
在Qt中,mouseMoveEvent是一个事件处理函数,用于处理鼠标移动事件。当鼠标在窗口上移动时,该函数会被触发。在MainWindow类中,你可以重写mouseMoveEvent函数来自定义对鼠标移动事件的处理。在重写的mouseMoveEvent函数中,你可以获取鼠标的坐标,并进行相应的操作。例如,你可以使用获取到的坐标来判断鼠标是否在某个区域内,然后执行相应的逻辑。在重写的mouseMoveEvent函数中,你可以通过e->x()和e->y()来获取鼠标的当前坐标。然后,你可以使用这些坐标来进行相关的判断和操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
