如何修复事件延迟

问题描述

我正在为一个学校项目制作一个餐桌预订系统，并且我正在使用一个 PictureBox 列表来表示这些餐桌.这些 PictureBoxes 我已经链接了一个悬停事件，当我悬停时，BackColor 属性发生了变化.

I'm making a table reservation system for a school project, and I'm using a list of PictureBoxes to represent the tables. To these PictureBoxes I have linked a hover event, and when I hover the BackColor property is changed.

List<PictureBox> pb = new List<PictureBox> { pictureBox1, pictureBox2, pictureBox3};

foreach (PictureBox p in pb)
{
    p.BorderStyle = BorderStyle.Fixed3D;
    p.BackColor = Color.White;
    p.MouseHover += new EventHandler(mouseOn);
}

private void mouseOn(object sender, EventArgs e)
{
    ((PictureBox)sender).BackColor = Color.Green;
}

一切都很好，除了当我将鼠标悬停在事件触发前需要 1 秒，有什么方法可以立即触发事件?

Everything works great, except that when I hover the mouse over, it takes 1 second before the event is triggerd, is there any way to trigger the event immidiately?

推荐答案

如果要立即触发事件，请改用 MouseEnter 事件.根据设计，您的鼠标应保持静止一段时间以触发 MouseHover 事件.

If you want to trigger event immediately, use MouseEnter event instead. By design your mouse should stay stationary for some time for MouseHover event to fire.

BTW SystemInformation.MouseHoverTime 保存 MouseHover 事件的延迟.

BTW SystemInformation.MouseHoverTime holds that delay for MouseHover event.
