C#按住鼠标事件 [英] C# Hold down mouse event

问题描述

我有一个mousemove事件，它获取光标的位置并将其输出到两个标签(X和Y)，当我将鼠标悬停时，该值会动态变化.我有一个mousedown事件，单击该事件时，会将相同的值输出到文本框.如何合并mousedown和mousemove事件，以便在悬停并按住鼠标按钮时，文本框的值会随着移动而动态变化.

I have a mousemove event that takes the position of the cursor and outputs it to two labels (X and Y), the value dynamically changes as I hover around. I have a mousedown event that when clicked, the same values are outputted to a textbox. How can I combine the mousedown and mousemove events so that when I hover AND hold down the mouse button, the textbox value dynamically changes as I move.

推荐答案

您可以在Move事件处理程序中查询鼠标按钮，即:

You can interrogate the mouse buttons in your Move event handler, i.e. :

void Form1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left) {
        String tipText = String.Format("({0}, {1})", e.X, e.Y);
        trackTip.Show(tipText, this, e.Location);
    }
}
