获取鼠标状态而无法访问MouseEventArgs? [英] Get Mouse State without access to MouseEventArgs?

问题描述

我有一个包含许多控件的表单.我需要检测鼠标是否向下或向上.大多数时候，我没有 MouseEventArgs .

I have a form with many, many controls. I need to detect if the mouse is down or if it's up. Most of the time, I don't have MouseEventArgs.

有没有一种快速简便的方法来判断没有mouseEventArgs的情况下鼠标是否按下?

Is there a quick and easy way to tell if the mouse is down without mouseEventArgs?

是否有替代方法，或者只有这样的方法?:

Is there an alternative, or is something like this the only way?:

foreach (Control c in this.Controls)
{
    c.MouseUp += new MouseEventHandler(globalMouseUp);
    c.MouseDown += new MouseEventHandler(globalMouseDown);
}


bool isMouseUp = true;


private void globalMouseDown(object sender, MouseEventArgs e)
{
    isMouseUp = false;
}

private void globalMouseUp(object sender, MouseEventArgs e)
{
    isMouseUp = true;
}

推荐答案

您可以尝试使用计时器进行检查:

You can try checking with a timer:

private void timer1_Tick(object sender, EventArgs e) {
  this.Text = "Mouse Is " + (Control.MouseButtons == MouseButtons.Left);
}
