无法访问MouseEventArgs获取鼠标状态？

Question

我有一个包含许多控件的表单.我需要检测鼠标是否已关闭或是否已启动.大多数时候,我没有MouseEventArgs.

有没有mouseEventArgs可以快速简便地判断鼠标是否已关闭？

有替代方案,还是这样的唯一途径？:

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;
}

Answer 1

您可以尝试使用计时器进行检查:

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

Answer 2

检查 Control.MouseButtons 静态属性：

if (Control.MouseButtons == MouseButtons.Left)
{
}
