Winform 按键组合键

 

 

 

设置属性KeyPreview 为True 和form的keydown事件

private void FormMain_KeyDown(object sender, KeyEventArgs e)
{
if (e.Modifiers == Keys.Alt)
{
switch (e.KeyCode)
{
case Keys.Right://显示右边
IsShowRigth = true;
lvStatus.Visible = true;
break;
case Keys.Left://隐藏右边
IsShowRigth = false;
lvStatus.Visible = false;
break;
case Keys.Enter://开始和结束

break;
case Keys.Escape://退出程序
System.Environment.Exit(0);
break;

}

}
}

 

另一个

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{

switch (keyData)
{

case Keys.Right:

 

break;

case Keys.Left:

 

break;

case Keys.Up://方向键不反应

break;

case Keys.Down:

 

break;

case Keys.Space:

 

break;

case Keys.Enter:

 

break;

}

//return false;//如果要调用KeyDown,这里一定要返回false才行,否则只响应重写方法里的按键.

//这里调用一下父类方向,相当于调用普通的KeyDown事件.//所以按空格会弹出两个对话框

return base.ProcessCmdKey(ref msg, keyData);

}
