[英]Capture spacebar press to pause Timer C#
I have a windows form which is a countdown Timer.我有一个 windows 表格,它是一个倒数计时器。 What is the best way for me to pause the timer by pressing the spacebar on the keyboard.通过按键盘上的空格键来暂停计时器的最佳方法是什么? I have three buttons on the form for start, pause and stop and res-set.我在表单上有三个按钮,用于开始、暂停和停止以及重新设置。 However I also want to pause, restart on press off spacebar.但是我也想暂停,按下空格键重新启动。 I tried to add a fourth button and then made it hidden on the form and added the following code (changed the EventArgs to KeyEventArgs:我尝试添加第四个按钮,然后将其隐藏在表单上并添加以下代码(将 EventArgs 更改为 KeyEventArgs:
private void button1_Click(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Space)
// Pause the timer.
timer1.Enabled = false;
paused = true;
Start.Enabled = true;
Pause.Enabled = false;
}
However when i try to run this i get the error - No overload for 'button1_Click matches delegate System.EventHandler但是,当我尝试运行它时,我得到了错误 - 'button1_Click 没有重载匹配委托 System.EventHandler
Is there something I have missed or a better way off doing this.有什么我错过的或更好的方法吗?
Any Help/Advice would be appreciated.任何帮助/建议将不胜感激。
The Click
event doesn't take a KeyEventArgs
. Click
事件不需要KeyEventArgs
。
You're looking for the form's KeyPress
event.您正在寻找表单的KeyPress
事件。
