.Net] 버튼 Pressed Event!!

 버튼 -> 누르고 있으면 이벤트 발생 ~

 

클릭과는 다른 동작을 함.

 

 

# 차이는 다음과 같음.

 

  void jsfW_Button1_MouseUp(object sender, MouseEventArgs e)
        {
            jsfW_Button1.ForeColor = Color.Black;
        }

  

// 버튼을 누른체 1초후 발생 -> Click Event 는 건너뜀.

  void jsfW_Button1_MousePressing(object sender, EventArgs e)
        {     

             jsfW_Button1.ForeColor = Color.Red;
             label1.Text += "Press" + Environment.NewLine;       
        }

   void jsfW_Button1_MouseDown(object sender, MouseEventArgs e)
        {
            jsfW_Button1.ForeColor = Color.Black;
        }

  

  void jsfW_Button1_Click(object sender, EventArgs e)
        {
            label1.Text += "클릭"+ Environment.NewLine;
        }
