VISUAL C ++检测右键点击一个按钮 [英] Visual C++ Detect a Right Click on a Button

问题描述

我有一个程序，我想在按钮上右击做一个完全不同的金额code的。我有code显示的例子一个消息框，但最终它将是一个方法调用每个。我会告诉你在我需要它的上下文。任何及所有关于如何检测鼠标右键将有助于帮助。以下是我有code的片段：

 私人：系统：虚空的button1_Click（系统：对象^发件人，系统:: EventArgs的^ E）{
             字符串^ BUTTONNAME = safe_cast＆LT;按钮^＆GT;（发件人） -  GT;名称;
             safe_cast＆LT;按钮^＆GT;（发件人） -  GT;启用= FALSE;
             如果（/ *插入code这里来检测右击* /）
                 消息框显示::（右键）;
             其他
                 消息框显示::（左击）;
             消息框显示::（BUTTONNAME）;
         }
};
 

解决方案

您可以使用MouseDown事件并检查它是否是正确的。

 无效button1_MouseDown（对象^ / * *发件人/，系统：视窗：形式：MouseEventArgs ^ E）
      {
         //更新鼠标信息鼠标路径
         点mouseDownLocation =点（E-GT＆; X，E＆GT; Y）;
         字符串^ eventString = nullptr;
         开关（E-GT＆按钮）
         {
            案例:: MouseButtons ::左：
               eventString =L;
               打破;            案例:: MouseButtons ::右：
               eventString =R;
               打破;            案例:: MouseButtons ::中东：
               eventString =M;
               打破;            案例:: MouseButtons :: XButton1：
               eventString =X1;
               打破;            案例:: MouseButtons :: XButton2：
               eventString =X2;
               打破;            案例:: MouseButtons ::无：
            默认：
               打破;
         }
        //处理在这里...
      }
 

I have a program where I want a right click on a button to do a completely different amount of code. I have the code display a messagebox for the example, but eventually it will just be a method call each. I'll show you the context in which I need it. Any and all help on how to detect a right click will help. Here's the snippet of code I have:

    private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
             String^ buttonName = safe_cast<Button^>(sender)->Name;
             safe_cast<Button^>(sender)->Enabled = false;
             if(/*Insert Code Here To Detect a right click*/)
                 MessageBox::Show("Right Click");
             else
                 MessageBox::Show("Left Click");
             MessageBox::Show(buttonName);
         }
};

解决方案

You can use the MouseDown event and check if it is right

void button1_MouseDown( Object^ /*sender*/, System::Windows::Forms::MouseEventArgs^ e )
      {
         // Update the mouse path with the mouse information
         Point mouseDownLocation = Point(e->X,e->Y);
         String^ eventString = nullptr;
         switch ( e->Button )
         {
            case ::MouseButtons::Left:
               eventString = "L";
               break;

            case ::MouseButtons::Right:
               eventString = "R";
               break;

            case ::MouseButtons::Middle:
               eventString = "M";
               break;

            case ::MouseButtons::XButton1:
               eventString = "X1";
               break;

            case ::MouseButtons::XButton2:
               eventString = "X2";
               break;

            case ::MouseButtons::None:
            default:
               break;
         }
        //Process Here...
      }
