C++/Cli里重载winform的WndProc和ProcessCmdKey

注意，ProcessCmdKey里的第二个参数，不能用%

不过看WndProc和ProcessCmdKey在C#上的定义，看不出System::Windows::Forms::Keys keyData居然不需要%

看看vs里面对象浏览器里的定义：

public ref class SelectEntityToolForm : public System::Windows::Forms::Form
{
protected: virtual System::Void WndProc(System::Windows::Forms::Message% msg)override;
virtual System::Boolean ProcessCmdKey(System::Windows::Forms::Message% msg, System::Windows::Forms::Keys keyData) override;
};



System::Void SelectEntityToolForm::WndProc(System::Windows::Forms::Message% m)
    {
        __super::WndProc(m);
        //BeConsole::Printf();
        
        if (m.Msg == 0x0018) // WM_SHOWWINDOW
        {
            if (m.WParam.ToInt32() == SW_HIDE)
            {
                int i = 0;
                std::ignore = i;
                // 窗体被隐藏时的处理代码
                // ...
                //System::Windows::Forms::MessageBox::Show("选择对话框被隐藏");
            }
            else if (m.WParam.ToInt32() == SW_SHOWNORMAL)
            {
                //System::Windows::Forms::MessageBox::Show("选择对话框被显示");
            }
            else
            {
//                 auto x = m.WParam.ToInt32();
//                 std::ignore = x;
//                 std::wstring str = fmt::format(L"WM_SHOWWINDOW {}", x);
// 
//                 System::Windows::Forms::MessageBox::Show(gcnew System::String(str.c_str()));
            }
        }
    }

    System::Boolean SelectEntityToolForm::ProcessCmdKey(System::Windows::Forms::Message% msg, System::Windows::Forms::Keys keyData)
    {
        // 检查是否按下了特定的键
        if (keyData == System::Windows::Forms::Keys::Escape)
        {
            MiscUtil::ScheduleStopCurrentCommand();
            this->Hide();
            return true; // 表示键被处理了
        }

        // 如果不是F1键，则调用基类的ProcessCmdKey方法继续处理
        return System::Windows::Forms::Form::ProcessCmdKey(msg, keyData);
    }
