本文将介绍在C++/CLI中如何使用Windows Forms更改按钮发件人的文本。首先需要说明,C++/CLI是C++语言和CLI(Common Language Infrastructure)平台的结合,CLI是一个面向对象的框架,提供了对C++、C#、VB等语言的支持。
在Visual Studio中创建一个C++/CLI Windows Forms应用程序,命名为“ChangeButtonText”。
在Form1.h头文件中添加一个按钮。在Form1的构造函数中,设置按钮的文本为“发送”。
private: System::Windows::Forms::Button^ buttonSend;
public:
Form1(void)
{
InitializeComponent();
//
// buttonSend
//
this->buttonSend = (gcnew System::Windows::Forms::Button());
this->buttonSend->Location = System::Drawing::Point(12, 12);
this->buttonSend->Name = L"buttonSend";
this->buttonSend->Size = System::Drawing::Size(75, 23);
this->buttonSend->TabIndex = 0;
this->buttonSend->Text = L"发送";
this->buttonSend->UseVisualStyleBackColor = true;
this->buttonSend->Click += gcnew System::EventHandler(this, &Form1::buttonSend_Click);
this->Controls->Add(this->buttonSend);
}
在Form1.h头文件中添加一个文本框。在Form1的构造函数中,设置文本框的位置、大小和默认文本为“发件人”。
private: System::Windows::Forms::TextBox^ textBoxSender;
public:
Form1(void)
{
InitializeComponent();
//
// buttonSend
//
this->buttonSend = (gcnew System::Windows::Forms::Button());
this->buttonSend->Location = System::Drawing::Point(12, 12);
this->buttonSend->Name = L"buttonSend";
this->buttonSend->Size = System::Drawing::Size(75, 23);
this->buttonSend->TabIndex = 0;
this->buttonSend->Text = L"发送";
this->buttonSend->UseVisualStyleBackColor = true;
this->buttonSend->Click += gcnew System::EventHandler(this, &Form1::buttonSend_Click);
this->Controls->Add(this->buttonSend);
//
// textBoxSender
//
this->textBoxSender = (gcnew System::Windows::Forms::TextBox());
this->textBoxSender->Location = System::Drawing::Point(93, 14);
this->textBoxSender->Name = L"textBoxSender";
this->textBoxSender->Size = System::Drawing::Size(100, 21);
this->textBoxSender->TabIndex = 1;
this->textBoxSender->Text = L"发件人";
this->Controls->Add(this->textBoxSender);
}
在Form1的源文件Form1.cpp中,实现按钮点击事件的处理函数buttonSend_Click。在该函数中,获取文本框的内容,并将其设置为按钮的文本:
private: System::Void buttonSend_Click(System::Object^ sender, System::EventArgs^ e) {
String^ senderText = this->textBoxSender->Text;
this->buttonSend->Text = senderText;
}
编译并运行程序,单击按钮,可以看到按钮上的文本会变成文本框中输入的内容。
本文介绍了使用C++/CLI和Windows Forms更改按钮发件人文本的步骤。这只是一个简单的示例,C++/CLI和Windows Forms还有很多功能和用法等待您去探索。
