示例
下面的代码示例使用构造函数之 ControlPaint 一来绘制平面 Button 控件。
#using <System.dll>
#using <System.Drawing.dll>
#using <System.Windows.Forms.dll>
using namespace System;
using namespace System::Drawing;
using namespace System::Windows::Forms;
public ref class Form1: public Form
{
private:
Button^ button1;
Button^ button2;
public:
Form1()
{
button1 = gcnew Button;
button2 = gcnew Button;
this->button2->Location = Point(0,button1->Height + 10);
this->Click += gcnew EventHandler( this, &Form1::button2_Click );
this->Controls->Add( this->button1 );
this->Controls->Add( this->button2 );
}
private:
void button2_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Draws a flat button on button1.
ControlPaint::DrawButton( System::Drawing::Graphics::FromHwnd( button1->Handle ), 0, 0, button1->Width, button1->Height, ButtonState::Flat );
}
};
[STAThread]
void main()
{
Application::Run( gcnew Form1 );
}
using System;
using System.Drawing;

{
Application.Run(new Form1());
}
public Form1()
{

this.Click += Button2_Click;
this.Controls.Add(_button1);
this.Controls.Add(_button2);
}
private void Button2_Click(object sender, System.EventArgs e)
{
// Draws a flat button on button1.

注解
类中包含的 ControlPaint 方法使你能够绘制自己的控件或控件的元素。 如果 UserPaint 控件的位设置为 true ，则可以控制自己的控件的绘制。 可以通过调用 GetStyle 或 SetStyle 方法获取或设置样式位。 可以为任何控件设置多个样式位。 枚举 ControlStyles 成员可以与按位运算组合使用。
