Как сделать форму без полей перетаскиваемой в пользовательскую панель заголовка?

Question

Я создал границы менее форму, используя C#, но мог бы сделать заказ строку заголовка перемещаемым, так что я искать в интернете и нашел этот код:

protected override void WndProc(ref Message m) 
{ 
    base.WndProc(ref m); 
    if (m.Msg == WM_NCHITTEST) 
     m.Result = (IntPtr)(HT_CAPTION); 
} 

private const int WM_NCHITTEST = 0x84; 
private const int HT_CLIENT = 0x1; 
private const int HT_CAPTION = 0x2; 

После применения этого кода можно нажать и перетащить свою форму в каждом дюйме формы, за исключением строки заголовка.

Это хороший пример перемещаемого заголовка.
Это полный пример

using System; 
using System.Drawing; 
using System.Windows.Forms; 

namespace Custom_Title_Bar 
{ 
public partial class MainForm : Form 
{ 
    private PictureBox title = new PictureBox(); // create a PictureBox 
    private Label minimise = new Label(); // this doesn't even have to be a label! 
    private Label maximise = new Label(); // this will simulate our this.maximise box 
    private Label close = new Label(); // simulates the this.close box 

    private bool drag = false; // determine if we should be moving the form 
    private Point startPoint = new Point(0, 0); // also for the moving 

    public MainForm() 
    { 
     this.FormBorderStyle = FormBorderStyle.None; // get rid of the standard title bar 

     this.title.Location = this.Location; // assign the location to the form location 
     this.title.Width = this.Width; // make it the same width as the form 
     this.title.Height = 50; // give it a default height (you may want it taller/shorter) 
     this.title.BackColor = Color.Black; // give it a default colour (or load an image) 
     this.Controls.Add(this.title); // add it to the form's controls, so it gets displayed 
     // if you have an image to display, you can load it, instead of assigning a bg colour 
     // this.title.Image = new Bitmap(System.Environment.CurrentDirectory + "\\title.jpg"); 
     // if you displayed an image, alter the SizeMode to get it to display as you want it to 
     // examples: 
     // this.title.SizeMode = PictureBoxSizeMode.StretchImage; 
     // this.title.SizeMode = PictureBoxSizeMode.CenterImage; 
     // this.title.SizeMode = PictureBoxSizeMode.Zoom; 
     // etc   

     // you may want to use PictureBoxes and display images 
     // or use buttons, there are many alternatives. This is a mere example. 
     this.minimise.Text = "Minimise"; // Doesn't have to be 
     this.minimise.Location = new Point(this.Location.X+5, this.Location.Y+5); // give it a default location 
     this.minimise.ForeColor = Color.Red; // Give it a colour that will make it stand out 
     // this is why I didn't use an image, just to keep things simple: 
     this.minimise.BackColor = Color.Black; // make it the same as the PictureBox 
     this.Controls.Add(this.minimise); // add it to the form's controls 
     this.minimise.BringToFront(); // bring it to the front, to display it above the picture box 

     this.maximise.Text = "Maximise"; 
     // remember to make sure it's far enough away so as not to overlap our minimise option 
     this.maximise.Location = new Point(this.Location.X+60, this.Location.Y+5); 
     this.maximise.ForeColor = Color.Red; 
     this.maximise.BackColor = Color.Black; // remember, we want it to match the background 
     this.maximise.Width = 50; 
     this.Controls.Add(this.maximise); // add it to the form 
     this.maximise.BringToFront(); 

     this.close.Text = "Close"; 
     this.close.Location = new Point(this.Location.X+120, this.Location.Y+5); 
     this.close.ForeColor = Color.Red; 
     this.close.BackColor = Color.Black; 
     this.close.Width = 37; // this is just to make it fit nicely 
     this.Controls.Add(this.close); 
     this.close.BringToFront(); 

     // now we need to add some functionality. First off, let's give those labels 
     // MouseHover and MouseLeave events, so they change colour 
     // Since they're all going to change to the same colour, we can give them the same 
     // event handler, which saves time of writing out all those extra functions 
     this.minimise.MouseEnter += new EventHandler(Control_MouseEnter); 
     this.maximise.MouseEnter += new EventHandler(Control_MouseEnter); 
     this.close.MouseEnter += new EventHandler(Control_MouseEnter); 

     // and we need to do the same for MouseLeave events, to change it back 
     this.minimise.MouseLeave += new EventHandler(Control_MouseLeave); 
     this.maximise.MouseLeave += new EventHandler(Control_MouseLeave); 
     this.close.MouseLeave += new EventHandler(Control_MouseLeave); 

     // and lastly, for these controls, we need to add some functionality 
     this.minimise.MouseClick += new MouseEventHandler(Control_MouseClick); 
     this.maximise.MouseClick += new MouseEventHandler(Control_MouseClick); 
     this.close.MouseClick += new MouseEventHandler(Control_MouseClick); 

     // finally, wouldn't it be nice to get some moveability on this control? 
     this.title.MouseDown += new MouseEventHandler(Title_MouseDown); 
     this.title.MouseUp += new MouseEventHandler(Title_MouseUp); 
     this.title.MouseMove += new MouseEventHandler(Title_MouseMove);   
    } 

    private void Control_MouseEnter(object sender, EventArgs e) 
    { 
     if (sender.Equals(this.close)) 
      this.close.ForeColor = Color.White; 
     else if (sender.Equals(this.maximise)) 
      this.maximise.ForeColor = Color.White; 
     else // it's the minimise label 
      this.minimise.ForeColor = Color.White;    
    } 

    private void Control_MouseLeave(object sender, EventArgs e) 
    { // return them to their default colours 
     if (sender.Equals(this.close)) 
      this.close.ForeColor = Color.Red; 
     else if (sender.Equals(this.maximise)) 
      this.maximise.ForeColor = Color.Red; 
     else // it's the minimise label 
      this.minimise.ForeColor = Color.Red;  
    } 

    private void Control_MouseClick(object sender, MouseEventArgs e) 
    { 
     if (sender.Equals(this.close)) 
      this.Close(); // close the form 
     else if (sender.Equals(this.maximise)) 
     { // maximise is more interesting. We need to give it different functionality, 
      // depending on the window state (Maximise/Restore) 
      if (this.maximise.Text == "Maximise") 
      { 
       this.WindowState = FormWindowState.Maximized; // maximise the form 
       this.maximise.Text = "Restore"; // change the text 
       this.title.Width = this.Width; // stretch the title bar 
      } 
      else // we need to restore 
      { 
       this.WindowState = FormWindowState.Normal; 
       this.maximise.Text = "Maximise"; 
      } 
     } 
     else // it's the minimise label 
      this.WindowState = FormWindowState.Minimized; // minimise the form 
    } 

    void Title_MouseUp(object sender, MouseEventArgs e) 
    { 
     this.drag = false; 
    } 

    void Title_MouseDown(object sender, MouseEventArgs e) 
    { 
     this.startPoint = e.Location; 
     this.drag = true; 
    } 

    void Title_MouseMove(object sender, MouseEventArgs e) 
    { 
     if (this.drag) 
     { // if we should be dragging it, we need to figure out some movement 
      Point p1 = new Point(e.X, e.Y); 
      Point p2 = this.PointToScreen(p1); 
      Point p3 = new Point(p2.X - this.startPoint.X, 
           p2.Y - this.startPoint.Y); 
      this.Location = p3; 
     } 
    } 
} // end of the class 
} // end of the namespace 

Если вы хотите, вы можете извлечь только движущаяся код и интегрировали его с кодом, подвижный код Title только в следующем обработчики событий

• Title_MouseUp

• Title_MouseDown

• Title_MouseMove
