Example of a C # split-screen control usage

The custom class PictureBox in this example inherits from the UserControl, and finally realizes the simple split screen function. Share it for everyone's reference. The specific implementation code is as follows:

Public partial class Picturecontrol:usercontrol{public event MouseEventHandler Piccontrol_doubleclick;    private int picnum;      <summary>////number of screens///</summary> public int Picnum {get {return picnum;} set {if (value = = 4 | | value = = 6 | | value = = 9 | | value = | | | value = = | | value = = 25)/          /can only be 4, 6, 9, 12, 16, 20, picnum = value; This.        Setpicturebox (This.picnum); } else {this.          Picnum = 12; This.        Setpicturebox (This.picnum);      }}} public Picturecontrol () {this.picnum = 4;      InitializeComponent (); This.    Setpicturebox (This.picnum);    }///<summary>///based on number of layouts PictureBox//</summary>/<param name= "num" ></param> private void Setpicturebox (int num) {this.      Controls.clear (); Size size = this.      Size; Switch (num) {case 4:this. Setpicturebox (2, 2, size);        Break Case 6:this. Setpicturebox (2, 3, size);        Break Case 9:this.

MouseDoubleClick + = new MouseEventHandler (Pic_mousedoubleclick); Subscription control double-click event pic. size = new Size (size. width/y, size.              height/x); Sets the size of the control pic.                                 Tag = num; Sets the control number, which is the screen number this.                             Controls.Add (pic);        Add num++; }}} void Pic_mousedoubleclick (object sender, MouseEventArgs e) {if (this. Piccontrol_doubleclick = null) {this.      Piccontrol_doubleclick (sender, E);//The double-click event of a dynamically added control is passed outside the control body. }} private void Picturecontrol_sizechanged (object sender, EventArgs e) {this.
