本文實例中的自界說類PictureBox繼續於UserControl,終究完成簡略的分屏功效。分享給年夜家供年夜家參考之用。詳細完成代碼以下:
public partial class PictureControl : UserControl { public event MouseEventHandler PicControl_DoubleClick; private int picNum; /// <summary> /// 屏幕個數 /// </summary> public int PicNum { get { return picNum; } set { if (value == 4 || value == 6 || value == 9 || value == 12 || value == 16 || value == 20 || value == 25)//只能 是4、6、9、12、16、20、25 { 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> /// 依據個數結構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.SetPictureBox(3, 3, size); break; case 12: this.SetPictureBox(3, 4, size); break; case 16: this.SetPictureBox(4, 4, size); break; case 20: this.SetPictureBox(4, 5, size); break; case 25: this.SetPictureBox(5, 5, size); break; } } /// <summary> /// 結構pictureBox /// </summary> /// <param name="x">幾行</param> /// <param name="y">幾列</param> /// <param name="size">以後控件的年夜小</param> private void SetPictureBox(int x, int y,Size size) { int num = 0; for (int i = 0; i < x; i++) { for (int j = 0; j < y; j++) { PictureBox pic = new PictureBox(); pic.SizeMode = PictureBoxSizeMode.Zoom; //設置主動縮放 pic.BackColor = Color.White; //設置配景色彩 pic.Location = new Point((size.Width / y) * j, (size.Height / x) * i); //設置Location pic.BorderStyle = BorderStyle.FixedSingle; //設置邊框 pic.MouseDoubleClick += new MouseEventHandler(pic_MouseDoubleClick); //定閱控件雙擊事宜 pic.Size = new Size(size.Width / y, size.Height / x); //設置控件年夜小 pic.Tag = num; //設定控件編號即屏幕序號 this.Controls.Add(pic); //添加 num++; } } } void pic_MouseDoubleClick(object sender, MouseEventArgs e) { if (this.PicControl_DoubleClick != null) { this.PicControl_DoubleClick(sender, e);//將靜態添加的控件的雙擊事宜 傳向控件體外。 } } private void PictureControl_SizeChanged(object sender, EventArgs e) { this.SetPictureBox(this.picNum); } private PictureBox GetPicByIndex(int index) { foreach (Control c in this.Controls) { if (Convert.ToInt32(c.Tag) == index) { return (PictureBox)c; } } PictureBox p = new PictureBox(); p.Tag = -1; return p; } /// <summary> /// 依據屏幕序號設置圖象 /// </summary> /// <param name="index">屏幕號</param> /// <param name="img">圖象</param> public void SetImageByIndex(int index, Image img) { GetPicByIndex(index).Image = img; } }
