我尝试创建一类对象（图片框），然后将其称为我的主代码以从不同图片框的菜单中创建其他图片框。我想将它们固定在面板上以绘制 shcema 或组织图。
谢谢
类 _createpicture { public int p; 公共 int p_2;
PictureBox pictureBox2 = new PictureBox();
Panel panel1 = new Panel();
Color color = new Color();
Pen pen = new Pen(Color.Black, 1);
Bitmap flag = new Bitmap(40, 30);
ContextMenu cm = new ContextMenu();
public int x;
public int y;
public _createpicture () {
pictureBox2.Size = new Size(40, 30);
pictureBox2.MouseClick += new MouseEventHandler(pic_mouseclick);
pictureBox2.MouseMove += new MouseEventHandler(pic_mouseMouve);
MenuItem item_1 = cm.MenuItems.Add("Définir");
MenuItem item_2 = cm.MenuItems.Add("Supprimer");
item_1.Click += new EventHandler(item_1_Click);
item_2.Click += new EventHandler(item_2_Click);
}
private void item_1_Click(object sender, EventArgs e)
{
var myForm = new Form2();
myForm.Show();
}
private void item_2_Click(object sender, EventArgs e)
{
pictureBox2.Dispose();
}
public void _create_picture(PictureBox pictureBox2, int p, int p_2, Color color)
{
}
public void _add(Panel panel1, int p, int p_2, Color color)
{
panel1.Controls.Add(pictureBox2);
pictureBox2.BackColor = color;
Graphics flagGraphics = Graphics.FromImage(flag);
flagGraphics.DrawRectangle(pen, p, p_2, 20, 10);
flagGraphics.FillRectangle(Brushes.Red, p, p_2, 40, 30);
pictureBox2.Image = flag;
panel1.Controls.Add(pictureBox2);
}
public void pic_mouseclick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
pictureBox2.ContextMenu = cm;
}
if (e.Button == MouseButtons.Left)
{
x = e.X;
y = e.Y;
}
}
public void pic_mouseMouve(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
pictureBox2.Left += (e.X - x);
pictureBox2.Top += (e.Y - y);
}
}}
公共部分类 Form1 : Form { _createpicture _createpicture10 = new _createpicture(); . . . .
if (radioButton2.Checked) {
_createpicture10._create_picture(picturebox10, e.X, e.Y, Color.Red); _createpicture10._add(this.panel1, e.X, e.Y, Color.Red);
