C# GDI绘制的小熊进度条

C# GDI小熊进度条

在这里插入图片描述
1、添加自定义控件winform

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace xiaoxiong
{
    public partial class CustomControl1 : Control
    {
        private int progress;
        private const int BearWidth = 50;
        private const int BearHeight = 50;
        public int Progress
        {
            get { return progress; }
            set
            {
                if (value < 0) value = 0;
                if (value > 100) value = 100;

                progress = value;
                this.Invalidate(); // Force a repaint
            }
        }
        public CustomControl1()
        {
            InitializeComponent();
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);

            Graphics g = e.Graphics;
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

            // Draw the progress bar background
            Rectangle progressBarRect = new Rectangle(0, 0, this.Width, this.Height);
            g.FillRectangle(Brushes.LightGray, progressBarRect);

            // Calculate the width of the filled part of the progress bar
            int filledWidth = (int)((double)this.Width * progress / 100);

            // Draw the filled part of the progress bar
            g.FillRectangle(Brushes.CornflowerBlue, new Rectangle(0, 0, filledWidth, this.Height));

            // Draw the bear (simplified representation)
            int bearX = this.Width - BearWidth - 10; // Position the bear to the right of the progress bar
            int bearY = (this.Height - BearHeight) / 2;

            g.FillEllipse(Brushes.Brown, bearX, bearY, BearWidth, BearHeight); // Bear's head
            g.FillEllipse(Brushes.Black, bearX + BearWidth / 4, bearY + BearHeight / 4, BearWidth / 2, BearHeight / 2); // Bear's left eye
            g.FillEllipse(Brushes.Black, bearX + BearWidth * 3 / 4, bearY + BearHeight / 4, BearWidth / 2, BearHeight / 2); // Bear's right eye
            g.DrawArc(Pens.Black, bearX + BearWidth / 4, bearY + BearHeight / 2, BearWidth / 2, BearHeight / 2, 0, 180); // Bear's left ear
            g.DrawArc(Pens.Black, bearX + BearWidth * 3 / 4, bearY + BearHeight / 2, BearWidth / 2, BearHeight / 2, 0, -180); // Bear's right ear


        }
    }
}

2、编译后添加winform窗口并找到上面的CustomControl1 控件，根据定时器即可使用该控件

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace xiaoxiong
{
    public partial class Form1 : Form
    {
       private CustomControl1 bearProgressBar;
        public Form1()
        {
            InitializeComponent();
            bearProgressBar = new CustomControl1
            {
                Location = new Point(10, 10),
                Size = new Size(300, 50),
                Progress = 10 // Set initial progress
            };

            this.Controls.Add(bearProgressBar);
        }
        public int i = 0;
        private void timer1_Tick(object sender, EventArgs e)
        {
            i=i+1;
            bearProgressBar.Progress = i;
        }
    }
}
