如何将绘制字符串添加到flowlayoutpanel-C#Visual Studio-WinForms [英] How to add draw string to flowlayoutpanel - c# visual studio - winforms

问题描述

嗨

我想知道如何在flowlayoutpanel中添加束带.我使用下面的代码在矩形中绘制了一个字符串.

I want to know how to add drawstring to flowlayoutpanel . I have drawn a string in a rectangle using below code.

 protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            Rectangle rect = new Rectangle(10,100,100,100);
            e.Graphics.DrawString("hello",this.Font, Brushes.Blue, rect);
        }

现在，如何将绘制的字符串添加到flowlayoutpanel?

Now, how to add this drawn string to flowlayoutpanel?

推荐答案

如果它是标准的FlowLayoutPanel，则应处理Paint事件，例如:(将FlowLayoutPanel放入Windows窗体)

if its a standard FlowLayoutPanel, hten handle the Paint event like: (put a FlowLayoutPanel to a Windows Form)

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.flowLayoutPanel1.Paint += flowLayoutPanel1_Paint;
        }

        private void flowLayoutPanel1_Paint(object sender, PaintEventArgs e)
        {
            Rectangle rect = new Rectangle(10, 100, 100, 100);
            e.Graphics.DrawString("hello", this.Font, Brushes.Blue, rect);
        }
    }

else从FlowLayoutPanel派生，并像上面一样使用OnPaint覆盖.喜欢:

else derive from FlowLayoutPanel and use the OnPaint override like you did above. Like:

    public class MyFlowPanel:FlowLayoutPanel
    {
        public MyFlowPanel()
        {
            this.BackColor = Color.Cyan;
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            Rectangle rect = new Rectangle(10, 100, 100, 100);
            e.Graphics.DrawString("hello", this.Font, Brushes.Blue, rect);
        }
    }

从设计器工具箱"的新顶部条目中构建并将其拖到表单"中.

Build and drag this to a Form from the Designer Toolbox new top entry.
