如何为自定义控件设置自定义字体？ [英] How to set custom font for custom control?

问题描述

大家好，

我通过覆盖控件创建了自定义控件。我已经实现了一些自定义来序列化和反序列化字体设置。但是，当我使用AddMemoryFont（）方法从资源设置字体时，字体不会更新为
控件。甚至我已经重写了Font属性和FontChanged事件并调用了基本函数。下面是我设置字体的代码部分，

I have created a custom control by overriding from control. I have implemented some customization to serialize and deserialize the font settings. However, when I set the font from resources by using AddMemoryFont() method, the font is not getting updated to the control. Even I have overridden the Font property and FontChanged event and called the base functions. Below are my code part to set the font,

Font font = InitializeResourceFont(Properties.Resources.Axel_Regular);

public Font InitializeResourceFont(byte[] resourceFont)
        {
            byte[] fontData = resourceFont;
            IntPtr fontPtr = Marshal.AllocCoTaskMem(fontData.Length);
            Marshal.Copy(fontData, 0, fontPtr, fontData.Length);
            uint dummy = 0;
            fonts.AddMemoryFont(fontPtr, resourceFont.Length);
            AddFontMemResourceEx(fontPtr, (uint)resourceFont.Length, IntPtr.Zero, ref dummy);
            Marshal.FreeCoTaskMem(fontPtr);

            return new Font(fonts.Families[0], 12.00F);
        }

我是否缺少更新字体来自资源？如果是，请分享任何更新字体的建议。

Is there something I'm missing to update the font from resources? If yes, share any suggestions to update the font.

嗨Arulpriya，

Hi Arulpriya,

< span class ="x_x_short_text"id ="x_x_result_box"lang ="en"style =""> 为什么不定义
字体 直接为CustomControl输入type属性
CustomFontInfo ？

Why don't you define a Font type attribute directly for CustomControl instead of CustomFontInfo?

CustomFontInfo.cs：

CustomFontInfo.cs:

    public class CustomControl : Control
    {

        public CustomControl()
        {
        }

        private CustomFontInfo _fontInfo;
        public CustomFontInfo FontInfo
        {
            get { return _fontInfo; }
            set { _fontInfo = value; }
        }

        public Font Font { get; set; }

        protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);
            //FontInfo = new CustomFontInfo(new Font("Calibri",10,FontStyle.Italic));
            //var font = InitializeResourceFont(Properties.Resources.Axel_Regular);
            //FontInfo = new CustomFontInfo(font);
            
            //e.Graphics.DrawString("Hello World", FontInfo.GdipFont, Brushes.Red, 10, 10);
            e.Graphics.DrawString("Hello World", Font, Brushes.Red, 10, 10);
        }
    }

Form1.cs：

    public partial class Form1 : Form
    {
        [DllImport("gdi32.dll")]
        private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, uint cbFont,
        IntPtr pdv, [In] ref uint pcFonts);
        private PrivateFontCollection fonts = new PrivateFontCollection();
        private Font axelFont;


        public Form1()
        {
            InitializeComponent();
            Font font = InitializeResourceFont(Properties.Resources.Axel_Regular);
            //this.customControl1.FontInfo = new CustomFontInfo(font);// new Font(font.FontFamily, 12f));
            this.customControl1.Font = font;

            this.button1.Font = font;//new Font(font.FontFamily, 12f);
        }

        public Font InitializeResourceFont(byte[] resourceFont)
        {
            byte[] fontData = resourceFont;
            IntPtr fontPtr = Marshal.AllocCoTaskMem(fontData.Length);
            Marshal.Copy(fontData, 0, fontPtr, fontData.Length);
            uint dummy = 0;
            fonts.AddMemoryFont(fontPtr, resourceFont.Length);
            AddFontMemResourceEx(fontPtr, (uint)resourceFont.Length, IntPtr.Zero, ref dummy);
            Marshal.FreeCoTaskMem(fontPtr);

            return new Font(fonts.Families[0], 12.00F);
        }
    }

问候，
