如何在C#中制作字体组合框? [英] How to make a Font Combobox in C#?

问题描述

我想在ac#.NET 4.5 Windows窗体应用程序(请注意:不是WPF)中制作一个组合框，该组合框显示系统上所有truetype安装的字体，并且每种字体都用其表示的字体进行格式化("Times"格式与Times，"Arial"格式为arial等).

I want to make a combobox in a c# .NET 4.5 Windows Forms application (note: not WPF) that displays all the truetype installed font on the system and that every font is formatted with the font it's representing ("Times" formatted with Times, "Arial" formatted with arial and so on).

该怎么做?

推荐答案

使用ComboBox.DrawItem事件处理程序.

public YourForm()
{
    InitializeComponent();

    ComboBoxFonts.DrawItem += ComboBoxFonts_DrawItem;           
    ComboBoxFonts.DataSource = System.Drawing.FontFamily.Families.ToList();
}

private void ComboBoxFonts_DrawItem(object sender, DrawItemEventArgs e)
{
    var comboBox = (ComboBox)sender;
    var fontFamily = (FontFamily)comboBox.Items[e.Index];
    var font = new Font(fontFamily, comboBox.Font.SizeInPoints);

    e.DrawBackground();
    e.Graphics.DrawString(font.Name, font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}

要使用ComboBox.DrawItem，您需要设置ComboBox.DrawMode = DrawMode.OwnerDrawFixed
