在列表框中插入具有特定颜色的项目

Question

我正在尝试在列表框中插入项目，但我想根据整数为特定项目的文本着色。如何在列表框中插入具有特定颜色的项目？

谢谢！

Answer 1

将DrawMode设置为Listbox控件的OwnerDrawFixed。并将listBox_DrawItem事件处理程序关联到它listbox draw item

private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
    e.DrawBackground();
    Graphics yourObj = e.Graphics;

    yourObj .FillRectangle(new SolidBrush(Color.Red), e.Bounds);

    e.DrawFocusRectangle();
}

描述

ListBox项可以是任何类型的对象。这意味着您无法在添加ListBox项时为其设置颜色。

您需要DrawItem事件。

  

ListBox.DrawItem事件在所有者绘制的ListBox的可视方面发生更改时发生。

示例

private void lstBox_DrawItem(object sender, _
      System.Windows.Forms.DrawItemEventArgs e)
{
//
// Draw the background of the ListBox control for each item.
// Create a new Brush and initialize to a Black colored brush
// by default.
//
e.DrawBackground();
Brush myBrush = Brushes.Black;
//
// Determine the color of the brush to draw each item based on 
// the index of the item to draw.
//
switch (e.Index)
{
    case 0:
        myBrush = Brushes.Red;
        break;
    case 1:
        myBrush = Brushes.Orange;
        break;
    case 2:
        myBrush = Brushes.Purple;
        break;
}
//
// Draw the current item text based on the current 
// Font and the custom brush settings.
//
e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), 
    e.Font, myBrush,e.Bounds,StringFormat.GenericDefault);
//
// If the ListBox has focus, draw a focus rectangle 
// around the selected item.
//
e.DrawFocusRectangle();
}

也许这段代码会给你一些想法......

                listView1.Items.Clear();
                int k = 0;
                foreach (Player p in players)
                {
                    ListViewItem lvitem = new ListViewItem();
                    lvitem.Text = p.name;
                    lvitem.BackColor = p.color;
                    listView1.Items.Add(lvitem);

                    k++;
                }
