在Windows Forms(WinForms)中,ListView控件可以通过自定义绘制来实现主题定制
listView1.OwnerDraw = true;
listView1.DrawItem += ListView1_DrawItem;
listView1.DrawSubItem += ListView1_DrawSubItem;
listView1.DrawColumnHeader += ListView1_DrawColumnHeader;
private void ListView1_DrawItem(object sender, DrawListViewItemEventArgs e)
{
// 自定义绘制列表项
e.DrawDefault = true;
}
private void ListView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
{
// 自定义绘制子项
e.DrawDefault = true;
}
private void ListView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
// 自定义绘制列标题
e.DrawDefault = true;
}
private void ListView1_DrawItem(object sender, DrawListViewItemEventArgs e)
{
if (e.Item.Selected)
{
e.Graphics.FillRectangle(Brushes.LightBlue, e.Bounds);
e.Graphics.DrawString(e.Item.Text, listView1.Font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}
else
{
e.Graphics.FillRectangle(Brushes.White, e.Bounds);
e.Graphics.DrawString(e.Item.Text, listView1.Font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}
}
private void ListView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
{
if (e.Item.Selected)
{
e.Graphics.FillRectangle(Brushes.LightBlue, e.Bounds);
e.Graphics.DrawString(e.SubItem.Text, listView1.Font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}
else
{
e.Graphics.FillRectangle(Brushes.White, e.Bounds);
e.Graphics.DrawString(e.SubItem.Text, listView1.Font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}
}
private void ListView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
e.Graphics.FillRectangle(Brushes.LightGray, e.Bounds);
e.Graphics.DrawString(e.Header.Text, listView1.Font, Brushes.Black, e.Bounds.X, e.Bounds.Y);
}
通过上述步骤,可以实现ListView控件在WinForms中的主题定制。请注意,这只是一个简单的示例,您可以根据需要进一步自定义绘制。
