WPF 之 自定义窗体标题栏

　　在WPF中自定义窗体标题栏，首先需要将窗体的WindowStyle属性设置为None，隐藏掉WPF窗体的自带标题栏。然后可以在窗体内部自定义一个标题栏。

　　例如，标题栏如下:

<WrapPanel Height="30" MouseMove="TitleBar_MouseMove" MouseDown="TitleBar_MouseDown" Background="#4C9CFB" DockPanel.Dock="Top">
<TextBlock Name="txtTitle" Margin="1,0,0,0"  Padding="5,3,2,3" Text="个人信息"
HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="14" FontFamily="微软雅黑"
Foreground="White"/>
<custom:ImageButton x:Name="btn_min" Template="{StaticResource ImageButton_Template}" Margin="560,5,0,0"
Source="../res/img/btn_min1.jpg" ImgWidth="14" ImgHeight="14" Click="btn_min_Click" Grid.Column="0"/>
<custom:ImageButton x:Name="btn_max" Template="{StaticResource ImageButton_Template}" Margin="30,5,0,0"
Source="../res/img/btn_close1.jpg" ImgWidth="14" ImgHeight="14" Click="btn_close_Click">
</custom:ImageButton>
</WrapPanel>

　　在后台，为TitleBar添加了MouseMove事件，后台处理代码:

　　#region 标题栏事件

/// <summary>
/// 窗口移动事件
/// </summary>
private void TitleBar_MouseMove(object sender, MouseEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
this.DragMove();
}
}

int i = 0;
/// <summary>
/// 标题栏双击事件
/// </summary>
private void TitleBar_MouseDown(object sender, MouseButtonEventArgs e)
{
i += 1;
System.Windows.Threading.DispatcherTimer timer = new System.Windows.Threading.DispatcherTimer();
timer.Interval = new TimeSpan(0, 0, 0, 0, 300);
timer.Tick += (s, e1) => { timer.IsEnabled = false; i = 0; };
timer.IsEnabled = true;

if (i % 2 == 0)
{
timer.IsEnabled = false;
i = 0;
this.WindowState = this.WindowState == WindowState.Maximized ?
WindowState.Normal : WindowState.Maximized;
}
}

/// <summary>
/// 窗口最小化
/// </summary>
private void btn_min_Click(object sender, RoutedEventArgs e)
{
this.WindowState = WindowState.Minimized; //设置窗口最小化
}

/// <summary>
/// 窗口最大化与还原
/// </summary>
private void btn_max_Click(object sender, RoutedEventArgs e)
{
if (this.WindowState == WindowState.Maximized)
{
this.WindowState = WindowState.Normal; //设置窗口还原
}
else
{
this.WindowState = WindowState.Maximized; //设置窗口最大化
}
}

/// <summary>
/// 窗口关闭
/// </summary>
private void btn_close_Click(object sender, RoutedEventArgs e)
{
this.Close();
}

#endregion 标题栏事件
