WPF自定义标题栏——窗口移动和按钮状态转换

其实这一部分的资料网上很多，也看了很多的例子，不过大部分都不是自己想要的结果，所以就综合网上的资料整理了一下，放在这里吧，虽然现在放弃 WPF了，不过以后还是想接着学一下，先放着吧就。

　　标题栏的移动：

　　其实这部分还是很简单的，只需加一个 (其他布局也可以)，然后响应鼠标移动事件就好了。事件响应时的代码也非常简单，判断现在鼠标是否在按下状态，如果是，调用窗口移动命令。

< Grid Name= "titleBar"  VerticalAlignment= "Top"  Height= "40"  Background= "#0F4378"  MouseMove= "TitleBar_MouseMove">
< /Grid>

　　鼠标移动时间响应：

public  void TitleBar_MouseMove( object sender, MouseEventArgs e)
{
   if(e.LeftButton == MouseButtonState.Pressed)
         this.DragMove();
}

　　窗口按钮状态转换：

　　这里指的是普通，鼠标浮上，鼠标按下三种状态在同一张图片上，通过图片的偏移来实现转换。以最小化按钮为例：

< Button Name= "minBtn"  Width= "34"  FocusVisualStyle= "{x:Null}"  Click= "MinBtn_Click">
  < Button.Style>
    < Style TargetType= "{x:Type Button}">
      < Setter Property= "Background">
        < Setter.Value>
          < DrawingBrush Stretch= "Fill"  TileMode= "Tile"  Viewport= "0,0,3,1"  Viewbox= "0,0,1,1">
            < DrawingBrush.Drawing>
              < ImageDrawing ImageSource= "res\btn_min.png"  Rect= "0,0,1,1" />
            < /DrawingBrush.Drawing>
          < /DrawingBrush>
        < /Setter.Value>
      < /Setter>
      < Setter Property= "Template">
        < Setter.Value>
          < ControlTemplate TargetType= "{x:Type Button}">
            < Grid Background= "{TemplateBinding Background}">
              < ContentPresenter VerticalAlignment= "Center"  HorizontalAlignment= "Center" />
            < /Grid>
          < /ControlTemplate>
        < /Setter.Value>
      < /Setter>
      < Style.Triggers>
        < Trigger Property= "IsMouseOver"  Value= "True">
          < Setter Property= "Background">
            < Setter.Value>
              < DrawingBrush Stretch= "Fill"  TileMode= "Tile"  Viewport= "2,0,3,1"  Viewbox= "0,0,1,1">
                < DrawingBrush.Drawing>
                  < ImageDrawing ImageSource= "res\btn_min.png"  Rect= "0,0,1,1" />
                < /DrawingBrush.Drawing>
              < /DrawingBrush>
            < /Setter.Value>
          < /Setter>
        < /Trigger>
        < Trigger Property= "IsPressed"  Value= "True">
          < Setter Property= "Background">
            < Setter.Value>
              < DrawingBrush Stretch= "Fill"  TileMode= "Tile"  Viewport= "1,0,3,1"  Viewbox= "0,0,1,1">
                < DrawingBrush.Drawing>
                  < ImageDrawing ImageSource= "res\btn_min.png"  Rect= "0,0,1,1" />
                < /DrawingBrush.Drawing>
              < /DrawingBrush>
            < /Setter.Value>
          < /Setter>
        < /Trigger>
      < /Style.Triggers>
    < /Style>
  < /Button.Style>
< /Button>

　　同样实现窗口的最小化和关闭也比较容易：

private  void MinBtn_Click( object sender, RoutedEventArgs e)
{
   this.WindowState = WindowState.Minimized;
}
private  void CloseBtn_Click( object sender, RoutedEventArgs e)
{
  mainWindow.Close();
}
