在WPF中，經常需要對視窗進行設定，下面講講常用的幾個設定。
視窗樣式
1、無邊框視窗
無邊框透明窗體 設定
WindowStyle="None"--無邊框，如果需要其它按鈕，如縮小、放大、收縮、關閉按鈕，可以自定義
AllowsTransparency="True"--隻有設定了AllowsTransparency，才有1、窗體真正的隐藏邊框2、背景透明有效
Background="Transparent"
視窗陰影設定
可以用Border的CornerRadius設定視窗四周圓角
設定視窗陰影--值得一提的是，如果直接用Window.Effect,效果會影響CornerRadius設定的圓角效果。
<Window.Effect>
<DropShadowEffect BlurRadius="30" Color="Gray" ShadowDepth="0" RenderingBias="Quality" ></DropShadowEffect>
</Window.Effect>
舉例：
<Window x:Class="WpfApplication4.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525" WindowStartupLocation="CenterScreen"
AllowsTransparency="True" WindowStyle="None" Background="Transparent">
<Grid>
<Border CornerRadius="5" Background="Red"></Border>
</Grid>
</Window> View Code
2、視窗按鈕
當我們設定無邊視窗時，也即是需要重新設定一套視窗的操作按鈕。
按鈕，可以用修改Button的Background或者修改Template,往其中設定圖示或者直接用Path、Border、Rectangle等基礎元素繪制。
然後添加簡單的動畫Animation
1) 方法1.下面是自定義的按鈕Style，往其中傳入圖示路徑即可
<Style TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<Rectangle x:Name="T_Rectangle" Height="15" Width="15">
<Rectangle.Fill>
<ImageBrush ImageSource="{Binding ImagesSource}"></ImageBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalAlignment}"></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="T_Rectangle" Property="Height" Value="18"></Setter>
<Setter TargetName="T_Rectangle" Property="Width" Value="18"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Rectangle" Property="Height" Value="20"></Setter>
<Setter TargetName="T_Rectangle" Property="Width" Value="20"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style> 2）方法2.直接用基礎元素繪制
Path，通過Path來畫線。當然一般水準、豎直也是可以用Rectangle/Border之類的替代
一些簡單的線條圖示用Path來做，還是很友善的。
<StackPanel Grid.Column="1" Orientation="Horizontal">
<Button x:Name="BtnMinimize" ToolTip="Minimize" Style="{StaticResource TitleBtnStyle}">
<Button.Template>
<ControlTemplate TargetType="Button">
<Border x:Name="T_Grid" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">
<Grid VerticalAlignment="Center" HorizontalAlignment="Center">
<Path x:Name="T_Path" Data="M0,0 L8,0" Stroke="Black" StrokeThickness="1"></Path>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger SourceName="T_Grid" Property="IsMouseOver" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="LightGray"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="#FFC1C1C1"></Setter>
<Setter TargetName="T_Path" Property="Margin" Value="0,4,0,0"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
<Button x:Name="BtnMaximize" ToolTip="Maximize" Style="{StaticResource TitleBtnStyle}">
<Button.Template>
<ControlTemplate TargetType="Button">
<Border x:Name="T_Grid" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">
<Rectangle x:Name="T_Rect" Stroke="Black" StrokeThickness="0.5" Height="8" Margin="5,0" Width="8"></Rectangle>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="LightGray"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="#FFC1C1C1"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
<Button x:Name="BtnRestore" ToolTip="Restore" Style="{StaticResource TitleBtnStyle}">
<Button.Template>
<ControlTemplate TargetType="Button">
<Border x:Name="T_Grid" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">
<Grid >
<Rectangle Stroke="Black" StrokeThickness="0.5" Height="7" Width="7" Margin="2,0,0,2"></Rectangle>
<Rectangle Stroke="Black" StrokeThickness="0.5" Height="7" Width="7" Fill="White" Margin="0,2,2,0"></Rectangle>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="LightGray"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="#FFC1C1C1"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
<Button x:Name="BtnClose" ToolTip="Close" Style="{StaticResource TitleBtnStyle}" Click="BtnClose_OnClick">
<Button.Template>
<ControlTemplate TargetType="Button">
<Border x:Name="T_Grid" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}">
<Grid VerticalAlignment="Center" HorizontalAlignment="Center">
<Path Data="M0,0 L8,8" Stroke="Black" StrokeThickness="1"></Path>
<Path Data="M8,0 L0,8" Stroke="Black" StrokeThickness="1"></Path>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="LightGray"></Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="T_Grid" Property="Background" Value="#FFC1C1C1"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Button.Template>
</Button>
</StackPanel> 3、視窗 resize 滑鼠自由改變視窗大小 （轉）
覆寫一個OnSourceInitialized方法，在其中添加一個委托
//重寫
protected override void OnSourceInitialized(EventArgs e)
{
base.OnSourceInitialized(e);
HwndSource hwndSource = PresentationSource.FromVisual(this) as HwndSource;
if (hwndSource != null)
{
hwndSource.AddHook(new HwndSourceHook(WndProc));
}
}
private const int WM_NCHITTEST = 0x0084;
private Point mousePoint = new Point(); //滑鼠坐标
private const int ResizeBorderAGWidth = 12;//轉角寬度
private const int ResizeBorderThickness = 4;//邊框寬度
/// <summary>
/// 委托方法
/// </summary>
/// <param name="hwnd"></param>
/// <param name="msg"></param>
/// <param name="wParam"></param>
/// <param name="lParam"></param>
/// <param name="handled"></param>
/// <returns></returns>
protected virtual IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
switch (msg)
{
case WM_NCHITTEST:
mousePoint.X = (lParam.ToInt32() & 0xFFFF);
mousePoint.Y = (lParam.ToInt32() >> 16);
// 視窗左上角
if (mousePoint.Y - Top <= ResizeBorderAGWidth && mousePoint.X - Left <= ResizeBorderAGWidth)
{
handled = true;
return new IntPtr((int)HitTest.HTTOPLEFT);
}
// 視窗左下角
else if (ActualHeight + Top - mousePoint.Y <= ResizeBorderAGWidth && mousePoint.X - Left <= ResizeBorderAGWidth)
{
handled = true;
return new IntPtr((int)HitTest.HTBOTTOMLEFT);
}
// 視窗右上角
else if (mousePoint.Y - Top <= ResizeBorderAGWidth && ActualWidth + Left - mousePoint.X <= ResizeBorderAGWidth)
{
handled = true;
return new IntPtr((int)HitTest.HTTOPRIGHT);
}
// 視窗右下角
else if (ActualWidth + Left - mousePoint.X <= ResizeBorderAGWidth && ActualHeight + Top - mousePoint.Y <= ResizeBorderAGWidth)
{
handled = true;
return new IntPtr((int)HitTest.HTBOTTOMRIGHT);
}
// 視窗左側
else if (mousePoint.X - Left <= ResizeBorderThickness)
{
handled = true;
return new IntPtr((int)HitTest.HTLEFT);
}
// 視窗右側
else if (ActualWidth + Left - mousePoint.X <= ResizeBorderThickness)
{
handled = true;
return new IntPtr((int)HitTest.HTRIGHT);
}
// 視窗上方
else if (mousePoint.Y - Top <= ResizeBorderThickness)
{
handled = true;
return new IntPtr((int)HitTest.HTTOP);
}
// 視窗下方
else if (ActualHeight + Top - mousePoint.Y <= ResizeBorderThickness)
{
handled = true;
return new IntPtr((int)HitTest.HTBOTTOM);
}
else // 視窗移動
{
//handled = true;
//return new IntPtr((int)HitTest.HTCAPTION);
return IntPtr.Zero;
}
}
return IntPtr.Zero;
} 用到的枚舉清單類：
public enum HitTest : int
{
HTERROR = -2,
HTTRANSPARENT = -1,
HTNOWHERE = 0,
HTCLIENT = 1,
HTCAPTION = 2,
HTSYSMENU = 3,
HTGROWBOX = 4,
HTSIZE = HTGROWBOX,
HTMENU = 5,
HTHSCROLL = 6,
HTVSCROLL = 7,
HTMINBUTTON = 8,
HTMAXBUTTON = 9,
HTLEFT = 10,
HTRIGHT = 11,
HTTOP = 12,
HTTOPLEFT = 13,
HTTOPRIGHT = 14,
HTBOTTOM = 15,
HTBOTTOMLEFT = 16,
HTBOTTOMRIGHT = 17,
HTBORDER = 18,
HTREDUCE = HTMINBUTTON,
HTZOOM = HTMAXBUTTON,
HTSIZEFIRST = HTLEFT,
HTSIZELAST = HTBOTTOMRIGHT,
HTOBJECT = 19,
HTCLOSE = 20,
HTHELP = 21,
} 視窗拖動
1、在界面上對布局元素如Grid,添加委托事件： MouseLeftButtonDown="UIElement_OnMouseLeftButtonDown"
2、委托方法中處理一下就行了：
private void UIElement_OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (e.ButtonState==MouseButtonState.Pressed)
{
this.DragMove();
}
