WPF自定義漂亮的按鈕樣式

首先打開 Microsoft Visual Studio 2008 ，新建一個WPF項目，在上面隨便放幾個按鈕：

然后給各個按鈕設置不同的背景顏色：

設置好之后就是這樣啦：

然后我們就開始在 App.xaml 文件中定義按鈕樣式了：

定義的樣式代碼如下：

以下為引用的內容： <Application x:Class="WPFButton.App"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

看了先不要頭大，我們先看看最終效果，然后回過頭來再解釋代碼：

這是常規樣式

這個是鼠標移到上面時的樣式

 

這個是鼠標點擊時的樣式

還有就是按鈕失效時的樣式

效果還算不錯吧，下面來講解代碼嘍，頭暈的同學可以現在就收拾東西回家了哈。

我們先來看這個命名為“back”的 Border 元素，它用它的 Background 屬性充當了整個按鈕的背景色。

以下為引用的內容：

<Border.Background>                                 <LinearGradientBrush StartPoint="0,0" EndPoint="0,1.5">                                     <GradientBrush.GradientStops>                                         <GradientStopCollection>                                             <GradientStop Color="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(Button.Background).(SolidColorBrush.Color)}" Offset="0"/>                                             <GradientStop Color="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(Button.Background).(SolidColorBrush.Color)}" Offset="0.4"/>                                             <GradientStop Color="#FFF" Offset="1"/>                                         </GradientStopCollection>                                     </GradientBrush.GradientStops>                                 </LinearGradientBrush>                             </Border.Background>

 

其背景所用的是一個漸變筆刷，起始值和中間值都是引用的按鈕本身的背景色，就是我們之前設置過的顏色啦，終止值是白色，這樣通過位置調整，我們可以在按鈕最下部產生一些向白色的過度色彩效果。

以下為引用的內容： <Border.BitmapEffect>                                 <OuterGlowBitmapEffect Opacity="0.7" GlowSize="0" GlowColor="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=(Button.Background).(SolidColorBrush.Color)}" />                             </Border.BitmapEffect>

 

它的 BitmapEffect 屬性我們設置了一個大小為 0 的外發光效果，平常是看不見這效果的，在這里預先設置好，是為了在鼠標移入、按下時實現動畫使用。

再來看看這個命名為“fore”的 Border 元素，它實現的是按鈕的邊框和高亮反光效果，我為它設置了一個半透明的黑色1像素邊框，使得這個邊框的色彩可以和背景色混合起來。

以下為引用的內容：  <Border.Background>                                     <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">                                         <GradientBrush.GradientStops>                                             <GradientStopCollection>                                                 <GradientStop Color="#6FFF" Offset="0.5"/>                                                 <GradientStop Color="#1111" Offset="0.51"/>                                             </GradientStopCollection>                                         </GradientBrush.GradientStops>                                     </LinearGradientBrush>                                 </Border.Background>

 

它的背景同樣采用的漸變筆刷，起始值和終止值的位置幾乎貼在一起，從而形成比較鮮明的反光度對比。

ContentPresenter 元素用於呈現按鈕原本的內容，對於按鈕來說就是按鈕上的文字了，當然也可能會存在圖片或其它東西。

以下為引用的內容：  <ContentPresenter.BitmapEffect>                                         <DropShadowBitmapEffect Color="#000" Direction="-90" ShadowDepth="2" Softness="0.1" Opacity="0.3" />                                     </ContentPresenter.BitmapEffect>

 

我為之加了一個不太明顯的陰影濾鏡以增強顯示效果。

剩下的就是些可愛又該死的 Trigger ，我們通過這些觸發器來改變按鈕在不同狀態時的外觀。

以下為引用的內容：       <!--鼠標移入移出-->                             <Trigger Property="IsMouseOver" Value="True">                                 <Trigger.EnterActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation To="6" Duration="0:0:0.2" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <ColorAnimation To="#AFFF" BeginTime="0:0:0.2" Duration="0:0:0.2" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation To="#3FFF" BeginTime="0:0:0.2" Duration="0:0:0.2" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.EnterActions>                                 <Trigger.ExitActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation Duration="0:0:0.2" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <ColorAnimation Duration="0:0:0.2" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation Duration="0:0:0.2" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.ExitActions>                             </Trigger>

 

在鼠標移入按鈕時，我依次創建了改變外發光效果大小、改變上部反光區域顏色、改變下部反光區域顏色的動畫，這里的要點就在於“Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)"”屬性設置語句，琢磨一下你就能看出這是對屬性路徑的描述，只不過它們寫起來和看起來都很讓人生氣。

以下為引用的內容：                        <!--按鈕按下彈起-->                             <Trigger Property="IsPressed" Value="True">                                 <Trigger.EnterActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation To="3" Duration="0:0:0.1" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <ColorAnimation To="#3AAA" Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation To="#2111" Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.EnterActions>                                 <Trigger.ExitActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation Duration="0:0:0.1" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.ExitActions>                             </Trigger>

 

按下和彈起按鈕時，我們做了相似的動畫改變，與前面相比只是數值略微不同。

以下為引用的內容： <!--按鈕失效-->                             <Trigger Property="IsEnabled" Value="False">                                 <Setter Property="Foreground" Value="#B444"/>                                 <Trigger.EnterActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation To="0" Duration="0:0:0.3" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <DoubleAnimation To="1" Duration="0:0:0.1" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Opacity)" />                                             <DoubleAnimation To="-135" Duration="0:0:0.1" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Direction)" />                                             <ColorAnimation To="#FFF" Duration="0:0:0.3" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Color)" />                                             <ColorAnimation To="#D555" Duration="0:0:0.3" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" />                                             <ColorAnimation To="#CEEE" Duration="0:0:0.3" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation To="#CDDD" Duration="0:0:0.3" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.EnterActions>                                 <Trigger.ExitActions>                                     <BeginStoryboard>                                         <Storyboard>                                             <DoubleAnimation Duration="0:0:0.1" Storyboard.TargetName="back" Storyboard.TargetProperty="(Border.BitmapEffect).(OuterGlowBitmapEffect.GlowSize)" />                                             <DoubleAnimation Duration="0:0:0.1" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Opacity)" />                                             <DoubleAnimation Duration="0:0:0.1" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Direction)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="content" Storyboard.TargetProperty="(ContentPresenter.BitmapEffect).(DropShadowBitmapEffect.Color)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[0].(GradientStop.Color)" />                                             <ColorAnimation Duration="0:0:0.1" Storyboard.TargetName="fore" Storyboard.TargetProperty="(Border.Background).(LinearGradientBrush.GradientStops)[1].(GradientStop.Color)" />                                         </Storyboard>                                     </BeginStoryboard>                                 </Trigger.ExitActions>                             </Trigger>

 

當按鈕失效時，我要改變很多東西，首先將文字顏色設為灰色，然后依次創建了改變外發光效果大小、改變內容陰影效果不透明度、改變內容陰影效果角度、改變內容陰影效果顏色、改變按鈕邊框顏色、改變上部反光區域顏色、改變下部反光區域顏色的動畫。

這里將先前對內容應用的陰影效果徹底改變，使之產生凹陷的效果。

好了，到這里就下課啦，文章有點冗長了，但應該對新手很有幫助，老鳥估計現在已經夢游仙境了吧。
