WPF自定义控件与样式(2)-自定义按钮FButton
一.前言.效果图
申明:WPF自定义控件与样式是一个系列文章,前后是有些关联的,但大多是按照由简到繁的顺序逐步发布的等,若有不明白的地方可以参考本系列前面的文章,文末附有部分文章链接。
还是先看看效果图吧:
定义Button按钮名称叫FButton,主要是集成了字体图标(参考上一篇:WPF自定义控件与样式1-矢量字体图标(iconfont))。其实在WPF里,要实现本文FButton的需求,完全可以不用自定义控件,使用样式、模板就可以搞定了的。
二.按钮FButton控件定义
2.1 FButton继承自微软基础控件Button (C#代码)
FButton继承自微软基础控件Button,没有什么逻辑代码,主要扩展了几个属性:
- 控件外观控制的属性,如圆角、鼠标悬浮前景色背景色、是否开启动画(鼠标悬停时小图标转一圈,移开又转回去)、鼠标按下颜色等;
- 字体图标相关属性,如字符值、字体图标大小、字体图标间距等。
详见代码:
- /// <summary>
- /// FButton.xaml 的交互逻辑
- /// </summary>
- public partial class FButton : Button
- {
- public static readonly DependencyProperty PressedBackgroundProperty =
- DependencyProperty.Register("PressedBackground", typeof(Brush), typeof(FButton), new PropertyMetadata(Brushes.DarkBlue));
- /// <summary>
- /// 鼠标按下背景样式
- /// </summary>
- public Brush PressedBackground
- {
- get { return (Brush)GetValue(PressedBackgroundProperty); }
- set { SetValue(PressedBackgroundProperty, value); }
- }
- public static readonly DependencyProperty PressedForegroundProperty =
- DependencyProperty.Register("PressedForeground", typeof(Brush), typeof(FButton), new PropertyMetadata(Brushes.White));
- /// <summary>
- /// 鼠标按下前景样式(图标、文字)
- /// </summary>
- public Brush PressedForeground
- {
- get { return (Brush)GetValue(PressedForegroundProperty); }
- set { SetValue(PressedForegroundProperty, value); }
- }
- public static readonly DependencyProperty MouseOverBackgroundProperty =
- DependencyProperty.Register("MouseOverBackground", typeof(Brush), typeof(FButton), new PropertyMetadata(Brushes.RoyalBlue));
- /// <summary>
- /// 鼠标进入背景样式
- /// </summary>
- public Brush MouseOverBackground
- {
- get { return (Brush)GetValue(MouseOverBackgroundProperty); }
- set { SetValue(MouseOverBackgroundProperty, value); }
- }
- public static readonly DependencyProperty MouseOverForegroundProperty =
- DependencyProperty.Register("MouseOverForeground", typeof(Brush), typeof(FButton), new PropertyMetadata(Brushes.White));
- /// <summary>
- /// 鼠标进入前景样式
- /// </summary>
- public Brush MouseOverForeground
- {
- get { return (Brush)GetValue(MouseOverForegroundProperty); }
- set { SetValue(MouseOverForegroundProperty, value); }
- }
- public static readonly DependencyProperty FIconProperty =
- DependencyProperty.Register("FIcon", typeof(string), typeof(FButton), new PropertyMetadata("\ue604"));
- /// <summary>
- /// 按钮字体图标编码
- /// </summary>
- public string FIcon
- {
- get { return (string)GetValue(FIconProperty); }
- set { SetValue(FIconProperty, value); }
- }
- public static readonly DependencyProperty FIconSizeProperty =
- DependencyProperty.Register("FIconSize", typeof(int), typeof(FButton), new PropertyMetadata());
- /// <summary>
- /// 按钮字体图标大小
- /// </summary>
- public int FIconSize
- {
- get { return (int)GetValue(FIconSizeProperty); }
- set { SetValue(FIconSizeProperty, value); }
- }
- public static readonly DependencyProperty FIconMarginProperty = DependencyProperty.Register(
- "FIconMargin", typeof(Thickness), typeof(FButton), new PropertyMetadata(new Thickness(, , , )));
- /// <summary>
- /// 字体图标间距
- /// </summary>
- public Thickness FIconMargin
- {
- get { return (Thickness)GetValue(FIconMarginProperty); }
- set { SetValue(FIconMarginProperty, value); }
- }
- public static readonly DependencyProperty AllowsAnimationProperty = DependencyProperty.Register(
- "AllowsAnimation", typeof(bool), typeof(FButton), new PropertyMetadata(true));
- /// <summary>
- /// 是否启用Ficon动画
- /// </summary>
- public bool AllowsAnimation
- {
- get { return (bool)GetValue(AllowsAnimationProperty); }
- set { SetValue(AllowsAnimationProperty, value); }
- }
- public static readonly DependencyProperty CornerRadiusProperty =
- DependencyProperty.Register("CornerRadius", typeof(CornerRadius), typeof(FButton), new PropertyMetadata(new CornerRadius()));
- /// <summary>
- /// 按钮圆角大小,左上,右上,右下,左下
- /// </summary>
- public CornerRadius CornerRadius
- {
- get { return (CornerRadius)GetValue(CornerRadiusProperty); }
- set { SetValue(CornerRadiusProperty, value); }
- }
- public static readonly DependencyProperty ContentDecorationsProperty = DependencyProperty.Register(
- "ContentDecorations", typeof(TextDecorationCollection), typeof(FButton), new PropertyMetadata(null));
- public TextDecorationCollection ContentDecorations
- {
- get { return (TextDecorationCollection)GetValue(ContentDecorationsProperty); }
- set { SetValue(ContentDecorationsProperty, value); }
- }
- static FButton()
- {
- DefaultStyleKeyProperty.OverrideMetadata(typeof(FButton), new FrameworkPropertyMetadata(typeof(FButton)));
- }
- }
2.2 FButton控件模板定义
模板内容分为两部分,第一部分为为基本结构,第二部分就是触发器,用触发器实现按钮不同状态的样式控制,详见代码:
- <!--FButton模板-->
- <ControlTemplate x:Key="FButton_Template" TargetType="{x:Type local:FButton}">
- <Border x:Name="border" Background="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path= Background}"
- Height="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Height}"
- CornerRadius="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=CornerRadius}"
- Width="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Width}">
- <!--Icon/Text-->
- <StackPanel Orientation="Horizontal" VerticalAlignment="Center"
- Margin="{TemplateBinding Padding}"
- HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}">
- <TextBlock x:Name="icon" Margin="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=FIconMargin}"
- RenderTransformOrigin="0.5,0.5" Style="{StaticResource FIcon}"
- Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path= FIcon}"
- FontSize="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path= FIconSize}"
- Foreground="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path= Foreground}">
- <TextBlock.RenderTransform>
- <RotateTransform x:Name="transIcon" Angle="0"/>
- </TextBlock.RenderTransform>
- </TextBlock>
- <TextBlock VerticalAlignment="Center" x:Name="txt"
- TextDecorations="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=ContentDecorations}"
- Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Content}"
- FontSize="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=FontSize}"
- Foreground="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Foreground}"></TextBlock>
- </StackPanel>
- </Border>
- <!--触发器-->
- <ControlTemplate.Triggers>
- <!--设置鼠标进入时的背景、前景样式-->
- <Trigger Property="IsMouseOver" Value="True">
- <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=MouseOverBackground}" TargetName="border" />
- <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=MouseOverForeground}" TargetName="icon"/>
- <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=MouseOverForeground}" TargetName="txt"/>
- </Trigger>
- <!--Ficon的动画触发器-->
- <MultiTrigger>
- <MultiTrigger.Conditions>
- <Condition Property="IsMouseOver" Value="true"></Condition>
- <Condition Property="AllowsAnimation" Value="true"></Condition>
- </MultiTrigger.Conditions>
- <MultiTrigger.EnterActions>
- <BeginStoryboard>
- <Storyboard>
- <DoubleAnimation Storyboard.TargetName="transIcon" Storyboard.TargetProperty="Angle" To="180" Duration="0:0:0.2" />
- </Storyboard>
- </BeginStoryboard>
- </MultiTrigger.EnterActions>
- <MultiTrigger.ExitActions>
- <BeginStoryboard>
- <Storyboard>
- <DoubleAnimation Storyboard.TargetName="transIcon" Storyboard.TargetProperty="Angle" To="0" Duration="0:0:0.2" />
- </Storyboard>
- </BeginStoryboard>
- </MultiTrigger.ExitActions>
- </MultiTrigger>
- <!--鼠标按下时的前景、背景样式-->
- <Trigger Property="IsPressed" Value="True">
- <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=PressedBackground}" TargetName="border" />
- <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=PressedForeground}" TargetName="icon"/>
- <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
- Path=PressedForeground}" TargetName="txt"/>
- </Trigger>
- <Trigger Property="IsEnabled" Value="false">
- <Setter Property="Opacity" Value="0.5" TargetName="border"/>
- </Trigger>
- </ControlTemplate.Triggers>
- </ControlTemplate>
2.3 FButton基本样式
样式定义代码:
