我的文章一定要对读者负责-否则不是好文章  ----       www.ayjs.net  aaronyang技术分享

文章导航:

  1. 介绍vs2013 WPF开发,属性代码相关技巧

  2. 实战AyImageButton 1.0细用慢讲,学会用户控件,依赖属性,属性回调事件

  3. 诞生AyImageButton 1.1 支持 控件简单写法,支持自定义AyImageButton写法,提供详细的API

  4. 效果图:

  5. AyImageButton记录

  6. 源码下载:http://pan.baidu.com/s/1eQlHly6

 


 

1. 元素基类:FrameworkElement,Control,ContentControl,UserControl,ItemsControl或者Selector,Panel, Decorator,特殊控件

2. 基本手段:

    依赖属性

   

   附加属性

    

    完整属性,简写属性,私有设置属性

    

    路由事件

   这是个验证值变化后的措施

private static readonly RoutedEvent XXChangedEvent =
              EventManager.RegisterRoutedEvent("XXChanged", RoutingStrategy.Bubble, typeof(RoutedPropertyChangedEventHandler<string>), typeof(UIElement));


          public event RoutedPropertyChangedEventHandler<string> XXChanged
          {
              add { AddHandler(XXChangedEvent, value); }
              remove { RemoveHandler(XXChangedEvent, value); }
          }

这里使用RoutedPropertyChangedEventHandler<变化的值类型T>和RoutedPropertyChangedEventArgs<变化的值类型T>  参照这样的规律RoutedPropertyChangedEvent*<变化的值类型T>


 

今天公司又停电了,坑爹的博客园的自动保存..老是保存不住。又不早了,大致讲解下,如果有不懂的地方,请评论告诉ay


 

DEMO AyImageButton V1.0 实现 图标的上下左右排版,并能够居中,为列表的ImageButton做准备

1. 新建一个UserControl,排版基本静态图。

2. 猜测可能需要用户去设置的属性在后台定义依赖属性

    

按照上面的要求列好依赖属性

接着,主要是IconDockPlacement依赖属性,我们需要增加属性改变时候回调函数

public Dock IconDockPlacement
        {
            get { return (Dock)GetValue(IconDockPlacementProperty); }
            set { SetValue(IconDockPlacementProperty, value); }
        }

        // Using a DependencyProperty as the backing store for IconDockPlacement.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty IconDockPlacementProperty =
            DependencyProperty.Register("IconDockPlacement", typeof(Dock), typeof(AyImageButton), new PropertyMetadata(Dock.Left, IconDockPlacementChanged));
private static void IconDockPlacementChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            AyImageButton aybtn = (AyImageButton)d;
            if (!aybtn.IsFixed)
            {
                Dock newDock = (Dock)e.NewValue;
                //e.Property 是被修改的属性,这里就是IconDockPlacement
                //调整文字摆放方式
                IconDockChanged(aybtn, newDock);
            }
        }

        private static void IconDockChanged(AyImageButton aybtn, Dock newDock)
        {
            if (!aybtn.IsFixed)
            {
                if (newDock == Dock.Bottom)
                {
                    aybtn.TextHorizontalAlignment = HorizontalAlignment.Center;
                    aybtn.Width = aybtn.ButtonWidthVerticalAlignment;
                    aybtn.Height = aybtn.ButtonHeightVerticalAlignment;
                    aybtn.TextFontSize = aybtn.TextFontSizeVerticalAlignment;
                    aybtn.IconHeight = aybtn.IconWidth = 32;
                    aybtn.HorizontalContentAlignment = HorizontalAlignment.Center;
                    aybtn.Padding = aybtn.PaddingVerticalAlignment;
                    aybtn.TextMargin = new Thickness(0, 0, 0, 5);
                }
                else if (newDock == Dock.Top)
                {
                    aybtn.TextHorizontalAlignment = HorizontalAlignment.Center;
                    aybtn.Width = aybtn.ButtonWidthVerticalAlignment;
                    aybtn.Height = aybtn.ButtonHeightVerticalAlignment;
                    aybtn.TextFontSize = aybtn.TextFontSizeVerticalAlignment;
                    aybtn.IconHeight = aybtn.IconWidth = 32;
                    aybtn.HorizontalContentAlignment = HorizontalAlignment.Center;
                    aybtn.Padding = aybtn.PaddingVerticalAlignment;
                    aybtn.TextMargin = new Thickness(0, 5, 0, 0);
                }
                else if (newDock == Dock.Left)
                {
                    aybtn.TextVerticalAlignment = VerticalAlignment.Center;
                    aybtn.TextHorizontalAlignment = HorizontalAlignment.Left;
                    aybtn.Width = 120;
                    aybtn.Height = 40;
                    if (aybtn.TextFontSize != 14) { 
                    
                    }
                    aybtn.TextFontSize = 14;

                    aybtn.IconHeight = aybtn.IconWidth = 16;
                    aybtn.HorizontalContentAlignment = HorizontalAlignment.Left;
                    //猜测右侧,说明右侧值不一样 例如 5,5,5,10 要变成 10,5,5,5
                    if (aybtn.PaddingHorizontalAlignment.Left != aybtn.PaddingHorizontalAlignment.Right &&
                        aybtn.PaddingHorizontalAlignment.Left == aybtn.PaddingHorizontalAlignment.Top
                        )
                    {
                        aybtn.Padding = new Thickness(aybtn.PaddingHorizontalAlignment.Right, aybtn.PaddingHorizontalAlignment.Top, aybtn.PaddingHorizontalAlignment.Left, aybtn.PaddingHorizontalAlignment.Bottom);
                    }
                    else
                    {
                        aybtn.Padding = aybtn.PaddingHorizontalAlignment;
                    }

                    aybtn.TextMargin = new Thickness(5, 0, 0, 0);
                }
                else if (newDock == Dock.Right)
                {
                    aybtn.TextHorizontalAlignment = HorizontalAlignment.Right;
                    aybtn.TextVerticalAlignment = VerticalAlignment.Center;
                    aybtn.Width = 120;
                    aybtn.Height = 40;
                    aybtn.TextFontSize = 14;
                    aybtn.IconHeight = aybtn.IconWidth = 16;
                    aybtn.HorizontalContentAlignment = HorizontalAlignment.Right;
                    //猜测左侧,说明右侧值不一样 例如 10,5,5,5要变成5,5,5,10
                    if (aybtn.PaddingHorizontalAlignment.Left != aybtn.PaddingHorizontalAlignment.Right &&
                        aybtn.PaddingHorizontalAlignment.Right == aybtn.PaddingHorizontalAlignment.Top
                        )
                    {
                        aybtn.Padding = new Thickness(aybtn.PaddingHorizontalAlignment.Right, aybtn.PaddingHorizontalAlignment.Top, aybtn.PaddingHorizontalAlignment.Left, aybtn.PaddingHorizontalAlignment.Bottom);
                    }
                    else
                    {
                        aybtn.Padding = aybtn.PaddingHorizontalAlignment;
                    }
                    aybtn.TextMargin = new Thickness(0, 0, 5, 0);
                }
            }
        }

由于默认的IconDockPlacement属性如果和使用者提供的值一致的话,就不会触发IconDockPlacementChanged事件,也就不会调整按钮的样子。所以我把其中的一部分代码封装一点方法,然后在OnRender的时候,调用一下排版方法

  protected override void OnRender(DrawingContext drawingContext)
        {
            IconDockChanged(this, this.IconDockPlacement);            base.OnRender(drawingContext);
        }

这里我定义了IsFixed表示是否修复控件的默认行为,加在了IconDockPlacementChanged的排版代码里面,是为了让用户可以更diy自己的ImageButton,不受默认样式限制。默认等于false,表示默认行为,等于true时候,表示解除控件默认排版

完整代码:所以没什么难度了,就是依赖属性和一个依赖属性的属性验证。

控件的布局,我们将静态的布局画好后,一一替换成动态的即可,代码有些啰嗦,原理很简单,找到根元素UserControl,然后绑定它的属性值

<UserControl

使用方式:

    <Canvas>
        <StackPanel Background="Yellow">
            <local:AyImageButton x:Name="btnTop" IconSource="icons/set_64.png" Background="AliceBlue" TextContent="全部软件" IconDockPlacement="Left" 
                             Canvas.Left="272" Canvas.Top="24" PaddingHorizontalAlignment="10,5,5,5"  HorizontalContentAlignment="Left"

        </StackPanel>


        <local:AyImageButton x:Name="btnTopBottom" MouseDown="btnTopBottom_MouseDown" IsFixed="true" IconSource="icons/set_64.png" ButtonBackground="#F1F1F1" IconWidth="16" IconHeight="16"
                             TextContent="左键Top,右击Bottom" TextColor="#808080"   Width="230" Height="40" IconMargin="20,0,0,0"  TextMargin="5,0,20,0" IconDockPlacement="Left"  Canvas.Left="236" Canvas.Top="250"/>

                             TextContent="左键Left,右击Right" TextColor="#808080"   Width="230" Height="40" IconMargin="20,0,0,0"  TextMargin="5,0,20,0" IconDockPlacement="Left"  Canvas.Left="226" Canvas.Top="205"/>
    </Canvas>
</Window>

单击按钮,只是修改控件的IconDockPlacement值

private void btnTopBottom_MouseDown(object sender, MouseButtonEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                btnTop.IconDockPlacement = Dock.Top;
                btnTop2.IconDockPlacement = Dock.Top;
            }
            else   //快捷菜单键
            {
                btnTop.IconDockPlacement = Dock.Bottom;
                btnTop2.IconDockPlacement = Dock.Bottom;
            }
        }

        private void btnLeftRight_MouseDown(object sender, MouseButtonEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                btnTop.IconDockPlacement = Dock.Left;
                btnTop2.IconDockPlacement = Dock.Left;
            }
            else   //快捷菜单键
            {
                btnTop.IconDockPlacement = Dock.Right;
                btnTop2.IconDockPlacement = Dock.Right;
            }
        }

如果IsFixed等于false,则默认的很多特性都无法使用,根据事件中得到的。

 

 OK,现在我们把IsFixed="True" ,做一个超大的按钮,然后设置这些被禁用的属性

<local:AyImageButton x:Name="btnTest1" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Left" 
                             Canvas.Left="216" Canvas.Top="90"  HorizontalContentAlignment="Center"
                             ButtonWidthVerticalAlignment="88" 
                             TextFontSize="32" Width="280" Height="80" IsFixed="True"  IconWidth="64" IconHeight="64" TextColor="#fff" PaddingHorizontalAlignment="15,0,0,15"
                             />

效果图:

  <local:AyImageButton x:Name="btnTest1" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Left" 
                             Canvas.Left="216" Canvas.Top="90"  HorizontalContentAlignment="Center"
                             ButtonWidthVerticalAlignment="88" 
                             TextFontSize="32" Width="280" Height="80" IsFixed="True"  IconWidth="64" IconHeight="64" TextColor="#fff" PaddingHorizontalAlignment="15,0,0,15"
                             />

垂直排版

<local:AyImageButton x:Name="btnTest1" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Top" 
                             Canvas.Left="209" Canvas.Top="27"  HorizontalContentAlignment="Center"
                             TextFontSize="32" Width="280" Height="160" IsFixed="True"  IconWidth="64" IconHeight="64" TextColor="#fff" PaddingHorizontalAlignment="15,0,0,15"
                             ButtonHeightVerticalAlignment="150"
                             ButtonWidthVerticalAlignment="68"
                             IconMargin="0,15,0,0"
                             />

好吧,我来修复这个问题

DEMO AyImageButton V1.1

真的不能怕麻烦,于是,我增加了IconWidthHorizontal,IconHeightHorizontal,IconHeightVertical,IconWidthVertical并且修改了垂直布局时候按钮宽度的属性名和高度的属性名为HeightVerticalAlignment,WidthVerticalAlignment。去掉了Button的前缀还有一些属性不是Alignment类型的去掉了Alignment后缀,修改了部分属性,例如IsFixed改名为 IsCustomed 表示是否自定义排版,默认false,表示采用系统的。移动了OnRender的代码到EndInit()中去了

修改后的前台不变,AyImageButton的后台代码为:

AyImageButton V1.1

使用方法,这也是IsCustomed=true时候最详细的写法:

引入空间:

xmlns:local="clr-namespace:WpfApplication4"
<local:AyImageButton x:Name="btnTest2" IconSource="icons/set_64.png" Background="#55B472" TextContent="AY超大按钮" IconDockPlacement="Top" 
                             Canvas.Left="212" Canvas.Top="50"  HorizontalContentAlignment="Center" TextColor="#fff"
                             IsCustomed="True"  
                             IconWidthHorizontal="32" IconHeightHorizontal="32"
                             IconWidthVertical="64" IconHeightVertical="64"
                             PaddingHorizontal="18,0,0,0" PaddingVertical="0"
                             WidthHorizontal="280" HeightHorizontal="80"
                             WidthVertical="280" HeightVertical="160"
                             TextFontSizeHorizontal="32" TextFontSizeVertical="48"
                             />

接着给超大按钮增加鼠标按下事件MouseDown="btnTest2_MouseDown"

int index2 = 1;
        private void btnTest2_MouseDown(object sender, MouseButtonEventArgs e)
        {
            index2++;
            if (index2 == 1)
            {
                btnTop.IconDockPlacement = Dock.Left;
                btnTop2.IconDockPlacement = Dock.Left;
            }
            else if (index2 == 2)
            {
                btnTop.IconDockPlacement = Dock.Right;
                btnTop2.IconDockPlacement = Dock.Right;
            }
            else if (index2 == 3)
            {
                btnTop.IconDockPlacement = Dock.Top;
                btnTop2.IconDockPlacement = Dock.Top;
            }
            else if (index2 == 4)
            {
                btnTop.IconDockPlacement = Dock.Bottom;
                btnTop2.IconDockPlacement = Dock.Bottom;
                index2 = 0;
            }
        }

效果演示:

 OK到目前为止我们的AyImageButton 1.1完成了。

 

AyButton暂时思路,需要增加的功能:

     v1.3 支持纯图片显示或者纯文字,支持命令,支持鼠标移入移出按下动画效果,禁用的效果,支持字体Icon

     v1.4 支持radio效果,按钮组,只选中一个,新控件AyImageMenuButton

     v1.5 新控件AyImageSplitButton
