Silverlight 苹果风格按钮Mac OS Style 实现的更新版
Posted on 2011-11-03 11:35 WPF外包团队 — 长年承接WPF项目外包与WP8应用外包 阅读(1193) 评论(1) 编辑 收藏 举报在 Silverlight 2 beta 2 时,我曾经写了一篇帖子实现了苹果风格的按钮样式( Silverlight 下苹果 (Mac OS)风格按钮的实现)。
而现在 Silverlight 2 终于发布了,也给之前的代码带来了很多问题,导致无法继续使用。
经过一阵探索,我终于成功修改了这个代码,现在在正式版下也能工作正常了。其关键点如下:
1. 在 beta 2 时,需要采用 <vsm:Setter> 和 <vsm:Style> 的语法编写样式。其中 vsm 是个名称空间引用:
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
而正式版下直接用 <Style> 和 <Setter> 表签即可。
这个问题如果不修改,程序可以编译通过,但是运行时会报一个莫名其妙的 “ AG_E_PARSER_PROPERTY_NOT_FOUND ”错误。
2. ContentPresenter 和 ContentControl 控件删除了如下属性:
TextDecorations,
TextWrapping,
TextAlignment.
因此,现在必须在 template 中将 ContentPresenter 的定位改用容器 Button 的 HorizontalContentAlignment 和 VerticalContentAlignment 属性来控制。代码如下:
<ContentPresenter Margin="4,5,4,4" Content="{TemplateBinding Content}"
ContentTemplate="{TemplateBinding ContentTemplate}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
修改成功后的 Style 全部代码如下:
