WPF中的滑块开/关开关

Question

我正在寻找一个关于在iPhone上创建幻灯片ON/OFF开关的WPF教程.

以下是一个示例("发送所有流量"选项)https://secure-tunnel.com/support/software_setup/iphone/images/iphone_vpn_settings.jpg

有任何想法吗？

干杯,凯文.

Answer 1

我没有看到关于这个确切问题的教程,但我想你可以从启动Expression Blend并在其上放置CheckBox开始.然后选择CheckBox,进入主菜单 - 对象 - >编辑样式 - >编辑副本

这将使Blend生成CheckBox的默认样式,因此您可以对其进行修改.看看事情是如何运作的,你将能够取得一些成果.

基本上(除了颜色和画笔之外)你需要查看连接到IsChecked属性的触发器.例如,当IsChecked为True时,您将矩形移动到其中一个边,显示ON字并隐藏OFF字.要为此设置动画,您只需添加触发动画内外动画.

UPD:我花了10-15分钟混合制作一个"原型":

如果您有兴趣,我也建议您阅读WPF中的样式和模板.

Answer 2

我用橙色和蓝色的arconaut创建了一些基于帖子的样式.

截图:

我希望我的风格更接近iOS设备的On/Off Switch风格.这种风格的一个区别是,滑动动画只会滑动开关而不是下面的指示器.也许如果我能找到一些时间,我会以这种方式修改它.在那之前,我想分享我的结果.它并不完美,但这是代码.

一些开源的ToggleSwitches:

• ToggleSwitch看起来不错,也是由NuGet提供的.
• MahApps ToggleSwitch是大型MahApps Metro控件库的一部分.
