C# XAML扇出按钮
WPF/XAML中是否有类似于Windows10(我想还有Windows8.1)屏幕键盘中的按钮控件?我的意思是当按下时,它们“扇出”成多个按钮,释放时可以拖动到并激活这些按钮(即使单击稍微远离按键)。若否,如何落实?C# XAML扇出按钮,c#,wpf,xaml,C#,Wpf,Xaml,WPF/XAML中是否有类似于Windows10(我想还有Windows8.1)屏幕键盘中的按钮控件?我的意思是当按下时,它们“扇出”成多个按钮,释放时可以拖动到并激活这些按钮(即使单击稍微远离按键)。若否,如何落实? 我不知道有默认控件可以执行此操作。但是,我认为您可以通过以下方式获得此功能: 1) 有一个包含主文本选择的按钮 2) 创建一个包含默认值和所有要显示的变体的按钮网格弹出窗口 3) 保持主按钮和弹出窗口中按钮的样式一致 4) 显示弹出窗口时,将其定位,使主文本按钮与弹出窗口中显示的
