示例
1、Panel(基类) 的示例
Controls/LayoutControl/PanelDemo.xaml
<Page x:Class="Windows10.Controls.LayoutControl.PanelDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:Windows10.Controls.LayoutControl" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Grid Background="Transparent"> <StackPanel Margin="10 0 10 10"> <!-- StackPanel - 流式布局控件,继承自 Panel,下面介绍 Panel 的相关知识点 Children - 子元素集合([ContentProperty(Name = "Children")]) Background - 背景色 ChildrenTransitions - 过渡效果集合 --> <StackPanel Margin="5" Background="Orange"> <StackPanel.Children> <TextBlock Text="A Panel contains a collection of UIElement objects, which are in the Children property" Margin="5" /> <TextBlock Text="Panel elements do not receive focus by default" Margin="5" /> <TextBlock Text="To compel a panel element to receive focus, set the Focusable property to true" Margin="5" /> </StackPanel.Children> <StackPanel.ChildrenTransitions> <TransitionCollection> <EntranceThemeTransition /> </TransitionCollection> </StackPanel.ChildrenTransitions> </StackPanel> </StackPanel> </Grid> </Page>
Controls/LayoutControl/PanelDemo.xaml.cs
/* * Panel(基类) - 面板控件基类(继承自 FrameworkElement, 请参见 /Controls/BaseControl/FrameworkElementDemo.xaml) */ using Windows.UI.Xaml.Controls; namespace Windows10.Controls.LayoutControl { public sealed partial class PanelDemo : Page { public PanelDemo() { this.InitializeComponent(); } } }
2、Canvas 的示例

Controls/LayoutControl/GridDemo.xaml.cs
/* * Grid - 网格布局控件(继承自 Panel, 请参见 /Controls/LayoutControl/PanelDemo.xaml) */ using Windows.UI.Xaml.Controls; namespace Windows10.Controls.LayoutControl { public sealed partial class GridDemo : Page { public GridDemo() { this.InitializeComponent(); } } }
