[Winodows Phone 7控件详解]容器控件
在Windows Phone7中存在着多个容器控件,这些控件主要是用来界面的布局设置,以及包容多个控件时的布局设置。
一.Grid控件:主要用于界面的布局,这个和web page里的很相似,可以通过网格布置规划界面,也可以嵌套使用。
<Grid x:Name="LayoutRoot" Background="#DCDCDC" Width="400" Height="300" ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="250" />
<ColumnDefinition Width="150" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="2*" />
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" FontWeight="Bold" Text="Contoso Corporation" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Grid x:Name="FormLayoutGrid" Grid.Row="1" Grid.Column="0" ShowGridLines="True">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="First Name" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
<TextBox Grid.Row="0" Grid.Column="1" Margin="10" />
<TextBlock Grid.Row="1" Grid.Column="0" Text="Last Name" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
<TextBox Grid.Row="1" Grid.Column="1" Margin="10" />
<TextBlock Grid.Row="2" Grid.Column="0" Text="Address" Margin="10" HorizontalAlignment="Left" VerticalAlignment="Center" />
<TextBox Grid.Row="2" Grid.Column="1" Margin="10" />
</Grid>
</Grid>
二.Canvas控件: 容器、布局控件,主要是用绝对坐标来定位子控件。对于游戏开发来说用处很大。
<Canvas x:Name="C1" Grid.Row="2">
<CheckBox x:Name="CheckBox3" Content="CheckBox3" Canvas.Top="50" Canvas.Left="100" Canvas.ZIndex="1" />
</Canvas>
也可以使用代码来控制
Canvas.SetLeft();
Canvas.SetTop();
Canvas.SetZIndex();//控制子控件在Z轴上的顺序。
三.StackPanel控件:容器、布局控件,主要用来多个子控件的纵向、横向的布局控制。
<StackPanel x:Name="stackPanel1" Margin="20" Orientation="Vertical" >
<Rectangle Fill="Red" Width="50" Height="50" Margin="5" />
<Rectangle Fill="Blue" Width="50" Height="50" Margin="5" />
<Rectangle Fill="Green" Width="50" Height="50" Margin="5" />
<Rectangle Fill="Purple" Width="50" Height="50" Margin="5" />
</StackPanel>
可以使用下面的方法向上面的StackPanel中动态插入一个Rectangle
private void button1_Click(object sender, RoutedEventArgs e)
{
Rectangle rect = new Rectangle() { Fill = new SolidColorBrush(Colors.Yellow),Width=50,Height=50};
stackPanel1.Children.Insert(2, rect);
}
四.Border控件: 用于包容一个控件并为其绘制边框,并且通过参数设置可以产生多种不同的边框效果。(不太应该算为容器控件,但是又觉得放在别的类里又不是很合适。Jake Lin 和李振都这么分,我采纳了这个观点)
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,12">
<Border Background="Coral" Width="300" Height="40" Padding="10" CornerRadius="20">
<TextBlock FontSize="16">Text Surrounded by a Border</TextBlock>
</Border>
<Border x:Name="b1" Width="200" Height="200" Background="Gold" BorderBrush="Aquamarine" BorderThickness="10, 5, 20, 40" Margin="119,346,137,49" CornerRadius="25, 200, 10, 15" >
<TextBox Height="67" Name="textBox1" Text="Test Border" Background="Gold" Foreground="White" BorderBrush="Gold" Width="170" VerticalAlignment="Bottom"/>
</Border>
</Grid>
BorderThickness:边框宽度,设置不同的值使四个边产生不同的宽度。
CornerRadius:边角半径,设置不同的值四个边角产生不同的弧度。
五.PopUp控件:严格来讲这个不应该算作容器控件,但是它可以把包含在其中的控件显示在当前页的最前面,可以被打开和关闭。可以用来制作自定义的MessageBox、WaitingBox等。
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,36,132">
<Image Source="Images/1.jpg" Height="426" HorizontalAlignment="Left" Margin="25,25,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="386" />
<!-- 这个容器可以被打开和关闭 -->
<Popup IsOpen="True" HorizontalAlignment="Left" Margin="92,106,0,0" Name="popup1" VerticalAlignment="Top" Height="250" Width="250" >
<Canvas Width="250" Height="250" Background="Red" VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBlock Margin="30,120,0,0" Text="我在当前页面的上层"/>
</Canvas>
</Popup>
</Grid>
<Button Content="打开" Grid.Row="1" Height="72" HorizontalAlignment="Left" Margin="64,523,0,0" Name="btnOpen" VerticalAlignment="Top" Width="160" Click="btnOpen_Click" />
<Button Content="关闭" Height="72" HorizontalAlignment="Left" Margin="230,523,0,0" Name="btnClose" VerticalAlignment="Top" Width="160" Grid.Row="1" Click="btnClose_Click" />
</Grid>
六.ScrollView: 滚动查看器控件,也算是一个容器控件,它可以用来拖动显示其所包含的控件的内容。
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Canvas>
<!-- A large TextBlock. -->
<!-- A large TextBlock. -->
<TextBlock Canvas.Top="60" Canvas.Left="-50" Width="400" TextWrapping="Wrap"
Text="I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted, too, with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news, With many cheerful facts about the square of the hypotenuse." Margin="78,0,78,201" />
<!-- The same large TextBlock, wrapped in a ScrollViewer. -->
<!-- It can be scrolled in either direction, since VerticalScrollBarVisibility -->
<!-- has a default value of Visible. -->
<ScrollViewer BorderBrush="Green" BorderThickness="5" Height="200" Width="300" HorizontalScrollBarVisibility="Auto" Canvas.Top="400" Canvas.Left="80">
<TextBlock Width="300" TextWrapping="Wrap"
Text="I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted, too, with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news, With many cheerful facts about the square of the hypotenuse." />
</ScrollViewer>
</Canvas>
</Grid>
