WPF学习笔记（2）

1.

//启用自定义字体

此示例需将Bayern ttf字体放置于工程目录下   "./#Bayern" ，如果为已安装的字体则不需要

    <Grid>
      <Label Name="tst" FontSize="20" FontFamily="./#Bayern"
             >This is an embedded font</Label>
    </Grid>

2.

//在button里绘制多边形

 <Button Margin="10">
    <Grid>      
        <Polygon Points="100,25 125,0 200,25 125,50"
             Fill="LightSteelBlue" />
        <Polygon Points="100,25 75,0 0,25 75,50"
             Fill="White"/>      
    </Grid>
  </Button>

//把lable和textbox进行绑定

  <StackPanel Margin="5">
    <Label Target="{Binding ElementName=txtA}">Choose _A</Label>

    <Label Target="{Binding ElementName=txtB}">Choose _B</Label>
    <TextBox Name="txtB"></TextBox>

  </StackPanel>

//RadioButtonGroup  

不指定GroupName 则按父容器划分

<StackPanel>
      <GroupBox Margin="5">
        <StackPanel>

          <RadioButton>Group 1</RadioButton>

//Slider控件 

• 使用户能够通过在刻度尺移动手指光标来改变当前的值。
  
• 有一个默认的Minimum 属性值0 和一个默认的Maximum 属性值10。
  
• 定义了Orientation属性（默认是Horizontal）。
  
• 包含了几个属性，用于调整刻度的位置和频率、ToolTip 的位置和精度（这个ToolTip 是用来显示手指光标移动到了哪个当前值）、决定手指光标是自动贴近刻度值还是平滑地移动到任何值。
  
• 对于键盘导航来说，Slider 包含了Delay 以及Interval 属性，它们与RepeatButton 的同名属性一致。
  
• 要启用刻度，可以把TickPlacement 设定为TopLeft、BottomRight 或者Both。包含了Slider 的方向。
  
• 支持在当前的范围内显示一个更小的范围。
  
• IsSelctionRangeEnabled 被设置为true，可以把SelectionStart 和SelectionEnd 设置为这个“子范围”（subrange）的期望值。
  

<Grid>
      <StackPanel Margin="10">
        <TextBlock Margin="0,0,0,5">Normal Slider (Max=100, Val=10)</TextBlock>
        <Slider Maximum="100" Value="10"></Slider>
        <TextBlock Margin="0,15,0,5">Slider with Tick Marks (TickFrequency=10, TickPlacement=BottomRight)</TextBlock>
        <Slider Maximum="100" Value="10" TickFrequency="10" TickPlacement="BottomRight"></Slider>
        <TextBlock Margin="0,15,0,5">Slider with Irregular Tick Marks (Ticks=0,5,10,15,25,50,100)</TextBlock>
        <Slider Maximum="100" Value="10" Ticks="0,5,10,15,25,50,100"  TickPlacement="BottomRight"></Slider>
        <TextBlock Margin="0,15,0,5" TextWrapping="Wrap">Slider with a Selection Range (IsSelectionRangeEnabled=True, SelectionStart=25, SelectionEnd=75)</TextBlock>
        <Slider Maximum="100" Value="10" TickFrequency="10" TickPlacement="BottomRight"
                IsSelectionRangeEnabled="True" SelectionStart="25" SelectionEnd="75"></Slider>

ProgressBar

• 是当面对长时间运行的操作时，为用户显示一个ProgressBar 可以帮助他们了解具体的进度情况。
• ProgressBar 有一个默认的Minimum 属性0，和一个默认的Maximum 属性100。
• IsIndeterminate —— 当把它设置为true 时，ProgressBar 会显示一段通用的动画（这样，Minimum、Maximum 以及Value 的值不会影响这段动画）。
• Orientation —— 默认为Horizontal，但是也可以被设置为Vertical，可以使进度从下走到上而不是从左走到右。

    <StackPanel Margin="5">
      <ProgressBar Height="10"  IsIndeterminate="True"></ProgressBar>
    </StackPanel>
