我需要写一个控制,这将是这样的:不能得到正确的标签尺寸
问题是,我不能让标签的实际尺寸重绘我的矩形几何形状。标签的高度总是比真正占据屏幕的空间大得多。我不知道该怎么办。这里是代码:
<Popup x:Class="Controls.Callout"
x:ClassModifier="internal"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" >
<Grid>
<Image>
<Image.Source>
<DrawingImage>
<DrawingImage.Drawing >
<GeometryDrawing Brush="Orange" x:Name="geometryDrawing">
<GeometryDrawing.Pen>
<Pen Brush="Black" Thickness="2"/>
</GeometryDrawing.Pen>
<GeometryDrawing.Geometry>
<CombinedGeometry GeometryCombineMode="Union">
<CombinedGeometry.Geometry1>
<RectangleGeometry x:Name="rectangel"
RadiusX="15" RadiusY="15"
Rect="0,30, 300,100"
/>
</CombinedGeometry.Geometry1>
<CombinedGeometry.Geometry2>
<PathGeometry>
<PathFigure StartPoint="30,30" IsClosed="False">
<PolyLineSegment Points="15,0, 90,30"/>
</PathFigure>
</PathGeometry>
</CombinedGeometry.Geometry2>
</CombinedGeometry>
</GeometryDrawing.Geometry>
</GeometryDrawing>
</DrawingImage.Drawing>
</DrawingImage>
</Image.Source>
</Image>
<Label Padding="5 20" MaxWidth="300" Name="myLabel" FontSize="16" >
<!--Content="{Binding}">-->
<!--MaxHeight="100" MaxWidth="300">-->
<AccessText TextWrapping="Wrap" MaxHeight="50"/>
</Label>
</Grid>
</Popup>
后面的代码:
internal partial class Callout : Popup
{
public Callout()
{
InitializeComponent();
}
protected override void OnOpened(System.EventArgs e)
{
rectangel = new RectangleGeometry(new Rect(0,30,300, myLabel.Height/2));
}
}
我试图这样: <! - 这里将指针 - > <矩形半径X = “150” 半径= “150”/> 但它不起作用。请你能提供一个你的意思的例子吗? –

谢谢,你帮了我很多! – Seekeer 2011-04-04 15:49:10
