我有一个Label控件,我现在要对它设置ControlTemplate以重新呈现它的外观,代码如下
<ControlTemplate TargetType="Label" x:Key="PopFrame">
<Border Width="{TemplateBinding Label.Width}" Height="{TemplateBinding Label.Height}" CornerRadius="5" Background="{DynamicResource PopFrameRectangle1}" BitmapEffect="{DynamicResource PopEffect1}" Padding="5">
<Grid>
<Border CornerRadius="5" Padding="0,10,0,0" Background="{DynamicResource PopBrush1}">
<Rectangle RadiusX="5" RadiusY="5" Fill="{DynamicResource PopBrush2}" />
</Border>
<Path Name="mPath" Stretch="Fill" Stroke="#FF43B7FF" Fill="#FFFFFFFF" />
<Border Padding="15,45,15,15">
<Rectangle Fill="White" RadiusX="5" RadiusY="5" Stroke="#FFA19FA0" StrokeThickness="1" />
</Border>
</Grid>
</Border>
</ControlTemplate>
现在的问题是,中间的mPath的Data属性,是一堆的曲线,这些曲线的各个点,是要根据Label.Width和Label.Height来决定的,这里经常要用到Label.Width - 5 这样的操作,这种操作在CS代码里做是毫无问题的,但是在XAML里,该要如何实现呢?
附Data属性点设置代码
StreamGeometry geometry = new StreamGeometry();
geometry.FillRule = FillRule.Nonzero; //声前F0还是F1,现在是F1
using (StreamGeometryContext ctx = geometry.Open())
{
ctx.BeginFigure(new Point(5, 0), true, true);
ctx.LineTo(new Point(titlewidth, 0), true, false);
ctx.BezierTo(new Point(titlewidth + 28, 0), new Point(titlewidth + 4, 27), new Point(titlewidth + 60, 27), true, false);
ctx.LineTo(new Point(width, 27), true, false);
ctx.BezierTo(new Point(width + 2.5, 27), new Point(width + 5, 29.5), new Point(width + 5, 32), true, false);
ctx.LineTo(new Point(width + 5, height), true, false);
ctx.BezierTo(new Point(width + 5, height + 2.5), new Point(width + 2.5, height + 5), new Point(width, height + 5), true, false);
ctx.LineTo(new Point(5, height + 5), true, false);
ctx.BezierTo(new Point(2.5, height + 5), new Point(0, height + 2.5), new Point(0, height), true, false);
ctx.LineTo(new Point(0, 5), true, false);
ctx.BezierTo(new Point(0, 2.5), new Point(2.5, 0), new Point(5, 0), true, false);
}
geometry.Freeze();
