The main difference between these classes is that a Shape has a brush associated with it and can be rendered to the screen, and a Geometry simply defines a region of space and is not rendered unless it helps contribute information to another UI property. A Border also has the option of having rounded corners if you set the CornerRadius property. The next example creates a Polygon with 4 points set to 10, , 60, , , , and ,
The next example creates a Rectangle with a Width of and a Height of In code-behind, you use a PointCollection to define the points and you add each individual point as a Point structure to the collection.
The next example creates a Rectangle with a Width of and a Height of In XAML, you define the points with a comma-separated list.
A Border also has the option of having rounded corners if you set the CornerRadius property. A Line ignores any value provided for Fill , because it has no interior space.
Add rectangleGeometry1 ; geometryGroup1. Add line1 ; Polyline A Polyline is similar to a Polygon in that the boundary of the shape is defined by a set of points, except the last point in a Polyline is not connected to the first point.
For more info about brushes, see Using brushes. You can round the corners of a Rectangle.
But with this versatility comes complexity. For example, a Point is part of the event data for touch events, so you can know exactly where in a coordinate space the touch action occurred. Point 10, ; points.
We set the StrokeThickness to 3. Polygon A Polygon is a shape with a boundary defined by an arbitrary number of points. You could then use a TranslateTransform to move the entire Line, if you wanted it to start at a point other than 0,0.
Add rectangleGeometry1 ; geometryGroup1. There are two techniques for setting Data: The example is mainly intended to give you some examples of what elements exist in the Path.
If you do not specify a Fill, then the Polyline is similar to what would have rendered if you had specified several individual Line elements where the start points and end points of consecutive lines intersected. This segment is indicated by the "C" command in the Data attribute string. The most common reason for doing this is because you want to use one or more of the curves and complex shapes that can be defined as Segments values for a PathFigure , for example BezierSegment.
You can set the Data property to a single Geometry object. In code-behind you use a PointCollection to define the points and you add each individual point as a Point value to the collection.
This Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. You define the geometry of a path with the Data property. These properties specify the x-axis and y-axis of an ellipse that defines the curve of the corners.
You can round the corners of a Rectangle. A Line ignores any value provided for Fill , because it has no interior space. Polygon A Polygon is a shape with a boundary defined by an arbitrary number of points.
Fill and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush with it. This enables minimal markup for horizontal or vertical lines. You can set the Data property to a single Geometry object.
