ShapeView properties

You will want to customize your shapes. Here is a description of the properties you can modify:

	ShapeType	BorderColor	BorderWidth	CornerRadius	NumberOfPoints	RadiusRatio	Color	ProgressBorderWidth	ProgressBorderColor	Progress	Points
Global Usage	Sets the shape type - Avaible values are Box, Circle, Diamond, Heart, Oval, Progress Circle, Star and Triangle	Sets the border color	Sets the border width	Sets the corner radius	Set the number of points to draw the star	Set the ratio between the inner and the outer radius of the star	Set the fill color	Sets the border width of the circle progress indicator	Sets the border color of the circle progress indicator	Sets the current progress of the circle progress indicator	Sets the list of points of the path
Default value	Box	Color.Black	0	0	5	0.5f	Color.Default	3	Color.Black	0	null
Restrictions	None	Ignored if BorderWidth <= 0 or if 100% transparent	Ignored if <= 0	Ignored if <= 0 and for circles/ovals	Only for stars	Only for stars	Ignored if 100% transparent	Ignored if <= 0	Ignored if 100% transparent	Range from 0 to 100 for clockwise progression - From 0 to -100 for counterclockwise progress	Ignored if null or empty and only for paths

Notes

• As any other ContentView, the ShapeView also exposes HeightRequest, WidthRequest, Padding, Margin, BackgroundColor, HorizontalOptions, VerticalOptions, Rotation, ...

• Be aware that the oval shape relies on its dimensions. If you set equal height and width, a circle will be drawn, so double check your inputs if you get an unexpected result.

Example

You can draw a box with a content Label, responding to touch like so:

var box = new ShapeView
{
	ShapeType = ShapeType.Box,
	HeightRequest = 75,
	WidthRequest = 75,
	Color = Color.Navy,
	HorizontalOptions = LayoutOptions.Center,
	CornerRadius = 5,
	BorderColor = Color.Red,
	BorderWidth = 1f,
	Content = new Label
	{
		Text = "Touch me!",
		FontSize = Device.GetNamedSize(NamedSize.Micro, typeof (Label)),
		TextColor = Color.White,
		HorizontalOptions = LayoutOptions.Fill,
		VerticalOptions = LayoutOptions.Fill,
		VerticalTextAlignment = TextAlignment.Center,
		HorizontalTextAlignment = TextAlignment.Center,
	},
};

var tap = new TapGestureRecognizer
{
	Command = new Command(() => {
		this.DisplayAlert("Touched", "This shape responds to touch!", "Ok");
	})
};

box.GestureRecognizers.Add(tap);
