Exempel

I följande exempel visas hur du använder CustomLineCap konstruktorn. Om du vill köra det här exemplet klistrar du in koden i ett Windows formulär. Hantera formulärets Paint händelse och anropa DrawCaps från formulärets Paint händelsehanteringsmetod och skicka e som PaintEventArgs.

protected void DrawCaps(PaintEventArgs e)
{
    GraphicsPath hPath = new GraphicsPath();

    // Create the outline for our custom end cap.
    hPath.AddLine(new Point(0, 0), new Point(0, 5));
    hPath.AddLine(new Point(0, 5), new Point(5, 1));
    hPath.AddLine(new Point(5, 1), new Point(3, 1));

    // Construct the hook-shaped end cap.
    CustomLineCap HookCap = new CustomLineCap(null, hPath);

    // Set the start cap and end cap of the HookCap to be rounded.
    HookCap.SetStrokeCaps(LineCap.Round, LineCap.Round);

    // Create a pen and set end custom start and end
    // caps to the hook cap.
    Pen customCapPen = new Pen(Color.Black, 5);
    customCapPen.CustomStartCap = HookCap;
    customCapPen.CustomEndCap = HookCap;

    // Create a second pen using the start and end caps from
    // the hook cap.

    LineCap endCap;

Kommentarer

CustomLineCap använder ett fyllningsläge med "lindning" oavsett fyllningsläget som angetts för åtgärden.

Parametrarna fillPath och strokePath kan inte användas samtidigt. En parameter måste skickas ett null-värde. Om ingen av parametrarna skickas ett null-värde fillPath ignoreras. Om strokePath är nullska , fillPath fånga upp den negativa y-axeln.
