TcxCanvas.BeginPath Method

Opens a GDI path bracket for the device context of the underlying canvas.

Declaration

procedure BeginPath;

Remarks

A GDI path is a complex, irregular shape formed by multiple draw calls enclosed between the BeginPath and EndPath procedure calls. You can treat the path as a single primitive or convert it into a region. Call the BeginPath procedure to open a GDI path bracket. Then you can call the following methods to create a path from:

• Circular end elliptical arcs (AngleArc, Arc, and ArcTo).

• Lines (LineTo and Polyline).

• Ellipses (Ellipse).

• Circle or ellipse-based shapes (Chord and Pie).

• Cubic Bezier curves (PolyBezier and PolyBezierTo).

• Rectangles (Rectangle and RoundRect).

• Text (TextOut).

Then, call EndPath to finish the path and select it for the device context of the underlying canvas. This operation destroys the path previously selected for the same context.
