Description
Draws a rectangle on the canvas.
Override the Rectangle method to implement drawing a rectangle using the pen and fill it with the current brush. Specify the rectangle's coordinates in one of two ways:
- Giving four coordinates that define the upper-left corner at the point (X1, Y1) and the lower-right corner at the point (X2, Y2).
- Using a TRect type.
To fill a rectangular region without drawing the boundary in the current pen, use FillRect. To outline a rectangular region without filling it, use FrameRect or Polygon. To draw a rectangle with rounded corners, use RoundRect.
