color: Integer);
The drawPie method of the Window class draws a pie-shaped wedge on a form or control, using a colored pen the width of the drawWidth property, the style of the drawStyle property, and the mode of the drawMode property. The wedge is an elliptical arc whose center and two end points are joined by lines. If this method is not called from a paint event, set the autoRedraw property to true.
The figure is filled using the color and style of the drawFillColor and drawFillStyle properties of the object.
The drawPie method parameters are listed in the following table.
| Parameter | Description |
|---|---|
| x1, y1, x2, y2 | Rectangle bounding the ellipse of which the pie is a part |
| startX, startY | Logical x and y (horizontal and vertical) coordinates of the point that defines the starting point of the arc |
| endX, endY | Logical x and y coordinates of the point that defines the end point of the arc |
| color | Color of the pen used |
The position units of the parameters are
The startX, startY, endX, and endY parameter points do not need to lie exactly on the arc.
The starting point of the arc is the point at which a ray drawn from the center of the bounding rectangle through the specified starting point intersects the ellipse. The end point of the arc is the point at which a ray drawn from the center of the bounding rectangle through the specified end point intersects the ellipse.
The figure drawn by this function extends up to but does not include the right and bottom coordinates, so that the height of the figure is y2 through y1 and the width is x2 through x1. The arc is drawn in a counterclockwise direction.
The width and height of a rectangle must each be in the range 2 units through 32,767 units.
