class GOval : public GObject

This graphical object subclass represents an oval inscribed in a rectangular box. For example, the following code displays a filled green oval inscribed in the graphics window: 
   int main() {
      GWindow gw;
      cout << "This program draws a green oval filling the window." << endl;
      GOval *oval = new GOval(gw.getWidth(), gw.getHeight());
      oval->setFilled(true);
      oval->setColor("GREEN");
      gw.add(oval);
      return 0;
   }

Constructor detail

GOval(double width, double height);
GOval(double x, double y, double width, double height);
Constructs a new oval inscribed in the specified rectangle. The first form is positioned at the origin; the second at the coordinates given by x and y.

Usage:

GOval *oval = new GOval(width, height);
GOval *oval = new GOval(x, y, width, height);

Method detail

void setSize(const GDimension & size);
void setSize(double width, double height);
Changes the size of the bounding rectangle to the specified width and height.

Usage:

oval->setSize(size);
oval->setSize(width, height);

void setBounds(const GRectangle & size);
void setBounds(double x, double y, double width, double height);
Changes the bounds of the oval to the specified values.

Usage:

oval->setBounds(rect);
oval->setBounds(x, y, width, height);

void setFilled(bool flag);
Sets the fill status for the oval, where false is outlined and true is filled.

Usage:

oval->setFilled(flag);

bool isFilled() const;
Returns true if the oval is filled.

Usage:

if (oval->isFilled()) ...

void setFillColor(string color);
void setFillColor(int rgb);
Sets the color used to display the filled region of this oval.

Usage:

oval->setFillColor(color);

string getFillColor() const;
Returns the color used to display the filled region of this oval. If none has been set, getFillColor returns the empty string.
