void setHeight(int height)

Sets the height of the editor window.

void setWidth(int width)

Set the width of the editor window.

void setBackgroundImage(String imageFile)

Sets the background of the editor window to the image contained in imageFile.

void add(element)

Adds the given element to be displayed in the editor window.

Text class

Text(String text, int x, int y)

Creates a Text object representing text to be displayed at position (x, y).

Text(Text textObject)

Creates a Text object which is a copy of textObject.

void setFont(String font_name, int font_style, int font_size)

Sets the font to be used to display the text.

Description: Possible values for font_style:

1 = Bold

2 = Italic

3 = Bold and Italic

Any other value = Plain

void setColor(int red, int green, int blue)

Sets the color to be used to display the text. The range of each value for RGB is 0 to 255.

void translate(int d_x, int d_y)

Relocates the Text object by d_x units along the X-axis and d_y units along the Y-axis.

(positive value for x/y to the right/downward, negative value for x/y- to the left / upward)


2/4

Line class

Line(int x1,int y1, int x2, int y2)

Creates a Line object representing a line with endpoints (x1,y1) and (x2,y2).

Line(Line lineObject)Creates a Line object which is a copy of lineObject.


Sets the color to be used to display the line. The range of each value for RGB is 0 to 255.


Relocates the Line object by d_x units along the X-axis and d_y units along the Y-axis.


Rectangle class

Rectangle(int x, int y , int width , int height)

Creates a Rectangle object representing a rectangle shape given the upper-left corner (x,y), width

and height

Rectangle(Rectangle rectObject)

Creates a Rectangle object which is a copy of rectObject

Void setHollow(bool status)

Sets the hollow status of the shape. If the hollow status is true, the shape displayed is unfilled

i.e. only its border is displayed. Otherwise, the shape displayed is filled.

By default, the hollow status of a newly created Rectangle object is true.


Sets the color to be used to display the rectangle. The range of each value for RGB is 0 to 255.

Void setHollow(bool status)




void setColor(int red, int green, int blue)Sets the color to be used to display the oval. The range of each value for RGB is 0 to 255.


Relocates the Oval object by d_x units along the X-axis and d_y units along the Y-axis.


Polygon class

Polygon(int numPoints)Creates a Polygon object representing a closed polygonal shape consisting of n vertices.

An example of a polygon containing 5 vertices

Polygon(Polygon polygonObject)

Creates a Polygon object which is a copy of polygonObject.

void setVertex(int idx, int x, int y)

Sets the X and Y coordinates of the idx-th vertex of the polygon to x and y respectively

The index of the vertex whose value must be between 0 and numVerts-1 where numVerts isthe number of vertices of the polygon.

void setHollow(bool status)





4/4


Sets the color to be used to display the polygon. The range of each value for RGB is 0 to 255.


Relocates the Polygon object by d_x units along the X-axis and d_y units along the Y-axis.


Group class

Group()

Creates an Group object representing an empty group of elements.Group(Group groupObject)

Creates a Group object which is a copy of groupObject.

void add(element)

Adds the given element to the group
