data GObject Source

A general graphical object containing the common attributes of each Primitive.

Constructors

GObject	Graphical Object
Fields name :: Name Name of the graphical object/element prim :: Primitive The graphical primitive that should be drawn children :: [GObject] Children of the graphical primitive. Can be used to create composited graphical components containing multiple `GObject`s.
Container	A container for Graphical Objects
Fields children :: [GObject] Children of the graphical primitive. Can be used to create composited graphical components containing multiple `GObject`s.

Primitive graphical structures

Constructors

Text	The text graphical primitive
Fields edgeColor :: Color `Color` of the edges of the text edgeThickness :: Float The edge thickness of the text (Should be 1 most of the time) color :: Color The `Color` of the fill of the text position :: Pos The position on the screen of the text size :: Float The height of the text in pixels font :: Font Which font to be used text :: [Char] The actual text to be displayed fromCenter :: Bool Is the position the topleft corner of the text or the center of the text
Line	The line graphical primitive
Fields edgeColor :: Color `Color` of the edges of the text edgeThickness :: Float The edge thickness of the text (Should be 1 most of the time) positions :: [Pos] The list of positions the line should go through. A line will be drawn from point 1 to point 2 to point...
Rect	The rectangle graphical primitive
Fields edgeColor :: Color `Color` of the edges of the text edgeThickness :: Float The edge thickness of the text (Should be 1 most of the time) color :: Color The `Color` of the fill of the text position :: Pos The position on the screen of the text dimensions :: Dimension The dimensions of the rectangle
Arc	The arc graphical primitive. This is the part of a circle. When startAng=0 and endAng=360 you get a full circle.
Fields edgeColor :: Color `Color` of the edges of the text edgeThickness :: Float The edge thickness of the text (Should be 1 most of the time) color :: Color The `Color` of the fill of the text position :: Pos The position on the screen of the text radius :: Float The radius of the arc startAng :: Float The starting angle of the arc in degrees. endAng :: Float The ending angle of the arc in degrees.

Instances

Eq Primitive

type Name = [Char] Source

The name of a graphical object. Another synonym in the package used for this is Element.

type Groupname = [Char] Source

The groupname of a set of graphical objects.

type Color = (Float, Float, Float) Source

The color expressed in (red, green, blue) code where each value is between 0 <= 255.

type Font = [Char] Source

The font associated with a Text primitive.

type Relative = Bool Source

A boolean expressing if an event should be carried out relative to the old situation or to the absolute situation Example of this is when moving an element. Should the move be relative to the old Pos or to the absolute Pos on the screen.
