Eq Polygon

Methods

(==) :: Polygon -> Polygon -> Bool

(/=) :: Polygon -> Polygon -> Bool

Destroyable Polygon

An polygon item can be destroyed.

Methods

destroy :: Polygon -> IO ()

Synchronized Polygon

You can synchronize on a polygon item.

Methods

synchronize :: Polygon -> IO b -> IO b

GUIObject Polygon

Internal.

Methods

toGUIObject :: Polygon -> GUIOBJECT

cname :: Polygon -> String

FilledCanvasItem Polygon

A polygon item is a filled canvas item (it has filling, outline, outline width, and stipple configurations).

Methods

filling :: ColourDesignator c => c -> Config Polygon

getFilling :: Polygon -> IO Colour

outline :: ColourDesignator c => c -> Config Polygon

getOutline :: Polygon -> IO Colour

stipple :: BitMapHandle -> Config Polygon

getStipple :: Polygon -> IO BitMapHandle

outlinewidth :: Distance -> Config Polygon

getOutlineWidth :: Polygon -> IO Distance

CanvasItem Polygon

A polygon item is a canvas item (any canvas item is an instance of the abstract class CanvasItem).

TaggedCanvasItem Polygon

A polygon item can have several tags (handlers for a set of canvas items).

Methods

tags :: [CanvasTag] -> Config Polygon

createPolygon

Arguments

:: Canvas

the parent canvas.

-> [Config Polygon]

the list of configuration options for this polygon item.

-> IO Polygon

A polygon item.

Constructs a new polygon item.
