Synopsis

Documentation

data Arc Source #

The Arc datatype.

Instances

Eq Arc Source #
Methods (==) :: Arc -> Arc -> Bool # (/=) :: Arc -> Arc -> Bool #
Destroyable Arc Source #	An arc item can be destroyed.
Methods destroy :: Arc -> IO () #
Synchronized Arc Source #	You can synchronize on an arc item.
Methods synchronize :: Arc -> IO b -> IO b #
GUIObject Arc Source #	Internal.
Methods toGUIObject :: Arc -> GUIOBJECT Source # cname :: Arc -> String Source # cset :: GUIValue a => Arc -> ConfigID -> a -> IO Arc Source # cget :: GUIValue a => Arc -> ConfigID -> IO a Source #
HasGeometry Arc Source #	An alternative way to specify arc's coords.
Methods geometry :: Geometry -> Config Arc Source # getGeometry :: Arc -> IO Geometry Source #
HasPosition Arc Source #	You can specify the (upper left) position of an arc.
Methods position :: Position -> Config Arc Source # getPosition :: Arc -> IO Position Source #
HasSize Arc Source #	You can specify the size of an arc.
Methods width :: Distance -> Config Arc Source # getWidth :: Arc -> IO Distance Source # height :: Distance -> Config Arc Source # getHeight :: Arc -> IO Distance Source # size :: Size -> Config Arc Source # getSize :: Arc -> IO Size Source #
FilledCanvasItem Arc Source #	An arc is a filled canvas item (it has filling, outline, outline width, and stipple configurations).
Methods filling :: ColourDesignator c => c -> Config Arc Source # getFilling :: Arc -> IO Colour Source # outline :: ColourDesignator c => c -> Config Arc Source # getOutline :: Arc -> IO Colour Source # stipple :: BitMapHandle -> Config Arc Source # getStipple :: Arc -> IO BitMapHandle Source # outlinewidth :: Distance -> Config Arc Source # getOutlineWidth :: Arc -> IO Distance Source #
CanvasItem Arc Source #	An arc is a canvas item (any canvas item is an instance of the abstract `class CanvasItem`).

TaggedCanvasItem Arc Source #	An arc item can have several tags (handlers for a set of canvas items).
Methods tags :: [CanvasTag] -> Config Arc Source #

createArc Source #

Arguments

:: Canvas	the parent canvas.
-> [Config Arc]	the list of configuration options for this arc.
-> IO Arc	An arc item.

Constructs a new arc item.

extent :: Degree -> Config Arc Source #

Sets the length of an arc in counter-clockwise direction.

getExtent :: Arc -> IO Degree Source #

Gets the length of an arc in counter-clockwise direction.

start :: Degree -> Config Arc Source #

Sets the starting angle of an arc.

getStart :: Arc -> IO Degree Source #

Gets the starting angle of an arc.
