Documentation

data CanvFrame Source

A CanvFrame represents (indirectly, through cfRoot, and we access to the graph which is provided by the VCanvas) a subgraph such as the expression tree of a function which is being edited or called. Constructors CanvFrame cfHeader :: TextBox top area of the frame cfFooter :: TextBox bottom area cfVarNames :: [String] variable (parameter) names cfParent :: Maybe Node the node opened to make this frame cfFrameNode :: Node this frame as a node in the graph; also serves as the ID of the frame. cfEnv :: Env environment for evaluation cfBox :: BBox box of the whole frame (header, tree, and footer) cfLevel :: Double 0 = bottom level, 1 = next higher, etc. cfFunctoid :: Functoid includes tlo for an edit frame frameType :: FrameType edit or call frame Instances Eq CanvFrame Show CanvFrame

data FrameType Source

Constructors EditFrame CallFrame Instances Eq FrameType Read FrameType Show FrameType

argIoletCounter :: [String] -> ExprNode -> (Int, Int) Source

argIoletCounter returns (no. of inlets, no. of outlets) derived from the argument list of a function still being defined

atLeastSizeFrame :: Size -> CanvFrame -> CanvFrame Source

cfEvalReady :: CanvFrame -> Bool Source

A frame is eval ready -- that is, okay to run the Eval Frame dialog -- if it is a call frame with no parent

cfPointInHeader :: CanvFrame -> Double -> Double -> Bool Source

cfPointInFooter :: CanvFrame -> Double -> Double -> Bool Source

cfRoot :: CanvFrame -> Node Source

The root of the tree displayed in the frame

frameNewWithLayout :: Style -> Position -> Double -> Functoid -> Maybe [Value] -> FrameType -> Node -> Env -> Maybe Node -> (CanvFrame, FunctoidLayout) Source

Figure out the frame layout for a function. Returns the layout and frame. Currently, the frame is marked as a call frame; if you want to edit it, call (editFrame? editFunction?)

frameBodyBox :: CanvFrame -> BBox Source

frameNodeAt :: CanvFrame -> WGraph -> Position -> Maybe Node Source

frameOffset :: Style -> CanvFrame -> Position Source

Where to position a new frame that is grown out of an old frame? This is a very rough draft of frameOffset

levelOrder :: CanvFrame -> CanvFrame -> Ordering Source

Use levelOrder for sorting frames before drawing them

nodeCompoundFunction :: WGraph -> CanvFrame -> Node -> Maybe Function Source

pointIolet :: Position -> Int -> [Iolet] -> Maybe Int Source

resizeFrame :: CanvFrame -> Double -> Double -> CanvFrame Source

translateFrame :: CanvFrame -> Double -> Double -> CanvFrame Source

grTranslateFrameNodes :: WGraph -> CanvFrame -> Double -> Double -> WGraph Source
