Panels

panel :: Gui -> SE () Source #

Renders the GUI elements on the window. Rectangle is calculated automatically (window doesn't listens for keyboard events).

keyPanel :: Gui -> SE () Source #

Renders the GUI elements on the window. Rectangle is calculated automatically (window listens for keyboard events).

tabs :: [(Text, Gui)] -> SE () Source #

Renders the GUI elements with tabs. Rectangles are calculated automatically.

keyTabs :: [(Text, Gui)] -> SE () Source #

Renders the GUI elements with tabs. Rectangles are calculated automatically.

panels :: [Gui] -> SE () Source #

Renders a list of panels.

keyPanels :: [Gui] -> SE () Source #

Renders a list of panels. Panels are sensitive to keyboard events.

panelBy :: Text -> Maybe Rect -> Gui -> SE () Source #

Renders the GUI elements on the window. We can specify the window title and rectangle of the window.

keyPanelBy :: Text -> Maybe Rect -> Gui -> SE () Source #

Renders the GUI elements on the window. We can specify the window title and rectangle of the window. Panesls are sensitive to keyboard events.

tabsBy :: Text -> Maybe Rect -> [(Text, Maybe Rect, Gui)] -> SE () Source #

Renders the GUI elements with tabs. We can specify the window title and rectangles for all tabs and for the main window.

keyTabsBy :: Text -> Maybe Rect -> [(Text, Maybe Rect, Gui)] -> SE () Source #

Renders the GUI elements with tabs. We can specify the window title and rectangles for all tabs and for the main window. Tabs are sensitive to keyboard events.

Types

noInner :: Inner Source #

A value for stateless widgets.

type Widget a b = SE (Gui, Output a, Input b, Inner) Source #

A widget consists of visible element (Gui), value consumer (Output) and producer (Input) and an inner state (Inner).

widget :: SE (Gui, Output a, Input b, Inner) -> Widget a b Source #

A widget constructor.

type Source a = SE (Gui, Input a) Source #

A producer of the values.

source :: SE (Gui, Input a) -> Source a Source #

A producer constructor.

type Sink a = SE (Gui, Output a) Source #

A consumer of the values.

sink :: SE (Gui, Output a) -> Sink a Source #

A consumer constructor.

type Display = SE Gui Source #

A static element. We can only look at it.

display :: SE Gui -> Display Source #

A display constructor.

type SinkSource a = SE (Gui, Output a, Input a) Source #

sinkSource :: SE (Gui, Output a, Input a) -> SinkSource a Source #

sourceSlice :: SinkSource a -> Source a Source #

sinkSlice :: SinkSource a -> Sink a Source #

mapSource :: (a -> b) -> Source a -> Source b Source #

A handy function for transforming the value of producers.

mapGuiSource :: (Gui -> Gui) -> Source a -> Source a Source #

A handy function for transforming the GUIs of producers.

mhor :: Monoid a => [Source a] -> Source a Source #

Horizontal grouping of widgets that can produce monoidal values.

mver :: Monoid a => [Source a] -> Source a Source #

Vertical grouping of widgets that can produce monoidal values.

msca :: Double -> Source a -> Source a Source #

Scaling of widgets that can produce values.

Widgets

count :: ValDiap -> ValStep -> Maybe ValStep -> Double -> Source (Evt D) Source #

Allows the user to increase/decrease a value with mouse clicks on a corresponding arrow button. Output is an event stream that contains values when counter changes.

count diapason fineValStep maybeCoarseValStep initValue

doc: http://www.csounds.com/manual/html/FLcount.html

countSig :: ValDiap -> ValStep -> Maybe ValStep -> Double -> Source Sig Source #

A variance on the function count, but it produces a signal of piecewise constant function.

joy :: ValSpan -> ValSpan -> (Double, Double) -> Source (Sig, Sig) Source #

It is a squared area that allows the user to modify two output values at the same time. It acts like a joystick.

joy valueSpanX valueSpanY (initX, initY)

doc: http://www.csounds.com/manual/html/FLjoy.html

knob :: Text -> ValSpan -> Double -> Source Sig Source #

A FLTK widget opcode that creates a knob.

roller :: Text -> ValSpan -> ValStep -> Double -> Source Sig Source #

FLroller is a sort of knob, but put transversally.

slider :: Text -> ValSpan -> Double -> Source Sig Source #

FLslider puts a slider into the corresponding container.

slider valueSpan initVal

doc: http://www.csounds.com/manual/html/FLslider.html

sliderBank :: Text -> [Double] -> Source [Sig] Source #

Constructs a list of linear unit sliders (ranges in [0, 1]). It takes a list of init values.

numeric :: Text -> ValDiap -> ValStep -> Double -> Source Sig Source #

numeric (originally FLtext in the Csound) allows the user to modify a parameter value by directly typing it into a text field.

numeric diapason step initValue

doc: http://www.csounds.com/manual/html/FLtext.html

meter :: Text -> ValSpan -> Double -> Sink Sig Source #

A slider that serves as indicator. It consumes values instead of producing.

meter valueSpan initValue

box :: Text -> Display Source #

A FLTK widget that displays text inside of a box. If the text is longer than 255 characters the text is split on several parts (Csound limitations).
