Description
This module provides general support for user interface components.
A user interface component is either a user interface item or a user interface circuit. UI items are introduced by Graphics.UI.Grapefruit.Item and UI circuits by Graphics.UI.Grapefruit.Circuit.

Documentation
class UIComp uiComp whereSource
The class of all user interface components.
A user interface component is a part of a user interface which communicates with the remainder of the user interface through signals.
Methods
(|>>) :: Circuit era i tmp -> uiComp item uiBackend era tmp o -> uiComp item uiBackend era i oSource
Adds a circuit before a user interface component.
This does not add any items to the user interface but may add data manipulation and control functionality.
(>>|) :: uiComp item uiBackend era i tmp -> Circuit era tmp o -> uiComp item uiBackend era i oSource
Adds a circuit after a user interface component.
This does not add any items to the user interface but may add data manipulation and control functionality.
loop :: uiComp item uiBackend era (i, feedback) (o, feedback) -> uiComp item uiBackend era i oSource
Adds a feedback loop to a user interface component.
This method is completely analogous to the loop method of ArrowLoop. It is
provided because not every instance of UIComp is an arrow.
toUICircuit :: uiComp item uiBackend era i o -> UICircuit item uiBackend era i oSource
Converts a user interface component into a user interface circuit.
fromUIItem :: UIItem item uiBackend era i o -> uiComp item uiBackend era i oSource
Converts a user interface item into a user interface component.
(<<|) :: UIComp uiComp => uiComp item uiBackend era tmp o -> Circuit era i tmp -> uiComp item uiBackend era i oSource
Puts a circuit before a user interface component.
This does not add any items to the user interface but may add data manipulation and control
functionality. (<<|) is equivalent to flip (.
|>>)
(|<<) :: UIComp uiComp => Circuit era tmp o -> uiComp item uiBackend era i tmp -> uiComp item uiBackend era i oSource
Puts a circuit after a user interface component.
This does not add any items to the user interface but may add data manipulation and control
functionality. (|<<) is equivalent to flip (.
