class QtTable t where

A class of types with columns that can be indexed by an integer. A generic implementation is provided for all single constructor types.

Minimal complete definition

Nothing

Methods

getColumn :: Int -> t -> IO QtVariant

class QtField t where

A class of types with columns that can be cast to a QtVariant.

Methods

qtField :: t -> IO QtVariant

Instances

QtField Bool

QtField Double

QtField Int

QtField Integer

Integers are marshalled through QT strings rather than ints.

QtField String

QtField Natural

Naturals are marshalled through QT strings rather than ints.

QtField Text

QtField t => QtField (Maybe t)

Nothing is marshalled as QT null.

class Mock t where

A class that constructs a mock object, with all fields set to undefined, for use with generic implementations that don't actually use the supplied data. Only data types with a single constuctor can have an unambiguous mock object.

Minimal complete definition

Nothing

Methods

mock :: t

Construct a mock object of a data type with a single constructor, with undefined fields.

class CountFields t where

A class of types that have a specific number of fields. Generic implementation is provided for all purely product types.

Minimal complete definition

Nothing

Methods

countFields :: sing t -> Int

class SetupColumns t where

A class of types that can provide a template to setup the QT HaskellModel. A generic implementation is provided for all single constructor types.

Minimal complete definition

Nothing

Methods

setupColumns :: HmDelegateHandle -> sing t -> IO ()

data ColumnIndexException

Exception thrown when QML tries to acces a column that is not available. Shouldn't really happen.

Constructors

ColumnIndexNegative Int

QML called for a negative column index.

ColumnIndexOutOfBounds Int Int

QML called for a column index that is too high.
