Methods

enumValueRowName

enumValueRowName Source #

Arguments

:: (HasCallStack, MonadIO m, IsEnumValueObject a)
=> a	`value`: the value from the enum from which to get a name
-> Ptr ()	`userData`: unused user data
-> m Text	Returns: a newly allocated displayable name that represents `value`

This is a default implementation of ComboRowGetEnumValueNameFunc to be used with comboRowSetForEnum. If the enumeration has a nickname, it will return it, otherwise it will return its name.

Since: 0.0.6

init

init Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Maybe [Text]	`argv`: Address of the <parameter>argv</parameter> parameter of `main()`, or `Nothing`. Any options understood by Handy are stripped before return.
-> m (Bool, Maybe [Text])	Returns: `True` if initialization was successful, `False` otherwise.

Call this function before using any other Handy functions in your GUI applications. If libhandy has already been initialized, the function will simply return without processing the new arguments.

listBoxSeparatorHeader

listBoxSeparatorHeader Source #

Arguments

:: (HasCallStack, MonadIO m, IsListBoxRow a, IsListBoxRow b)
=> a	`row`: the row to update
-> Maybe b	`before`: the row before `row`, or `Nothing` if it is first
-> Ptr ()	`unusedUserData`: unused user data
-> m ()

Separates rows by using Separator as headers. The first row doesn't have a separator as there is no row above it.

Since: 0.0.6

stringUtf8Len

stringUtf8Len Source #

Arguments

:: (HasCallStack, MonadIO m)
=> String	`string`: a `String`
-> m CLong	Returns: the length of `string` in characters

Computes the length of the string in utf-8 characters. See g_utf8_strlen.

stringUtf8Truncate

stringUtf8Truncate Source #

Arguments

:: (HasCallStack, MonadIO m)
=> String	`string`: a `String`
-> Word64	`len`: the new size of the string
-> m String	Returns: `string`

Cut of the end of the string string so that len utf8 characters remain
