Methods

getName

data MenuLinkIterGetNameMethodInfo

Instances

((~) * signature (m Text), MonadIO m, IsMenuLinkIter a) => MethodInfo * MenuLinkIterGetNameMethodInfo a signature

Methods

overloadedMethod :: MethodProxy MenuLinkIterGetNameMethodInfo a -> signature -> s

menuLinkIterGetName

Arguments

:: (HasCallStack, MonadIO m, IsMenuLinkIter a)

=> a

iter: a MenuLinkIter

-> m Text

Returns: the type of the link

Gets the name of the link at the current iterator position.

The iterator is not advanced.

Since: 2.32

getNext

data MenuLinkIterGetNextMethodInfo

Instances

((~) * signature (m (Bool, Text, MenuModel)), MonadIO m, IsMenuLinkIter a) => MethodInfo * MenuLinkIterGetNextMethodInfo a signature

Methods

overloadedMethod :: MethodProxy MenuLinkIterGetNextMethodInfo a -> signature -> s

menuLinkIterGetNext

Arguments

:: (HasCallStack, MonadIO m, IsMenuLinkIter a)

=> a

iter: a MenuLinkIter

-> m (Bool, Text, MenuModel)

Returns: True on success, or False if there is no additional link

This function combines menuLinkIterNext with menuLinkIterGetName and menuLinkIterGetValue.

First the iterator is advanced to the next (possibly first) link. If that fails, then False is returned and there are no other effects.

If successful, outLink and value are set to the name and MenuModel of the link that has just been advanced to. At this point, menuLinkIterGetName and menuLinkIterGetValue will return the same values again.

The value returned in outLink remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using objectUnref when it is no longer in use.

Since: 2.32

getValue

data MenuLinkIterGetValueMethodInfo

Instances

((~) * signature (m MenuModel), MonadIO m, IsMenuLinkIter a) => MethodInfo * MenuLinkIterGetValueMethodInfo a signature

Methods

overloadedMethod :: MethodProxy MenuLinkIterGetValueMethodInfo a -> signature -> s

menuLinkIterGetValue

Arguments

:: (HasCallStack, MonadIO m, IsMenuLinkIter a)

=> a

iter: a MenuLinkIter

-> m MenuModel

Returns: the MenuModel that is linked to

Gets the linked MenuModel at the current iterator position.

The iterator is not advanced.

Since: 2.32

next

data MenuLinkIterNextMethodInfo

Instances

((~) * signature (m Bool), MonadIO m, IsMenuLinkIter a) => MethodInfo * MenuLinkIterNextMethodInfo a signature

Methods

overloadedMethod :: MethodProxy MenuLinkIterNextMethodInfo a -> signature -> s

menuLinkIterNext

Arguments

:: (HasCallStack, MonadIO m, IsMenuLinkIter a)

=> a

iter: a MenuLinkIter

-> m Bool

Returns: True on success, or False when there are no more links

Attempts to advance the iterator to the next (possibly first) link.

True is returned on success, or False if there are no more links.

You must call this function when you first acquire the iterator to advance it to the first link (and determine if the first link exists at all).
