toFlowBoxChild :: (MonadIO m, IsFlowBoxChild o) => o -> m FlowBoxChild Source #
Cast to FlowBoxChild, for types for which this is known to be safe. For general casts, use castTo.

A convenience alias for Nothing :: Maybe FlowBoxChild.
Methods
Overloaded methods
changed
Arguments
| :: (HasCallStack, MonadIO m, IsFlowBoxChild a) | |
| => a |
|
| -> m () |
Marks child as changed, causing any state that depends on this
to be updated. This affects sorting and filtering.
Note that calls to this method must be in sync with the data
used for the sorting and filtering functions. For instance, if
the list is mirroring some external data set, and *two* children
changed in the external data set when you call
flowBoxChildChanged on the first child, the sort function
must only read the new data for the first of the two changed
children, otherwise the resorting of the children will be wrong.
This generally means that if you don’t fully control the data
model, you have to duplicate the data that affects the sorting
and filtering functions into the widgets themselves. Another
alternative is to call flowBoxInvalidateSort on any
model change, but that is more expensive.

getIndex
Arguments
| :: (HasCallStack, MonadIO m, IsFlowBoxChild a) | |
| => a |
|
| -> m Int32 | Returns: the index of the |
Gets the current index of the child in its FlowBox container.
Since: 3.12
isSelected
flowBoxChildIsSelected Source #
Arguments
| :: (HasCallStack, MonadIO m, IsFlowBoxChild a) | |
| => a |
|
| -> m Bool | Returns: |
Returns whether the child is currently selected in its
FlowBox container.
Since: 3.12
new
Arguments
| :: (HasCallStack, MonadIO m) | |
| => m FlowBoxChild | Returns: a new |
Creates a new FlowBoxChild, to be used as a child
of a FlowBox.

Signals
activate
type C_FlowBoxChildActivateCallback = Ptr () -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type FlowBoxChildActivateCallback = IO () Source #
afterFlowBoxChildActivate :: (IsFlowBoxChild a, MonadIO m) => a -> FlowBoxChildActivateCallback -> m SignalHandlerId Source #
Connect a signal handler for the activate signal, to be run after the default handler. When overloading is enabled, this is equivalent to
after flowBoxChild #activate callback
genClosure_FlowBoxChildActivate :: MonadIO m => FlowBoxChildActivateCallback -> m (GClosure C_FlowBoxChildActivateCallback) Source #
Wrap the callback into a GClosure.
mk_FlowBoxChildActivateCallback :: C_FlowBoxChildActivateCallback -> IO (FunPtr C_FlowBoxChildActivateCallback) Source #
Generate a function pointer callable from C code, from a C_FlowBoxChildActivateCallback.
noFlowBoxChildActivateCallback :: Maybe FlowBoxChildActivateCallback Source #
A convenience synonym for Nothing :: Maybe FlowBoxChildActivateCallback
onFlowBoxChildActivate :: (IsFlowBoxChild a, MonadIO m) => a -> FlowBoxChildActivateCallback -> m SignalHandlerId Source #
Connect a signal handler for the activate signal, to be run before the default handler. When overloading is enabled, this is equivalent to
on flowBoxChild #activate callback
