GI.Gtk.Objects.FlowBox

A GtkFlowBox positions child widgets in sequence according to its orientation.

For instance, with the horizontal orientation, the widgets will be arranged from left to right, starting a new row under the previous row when necessary. Reducing the width in this case will require more rows, so a larger height will be requested.

Likewise, with the vertical orientation, the widgets will be arranged from top to bottom, starting a new column to the right when necessary. Reducing the height will require more columns, so a larger width will be requested.

The size request of a GtkFlowBox alone may not be what you expect; if you need to be able to shrink it along both axes and dynamically reflow its children, you may have to wrap it in a ScrolledWindow to enable that.

The children of a GtkFlowBox can be dynamically sorted and filtered.

Although a GtkFlowBox must have only FlowBoxChild children, you can add any kind of widget to it via containerAdd, and a GtkFlowBoxChild widget will automatically be inserted between the box and the widget.

Also see ListBox.

GtkFlowBox was added in GTK+ 3.12.

Methods

bindModel

flowBoxBindModel

Arguments

:: (HasCallStack, MonadIO m, IsFlowBox a, IsListModel b)

=> a

box: a FlowBox

-> Maybe b

model: the ListModel to be bound to box

-> FlowBoxCreateWidgetFunc

createWidgetFunc: a function that creates widgets for items

-> m ()

Binds model to box.

If box was already bound to a model, that previous binding is destroyed.

The contents of box are cleared and then filled with widgets that represent items from model. box is updated whenever model changes. If model is Nothing, box is left empty.

It is undefined to add or remove widgets directly (for example, with flowBoxInsert or containerAdd) while box is bound to a model.

Note that using a model is incompatible with the filtering and sorting functionality in GtkFlowBox. When using a model, filtering and sorting should be implemented by the model.

onFlowBoxToggleCursorChild :: (IsFlowBox a, MonadIO m) => a -> FlowBoxToggleCursorChildCallback -> m SignalHandlerId

Connect a signal handler for the toggleCursorChild signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on flowBox #toggleCursorChild callback

wrap_FlowBoxToggleCursorChildCallback :: FlowBoxToggleCursorChildCallback -> C_FlowBoxToggleCursorChildCallback

Wrap a FlowBoxToggleCursorChildCallback into a C_FlowBoxToggleCursorChildCallback.

unselectAll

type C_FlowBoxUnselectAllCallback = Ptr () -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type FlowBoxUnselectAllCallback = IO ()

The unselectAll signal is a [keybinding signal][GtkBindingSignal] which gets emitted to unselect all children of the box, if the selection mode permits it.

The default bindings for this signal is Ctrl-Shift-a.

afterFlowBoxUnselectAll :: (IsFlowBox a, MonadIO m) => a -> FlowBoxUnselectAllCallback -> m SignalHandlerId

Connect a signal handler for the unselectAll signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after flowBox #unselectAll callback

genClosure_FlowBoxUnselectAll :: MonadIO m => FlowBoxUnselectAllCallback -> m (GClosure C_FlowBoxUnselectAllCallback)

Wrap the callback into a GClosure.

mk_FlowBoxUnselectAllCallback :: C_FlowBoxUnselectAllCallback -> IO (FunPtr C_FlowBoxUnselectAllCallback)

Generate a function pointer callable from C code, from a C_FlowBoxUnselectAllCallback.

noFlowBoxUnselectAllCallback :: Maybe FlowBoxUnselectAllCallback

A convenience synonym for Nothing :: Maybe FlowBoxUnselectAllCallback.

onFlowBoxUnselectAll :: (IsFlowBox a, MonadIO m) => a -> FlowBoxUnselectAllCallback -> m SignalHandlerId

Connect a signal handler for the unselectAll signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on flowBox #unselectAll callback

wrap_FlowBoxUnselectAllCallback :: FlowBoxUnselectAllCallback -> C_FlowBoxUnselectAllCallback

Wrap a FlowBoxUnselectAllCallback into a C_FlowBoxUnselectAllCallback.
