Description

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.

GtkFlowBox uses a single CSS node with name flowbox. GtkFlowBoxChild uses a single CSS node with name flowboxchild. For rubberband selection, a subnode with name rubberband is used.

Type class for types which can be safely cast to FlowBox, for instance with toFlowBox.

Instance details

Defined in GI.Gtk.Objects.FlowBox

toFlowBox :: (MonadIO m, IsFlowBox o) => o -> m FlowBox Source #

Cast to FlowBox, for types for which this is known to be safe. For general casts, use castTo.

noFlowBox :: Maybe FlowBox Source #

A convenience alias for Nothing :: Maybe FlowBox.

Methods

bindModel

flowBoxBindModel Source #

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.
