Sets our main struct and passes it to the parent class.
Creates a GtkFlowBox.
The ::activate-cursor-child signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user activates the @box.
The ::child-activated signal is emitted when a child has been activated by the user.
The ::move-cursor signal is a [keybinding signal]GtkBindingSignal which gets emitted when the user initiates a cursor movement.
The ::select-all signal is a [keybinding signal]GtkBindingSignal which gets emitted to select all children of the box, if the selection mode permits it.
The ::selected-children-changed signal is emitted when the set of selected children changes.
The ::toggle-cursor-child signal is a [keybinding signal]GtkBindingSignal which toggles the selection of the child that has the focus.
The ::unselect-all signal is a [keybinding signal]GtkBindingSignal which gets emitted to unselect all children of the box, if the selection mode permits it.
Binds @model to @box.
Returns whether children activate on single clicks.
Gets the nth child in the @box.
Gets the child in the (@x, @y) position.
Gets the horizontal spacing.
Get the main Gtk struct
Returns whether the box is homogeneous (all children are the same size). See gtk_box_set_homogeneous().
Gets the maximum number of children per line.
Gets the minimum number of children per line.
Gets the vertical spacing.
Creates a list of all selected children.
Gets the selection mode of @box.
the main Gtk struct as a void*
Inserts the @widget into @box at @position.
Updates the filtering for all children.
Updates the sorting for all children.
Select all children of @box, if the selection mode allows it.
Selects a single child of @box, if the selection mode allows it.
Calls a function for each selected child.
If @single is %TRUE, children will be activated when you click on them, otherwise you need to double-click.
Sets the horizontal space to add between children. See the #GtkFlowBox:column-spacing property.
By setting a filter function on the @box one can decide dynamically which of the children to show. For instance, to implement a search function that only shows the children matching the search terms.
Hooks up an adjustment to focus handling in @box. The adjustment is also used for autoscrolling during rubberband selection. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment, and gtk_flow_box_set_vadjustment()for setting the vertical adjustment.
Sets the #GtkFlowBox:homogeneous property of @box, controlling whether or not all children of @box are given equal space in the box.
Sets the maximum number of children to request and allocate space for in @box’s orientation.
Sets the minimum number of children to line up in @box’s orientation before flowing.
Sets the vertical space to add between children. See the #GtkFlowBox:row-spacing property.
Sets how selection works in @box. See #GtkSelectionMode for details.
By setting a sort function on the @box, one can dynamically reorder the children of the box, based on the contents of the children.
Hooks up an adjustment to focus handling in @box. The adjustment is also used for autoscrolling during rubberband selection. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment, and gtk_flow_box_set_hadjustment()for setting the horizontal adjustment.
Unselect all children of @box, if the selection mode allows it.
Unselects a single child of @box, if the selection mode allows it.

Removes all widgets from the container
Adds @widget to @container. Typically used for simple containers such as #GtkWindow, #GtkFrame, or #GtkButton; for more complicated layout containers such as #GtkBox or #GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.
Gets the value of a child property for @child and @container.
Gets the values of one or more child properties for @child and @container.
Emits a #GtkWidget::child-notify signal for the [child property][child-properties] @child_property on the child.
Emits a #GtkWidget::child-notify signal for the [child property][child-properties] specified by @pspec on the child.
Sets a child property for @child and @container.
Sets one or more child properties for @child and @container.
Returns the type of the children supported by the container.
Invokes @callback on each direct child of @container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.
Invokes @callback on each non-internal child of @container. See gtk_container_forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.
Retrieves the border width of the container. See gtk_container_set_border_width().
Returns the container’s non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child.
Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores %NULL in @focusable_widgets and returns %FALSE.
Returns the current focus child widget inside @container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus().
Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().
Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including @child.
Returns the resize mode for the container. See gtk_container_set_resize_mode ().
When a container receives a call to the draw function, it must send synthetic #GtkWidget::draw calls to all children that don’t have their own #GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its #GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the @cr the container received.
Removes @widget from @container. @widget must be inside @container. Note that @container will own a reference to @widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use @widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use @widget again it’s usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.
Sets the border width of the container.
Sets a focus chain, overriding the one computed automatically by GTK+.
Sets, or unsets if @child is %NULL, the focused child of @container.
Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment.

See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment.
Sets the @reallocate_redraws flag of the container to the given value.
Sets the resize mode for the container.
Removes a focus chain explicitly set with gtk_container_set_focus_chain().

Retrieves the orientation of the @orientable.
Sets the orientation of the @orientable.
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 #GtkScrolledWindow to enable that.
The children of a GtkFlowBox can be dynamically sorted and filtered.
Although a GtkFlowBox must have only #GtkFlowBoxChild children, you can add any kind of widget to it via gtk_container_add(), and a GtkFlowBoxChild widget will automatically be inserted between the box and the widget.
Also see #GtkListBox.
GtkFlowBox was added in GTK+ 3.12.
CSS nodes
