Detailed Description
A container that allows reflowing its children.
A FlowBox 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 children of a FlowBox can be dynamically sorted and filtered.
Although a FlowBox must have only FlowBoxChild children, you can add any kind of widget to it via Container::add(), and a FlowBoxChild widget will automatically be inserted between the box and the widget.
Also see ListBox.
Member Typedef Documentation
◆ SlotCreateWidget
template <typename T_item >
| using Gtk::FlowBox::SlotCreateWidget = sigc::slot<Gtk::Widget*, const Glib::RefPtr<T_item>&> |
For instance: Gtk::Widget* on_create_widget(const Glib::RefPtr<T_item>& item);.
Called for flow boxes that are bound to a Gio::ListModel with bind_model() or bind_list_store() for each item that gets added to the model.
- Template Parameters
-
T_item Base class of the items in the Gio::ListModel. All items must be of type T_item or a type derived from T_item. T_item must be Glib::Object or a type derived from Glib::Object.
- Parameters
-
item The item from the model for which to create a widget. @eturn A Gtk::Widget that represents item.
◆ SlotFilter
| typedef sigc::slot<bool, FlowBoxChild*> Gtk::FlowBox::SlotFilter |
For instance: bool on_filter(FlowBoxChild* child);.
Will be called for each child after a call to FlowBox::set_filter_func(), and it will continue to be called each time a child changes (via FlowBoxChild::changed()) or when FlowBox::invalidate_filter() is called.
- Parameters
-
child A FlowBoxChild that may be filtered
- Returns
trueif the child should be visible,falseotherwise
◆ SlotSelectedForeach
| typedef sigc::slot<void, FlowBox*, FlowBoxChild*> Gtk::FlowBox::SlotSelectedForeach |
For instance: void foreach_child(FlowBox* box, FlowBoxChild* child);.
A function used by FlowBox::selected_foreach(). It will be called on every selected child of the box.
- Parameters
-

◆ bind_list_store()
template <typename T_item , typename T_slot >
| void Gtk::FlowBox::bind_list_store | ( | const Glib::RefPtr< Gio::ListStore< T_item > > & | store, |
| T_slot && | slot_create_widget | ||
| ) |
Binds a Gio::ListStore<>.
If this FlowBox was already bound to a Gio::ListModel, that previous binding is destroyed. (Gio::ListStore is a Gio::ListModel.)
The contents of the FlowBox are cleared and then filled with widgets that represent items from store. The FlowBox is updated whenever store changes. If store is an empty Glib::RefPtr, the FlowBox is left empty.
It is undefined to add or remove widgets directly (for example, with insert() or Gtk::Container::add()) while the FlowBox is bound to a model.
Note that using a model is incompatible with the filtering and sorting functionality in FlowBox. When using a model, filtering and sorting should be implemented by the model.
- Template Parameters
-
T_item Base class of the items in the Gio::ListStore. All items must be of type T_item or a type derived from T_item. T_item must be Glib::Object or a type derived from Glib::Object. T_slot SlotCreateWidget<T_item> or a type that can be converted to SlotCreateWidget<T_item>.
- Parameters
-
store The Gio::ListStore<> to be bound. slot_create_widget A slot that creates widgets for items.

If this FlowBox was already bound to a model, that previous binding is destroyed.
The contents of the FlowBox are cleared and then filled with widgets that represent items from model. The FlowBox is updated whenever model changes. If model is an empty Glib::RefPtr, the FlowBox is left empty.
It is undefined to add or remove widgets directly (for example, with insert() or Gtk::Container::add()) while the FlowBox is bound to a model.
Note that using a model is incompatible with the filtering and sorting functionality in FlowBox. When using a model, filtering and sorting should be implemented by the model.
