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 insert(), and a FlowBoxChild widget will automatically be inserted between the box and the widget.
Also see ListBox.
Member Typedef Documentation
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.
- Returns
- A Gtk::Widget that represents item.
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
true
if the child should be visible,false
otherwise
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
-
box FlowBox containing the selected children child Each selected FlowBoxChild
typedef sigc::slot<int(FlowBoxChild*, FlowBoxChild*)> Gtk::FlowBox::SlotSort |
For instance: int on_sort(FlowBoxChild* child1, FlowBoxChild* child2)
Will be called for each child after a call to FlowBox::set_sort_func(), and will continue to be called each time a child changes (via FlowBoxChild::changed()) and when FlowBox::invalidate_sort() is called.
- Parameters
-
child1 The first child. child2 The second child.
- Returns
- < 0 if child1 should be before child2, 0 if they are equal, and > 0 otherwise

overridenoexcept |
Gtk::FlowBox::FlowBox | ( | ) |
Creates a FlowBox.
Member Function Documentation
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.
void Gtk::FlowBox::bind_model | ( | const Glib::RefPtr< Gio::ListModel > & | model, |
const SlotCreateWidget< Glib::Object >& | slot_create_widget | ||
) |
Binds a Gio::ListModel.
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.
- Parameters
-
model The Gio::ListModel to be bound. slot_create_widget A slot that creates widgets for items.
- See also
- bind_list_store()
bool Gtk::FlowBox::get_activate_on_single_click | ( | ) | const |
Returns whether children activate on single clicks.
- Returns
true
if children are activated on single click,false
otherwise.
FlowBoxChild* Gtk::FlowBox::get_child_at_index | ( | int | idx | ) |
Gets the nth child in the box.
- Parameters
-
idx The position of the child.
- Returns
- The child widget, which will always be a Gtk::FlowBoxChild or
nullptr
in case no child widget with the given index exists.
