Detailed Description

A list model for strings.

Gtk::StringList is a list model that wraps an array of strings.

The objects in the model have a "string" property.

GtkStringList is well-suited for any place where you would typically use a vector or array of Glib::ustring, but need a list model.

Gtk::StringList as Gtk::Buildable
The Gtk::StringList implementation of the Gtk::Buildable interface supports adding items directly using the <items> element and specifying elements for each item. Each element supports the regular translation attributes “translatable”, “context” and “comments”.
Here is a UI definition fragment specifying a Gtk::StringList
<object class="GtkStringList">
<items>
<item translatable="yes">Factory</item>
<item translatable="yes">Home</item>
<item translatable="yes">Subway</item>
</items>
</object>

Member Function Documentation

◆ append()

void Gtk::StringList::append ( const Glib::ustring &  string)

Appends string to self.

The string will be copied. See take() for a way to avoid that.

Parameters
stringThe string to insert.

◆ create()

static Glib::RefPtr<StringList> Gtk::StringList::create ( const std::vector< Glib::ustring > &  strings)
static

◆ get_string()

Glib::ustring Gtk::StringList::get_string ( guint  position) const

Gets the string that is at position in self.

If self does not contain position items, nullptr is returned.

This function returns the const char *. To get the object wrapping it, use Glib::list_model_get_item().

Parameters
positionThe position to get the string for.
Returns
The string at the given position.

◆ get_type()

static GType Gtk::StringList::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkStringList* Gtk::StringList::gobj ( )
inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkStringList* Gtk::StringList::gobj ( ) const
inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkStringList* Gtk::StringList::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ operator=()

StringList& Gtk::StringList::operator= ( StringList &&  src)
noexcept

◆ remove()

void Gtk::StringList::remove ( guint  position)

Removes the string at position from self.

position must be smaller than the current length of the list.

Parameters
positionThe position of the string that is to be removed.

◆ splice()

void Gtk::StringList::splice ( guint  position,
guint  n_removals,
const std::vector< Glib::ustring > &  additions 
)

Changes self by removing n_removals strings and adding additions to it.

This function is more efficient than append() and remove(), because it only emits the signal_items_changed() signal once for the change.

This function copies the strings in additions.

The parameters position and n_removals must be correct (ie: position + n_removals must be less than or equal to the length of the list at the time this function is called).

Parameters
positionThe position at which to make the change.
n_removalsThe number of strings to remove.
additionsThe strings to add.

◆ wrap()

Glib::RefPtr< Gtk::StringList > wrap ( GtkStringList *  object,
bool  take_copy = false 
)
related

A Glib::wrap() method for this object.

Parameters
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns
A C++ instance that wraps this C instance.
