Struct gtk4::StringList

#[repr(transparent)]
pub struct StringList { /* private fields */ }

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

The objects in the model have a “string” property.

StringList is well-suited for any place where you would typically use a char*[], but need a list model.

GtkStringList as GtkBuildable

The StringList implementation of the Buildable interface supports adding items directly using the 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 StringList

<object class="GtkStringList">
  <items>
    <item translatable="yes">Factory</item>
    <item translatable="yes">Home</item>
    <item translatable="yes">Subway</item>
  </items>
</object>

Implementations

impl StringList

pub fn new(strings: &[&str]) -> StringList

Creates a new StringList with the given @strings.

strings

The strings to put in the model

Returns

a new StringList

pub fn append(&self, string: &str)

Appends @string to @self.

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

string

the string to insert

pub fn string(&self, position: u32) -> Option<GString>

Gets the string that is at @position in @self.

If @self does not contain @position items, None is returned.

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

position

the position to get the string for

Returns

the string at the given position

pub fn remove(&self, position: u32)

Removes the string at @position from @self.

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

position

the position of the string that is to be removed

pub fn splice(&self, position: u32, n_removals: u32, additions: &[&str])

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 ::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).

position

the position at which to make the change

n_removals

the number of strings to remove

additions

The strings to add

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StringList

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for StringList

fn static_type() -> Type

Returns the type identifier of Self.
