Detailed Description

A row in a Gtk::TreeListModel.

Gtk::TreeListRow is the object used by Gtk::TreeListModel to represent items. It allows navigating the model as a tree and modify the state of rows.

Gtk::TreeListRow instances are created by a Gtk::TreeListModel only when the Gtk::TreeListModel::property_passthrough() property is not set.

There are various support objects that can make use of Gtk::TreeListRow objects, such as the Gtk::TreeExpander widget that allows displaying an icon to expand or collapse a row or Gtk::TreeListRowSorter that makes it possible to sort trees properly.

Member Function Documentation

◆ get_child_row() [1/2]

Glib::RefPtr< TreeListRow > Gtk::TreeListRow::get_child_row ( guint position )

If self is not expanded or position is greater than the number of children, nullptr is returned.

Parameters

position Position of the child to get.

Returns: The child in position.

◆ get_child_row() [2/2]

Glib::RefPtr< const TreeListRow > Gtk::TreeListRow::get_child_row ( guint position ) const

If self is not expanded or position is greater than the number of children, nullptr is returned.

Parameters

position Position of the child to get.

Returns: The child in position.

◆ get_children() [1/2]

Glib::RefPtr< Gio::ListModel > Gtk::TreeListRow::get_children ( )

If the row is expanded, gets the model holding the children of self.

This model is the model created by the [callb.nosp@m.ack@.nosp@m.Gtk.T.nosp@m.reeL.nosp@m.istMo.nosp@m.delC.nosp@m.reate.nosp@m.Mode.nosp@m.lFunc] and contains the original items, no matter what value Gtk::TreeListModel::property_passthrough() is set to.

Returns: The model containing the children.

◆ get_children() [2/2]

Glib::RefPtr< const Gio::ListModel > Gtk::TreeListRow::get_children ( ) const

If the row is expanded, gets the model holding the children of self.

This model is the model created by the [callb.nosp@m.ack@.nosp@m.Gtk.T.nosp@m.reeL.nosp@m.istMo.nosp@m.delC.nosp@m.reate.nosp@m.Mode.nosp@m.lFunc] and contains the original items, no matter what value Gtk::TreeListModel::property_passthrough() is set to.

Returns: The model containing the children.

◆ get_depth()

guint Gtk::TreeListRow::get_depth ( ) const

Gets the depth of this row.

Rows that correspond to items in the root model have a depth of zero, rows corresponding to items of models of direct children of the root model have a depth of 1 and so on.

The depth of a row never changes until the row is destroyed.

Returns: The depth of this row.

◆ get_expanded()

bool Gtk::TreeListRow::get_expanded ( ) const

Gets if a row is currently expanded.

Returns: true if the row is expanded.

◆ get_item() [1/2]

Glib::RefPtr< Glib::ObjectBase > Gtk::TreeListRow::get_item ( )

Gets the item corresponding to this row,.

The value returned by this function never changes until the row is destroyed.

Returns: The item of this row or nullptr when the row was destroyed.

◆ get_item() [2/2]

Glib::RefPtr< const Glib::ObjectBase > Gtk::TreeListRow::get_item ( ) const

Gets the item corresponding to this row,.

The value returned by this function never changes until the row is destroyed.

Returns: The item of this row or nullptr when the row was destroyed.

◆ get_parent() [1/2]

Glib::RefPtr< TreeListRow > Gtk::TreeListRow::get_parent ( )

Gets the row representing the parent for self.

That is the row that would need to be collapsed to make this row disappear.

If self is a row corresponding to the root model, nullptr is returned.

The value returned by this function never changes until the row is destroyed.

Returns: The parent of self.

◆ get_parent() [2/2]

Glib::RefPtr< const TreeListRow > Gtk::TreeListRow::get_parent ( ) const

Gets the row representing the parent for self.

That is the row that would need to be collapsed to make this row disappear.

If self is a row corresponding to the root model, nullptr is returned.

The value returned by this function never changes until the row is destroyed.

Returns: The parent of self.

◆ get_position()

guint Gtk::TreeListRow::get_position ( ) const

Returns the position in the Gtk::TreeListModel that self occupies at the moment.

Returns: The position in the model.

◆ get_type()

static GType Gtk::TreeListRow::get_type ( )

static

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

◆ gobj() [1/2]

GtkTreeListRow * Gtk::TreeListRow::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkTreeListRow * Gtk::TreeListRow::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkTreeListRow * Gtk::TreeListRow::gobj_copy ( )

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

◆ is_expandable()

bool Gtk::TreeListRow::is_expandable ( ) const

Checks if a row can be expanded.

This does not mean that the row is actually expanded, this can be checked with get_expanded().

If a row is expandable never changes until the row is destroyed.

Returns: true if the row is expandable.

◆ operator=()

TreeListRow & Gtk::TreeListRow::operator= ( TreeListRow && src )

noexcept

◆ property_children()

Glib::PropertyProxy_ReadOnly< Glib::RefPtr< Gio::ListModel > > Gtk::TreeListRow::property_children ( ) const

The model holding the row's children.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_depth()

Glib::PropertyProxy_ReadOnly< guint > Gtk::TreeListRow::property_depth ( ) const

The depth in the tree of this row.

Default value: 0

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_expandable()

Glib::PropertyProxy_ReadOnly< bool > Gtk::TreeListRow::property_expandable ( ) const

If this row can ever be expanded.

Default value: false

Default value: false

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_expanded() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::TreeListRow::property_expanded ( ) const

If this row is currently expanded.

Default value: false

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_item()

Glib::PropertyProxy_ReadOnly< Glib::RefPtr< Glib::ObjectBase > > Gtk::TreeListRow::property_item ( ) const

The item held in this row.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ set_expanded()

void Gtk::TreeListRow::set_expanded ( bool expanded = true )

Expands or collapses a row.

If a row is expanded, the model of calling the [callb.nosp@m.ack@.nosp@m.Gtk.T.nosp@m.reeL.nosp@m.istMo.nosp@m.delC.nosp@m.reate.nosp@m.Mode.nosp@m.lFunc] for the row's item will be inserted after this row. If a row is collapsed, those items will be removed from the model.

If the row is not expandable, this function does nothing.

Parameters

expanded true if the row should be expanded.
