Constructor & Destructor Documentation
|
noexcept |
|
overridenoexcept |
|
protected |
When using this constructor, you must use set_column_types() immediately afterwards.
This can be useful when deriving from this class, with a fixed TreeModelColumnRecord that is a member of the class. There is no create() method that corresponds to this constructor, because this constructor should only be used by derived classes.

Member Function Documentation
iterator Gtk::TreeStore::append | ( | ) |
Creates a new row at the end of the top-level.
The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and prepend().
- Returns
- An iterator to the new row.
iterator Gtk::TreeStore::append | ( | const TreeNodeChildren& | node | ) |
Creates a new row at the end of the row's children.
The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and prepend().
- Parameters
-
node The list of the parent row's children, as returned by Gtk::TreeModel::iterator::children().
- Returns
- An iterator to the new row.
void Gtk::TreeStore::clear | ( | ) |
Removes all rows from tree_store.
|
static |
Removes the given row from the list store.
- Parameters
-
iter The iterator to the row to be removed.
- Returns
- An iterator to the next row, or end() if there is none.

GtkTreeStore* Gtk::TreeStore::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
Creates a new row before the position.
If iter is end() then a new row will be appended to the list. The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also prepend() and append().
- Parameters
-
iter An iterator to the row before which the new row will be inserted.
- Returns
- An iterator to the new row.
Creates a new row after the position.
If iter is end() then a new row will be prepended to the list. The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also prepend() and append().
- Parameters
-
iter An iterator to the row after which the new row will be inserted.
- Returns
- An iterator to the new row.
bool Gtk::TreeStore::is_ancestor | ( | const const_iterator& | iter, |
const const_iterator& | descendant | ||
) | const |
Returns true
if iter is an ancestor of descendant.
That is, iter is the parent (or grandparent or great-grandparent) of descendant.
- Parameters
-
iter A valid Gtk::TreeIter. descendant A valid Gtk::TreeIter.
- Returns
true
, if iter is an ancestor of descendant.
int Gtk::TreeStore::iter_depth | ( | const const_iterator& | iter | ) | const |
Returns the depth of iter.
This will be 0 for anything on the root level, 1 for anything down a level, etc.
- Parameters
-
iter A valid Gtk::TreeIter.
- Returns
- The depth of iter.
bool Gtk::TreeStore::iter_is_valid | ( | const const_iterator& | iter | ) | const |
WARNING: This function is slow.
Only use it for debugging and/or testing purposes.
Checks if the given iter is a valid iter for this Gtk::TreeStore.
- Parameters
-
iter A Gtk::TreeIter.
- Returns
true
if the iter is valid,false
if the iter is invalid.
Swaps a and b in the same level of tree_store.
Note that this function only works with unsorted stores.
- Parameters
-
a A Gtk::TreeIter. b Another Gtk::TreeIter.
Moves source to the position at destination.
source and destination should be at the same level. Note that this function only works with unsorted stores.
- Parameters
-
source The row that should be moved. destination The position to move to.
iterator Gtk::TreeStore::prepend | ( | ) |
Creates a new row at the start of the top-level.
The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and append().
- Returns
- An iterator to the new row.
iterator Gtk::TreeStore::prepend | ( | const TreeNodeChildren& | node | ) |
Creates a new row at the start of the row's children.
The row will be empty - to fill in values, you need to dereference the returned iterator and use Row::operator[] or Row::set_value(). See also insert() and append().
- Parameters
-
node The list of the parent row's children, as returned by Gtk::TreeModel::iterator::children().
- Returns
- An iterator to the new row.
void Gtk::TreeStore::reorder | ( | const TreeNodeChildren& | node, |
const std::vector< int > & | new_order | ||
) |
Reorders the children of node to follow the order indicated by new_order.
Note that this function only works with unsorted stores.
void Gtk::TreeStore::set_column_types | ( | const TreeModelColumnRecord& | columns | ) |
|
overrideprotectedvirtual |
Override and implement this in a derived TreeModel class, so that Row::operator() and Row::set_value() work.
Your implementation of set_value_impl() should call row_changed() after changing the value.
Reimplemented from Gtk::TreeModel.
