Typedefed as TreeModel::Row.
Dereference a TreeModel::iterator to get the Row. Use operator[] or set_value() and get_value() to access the values in the columns of this row.
If the model contains a hierarchy of rows (such as Gtk::TreeStore), then you can access the child rows with children().
You can use get_iter() to get an iterator that points to the Row, e.g. for use in a parameter that takes a const TreeModel::iterator& or a const TreeModel::const_iterator&.
TreeNodeChildren & Gtk::TreeRow::children | ( | ) |
This returns an STL-like container API, for iterating over the rows.
See also Gtk::TreeModel::children() for the top-level children.
const TreeNodeConstChildren & Gtk::TreeConstRow::children | ( | ) | const |
This returns an STL-like container API, for iterating over the rows.
See also Gtk::TreeModel::children() for the top-level children.
Gets an iterator to this row.
TreeIter< TreeConstRow > Gtk::TreeConstRow::get_iter | ( | ) | const |
Gets a const_iterator to this row.
|
inline |
Use this to set and get the value of this column of this row.
This is a templated method, so the compiler will not allow you to provide an inappropriate type of data for the model column.
This is just a more convenient syntax that does the same thing as set_value() and get_value().
column | The model column. |
Gets an iterator to the parent row of this row.
TreeIter< TreeConstRow > Gtk::TreeConstRow::parent | ( | ) | const |
Gets a const_iterator to the parent row of this row.
void Gtk::TreeRow::set_value | ( | const TreeModelColumn< ColumnType > & | column, |
const ColumnType & | data | ||
) |
Sets the value of this column of this row.
This is a templated method, so the compiler will not allow you to provide an inappropriate type of data for the model column.
See also operator[]().
column | The model column. |
data | The new value to use for this column of this row. |
void Gtk::TreeRow::set_value | ( | int | column, |
const ColumnType & | data | ||
) |
Use set_value(const TreeModelColumn<>& column, const ColumnType& data) unless you do not know the column type at compile-time.
If the data is of an inappropriate C++ type then this might fail at runtime.
column | The number of the column whose value you want to change. |
data | The new value to use for this column of this row. |
