## Detailed Description

The TreeView widget displays the model (Gtk::TreeModel) data and allows the user to interact with it.

The View can show all of the model's columns, or just some, and it can show them in various ways. You must provide the TreeModel in the constructor, or with set_model().

Add View columns with append_column(), append_column_editable(), insert_column(), or insert_column_editable().

You can manipulate the selection by obtaining the Gtk::TreeView::Selection from get_selection().

## Member Typedef Documentation

typedef TreeViewColumn Gtk::TreeView::Column

A visible column in a Gtk::TreeView widget.

typedef TreeSelection Gtk::TreeView::Selection

A selection object for Gtk::TreeView.

typedef TreeViewColumn::SlotCellData Gtk::TreeView::SlotCellData

typedef sigc::slot<bool, TreeView*, TreeViewColumn*, TreeViewColumn*, TreeViewColumn*> Gtk::TreeView::SlotColumnDrop

For instance, bool on_column_drop(TreeView*, tree_view, TreeViewColumn* column, TreeViewColumn* prev_column, TreeViewColumn* next_column)

This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to the function are: the tree_view, the view Column being dragged, and the two view Columns determining the drop spot. If either of the view Column arguments for the drop spot are 0, then they indicate an edge.

typedef sigc::slot<void, TreeView*, const TreeModel::Path&> Gtk::TreeView::SlotMapping

For example, void on_map_expanded_rows(TreeView* tree_view, const TreeModel::Path& path);.

typedef sigc::slot<bool, const Glib::RefPtr<TreeModel>&, const TreeModel::iterator&> Gtk::TreeView::SlotRowSeparator

For instance, void on_row_separator(const Gtk::TreeModel& model, const Gtk::TreeModel::iterator& iter);.

typedef sigc::slot<bool, const Glib::RefPtr<TreeModel>&, int, const Glib::ustring&, const TreeModel::iterator&> Gtk::TreeView::SlotSearchEqual

void on_search_equal(const Glib::RefPtr<TreeModel>& model, int column, const Glib::ustring& key, const TreeModel::iterator& iter)

typedef sigc::slot<void, Gtk::Widget* > Gtk::TreeView::SlotSearchPosition

void on_search_position(Gtk::Widget* search_dialog)

## Constructor & Destructor Documentation

virtual Gtk::TreeView::~TreeView | ( |  | ) |

virtual

Gtk::TreeView::TreeView | ( |  | ) |

Default constructor.

Gtk::TreeView::TreeView | ( | const Glib::RefPtr< TreeModel >& | model | ) |

explicit

Constructor that binds to a TreeModel.

## Member Function Documentation

int Gtk::TreeView::append_column | ( | TreeViewColumn& | column | ) |

Appends column to the list of columns.

If tree_view has "fixed_height" mode enabled, then column must have its "sizing" property set to be GTK_TREE_VIEW_COLUMN_FIXED.

Parameters

  column | The Gtk::TreeViewColumn to add.

Returns
  The number of columns in tree_view after appending.

template <class ColumnType >

int Gtk::TreeView::append_column | ( | const Glib::ustring & | title,
|  | const TreeModelColumn< ColumnType >& | model_column
| ) |  |

inline

Appends a View column with the appropriate CellRenderer for the Model column.

The CellRenderer can only be created automatically for some basic column types, such as Glib::ustring, int, double, bool, and Gdk::Pixbuf. If the type is not supported then the following warning will be shown: GLib-GObject-WARNING**: unable to set property `text' of type `gchararray' from value of type `glibmm__CustomBoxed_t'.

If the default formatting is not sufficient, or the numeric type is not supported, then you could use append_column_numeric(). Or you could create the TreeView::Column and/or CellRenderer manually and use TreeViewColumn::set_cell_data_func() to provide a callback that converts the model value into a string representation with .

Parameters

  title | The text to be used in the title header of this column.
  model_column | The column in the TreeModel that will be rendered by this View column.

Returns
  The number of columns in the View after appending.

int Gtk::TreeView::append_column | ( | const Glib::ustring & | title,
|  | CellRenderer& | cell
| ) |  |

Creates a View column containing the CellRenderer, and appends it.

template <class ColumnType >

int Gtk::TreeView::append_column_editable | ( | const Glib::ustring & | title,
|  | const TreeModelColumn< ColumnType >& | model_column
| ) |  |

inline

Appends a View column with the appropriate CellRenderer for the Model column.

The compiler will attempt to instantiate appropriate template code to automatically store user changes in the model. To intercept the user's change and implement non-default logic, or if the compiler can't instantiate appropriate code for your model type, you could use append_column() and connect a signal handler to the CellRenderer.

See also
  append_column_numeric_editable().

Parameters

  title | The text to be used in the title header of this column.
  model_column | The column in the TreeModel that will be rendered by this View column.

Returns
  The number of columns in the View after appending.

template <class ColumnType >

int Gtk::TreeView::append_column_numeric | ( | const Glib::ustring & | title,
|  | const TreeModelColumn< ColumnType >& | model_column,
|  | const Glib::ustring & | format
| ) |  |

inline

Like append_column(), but only for numeric types, which will be displayed in the specified format.

This convenience template uses TreeView::Column::set_cell_data_func(), so the numeric formatting will be deactivated if you specify your own cell_data callback by calling set_cell_data_func() again.

Parameters

  title | The text to be used in the title header of this column.
  model_column | The column in the TreeModel that will be rendered by this View column.
  format | A printf-style format, such as "%d", used to create a text representation of the number.

Returns
  The number of columns in the View after appending.

template <class ColumnType >

int Gtk::TreeView::append_column_numeric_editable | ( | const Glib::ustring & | title,
|  | const TreeModelColumn< ColumnType >& | model_column,
|  | const Glib::ustring & | format
| ) |  |

inline

Like append_column_editable(), but only for numeric types, which will be displayed in the specified format.

This convenience template uses TreeView::Column::set_cell_data_func(), so the numeric formatting will be deactivated if you specify your own cell_data callback by calling set_cell_data_func() again.

Note that the user's input will be interpreted as decimal (base 10), regardless of the format.

Parameters

  title | The text to be used in the title header of this column.
  model_column | The column in the TreeModel that will be rendered by this View column.
  format | A printf-style format, such as "%d", used to create a text representation of the number.

Parameters

  path | The path of the row to move to.

void Gtk::TreeView::set_column_drag_function | ( | const SlotColumnDrop& | slot | ) |

Sets a callback slot for determining where a column may be dropped when dragged.

This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to the function are: the tree_view, the view Column being dragged, and the two view Columns determining the drop spot. If either of the view Column arguments for the drop spot are 0, then they indicate an edge.

See unset_column_drag_function().

Parameters

| ) |  |

Sets the current keyboard focus to be at path, and selects it.

This is useful when you want to focus the user's attention on a particular row. Focus is given to the column specified. Additionally, if start_editing is `true`, then editing should be started in the specified cell. This function is often followed by Gtk::Widget::grab_focus( tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

Parameters

  path | A Gtk::TreePath.
  focus_column | A Gtk::TreeViewColumn.
  start_editing | `true` if the specified cell should start being edited.

void Gtk::TreeView::set_cursor | ( | const TreeModel::Path& | path,
|  | TreeViewColumn& | focus_column,
|  | CellRenderer& | focus_cell,
|  | bool | start_editing = `false`
| ) |  |

Sets the current keyboard focus to be at path, and selects it.

This is useful when you want to focus the user's attention on a particular row. If focus_column is not `nullptr`, then focus is given to the column specified by it. If focus_column and focus_cell are not `nullptr`, and focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by focus_cell. Additionally, if focus_column is specified, and start_editing is `true`, then editing should be started in the specified cell. This function is often followed by gtk_widget_grab_focus ( tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

If path is invalid for model, the current cursor (if any) will be unset and the function will return without failing.

Since gtkmm 2.2:

Parameters

  path | A Gtk::TreePath.
  focus_column | A Gtk::TreeViewColumn, or `nullptr`.

Sets whether to draw lines interconnecting the expanders in tree_view.

This does not have any visible effects for lists.

Since gtkmm 2.10:

Parameters

  enable | `true` to enable tree line drawing, `false` otherwise.

void Gtk::TreeView::set_expander_column | ( | TreeViewColumn& | column | ) |

Sets the column to draw the expander arrow at.

It must be in the TreeView. See also reset_expander_column().

Parameters

  column | The column to draw the expander arrow at.

void Gtk::TreeView::set_fixed_height_mode | ( | bool | enable = `true` | ) |

Enables or disables the fixed height mode of tree_view.

Fixed height mode speeds up Gtk::TreeView by assuming that all rows have the same height. Only enable this option if all rows are the same height and all columns are of type Gtk::TREE_VIEW_COLUMN_FIXED.

Since gtkmm 2.6:

Parameters

  enable | `true` to enable fixed height mode.

void Gtk::TreeView::set_grid_lines | ( | TreeViewGridLines | grid_lines | ) |

Sets which grid lines to draw in tree_view.

Since gtkmm 2.10:

Parameters

  grid_lines | A Gtk::TreeViewGridLines value indicating which grid lines to enable.

void Gtk::TreeView::set_hadjustment | ( | Adjustment& | adjustment | ) |

Sets the Gtk::Adjustment for the current horizontal aspect.

See also unset_hadjustment().

Parameters

  adjustment | The Gtk::Adjustment to set.

void Gtk::TreeView::set_headers_clickable | ( | bool | setting = `true` | ) |

Allow the column title buttons to be clicked.

Parameters

  setting | `true` if the columns are clickable.

void Gtk::TreeView::set_headers_visible | ( | bool | headers_visible = `true` | ) |

Sets the visibility state of the headers.

Parameters

  headers_visible | `true` if the headers are visible.

void Gtk::TreeView::set_hover_expand | ( | bool | expand = `true` | ) |

Enables of disables the hover expansion mode of tree_view.

Hover expansion makes rows expand or collapse if the pointer moves over them.

Since gtkmm 2.6:

Parameters

  expand | `true` to enable hover selection mode.

void Gtk::TreeView::set_hover_selection | ( | bool | hover = `true` | ) |

Enables of disables the hover selection mode of tree_view.

Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes Gtk::SELECTION_SINGLE and Gtk::SELECTION_BROWSE.

Since gtkmm 2.6:

Parameters

  hover | `true` to enable hover selection mode.

void Gtk::TreeView::set_level_indentation | ( | int | indentation | ) |

Sets the amount of extra indentation for child levels to use in tree_view in addition to the default indentation.

The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.

Since gtkmm 2.12:

Parameters

  indentation | The amount, in pixels, of extra indentation in tree_view.

void Gtk::TreeView::set_model | ( | const Glib::RefPtr< TreeModel >& | model | ) |

Sets the model for a Gtk::TreeView.

If the tree_view already has a model set, it will remove it before setting the new model. Use unset_model() to unset the old model.

Parameters

  model | The model.

void Gtk::TreeView::set_reorderable | ( | bool | reorderable = `true` | ) |

This function is a convenience function to allow you to reorder models that support the Gtk::DragSourceIface and the Gtk::DragDestIface.

Both Gtk::TreeStore and Gtk::ListStore support these. If reorderable is `true`, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's row_inserted and row_deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

This function does not give you any degree of control over the order – any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.

Parameters

  reorderable | `true`, if the tree can be reordered.

void Gtk::TreeView::set_row_separator_func | ( | const SlotRowSeparator& | slot | ) |

void Gtk::TreeView::set_rubber_banding | ( | bool | enable = `true` | ) |

Enables or disables rubber banding in tree_view.

If the selection mode is Gtk::SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

Since gtkmm 2.10:

Parameters

  enable | `true` to enable rubber banding.

void Gtk::TreeView::set_rules_hint | ( | bool | setting = `true` | ) |

This function tells GTK+ that the user interface for your application requires users to read across tree rows and associate cells with one another.

By default, GTK+ will then render the tree with alternating row colors. Do not use it just because you prefer the appearance of the ruled tree; that's a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors useful from a functional standpoint (since it has lots of columns, generally).

Parameters

  setting | `true` if the tree requires reading across rows.

void Gtk::TreeView::set_search_column | ( | const TreeModelColumnBase& | column | ) |

Sets column as the column where the interactive search code should search in for the current model.

If the search column is set, users can use the "start-interactive-search" key binding to bring up search popup. The enable-search property controls whether simply typing text will also start an interactive search.

Note that column refers to a column of the current model. The search column is reset to -1 when the model is changed.

Parameters

  column | The column of the model to search in, or -1 to disable searching.

void Gtk::TreeView::set_search_column | ( | int | column | ) |

Sets column as the column where the interactive search code should search in for the current model.

If the search column is set, users can use the "start-interactive-search" key binding to bring up search popup. The enable-search property controls whether simply typing text will also start an interactive search.

Note that column refers to a column of the current model. The search column is reset to -1 when the model is changed.

Parameters

  column | The column of the model to search in, or -1 to disable searching.

void Gtk::TreeView::set_search_entry | ( | Entry& | entry | ) |

Sets the entry which the interactive search code will use for this tree_view.

This is useful when you want to provide a search entry in our interface at all time at a fixed position. Passing `nullptr` for entry will make the interactive search code use the built-in popup entry again.

Since gtkmm 2.10:

Parameters

  entry | The entry the interactive search code of tree_view should use or `nullptr`.

void Gtk::TreeView::set_search_equal_func | ( | const SlotSearchEqual& | slot | ) |

Sets the compare function for the interactive search capabilities.

Parameters

  slot | The compare function to use during the search

void Gtk::TreeView::set_search_position_func | ( | const SlotSearchPosition& | slot | ) |

void Gtk::TreeView::set_show_expanders | ( | bool | enabled = `true` | ) |

Sets whether to draw and enable expanders and indent child rows in tree_view.

When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using set_level_indentation(). This does not have any visible effects for lists.

Since gtkmm 2.12:

Parameters

  enabled | `true` to enable expander drawing, `false` otherwise.

void Gtk::TreeView::set_tooltip_cell | ( | const Glib::RefPtr< Tooltip >& | tooltip,
|  | const TreeModel::Path* | path,
|  | TreeViewColumn* | column,
|  | CellRenderer* | cell
| ) |  |

Sets the tip area of tooltip to the area path, column and cell have in common.

For example if path is `nullptr` and column is set, the tip area will be set to the full area covered by column. See also Gtk::Tooltip::set_tip_area().

Note that if path is not specified and cell is set and part of a column containing the expander, the tooltip might not show and hide at the correct position. In such cases path must be set to the current node under the mouse cursor for this function to operate correctly.

See also set_tooltip_column() for a simpler alternative.

Since gtkmm 2.12:

Parameters

  tooltip | A Gtk::Tooltip.
  path | A Gtk::TreePath or `nullptr`.
  column | A Gtk::TreeViewColumn or `nullptr`.
  cell | A Gtk::CellRenderer or `nullptr`.

void Gtk::TreeView::set_tooltip_column | ( | int | column | ) |

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have Gtk::TreeView handle these automatically for you.

column should be set to the column in tree_view's model containing the tooltip texts, or -1 to disable this feature.

When enabled, Gtk::Widget::signal_has_tooltip() will be set to `true` and tree_view will connect a Gtk::Widget::signal_query_tooltip() signal handler.

Note that the signal handler sets the text with Gtk::Tooltip::set_markup(), so&, <, etc have to be escaped in the text.

Since gtkmm 2.12:

Parameters

  column | An integer, which is a valid column number for tree_view's model.

void Gtk::TreeView::set_tooltip_row | ( | const Glib::RefPtr< Tooltip >& | tooltip,
|  | const TreePath& | path
| ) |  |

Sets the tip area of tooltip to be the area covered by the row at path.

See also set_tooltip_column() for a simpler alternative.

See also Tooltip::set_tip_area().

Parameters

  path | A Gtk::TreePath.

void Gtk::TreeView::set_vadjustment | ( | Adjustment& | adjustment | ) |

Sets the Gtk::Adjustment for the current vertical aspect.

See also unset_vadjustment().
