Gtk::TreeView Class Reference
[Widgets, Container Widgets, TreeView Classes]

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().

Constructor that binds to a TreeModel.
Member Function Documentation
Glib::RefPtr<Gtk::TreeModel> Gtk::TreeView::_get_base_model | ( | ) |
Get the treeview's model, but actually get the child model if it's a TreeModelFilter.
int Gtk::TreeView::append_column | ( | const Glib::ustring & | title, | |
CellRenderer& | cell | |||
) |
Creates a View column containing the CellRenderer, and appends it.
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.
References append_column(), and Gtk::manage().
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.

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.

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.

) | [inline] |
Inserts 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 should use append_column() and connect a signal handler to the CellRenderer.
- 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. position The position at which the CellRenderer should be inserted.
- Returns:
- The number of columns in the View after inserting.

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.
- 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 <emphasis>not</emphasis> 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 <emphasis>semantic</emphasis> 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 | ( | 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_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_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 0
for entry will make the interactive search code use the built-in popup entry again.
- Parameters:
-
entry The entry the interactive search code of tree_view should use or 0
.
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.
- 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 0
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.
- Parameters:
-
tooltip A Gtk::Tooltip. path A Gtk::TreePath or 0
.column A Gtk::TreeViewColumn or 0
.cell A Gtk::CellRenderer or 0
.
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::has-tooltip will be set to true
and tree_view will connect a Gtk::Widget::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.
- 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().
- Parameters:
-
adjustment The Gtk::Adjustment to set.
