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().

Gtk::TreeView* | wrap (GtkTreeView* object, bool take_copy=false) |

A visible column in a Gtk::TreeView widget.

A selection object for Gtk::TreeView.

|
|
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. |

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

Creates a View column containing the CellRenderer, and appends it.
|
|
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, bool, Gdk::Pixbuf. Also, the default CellRenderer might not be setup exactly as needed. You might prefer to create the TreeViewColumn and or CellRenderer manually. You might provide a callback that converts the type into a string representation with TreeViewColumn::set_cell_data_func(). Otherwise, if the type is not supported, at run-time no text will appear in the column while the following warning will be generated repeatedly: GLib-GObject-WARNING**: unable to set property `text' of type `gchararray' from value of type `glibmm__CustomBoxed_t' TODO: Give a more specific warning and/or do more compile-time checks.
|
|
Appends column to the list of columns. If tree_view has "fixed_height" mode enbabled, then column must have its "sizing" property set to be GTK_TREE_VIEW_COLUMN_FIXED.
|
|
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 should use append_column() and connect a signal handler to the CellRenderer.

Fills the bounding rectangle in tree window coordinates for the cell at the row specified by path and the column specified by column . The returned rectangle is equivalent to the background_area passed to Gtk::CellRenderer::render(). These background areas tile to cover the entire tree window (except for the area used for header buttons). Contrast with the cell_area , returned by get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area.

Fills the bounding rectangle in tree window coordinates for the cell at the row specified by path and the column specified by column .

The returned rectangle is equivalent to the cell_area passed to Gtk::CellRenderer::render(). This function is only valid if #tree_view is realized.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Removes all View columns.

Removes column from tree_view .

This method resets the expander arrow to the default - the first visible column.

Activates the cell determined by path and column .

Moves the alignments of tree view to the position specified by column and path. The tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to it's current position. If the cell is currently visible on the screen, nothing is done. This function only works if the model is set, and path is a valid row on the model. If the model changes before the tree_view is realized, the centered path will be modified to reflect this change.
|
|
Moves the alignments of tree view to the position specified by column and path. row_align determines where the row is placed, and col_align determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center. This function only works if the model is set, and path is a valid row on the model. If the model changes before the tree view is realized, the centered path will be modified to reflect this change.

Scrolls the tree view such that the top-left corner of the visible area is tree_x , tree_y , where tree_x and tree_y are specified in tree window coordinates. The tree_view must be realized before this function is called. If it isn't, you probably want to be using scroll_to_cell(). If either tree_x or tree_y are -1, then that direction isn't scrolled.

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().

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. This function is often followed by Gtk::widget::grab_focus(tree_view) in order to give keyboard focus to the widget.

Sets the row that is highlighted for feedback.

If enable_search is set, then the user can type in text to search through the tree interactively.
|
|
Sets the column to draw the expander arrow at. It must be in the TreeView. See also reset_expander_column().
|
|
Sets the Gtk::Adjustment for the current horizontal aspect. See also unset_hadjustment().

Allow the column title buttons to be clicked.
|
|
Sets the the visibility state of the headers.
|
|
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. If model is

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 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.

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).

Sets column as the column where the interactive search code should search in. Additionally, turns on interactive searching. Note that column refers to a column of the model.
