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.
|
|
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 . If path points to a path not currently displayed, the y and height fields of the rectangle will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the cell_area passed to Gtk::CellRenderer::render(). This function is only valid if #tree_view is realized.

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.

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 reorderering 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.
