Equivalent to hildon_touch_selector_append_column(), but using a default text cell renderer. This is the most common use case of the widget.

Since 2.2

hildon_touch_selector_append_column ()

HildonTouchSelectorColumn* hildon_touch_selector_append_column
                                                        (HildonTouchSelector *selector,

                                                         GtkCellRenderer *cell_renderer,
                                                         ...);

This functions adds a new column to the widget, whose data will be obtained from the model. Only widgets added this way should used on the selection logic, the print function, the "changed" signal, etc. Internally, a GtkTreeView will be added to the widget, using model as the data source.

You can optionally pass a GtkCellRenderer in cell_renderer, together with a NULL-terminated list of pairs property/value, in the same way you would use gtk_tree_view_column_set_attributes(). This will pack cell_renderer at the start of the column, expanded by default. If you prefer not to add it this way, you can simply pass NULL to cell_renderer and use the GtkCellLayout interface on the returned HildonTouchSelectorColumn to set your renderers. Please note that the returned HildonTouchSelectorColumn is owned by selector, you shouldn't unref it after setting it up.

Initially, the returned HildonTouchSelectorColumn will have its "text-column" property unset. You should set it to a column in model with type G_TYPE_STRING. See hildon_touch_selector_column_set_text_column().

This method could change the current "hildon-ui-mode". HILDON_UI_MODE_NORMAL is only allowed with one column, so if the selector is in this mode, and a additional column is added, "hildon-ui-mode" will change to HILDON_UI_MODE_EDIT.

Determines whether selector is complex enough to actually require an extra selection step than only picking an item. This is normally TRUE if selector has multiple columns, multiple selection, or when it is a more complex widget, like HildonTouchSelectorEntry.

This information is useful for widgets containing a HildonTouchSelector, like HildonPickerDialog, that could need a "Done" button, in case that its internal HildonTouchSelector has multiple columns, for instance.

Gets the optimal size request of the touch selector. This function is mostly intended for dialog implementations that include a HildonTouchSelector and want to optimize the screen real state, for example, when you want a dialog to show as much of the selector, avoiding any extra empty space below the selector.

See HildonPickerDialog implementation for an example.

This function is oriented to be used in the size_request of a dialog or window, if you are not sure do not use it.

There is a precondition to this function: Since this function does not call the "size_request" method, it can only be used when you know that gtk_widget_size_request() has been called since the last time a resize was queued.

Since 2.2

The "has-multiple-selection" property

  "has-multiple-selection"   gboolean              : Read

Whether the widget has multiple selection (like multiple columns, multiselection mode, or multiple internal widgets) and therefore it may need a confirmation button, for instance.

Default value: FALSE

The "hildon-ui-mode" property

  "hildon-ui-mode"           HildonUIMode          : Read / Write

Specifies which UI mode to use in the internal treeviews. A setting of HILDON_UI_MODE_NORMAL will cause these tree view to disable selections and emit row-activated as soon as a row is pressed. You can use the method hildon_touch_selector_get_last_activated_row() to get it. When HILDON_UI_MODE_EDIT is set, selections can be made according to the setting of the mode on GtkTreeSelection.

Toggling this property will cause the tree view to select an appropriate selection mode if not already done.

Default value: HILDON_UI_MODE_EDIT

Since Hildon 2.2

The "initial-scroll" property

  "initial-scroll"           gboolean              : Read / Write / Construct

Default value: TRUE

The "changed" signal is emitted when the active item on any column is changed. This can be due to the user selecting a different item from the list, or due to a call to hildon_touch_selector_select_iter() on one of the columns.

Since 2.2

The "columns-changed" signal

void                user_function                      (HildonTouchSelector *selector,
