void Gtk::Toolbar::set_drop_highlight_item | ( | ToolItem& | tool_item,
|  | int | index |
| ) |  |  |

Highlights toolbar to give an idea of what it would look like if item was added to toolbar at the position indicated by index.

If item is `0`, highlighting is turned off. In that case index is ignored.

The tool_item passed to this function must not be part of any widget hierarchy. When an item is set as drop highlight item it can not added to any widget hierarchy or used as highlight item for another toolbar.

Since gtkmm 2.4:

Parameters:

  | tool_item | A Gtk::ToolItem, or `0` to turn of highlighting.
  | index | A position on toolbar.

void Gtk::Toolbar::set_icon_size | ( | IconSize | icon_size | ) |

This function sets the size of stock icons in the toolbar.

You can call it both before you add the icons and after they've been added. The size you set will override user preferences for the default icon size.

This should only be used for special-purpose toolbars, normal application toolbars should respect the user preferences for the size of icons.

Since gtkmm 2.12:

Parameters:

  | icon_size | The Gtk::IconSize that stock icons in the toolbar shall have.

void Gtk::Toolbar::set_show_arrow | ( | bool | show_arrow = `true` | ) |

Sets whether to show an overflow menu when toolbar doesn't have room for all items on it.

If `true`, items that there are not room are available through an overflow menu.

Since gtkmm 2.4:

Parameters:

  | show_arrow | Whether to show an overflow menu.

void Gtk::Toolbar::set_toolbar_style | ( | ToolbarStyle | style | ) |

Alters the view of toolbar to display either icons only, text only, or both.

Parameters:

  | style | The new style for toolbar.

Glib::SignalProxy1< void,Orientation > Gtk::Toolbar::signal_orientation_changed | ( |  | ) |

Emitted when the orientation of the toolbar changes.

Parameters:

  | orientation | The new Orientation of the toolbar.

Prototype:
  `void on_my_orientation_changed(Orientation orientation)`

Glib::SignalProxy3< bool,int,int,int > Gtk::Toolbar::signal_popup_context_menu | ( |  | ) |

Emitted when the user right-clicks the toolbar or uses the keybinding to display a popup menu.

Application developers should handle this signal if they want to display a context menu on the toolbar. The context-menu should appear at the coordinates given by x and y. The mouse button number is given by the button parameter. If the menu was popped up using the keybaord, button is -1.

Parameters:

  | x | The x coordinate of the point where the menu should appear.
  | y | The y coordinate of the point where the menu should appear.
  | button | The mouse button the user pressed, or -1 true if the signal was handled, false if not.

Prototype:
  `bool on_my_popup_context_menu(int x, int y, int button_number)`

Glib::SignalProxy1< void,ToolbarStyle > Gtk::Toolbar::signal_toolbar_style_changed | ( |  | ) |

Emitted when the style of the toolbar changes.

Parameters:

  | @style | The new ToolbarStyle of the toolbar.

Prototype:
  `void on_my_toolbar_style_changed(ToolbarStyle style)`

void Gtk::Toolbar::unset_drop_highlight_item | ( |  | ) |

void Gtk::Toolbar::unset_icon_size | ( |  | ) |

Unsets toolbar icon size set with set_icon_size(), so that user preferences will be used to determine the icon size.

Since gtkmm 2.12:

void Gtk::Toolbar::unset_toolbar_style | ( |  | ) |
