If the overflow menu is visible when this function it called, the menu will be rebuilt.

The function must be called when the tool item changes what it will do in response to the Gtk::ToolItem::create-menu-proxy signal.

Since gtkmm 2.6:

const Widget* Gtk::ToolItem::retrieve_proxy_menu_item | ( |  | ) | const

Returns the Gtk::MenuItem that was last set by set_proxy_menu_item(), ie.

the Gtk::MenuItem that is going to appear in the overflow menu.

Since gtkmm 2.4:

Returns:
  The Gtk::MenuItem that is going to appear in the overflow menu for tool_item.

Widget* Gtk::ToolItem::retrieve_proxy_menu_item | ( |  | ) |

Returns the Gtk::MenuItem that was last set by set_proxy_menu_item(), ie.

the Gtk::MenuItem that is going to appear in the overflow menu.

Since gtkmm 2.4:

Returns:
  The Gtk::MenuItem that is going to appear in the overflow menu for tool_item.

void Gtk::ToolItem::set_expand | ( | bool | expand = `true` | ) |

Sets whether tool_item is allocated extra space when there is more room on the toolbar then needed for the items.

The effect is that the item gets bigger when the toolbar gets bigger and smaller when the toolbar gets smaller.

Since gtkmm 2.4:

Parameters:

  expand | Whether tool_item is allocated extra space.

void Gtk::ToolItem::set_homogeneous | ( | bool | homogeneous = `true` | ) |

Sets whether tool_item is to be allocated the same size as other homogeneous items.

The effect is that all homogeneous items will have the same width as the widest of the items.

Since gtkmm 2.4:

Parameters:

  homogeneous | Whether tool_item is the same size as other homogeneous items.

void Gtk::ToolItem::set_is_important | ( | bool | is_important = `true` | ) |

Sets whether tool_item should be considered important.

The Gtk::ToolButton class uses this property to determine whether to show or hide its label when the toolbar style is Gtk::TOOLBAR_BOTH_HORIZ. The result is that only tool buttons with the "is_important" property set have labels, an effect known as "priority text"

Since gtkmm 2.4:

Parameters:

  is_important | Whether the tool item should be considered important.

void Gtk::ToolItem::set_proxy_menu_item | ( | const Glib::ustring & | menu_item_id,
|  | Widget& | menu_item
| ) |  |

Sets the Gtk::MenuItem used in the toolbar overflow menu.

The menu_item_id is used to identify the caller of this function and should also be used with get_proxy_menu_item().

Since gtkmm 2.4:

Parameters:

  menu_item_id | A string used to identify menu_item.
  menu_item | A Gtk::MenuItem to be used in the overflow menu.

void Gtk::ToolItem::set_tooltip_markup | ( | const Glib::ustring & | markup | ) |

Sets the markup text to be displayed as tooltip on the item.

See Gtk::Widget::set_tooltip_markup().

Since gtkmm 2.12:

Parameters:

  markup | Markup text to be used as tooltip for tool_item.

Reimplemented from Gtk::Widget.

void Gtk::ToolItem::set_tooltip_text | ( | const Glib::ustring & | text | ) |

Sets the text to be displayed as tooltip on the item.

See Gtk::Widget::set_tooltip_text().

Since gtkmm 2.12:

Parameters:

  text | Text to be used as tooltip for tool_item.

Reimplemented from Gtk::Widget.

void Gtk::ToolItem::set_use_drag_window | ( | bool | use_drag_window = `true` | ) |

Sets whether tool_item has a drag window.

When `true` the toolitem can be used as a drag source through Gtk::DragSource::set(). When tool_item has a drag window it will intercept all events, even those that would otherwise be sent to a child of tool_item.

Since gtkmm 2.4:

Parameters:

  use_drag_window | Whether tool_item has a drag window.

void Gtk::ToolItem::set_visible_horizontal | ( | bool | visible_horizontal = `true` | ) |

Sets whether tool_item is visible when the toolbar is docked horizontally.

Since gtkmm 2.4:

Parameters:

  visible_horizontal | Whether tool_item is visible when in horizontal mode.

void Gtk::ToolItem::set_visible_vertical | ( | bool | visible_vertical = `true` | ) |

Sets whether tool_item is visible when the toolbar is docked vertically.

Some tool items, such as text entries, are too wide to be useful on a vertically docked toolbar. If visible_vertical is `false` tool_item will not appear on toolbars that are docked vertically.

Since gtkmm 2.4:

Parameters:

  visible_vertical | Whether tool_item is visible when the toolbar is in vertical mode.

Glib::SignalProxy0< bool > Gtk::ToolItem::signal_create_menu_proxy | ( |  | ) |

This signal is emitted when the toolbar needs information from about whether the item should appear in the toolbar overflow menu.

In response the tool item should either <itemizedlist> <listitem> call set_proxy_menu_item() with a NULL pointer and return true to indicate that the item should not appear in the overflow menu </listitem> <listitem> call set_proxy_menu_item() with a new menu item and return true, or </listitem> <listitem> return false to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item. </listitem> </itemizedlist>

The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call rebuild_menu() to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.

Returns:
  true if the signal was handled, false if not

Prototype:
  `bool on_my_create_menu_proxy()`

Glib::SignalProxy0< void > Gtk::ToolItem::signal_toolbar_reconfigured | ( |  | ) |

This signal is emitted when some property of the toolbar that the item is a child of changes.

For custom subclasses of ToolItem, the default handler of this signal use the functions <itemizedlist> <listitem>Toolbar::get_orientation()</listitem> <listitem>Toolbar::get_style()</listitem> <listitem>Toolbar::get_icon_size()</listitem> <listitem>Toolbar::get_relief_style()</listitem> </itemizedlist> to find out what the toolbar should look like and change themselves accordingly.

Prototype:
  `void on_my_toolbar_reconfigured()`

void Gtk::ToolItem::toolbar_reconfigured | ( |  | ) |

Emits the signal Gtk::ToolItem::toolbar_reconfigured on tool_item.

Gtk::Toolbar and other Gtk::ToolShell implementations use this function to notify children, when some aspect of their configuration changes.

Since gtkmm 2.14:
