# Gtk::Action Class Reference

Inheritance diagram for Gtk::Action:

[legend]

List of all members.

## Detailed Description

An action which can be triggered by a menu or toolbar item.

Actions represent operations that the user can perform, along with some information about how it should be presented in the user interface. Each action provides methods to create icons, menu items and toolbar items representing itself.

As well as the callback that is called when the action is activated, the following is also associated with the action:

- a name (not translated, for path lookup)
- a label (translated, for display)
- an accelerator
- whether the label indicates a stock id
- a tooltip (optional, translated)
- a toolbar label (optional, shorter than label)

The action will also have some state information:

- visible (shown/hidden)
- sensitive (enabled/disabled)

Apart from regular actions, there are toggle actions, which can be toggled between two states and radio actions, of which only one in a group can be in the "active" state. Other actions can be implemented as Gtk::Action subclasses.

Each action can have one or more proxy menu item, toolbar button or other proxy widgets. Proxies mirror the state of the action (text label, tooltip, icon, visible, sensitive, etc), and should change when the action's state changes. When the proxy is activated, it should activate its action.

## Member Function Documentation

void Gtk::Action::activate | ( |  | ) |

Emits the "activate" signal on the specified action, if it isn't insensitive.

This gets called by the proxy widgets when they get activated.

It can also be used to manually activate an action.

Since gtkmm 2.4:

void Gtk::Action::block_activate_from | ( | Widget& | proxy | ) | `[protected]`

Disables calls to the activate() function by signals on the given proxy widget.

This is used to break notification loops for things like check or radio actions.

This function is intended for use by action implementations.

Since gtkmm 2.4:

Parameters:

  | proxy | A proxy widget.

void Gtk::Action::connect_accelerator | ( |  | ) |

Installs the accelerator for action if action has an accel path and group.

See set_accel_path() and set_accel_group()

Since multiple proxies may independently trigger the installation of the accelerator, the action counts the number of times this function has been called and doesn't remove the accelerator until disconnect_accelerator() has been called as many times.

Since gtkmm 2.4:

void Gtk::Action::connect_proxy | ( | Widget& | proxy | ) |

Connects a widget to an action object as a proxy.

Synchronises various properties of the action with the widget (such as label text, icon, tooltip, etc), and attaches a callback so that the action gets activated when the proxy widget does.

If the widget is already connected to an action, it is disconnected first.

Since gtkmm 2.4:

Parameters:

  | proxy | The proxy widget.

virtual void Gtk::Action::connect_proxy_vfunc | ( | Widget* | proxy | ) | `[protected, virtual]`

static Glib::RefPtr<Action> Gtk::Action::create | ( | const Glib::ustring & | name,

|  | const Glib::ustring & | tooltip = `Glib::ustring()` |
| ) |  |  | `[static]`

Creates an action with a stock ID.

The stock ID is used to set a default icon, text and accelerator for the action.

Parameters:

  | name | A unique name for the action.
  | stock_id | The stock icon to display in widgets representing the action.
  | label | The label displayed in menu items and on buttons.
  | tooltip | A tooltip for the action.

void Gtk::Action::set_sensitive | ( | bool | sensitive = `true` | ) |

Sets the sensitive property of the action to sensitive.

Note that this doesn't necessarily mean effective sensitivity. See is_sensitive() for that.

Since gtkmm 2.6:

Parameters:

  | sensitive | `true` to make the action sensitive.

void Gtk::Action::set_tooltip | ( | const Glib::ustring & | tooltip | ) |

void Gtk::Action::set_visible | ( | bool | visible = `true` | ) |

Sets the visible property of the action to visible.

Note that this doesn't necessarily mean effective visibility. See is_visible() for that.

Since gtkmm 2.6:

Parameters:

  | visible | `true` to make the action visible.

Glib::SignalProxy0< void > Gtk::Action::signal_activate | ( |  | ) |

The "activate" signal is emitted when the action is activated.

Prototype:
  `void on_my_activate()`

void Gtk::Action::unblock_activate_from | ( | Widget& | proxy | ) | `[protected]`

Re-enables calls to the activate() function by signals on the given proxy widget.

This undoes the blocking done by block_activate_from().

This function is intended for use by action implementations.

Since gtkmm 2.4:

Parameters:

  | proxy | A proxy widget.
