Detailed Description

Constructing menus and toolbars from an XML description.

A Gtk::UIManager constructs a user interface (menus and toolbars) from one or more UI definitions, which reference actions from one or more action groups.

UI Definitions

The UI definitions are specified in an XML format which can be roughly described by the following DTD.

<!ELEMENT ui          (menubar|toolbar|popup|accelerator)* >
<!ELEMENT menubar     (menuitem|separator|placeholder|menu)* >
<!ELEMENT menu        (menuitem|separator|placeholder|menu)* >
<!ELEMENT popup       (menuitem|separator|placeholder|menu)* >
<!ELEMENT toolbar     (toolitem|separator|placeholder)* >
<!ELEMENT placeholder (menuitem|toolitem|separator|placeholder|menu)* >
<!ELEMENT menuitem     EMPTY >
<!ELEMENT toolitem     (menu?) >
<!ELEMENT separator    EMPTY >
<!ELEMENT accelerator  EMPTY >
<!ATTLIST menubar      name                  #IMPLIED
                     action                #IMPLIED >
<!ATTLIST toolbar      name                  #IMPLIED
                     action                #IMPLIED >
<!ATTLIST popup        name                  #IMPLIED
                     action                #IMPLIED >
<!ATTLIST placeholder  name                  #IMPLIED
                      action                #IMPLIED >
<!ATTLIST separator    name                  #IMPLIED
                      action                #IMPLIED
                      expand   (true|false) #IMPLIED >
<!ATTLIST menu         name                  #IMPLIED
                      action                #REQUIRED
                      position (top|bot)    #IMPLIED >
<!ATTLIST menuitem     name                  #IMPLIED
                     action                #REQUIRED
                     position (top|bot)    #IMPLIED >
<!ATTLIST toolitem     name                  #IMPLIED
                     action                #REQUIRED
                     position (top|bot)    #IMPLIED >
<!ATTLIST accelerator  name                  #IMPLIED
                      action                #REQUIRED >

There are some additional restrictions beyond those specified in the DTD, e.g. every toolitem must have a toolbar in its anchestry and every menuitem must have a + menubar or popup in its anchestry. Since a GMarkup parser is used to parse the UI description, it must not only be valid XML, but valid GMarkup.

If a name is not specified, it defaults to the action. If an action is not specified either, the element name is used. The name and action attributes must not contain '/' characters after parsing (since that would mess up path lookup) and must be usable as XML attributes when enclosed in doublequotes, thus they must not '"' characters or references to the " entity.

Example: UI Definition: <ui>

<menubar>

<menu name="FileMenu" action="FileMenuAction">

<menuitem name="New" action="New2Action" />

<placeholder name="FileMenuAdditions" />

</menu>

<menu name="JustifyMenu" action="JustifyMenuAction">

<menuitem name="Left" action="justify-left"/>

<menuitem name="Centre" action="justify-center"/>

<menuitem name="Right" action="justify-right"/>

<menuitem name="Fill" action="justify-fill"/>

</menu>

</menubar>

<toolbar action="toolbar1">

<placeholder name="JustifyToolItems">

<separator/>

<toolitem name="Left" action="justify-left"/>

<toolitem name="Centre" action="justify-center"/>

<toolitem name="Right" action="justify-right"/>

<toolitem name="Fill" action="justify-fill"/>

<separator/>

</placeholder>

</toolbar>

</ui>

The constructed widget hierarchy is very similar to the element tree of the XML, with the exception that placeholders are merged into their parents. The correspondence of XML elements to widgets should be almost obvious:

menubar a Gtk::MenuBar
toolbar a Gtk::Toolbar
popup a toplevel Gtk::Menu
menu a Gtk::Menu attached to a menuitem
menuitem a Gtk::MenuItem subclass, the exact type depends on the action
toolitem a Gtk::ToolItem subclass, the exact type depends on the action. Note that toolitem elements may contain a menu element, but only if their associated action specifies a Gtk::MenuToolButton as proxy.
separator a Gtk::SeparatorMenuItem or Gtk::SeparatorToolItem
accelerator a keyboard accelerator

The "position" attribute determines where a constructed widget is positioned wrt. to its siblings in the partially constructed tree. If it is "top", the widget is prepended, otherwise it is appended.

UI Merging

The most remarkable feature of Gtk::UIManager is that it can overlay a set of menuitems and toolitems over another one, and demerge them later.

Merging is done based on the names of the XML elements. Each element is identified by a path which consists of the names of its anchestors, separated by slashes. For example, the menuitem named "Left" in the example above has the path /ui/menubar/JustifyMenu/Left and the toolitem with the same name has path /ui/toolbar1/JustifyToolItems/Left.

Accelerators

Every action has an accelerator path. Accelerators are installed together with menuitem proxies, but they can also be explicitly added with <accelerator> elements in the UI definition. This makes it possible to have accelerators for actions even if they have no visible proxies.

Smart Separators

The separators created by Gtk::UIManager are "smart", i.e. they do not show up in the UI unless they end up between two visible menu or tool items. Separators which are located at the very beginning or end of the menu or toolbar containing them, or multiple separators next to each other, are hidden. This is a useful feature, since the merging of UI elements from multiple sources can make it hard or impossible to determine in advance whether a separator will end up in such an unfortunate position.

For separators in toolbars, you can set expand="true" to turn them from a small, visible separator to an expanding, invisible one. Toolitems following an expanding separator are effectively right-aligned.

Empty Menus

Submenus pose similar problems to separators inconnection with merging. It is impossible to know in advance whether they will end up empty after merging. Gtk::UIManager offers two ways to treat empty submenus:

make them disappear by hiding the menu item they're attached to
add an insensitive "Empty" item

The behaviour is chosen based on the "hide_if_empty" property of the action to which the submenu is associated.

Since gtkmm 2.4:

Deprecated:: Use Gtk::Builder instead.
The menus and toolbars examples in the Programming with gtkmm 3 book show how to construct menus and toolbars with Gtk::Builder.

◆ signal_actions_changed()

Glib::SignalProxy< void > Gtk::UIManager::signal_actions_changed ( )

Slot Prototype:: void on_my_actions_changed()

Flags: Run First, No Recurse

The signal_actions_changed() signal is emitted whenever the set of actions changes.

Since gtkmm 2.4:

Deprecated: 3.10

Deprecated:: There is no corresponding replacement when using Gtk::Builder.

◆ signal_add_widget()

Glib::SignalProxy< void, Widget * > Gtk::UIManager::signal_add_widget ( )

Slot Prototype:: void on_my_add_widget(Widget* widget)

Flags: Run First, No Recurse

The signal_add_widget() signal is emitted for each generated menubar and toolbar. It is not emitted for generated popup menus, which can be obtained by gtk_ui_manager_get_widget().

Since gtkmm 2.4:

Deprecated: 3.10

Deprecated:: There is no corresponding replacement when using Gtk::Builder.

Parameters

widget The added widget.

◆ signal_connect_proxy()

Glib::SignalProxy< void, const Glib::RefPtr< Action > &, Widget * > Gtk::UIManager::signal_connect_proxy ( )

Slot Prototype:: void on_my_connect_proxy(const Glib::RefPtr<Action>& action, Widget* widget)

Flags: Run First, No Recurse

The signal_connect_proxy() signal is emitted after connecting a proxy to an action in the group.

This is intended for simple customizations for which a custom action class would be too clumsy, e.g. showing tooltips for menuitems in the statusbar.

Since gtkmm 2.4:

Deprecated: 3.10

Deprecated:: There is no corresponding replacement when using Gtk::Builder.

Parameters

action	The action.
widget	The proxy.

◆ signal_disconnect_proxy()

Glib::SignalProxy< void, const Glib::RefPtr< Action > &, Widget * > Gtk::UIManager::signal_disconnect_proxy ( )

Slot Prototype:: void on_my_disconnect_proxy(const Glib::RefPtr<Action>& action, Widget* widget)

Flags: Run First, No Recurse

The signal_disconnect_proxy() signal is emitted after disconnecting a proxy from an action in the group.

Since gtkmm 2.4:

Deprecated: 3.10

Deprecated:: There is no corresponding replacement when using Gtk::Builder.

Parameters

action	The action.
widget	The proxy.

◆ signal_post_activate()

Glib::SignalProxy< void, const Glib::RefPtr< Action > & > Gtk::UIManager::signal_post_activate ( )

Slot Prototype:: void on_my_post_activate(const Glib::RefPtr<Action>& action)

Flags: Run First, No Recurse

The signal_post_activate() signal is emitted just after the action is activated.

This is intended for applications to get notification just after any action is activated.

Since gtkmm 2.4:

Deprecated: 3.10

Deprecated:: There is no corresponding replacement when using Gtk::Builder.

Parameters

action The action.

◆ signal_pre_activate()

Glib::SignalProxy< void, const Glib::RefPtr< Action > & > Gtk::UIManager::signal_pre_activate ( )
