|
||
* A #GtkUIManager constructs a user interface (menus and toolbars) from
|
||
* one or more UI definitions, which reference actions from one or more
|
||
* action groups.
|
||
*
|
||
* # UI Definitions # {#XML-UI}
|
||
*
|
||
* The UI definitions are specified in an XML format which can be
|
||
* roughly described by the following DTD.
|
||
*
|
||
* > Do not confuse the GtkUIManager UI Definitions described here with
|
||
* > the similarly named [GtkBuilder UI Definitions][BUILDER-UI].

|
||
* 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 #GMarkupParser is used to parse the UI description, it must not only
|
||
* be valid XML, but valid markup.
|
||
*
|
||
* 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.

|
||
*
|
||
* 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 #GtkMenuBar
|
||
*
|
||
* - toolbar
|
||
*
|
||
* a #GtkToolbar
|
||
*
|
||
* - popup
|
||
*
|
||
* a toplevel #GtkMenu
|
||
*
|
||
* - menu
|
||
*
|
||
* a #GtkMenu attached to a menuitem
|
||
*
|
||
* - menuitem
|
||
*
|
||
* a #GtkMenuItem subclass, the exact type depends on the action
|
||
*
|
||
* - toolitem
|
||
*
|
||
* a #GtkToolItem 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
|
||
* #GtkMenuToolButton as proxy.
|
||
*
|
||
* - separator
|
||
*
|
||
* a #GtkSeparatorMenuItem or #GtkSeparatorToolItem
|
||
*
|
||
* - 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 # {#UI-Merging}
|
||
*
|
||
* The most remarkable feature of #GtkUIManager 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 # {#Smart-Separators}
|
||
*
|
||
* The separators created by #GtkUIManager 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.
|
||
* #GtkUIManager 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.
|
||
*
|
||
* # GtkUIManager as GtkBuildable # {#GtkUIManager-BUILDER-UI}
|
||
*
|
||
* The GtkUIManager implementation of the GtkBuildable interface accepts
|
||
* GtkActionGroup objects as <child> elements in UI definitions.
|
||
*
|
||
* A GtkUIManager UI definition as described above can be embedded in
|
||
* an GtkUIManager <object> element in a GtkBuilder UI definition.
|
||
*
|
||
* The widgets that are constructed by a GtkUIManager can be embedded in
|
||
* other parts of the constructed user interface with the help of the
|
||
* “constructor” attribute. See the example below.
|
||
*
|
||
* ## An embedded GtkUIManager UI definition

* The path consists of the names specified in the XML description of the UI.

* the XML (e.g. <popup>) can be addressed by their XML element name

* Note that the widget found by following a path that ends in a <menu>;
|

* element is the menuitem to which the menu is attached, not the menu it

* manages.

*
|
||
* Also note that the widgets constructed by a ui manager are not tied to
