UIManager

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

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

Note

Do not confuse the GtkUIManager UI Definitions described here with the similarly named GtkBuilder UI Definitions.

<!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 accelerators (true|false) #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 always-show-image (true|false) #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.

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.

<hr>

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.

<hr>

Accelerators

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

<hr>

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.

<hr>

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.

<hr>

GtkUIManager as GtkBuildable

The GtkUIManager implementation of the GtkBuildable interface accepts GtkActionGroup objects as &lt;child&gt; elements in UI definitions.

A GtkUIManager UI definition as described above can be embedded in an GtkUIManager &lt;object&gt; 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.

classInstallProperty
void classInstallProperty(GObjectClass* oclass, uint propertyId, ParamSpec pspec)

Installs a new property. This is usually done in the class initializer. Note that it is possible to redefine a property in a derived class, by installing a property with the same name. This can be useful at times, e.g. to change the range of allowed values or the default value.

classInstallProperties
void classInstallProperties(GObjectClass* oclass, ParamSpec[] pspecs)

Installs new properties from an array of GParamSpecs. This is usually done in the class initializer. The property id of each property is the index of each GParamSpec in the pspecs array. The property id of 0 is treated specially by GObject and it should not be used to store a GParamSpec. This function should be used if you plan to use a static array of GParamSpecs and g_object_notify_by_pspec(). For instance, this Since 2.26

classFindProperty
ParamSpec classFindProperty(GObjectClass* oclass, string propertyName)

Looks up the GParamSpec for a property of a class.

classListProperties
ParamSpec[] classListProperties(GObjectClass* oclass)

Get an array of GParamSpec* for all properties of a class.

classOverrideProperty
void classOverrideProperty(GObjectClass* oclass, uint propertyId, string name)

Registers property_id as referring to a property with the name name in a parent class or in an interface implemented by oclass. This allows this class to override a property implementation in a parent class or to provide the implementation of a property from an interface. Note Internally, overriding is implemented by creating a property of type GParamSpecOverride; generally operations that query the properties of the object class, such as g_object_class_find_property() or g_object_class_list_properties() will return the overridden property. However, in one case, the construct_properties argument of the constructor virtual function, the GParamSpecOverride is passed instead, so that the param_id field of the GParamSpec will be correct. For virtually all uses, this makes no difference. If you need to get the overridden property, you can call g_param_spec_get_redirect_target(). Since 2.4

interfaceInstallProperty
void interfaceInstallProperty(void* iface, ParamSpec pspec)

Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property. This function is meant to be called from the interface's default vtable initialization function (the class_init member of GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface. Since 2.4

interfaceFindProperty
ParamSpec interfaceFindProperty(void* iface, string propertyName)

Find the GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek(). Since 2.4

interfaceListProperties
ParamSpec[] interfaceListProperties(void* iface)

Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek(). Since 2.4

doref
void* doref(void* object)

Increases the reference count of object.

unref
void unref(void* object)

Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

refSink
void* refSink(void* object)

Increase the reference count of object, and possibly remove the floating reference, if object has a floating reference. In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one. Since 2.10

clearObject
void clearObject(ObjectG objectPtr)

Clears a reference to a GObject. object_ptr must not be NULL. If the reference is NULL then this function does nothing. Otherwise, the reference count of the object is decreased and the pointer is set to NULL. This function is threadsafe and modifies the pointer atomically, using memory barriers where needed. A macro is also included that allows this function to be used without pointer casts. Since 2.28

isFloating
int isFloating(void* object)

Checks whether object has a floating reference. Since 2.10

forceFloating
void forceFloating()

This function is intended for GObject implementations to re-enforce a floating object reference. Doing this is seldom required: all GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink(). Since 2.10

weakRef
void weakRef(GWeakNotify notify, void* data)

Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive). Note that the weak references created by this method are not thread-safe: they cannot safely be used in one thread if the object's last g_object_unref() might happen in another thread. Use GWeakRef if thread-safety is required.

weakUnref
void weakUnref(GWeakNotify notify, void* data)

Removes a weak reference callback to an object.

addWeakPointer
void addWeakPointer(void** weakPointerLocation)

Adds a weak reference from weak_pointer to object to indicate that the pointer located at weak_pointer_location is only valid during the lifetime of object. When the object is finalized, weak_pointer will be set to NULL. Note that as with g_object_weak_ref(), the weak references created by this method are not thread-safe: they cannot safely be used in one thread if the object's last g_object_unref() might happen in another thread. Use GWeakRef if thread-safety is required.

removeWeakPointer
void removeWeakPointer(void** weakPointerLocation)

Removes a weak reference from object that was previously added using g_object_add_weak_pointer(). The weak_pointer_location has to match the one used with g_object_add_weak_pointer().

addToggleRef
void addToggleRef(GToggleNotify notify, void* data)

Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established. This functionality is intended for binding object to a proxy object managed by another memory manager. This is done with two paired references: the strong reference added by g_object_add_toggle_ref() and a reverse reference to the proxy object which is either a strong reference or weak reference. The setup is that when there are no other references to object, only a weak reference is held in the reverse direction from object to the proxy object, but when there are other references held to object, a strong reference is held. The notify callback is called when the reference from object to the proxy object should be toggled from strong to weak (is_last_ref true) or weak to strong (is_last_ref false). Since a (normal) reference must be held to the object before calling g_object_add_toggle_ref(), the initial state of the reverse link is always strong. Multiple toggle references may be added to the same gobject, however if there are multiple toggle references to an object, none of them will ever be notified until all but one are removed. For this reason, you should only ever use a toggle reference if there is important state in the proxy object. Since 2.8

removeToggleRef
void removeToggleRef(GToggleNotify notify, void* data)

Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one. Since 2.8

notify
void notify(string propertyName)

Emits a "notify" signal for the property property_name on object. When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

notifyByPspec
void notifyByPspec(ParamSpec pspec)

Emits a "notify" signal for the property specified by pspec on object. This function omits the property name lookup, hence it is faster than g_object_notify(). One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with Since 2.26

freezeNotify
void freezeNotify()

Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one "notify" signal is emitted for each property modified while the object is frozen. This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

thawNotify
void thawNotify()

Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted. Duplicate notifications for each property are squashed so that at most one "notify" signal is emitted for each property. It is an error to call this function when the freeze count is zero.

getData
void* getData(string key)

Gets a named field from the objects table of associations (see g_object_set_data()).

setData
void setData(string key, void* data)

Each object carries around a table of associations from strings to pointers. This function lets you set an association. If the object already had an association with that name, the old association will be destroyed.

setDataFull
void setDataFull(string key, void* data, GDestroyNotify destroy)

Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed. Note that the destroy callback is not called if data is NULL.

stealData
void* stealData(string key)

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

dupData
void* dupData(string key, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_data() which returns a 'duplicate' of the value. dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object. If the key is not set on the object then dup_func will be called with a NULL argument. Note that dup_func is called while user data of object is locked. This function can be useful to avoid races when multiple threads are using object data on the same key on the same object. Since 2.34

replaceData
int replaceData(string key, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify* oldDestroy)

Compares the user data for the key key on object with oldval, and if they are the same, replaces oldval with newval. This is like a typical atomic compare-and-exchange operation, for user data on an object. If the previous value was replaced then ownership of the old value (oldval) is passed to the caller, including the registered destroy notify for it (passed out in old_destroy). Its up to the caller to free this as he wishes, which may or may not include using old_destroy as sometimes replacement should not destroy the object in the normal way. Return: TRUE if the existing value for key was replaced by newval, FALSE otherwise. Since 2.34

getQdata
void* getQdata(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata().

setQdata
void setQdata(GQuark quark, void* data)

This sets an opaque, named pointer on an object. The name is specified through a GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the object with g_object_get_qdata() until the object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.

setQdataFull
void setQdataFull(GQuark quark, void* data, GDestroyNotify destroy)

This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with data as argument when the object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same quark.

stealQdata
void* stealQdata(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update

dupQdata
void* dupQdata(GQuark quark, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object. If the quark is not set on the object then dup_func will be called with a NULL argument. Note that dup_func is called while user data of object is locked. This function can be useful to avoid races when multiple threads are using object data on the same key on the same object. Since 2.34

replaceQdata
int replaceQdata(GQuark quark, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify* oldDestroy)

Compares the user data for the key quark on object with oldval, and if they are the same, replaces oldval with newval. This is like a typical atomic compare-and-exchange operation, for user data on an object. If the previous value was replaced then ownership of the old value (oldval) is passed to the caller, including the registered destroy notify for it (passed out in old_destroy). Its up to the caller to free this as he wishes, which may or may not include using old_destroy as sometimes replacement should not destroy the object in the normal way. Return: TRUE if the existing value for quark was replaced by newval, FALSE otherwise. Since 2.34

setProperty
void setProperty(string propertyName, Value value)

Sets a property on an object.

getProperty
void getProperty(string propertyName, Value value)

Gets a property of an object. value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init(). In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset(). Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

setValist
void setValist(string firstPropertyName, void* varArgs)

Sets properties on an object.

getValist
void getValist(string firstPropertyName, void* varArgs)

Gets properties of an object. In general, a copy is made of the property contents and the caller is responsible for freeing the memory in the appropriate manner for the type, for instance by calling g_free() or g_object_unref(). See g_object_get().

watchClosure
void watchClosure(Closure closure)

This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

runDispose
void runDispose()

Releases all references to other objects. This can be used to break reference cycles. This functions should only be called from object system implementations.

From BuildableIF

getBuildableTStruct
GtkBuildable* getBuildableTStruct()

Get the main Gtk struct

getStruct
void* getStruct()

the main Gtk struct as a void*

buildableSetName
void buildableSetName(string name)

Sets the name of the buildable object. Since 2.12

buildableGetName
string buildableGetName()

Gets the name of the buildable object. GtkBuilder sets the name based on the GtkBuilder UI definition used to construct the buildable. Since 2.12

addChild
void addChild(Builder builder, ObjectG child, string type)

Adds a child to buildable. type is an optional string describing how the child should be added. Since 2.12

setBuildableProperty
void setBuildableProperty(Builder builder, string name, Value value)

Sets the property name name to value on the buildable object. Since 2.12

constructChild
ObjectG constructChild(Builder builder, string name)

Constructs a child of buildable with the name name. GtkBuilder calls this function if a "constructor" has been specified in the UI definition. Since 2.12

customTagStart
int customTagStart(Builder builder, ObjectG child, string tagname, GMarkupParser* parser, void** data)

This is called for each unknown element under &lt;child&gt;. Since 2.12

customTagEnd
void customTagEnd(Builder builder, ObjectG child, string tagname, void** data)

This is called at the end of each custom element handled by the buildable. Since 2.12

customFinished
void customFinished(Builder builder, ObjectG child, string tagname, void* data)

This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable. Since 2.12

parserFinished
void parserFinished(Builder builder)

Called when the builder finishes the parsing of a GtkBuilder UI definition. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder. Since 2.12

getInternalChild
ObjectG getInternalChild(Builder builder, string childname)

Get the internal child called childname of the buildable object. Since 2.12
