Class Details¶

class Gtk.PopoverMenu(**kwargs)¶

Bases:: Gtk.Popover
Abstract:: No

GtkPopoverMenu is a subclass of GtkPopover that implements menu behavior.

An example Gtk.PopoverMenu

GtkPopoverMenu treats its children like menus and allows switching between them. It can open submenus as traditional, nested submenus, or in a more touch-friendly sliding fashion.

GtkPopoverMenu is meant to be used primarily with menu models, using [ctor`Gtk`.PopoverMenu.new_from_model]. If you need to put other widgets such as a GtkSpinButton or a GtkSwitch into a popover, you can use [method`Gtk`.PopoverMenu.add_child].

For more dialog-like behavior, use a plain GtkPopover.

Menu models

The XML format understood by GtkBuilder for GMenuModel consists of a toplevel <menu> element, which contains one or more <item> elements. Each <item> element contains <attribute> and <link> elements with a mandatory name attribute. <link> elements have the same content model as <menu>. Instead of <link name="submenu"> or <link name="section">, you can use <submenu> or <section> elements.

``xml <menu id=’app-menu’>

<section>

<item>
<attribute name=’label’ translatable=’yes’>_New Window</attribute> <attribute name=’action’>app.new</attribute>

</item> <item>

<attribute name=’label’ translatable=’yes’>_About Sunny</attribute> <attribute name=’action’>app.about</attribute>

</item> <item>

<attribute name=’label’ translatable=’yes’>_Quit</attribute> <attribute name=’action’>app.quit</attribute>

</item>

</section>

</menu> ``

Attribute values can be translated using gettext, like other GtkBuilder content. <attribute> elements can be marked for translation with a translatable="yes" attribute. It is also possible to specify message context and translator comments, using the context and comments attributes. To make use of this, the GtkBuilder must have been given the gettext domain to use.

The following attributes are used when constructing menu items:

“label”: a user-visible string to display
“use-markup”: whether the text in the menu item includes Pango markup
“action”: the prefixed name of the action to trigger
“target”: the parameter to use when activating the action
“icon” and “verb-icon”: names of icons that may be displayed
“submenu-action”: name of an action that may be used to track whether a submenu is open
“hidden-when”: a string used to determine when the item will be hidden. Possible values include “action-disabled”, “action-missing”, “macos-menubar”. This is mainly useful for exported menus, see [method`Gtk`.Application.set_menubar].
“custom”: a string used to match against the ID of a custom child added with [method`Gtk`.PopoverMenu.add_child], [method`Gtk`.PopoverMenuBar.add_child], or in the ui file with <child type="ID">.

The following attributes are used when constructing sections:

“label”: a user-visible string to use as section heading
“display-hint”: a string used to determine special formatting for the section. Possible values include “horizontal-buttons”, “circular-buttons” and “inline-buttons”. They all indicate that section should be displayed as a horizontal row of buttons.
“text-direction”: a string used to determine the GtkTextDirection to use when “display-hint” is set to “horizontal-buttons”. Possible values include “rtl”, “ltr”, and “none”.

The following attributes are used when constructing submenus:

“label”: a user-visible string to display
“icon”: icon name to display

Menu items will also show accelerators, which are usually associated with actions via [method`Gtk`.Application.set_accels_for_action], [id`gtk_widget_class_add_binding_action`] or [method`Gtk`.ShortcutController.add_shortcut].

CSS Nodes

GtkPopoverMenu is just a subclass of GtkPopover that adds custom content to it, therefore it has the same CSS nodes. It is one of the cases that add a .menu style class to the main popover node.

Menu items have nodes with name button and class .model. If a section display-hint is set, the section gets a node box with class horizontal plus a class with the same text as the display hint. Note that said box may not be the direct ancestor of the item button``s. Thus, for example, to style items in an ``inline-buttons section, select .inline-buttons button.model. Other things that may be of interest to style in menus include label nodes.

Accessibility

GtkPopoverMenu uses the Gtk.AccessibleRole.MENU role, and its items use the Gtk.AccessibleRole.MENU_ITEM, Gtk.AccessibleRole.MENU_ITEM_CHECKBOX or Gtk.AccessibleRole.MENU_ITEM_RADIO roles, depending on the action they are connected to.

classmethod new_from_model(model)[source]¶

Parameters:: model (Gio.MenuModel or None) – a GMenuModel
Returns:: the new GtkPopoverMenu
Return type:: Gtk.Widget

Creates a GtkPopoverMenu and populates it according to model.

The created buttons are connected to actions found in the GtkApplicationWindow to which the popover belongs - typically by means of being attached to a widget that is contained within the ``GtkApplicationWindow``s widget hierarchy.

Actions can also be added using [method`Gtk`.Widget.insert_action_group] on the menus attach widget or on any of its parent widgets.

This function creates menus with sliding submenus. See [ctor`Gtk`.PopoverMenu.new_from_model_full] for a way to control this.

classmethod new_from_model_full(model, flags)[source]¶

Parameters:

model (Gio.MenuModel) – a GMenuModel
flags (Gtk.PopoverMenuFlags) – flags that affect how the menu is created

Returns:

the new GtkPopoverMenu

Return type:

Gtk.Widget

Creates a GtkPopoverMenu and populates it according to model.

The created buttons are connected to actions found in the action groups that are accessible from the parent widget. This includes the GtkApplicationWindow to which the popover belongs. Actions can also be added using [method`Gtk`.Widget.insert_action_group] on the parent widget or on any of its parent widgets.

The only flag that is supported currently is Gtk.PopoverMenuFlags.NESTED, which makes GTK create traditional, nested submenus instead of the default sliding submenus.

add_child(child, id)[source]¶

Parameters:

child (Gtk.Widget) – the GtkWidget to add
id (str) – the ID to insert child at

Returns:

True if id was found and the widget added

Return type:

bool

Adds a custom widget to a generated menu.

For this to work, the menu model of self must have an item with a custom attribute that matches id.

get_menu_model()[source]¶

Returns:: the menu model of self
Return type:: Gio.MenuModel or None

Returns the menu model used to populate the popover.

remove_child(child)[source]¶

Parameters:: child (Gtk.Widget) – the GtkWidget to remove
Returns:: True if the widget was removed
Return type:: bool

Removes a widget that has previously been added with [method`Gtk`.PopoverMenu.add_child()]

set_menu_model(model)[source]¶

Parameters:: model (Gio.MenuModel or None) – a GMenuModel

Sets a new menu model on self.

The existing contents of self are removed, and the self is populated with new contents according to model.
