The goal of DBusMenu is to expose menus on DBus.
Main interface is documented here: @ref com::canonical::dbusmenu
]]></dox:d>
<interface name="com.canonical.dbusmenu">
<dox:d><![CDATA[
A DBus interface to expose menus on DBus.
Menu items are represented with a unique numeric id and a dictionary of
properties.
To reduce the amount of DBus traffic, a property should only be returned
if its value is not the default value.
Available properties are:
<table>
<tr>
<th>Name</th>
<th>Type</th>
<th>Description</th>
<th>Default Value</th>
</tr>
<tr>
<td>type</td>
<td>String</td>
<td>Can be one of:
- "standard": an item which can be clicked to trigger an action or
show another menu
- "separator": a separator
Vendor specific types can be added by prefixing them with
"x-<vendor>-".
</td>
<td>"standard"</td>
</tr>
<tr>
<td>label</td>
<td>string</td>
<td>Text of the item, except that:
-# two consecutive underscore characters "__" are displayed as a
single underscore,
-# any remaining underscore characters are not displayed at all,
-# the first of those remaining underscore characters (unless it is
the last character in the string) indicates that the following
character is the access key.
</td>
<td>""</td>
</tr>
<tr>
<td>enabled</td>
<td>boolean</td>
<td>Whether the item can be activated or not.</td>
<td>true</td>
</tr>
<tr>
<td>visible</td>
<td>boolean</td>
<td>True if the item is visible in the menu.</td>
<td>true</td>
</tr>
<tr>
<td>icon-name</td>
<td>string</td>
<td>Icon name of the item, following the freedesktop.org icon spec.</td>
<td>""</td>
</tr>
<tr>
<td>icon-data</td>
<td>binary</td>
<td>PNG data of the icon.</td>
<td>Empty</td>
</tr>
<tr>
<td>shortcut</td>
<td>array of arrays of strings</td>
<td>The shortcut of the item. Each array represents the key press
in the list of keypresses. Each list of strings contains a list of
modifiers and then the key that is used. The modifier strings
allowed are: "Control", "Alt", "Shift" and "Super".
- A simple shortcut like Ctrl+S is represented as:
[["Control", "S"]]
- A complex shortcut like Ctrl+Q, Alt+X is represented as:
[["Control", "Q"], ["Alt", "X"]]</td>
<td>Empty</td>
</tr>
<tr>
<td>toggle-type</td>
<td>string</td>
<td>
If the item can be toggled, this property should be set to:
- "checkmark": Item is an independent togglable item
- "radio": Item is part of a group where only one item can be
toggled at a time
- "": Item cannot be toggled
</td>
<td>""</td>
</tr>
<tr>
<td>toggle-state</td>
<td>int</td>
<td>
Describe the current state of a "togglable" item. Can be one of:
- 0 = off
- 1 = on
- anything else = indeterminate
Note:
The implementation does not itself handle ensuring that only one
item in a radio group is set to "on", or that a group does not have
"on" and "indeterminate" items simultaneously; maintaining this
policy is up to the toolkit wrappers.
</td>
<td>-1</td>
</tr>
<tr>
<td>children-display</td>
<td>string</td>
<td>
If the menu item has children this property should be set to
"submenu".
</td>
<td>""</td>
</tr>
<tr>
<td>disposition</td>
<td>string</td>
<td>
How the menuitem feels the information it's displaying to the
user should be presented.
- "normal" a standard menu item
- "informative" providing additional information to the user
- "warning" looking at potentially harmful results
- "alert" something bad could potentially happen
</td>
<td>"normal"</td>
</tr>
</table>
Vendor specific properties can be added by prefixing them with
"x-<vendor>-".
]]></dox:d>
<!-- Properties -->
<property name="Version" type="u" access="read">
<dox:d>
Provides the version of the DBusmenu API that this API is
implementing.
</dox:d>
</property>
<property name="TextDirection" type="s" access="read">
<dox:d>
Represents the way the text direction of the application. This
allows the server to handle mismatches intelligently. For left-
to-right the string is "ltr" for right-to-left it is "rtl".
</dox:d>
</property>
<property name="Status" type="s" access="read">
<dox:d>
Tells if the menus are in a normal state or they believe that they
could use some attention. Cases for showing them would be if help
were referring to them or they accessors were being highlighted.
This property can have two values: "normal" in almost all cases and
"notice" when they should have a higher priority to be shown.
</dox:d>
</property>
<property name="IconThemePath" type="as" access="read">
<dox:d>
A list of directories that should be used for finding icons using
the icon naming spec. Idealy there should only be one for the icon
theme, but additional ones are often added by applications for
app specific icons.
</dox:d>
</property>
<!-- Functions -->
<method name="GetLayout">
<dox:d>
Provides the layout and propertiers that are attached to the entries
that are in the layout. It only gives the items that are children
of the item that is specified in @a parentId. It will return all of the
properties or specific ones depending of the value in @a propertyNames.
The format is recursive, where the second 'v' is in the same format
as the original 'a(ia{sv}av)'. Its content depends on the value
of @a recursionDepth.
</dox:d>
<arg type="i" name="parentId" direction="in">
<dox:d>The ID of the parent node for the layout. For
grabbing the layout from the root node use zero.</dox:d>
</arg>
<arg type="i" name="recursionDepth" direction="in">
<dox:d>
The amount of levels of recursion to use. This affects the
content of the second variant array.
- -1: deliver all the items under the @a parentId.
- 0: no recursion, the array will be empty.
- n: array will contains items up to 'n' level depth.
</dox:d>
</arg>
<arg type="as" name="propertyNames" direction="in" >
<dox:d>
The list of item properties we are
interested in. If there are no entries in the list all of
the properties will be sent.
</dox:d>
</arg>
<arg type="u" name="revision" direction="out">
<dox:d>The revision number of the layout. For matching
with layoutUpdated signals.</dox:d>
</arg>
<arg type="(ia{sv}av)" name="layout" direction="out">
<dox:d>The layout, as a recursive structure.</dox:d>
</arg>
</method>
<method name="GetGroupProperties">
<dox:d>
Returns the list of items which are children of @a parentId.
</dox:d>
<arg type="ai" name="ids" direction="in" >
<dox:d>
A list of ids that we should be finding the properties
on. If the list is empty, all menu items should be sent.
</dox:d>
</arg>
<arg type="as" name="propertyNames" direction="in" >
<dox:d>
The list of item properties we are
interested in. If there are no entries in the list all of
the properties will be sent.
</dox:d>
</arg>
<arg type="a(ia{sv})" name="properties" direction="out" >
<dox:d>
An array of property values.
An item in this area is represented as a struct following
this format:
@li id unsigned the item id
@li properties map(string => variant) the requested item properties
</dox:d>
</arg>
</method>
<method name="GetProperty">
<dox:d>
Get a signal property on a single item. This is not useful if you're
going to implement this interface, it should only be used if you're
debugging via a commandline tool.
</dox:d>
<arg type="i" name="id" direction="in">

<term>filters a(sa(us))</term>
<listitem>
<para>
List of serialized file filters.
</para>
<para>
Each item in the array specifies a single filter to offer to the user.
The first string is a user-visible name for the filter. The a(us)
specifies a list of filter strings, which can be either a glob-style pattern
(indicated by 0) or a mimetype (indicated by 1). Patterns are case-sensitive.
To match different capitalizations of, e.g. '*.ico', use a pattern like
'*.[iI][cC][oO]'.
</para>
<para>
Example: [('Images', [(0, '*.ico'), (1, 'image/png')]), ('Text', [(0, '*.txt')])]
</para>
<para>
Note that filters are purely there to aid the user in making a useful selection.
The portal may still allow the user to select files that don't match any filter
criteria, and applications must be prepared to handle that.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>current_filter (sa(us))</term>
<listitem><para>
Request that this filter be set by default at dialog creation. If
the filters list is nonempty, it should match a filter in the
list to set the default filter from the list. Alternatively, it
may be specified when the list is empty to apply the filter
unconditionally.
</para></listitem>
</varlistentry>
<varlistentry>
<term>choices a(ssa(ss)s)</term>
<listitem>
<para>
List of serialized combo boxes to add to the file chooser.
</para>
<para>
For each element, the first string is an ID that will be returned
with the response, the second string is a user-visible label. The
a(ss) is the list of choices, each being an ID and a
user-visible label. The final string is the initial selection,
or "", to let the portal decide which choice will be initially selected.
None of the strings, except for the initial selection, should be empty.
</para>
<para>
As a special case, passing an empty array for the list of choices
indicates a boolean choice that is typically displayed as a check
button, using "true" and "false" as the choices.
</para>
<para>
Example: [('encoding', 'Encoding', [('utf8', 'Unicode (UTF-8)'), ('latin15', 'Western')], 'latin15'), ('reencode', 'Reencode', [], 'false')]

org.freedesktop.portal.Request:
@short_description: Shared request interface
The Request interface is shared by all portal interfaces. When a
portal method is called, the reply includes a handle (i.e. object path)
for a Request object, which will stay alive for the duration of the
user interaction related to the method call.
The portal indicates that a portal request interaction is over by
emitting the #org.freedesktop.portal.Request::Response signal on the
Request object.
The application can abort the interaction calling
org.freedesktop.portal.Request.Close() on the Request object.
Since version 0.9 of xdg-desktop-portal, the handle will be of the form
/org/freedesktop/portal/desktop/request/SENDER/TOKEN,
where SENDER is the callers unique name, with the initial ':' removed and
all '.' replaced by '_', and TOKEN is a unique token that the caller provided
with the handle_token key in the options vardict.
This change was made to let applications subscribe to the Response signal before
making the initial portal call, thereby avoiding a race condition. It is recommended
that the caller should verify that the returned handle is what it expected, and update
its signal subscription if it isn't. This ensures that applications will work with both
old and new versions of xdg-desktop-portal.
The token that the caller provides should be unique and not guessable. To avoid clashes
with calls made from unrelated libraries, it is a good idea to use a per-library prefix
combined with a random number.
