Implementations
Creates a new builder-pattern struct instance to construct ShortcutsShortcut
objects.
This method returns an instance of ShortcutsShortcutBuilder
which can be used to create ShortcutsShortcut
objects.
The size group for the accelerator portion of this shortcut.
This is used internally by GTK, and must not be modified by applications.
The accelerator(s) represented by this object.
This property is used if property::ShortcutsShortcut::shortcut-type
is set to ShortcutType::Accelerator
.
The syntax of this property is (an extension of) the syntax understood
by accelerator_parse()
. Multiple accelerators can be specified
by separating them with a space, but keep in mind that the available width
is limited.
It is also possible to specify ranges of shortcuts, using “…” between the keys. Sequences of keys can be specified using a “+” or “&” between the keys.
Examples:
- A single shortcut:
<ctl>``<alt>
delete - Two alternative shortcuts:
<shift>
a Home - A range of shortcuts:
<alt>
1…<alt>
9 - Several keys pressed together: Control_L&Control_R
- A sequence of shortcuts or keys:
<ctl>
c+<ctl>
x
Use “+” instead of “&” when the keys may (or have to be) pressed sequentially (e.g use “t+t” for ‘press the t key twice’).
Note that <, > and & need to be escaped as <, > and & when used in .ui files.

A detailed action name.
If this is set for a shortcut of type ShortcutType::Accelerator
,
then GTK will use the accelerators that are associated with the
action via GtkApplicationExt::set_accels_for_action()
, and
setting property::ShortcutsShortcut::accelerator
is not necessary.

An icon to represent the shortcut or gesture.
This property is used if property::ShortcutsShortcut::shortcut-type
is set to ShortcutType::Gesture
.
For the other predefined gesture types, GTK provides an icon on its own.

The subtitle for the shortcut or gesture.
This is typically used for gestures and should be a short, one-line text that describes the gesture itself. For the predefined gesture types, GTK provides a subtitle on its own.

This should be a short string that can fit in a single line.
