Expand description
This enum is used with Keymap::modifier_mask()
in order to determine what modifiers the
currently used windowing system backend uses for particular
purposes. For example, on X11/Windows, the Control key is used for
invoking menu shortcuts (accelerators), whereas on Apple computers
it’s the Command key (which correspond to ModifierType::CONTROL_MASK
and
ModifierType::MOD2_MASK
, respectively).
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
PrimaryAccelerator
the primary modifier used to invoke menu accelerators.
ContextMenu
the modifier used to invoke context menus. Note that mouse button 3 always triggers context menus. When this modifier is not 0, it additionally triggers context menus when used with mouse button 1.
ExtendSelection
the modifier used to extend selections
using modifier
-click or modifier
-cursor-key
ModifySelection
the modifier used to modify selections, which in most cases means toggling the clicked item into or out of the selection.
NoTextInput
when any of these modifiers is pressed, the key event cannot produce a symbol directly. This is meant to be used for input methods, and for use cases like typeahead search.
ShiftGroup
the modifier that switches between keyboard groups (AltGr on X11/Windows and Option/Alt on OS X).
DefaultModMask
The set of modifier masks accepted as modifiers in accelerators. Needed because Command is mapped to MOD2 on OSX, which is widely used, but on X11 MOD2 is NumLock and using that for a mod key is problematic at best. Ref: https://bugzilla.gnome.org/show_bug.cgi?id=736125.
