Struct zng :: gesture :: ShortcutsHandle Copy item path

impl ShortcutsHandle

pub fn dummy() -> ShortcutsHandle

Create dummy handle that is always in the released state.

Note that Option<ShortcutsHandle> takes up the same space as ShortcutsHandle and avoids an allocation.

pub fn perm(self)

Drops the handle but does not release.

The claim stays registered for the duration of the app or until another handle calls release. Note that shortcut claims only work if the target widget is found and is not BLOCKED.

pub fn is_permanent(&self) -> bool

If another handle has called perm.

If true the claim will stay active until the app exits, unless release is called.

pub fn release(self)

Drops the handle and releases the claim

pub fn is_released(&self) -> bool

If another handle has called release.

The claim is already dropped or will be dropped in the next app update, this is irreversible.

pub fn downgrade(&self) -> WeakShortcutsHandle

Create a weak handle.
