drag and drop actions

This is a bitmask of the available/preferred actions in a drag-and-drop operation.

In the compositor, the selected action is a result of matching the actions offered by the source and destination sides. "action" events with a "none" action will be sent to both source and destination if there is no match. All further checks will effectively happen on (source actions ∩ destination actions).

In addition, compositors may also pick different actions in reaction to key modifiers being pressed. One common design that is used in major toolkits (and the behavior recommended for compositors) is:

Behavior beyond that is considered implementation-dependent. Compositors may for example bind other modifiers (like Alt/Meta) or drags initiated with other buttons than BTN_LEFT to specific actions (e.g. "ask").

Implementations

impl DndAction[src]

pub const None: DndAction[src]

no action

pub const Copy: DndAction[src]

copy action

pub const Move: DndAction[src]

move action

pub const Ask: DndAction[src]

ask action

pub const fn empty() -> DndAction[src]

Returns an empty set of flags

pub const fn all() -> DndAction[src]

pub const fn bits(&self) -> u32[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<DndAction>[src]

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> DndAction[src]

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> DndAction[src]

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: DndAction) -> bool[src]

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: DndAction) -> bool[src]

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: DndAction)[src]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: DndAction)[src]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: DndAction)[src]

Toggles the specified flags in-place.

pub fn set(&mut self, other: DndAction, value: bool)[src]

Inserts or removes the specified flags depending on the passed value.
