Flags for igBeginDragDropSource(), igAcceptDragDropPayload()

Implementations§

source§

impl DragDropFlags

source

pub const SOURCE_NO_PREVIEW_TOOLTIP: Self = _

By default, a successful call to igBeginDragDropSource opens a tooltip so you can display a preview or description of the source contents. This flag disable this behavior.

source

pub const SOURCE_NO_DISABLE_HOVER: Self = _

By default, when dragging we clear data so that igIsItemHovered() will return false, to avoid subsequent user code submitting tooltips. This flag disable this behavior so you can still call igIsItemHovered() on the source item.

source

pub const SOURCE_NO_HOLD_TO_OPEN_OTHERS: Self = _

Disable the behavior that allows to open tree nodes and collapsing header by holding over them while dragging a source item.

source

pub const SOURCE_ALLOW_NULL_ID: Self = _

Allow items such as igText(), igImage() that have no unique identifier to be used as drag source, by manufacturing a temporary identifier based on their window-relative position. This is extremely unusual within the dear imgui ecosystem and so we made it explicit.

source

pub const SOURCE_EXTERN: Self = _

External source (from outside of imgui), won’t attempt to read current item/window info. Will always return true. Only one Extern source can be active simultaneously.

source

pub const SOURCE_AUTO_EXPIRE_PAYLOAD: Self = _

Automatically expire the payload if the source ceases to be submitted (otherwise payloads are persisting while being dragged)

source

pub const ACCEPT_BEFORE_DELIVERY: Self = _

igAcceptDragDropPayload() will returns true even before the mouse button is released. You can then call igIsDelivery() to test if the payload needs to be delivered.

source

pub const ACCEPT_NO_DRAW_DEFAULT_RECT: Self = _

Do not draw the default highlight rectangle when hovering over target.

source

pub const ACCEPT_NO_PREVIEW_TOOLTIP: Self = _

Request hiding the igBeginDragDropSource tooltip from the igBeginDragDropTarget site.

source

pub const ACCEPT_PEEK_ONLY: Self = _

For peeking ahead and inspecting the payload before delivery. This is just a convenience flag for the intersection of ACCEPT_BEFORE_DELIVERY and ACCEPT_NO_DRAW_DEFAULT_RECT

source

pub const fn empty() -> Self

Returns an empty set of flags.

source

pub const fn all() -> Self

Returns the set containing all flags.

source

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

source

pub const fn from_bits(bits: u32) -> Option<Self>

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

source

pub const fn from_bits_truncate(bits: u32) -> Self

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

source

pub const unsafe fn from_bits_unchecked(bits: u32) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

§Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

source

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

source

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

source

pub const fn intersects(&self, other: Self) -> bool

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

source

pub const fn contains(&self, other: Self) -> bool

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

source

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

source

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

source

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

source

pub fn set(&mut self, other: Self, value: bool)

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

source

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

source

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

source

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

source

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

source

pub const fn complement(self) -> Self

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
