Struct DragDropFlags

pub struct DragDropFlags { /* private fields */ }

Flags for igBeginDragDropSource(), igAcceptDragDropPayload()

Implementations

impl DragDropFlags

pub const SOURCE_NO_PREVIEW_TOOLTIP: DragDropFlags

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.

pub const SOURCE_NO_DISABLE_HOVER: DragDropFlags

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.

pub const SOURCE_NO_HOLD_TO_OPEN_OTHERS: DragDropFlags

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

pub const SOURCE_ALLOW_NULL_ID: DragDropFlags

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.

pub const SOURCE_EXTERN: DragDropFlags

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.

pub const SOURCE_AUTO_EXPIRE_PAYLOAD: DragDropFlags

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

pub const ACCEPT_BEFORE_DELIVERY: DragDropFlags

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.

pub const ACCEPT_NO_DRAW_DEFAULT_RECT: DragDropFlags

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

pub const ACCEPT_NO_PREVIEW_TOOLTIP: DragDropFlags

Request hiding the igBeginDragDropSource tooltip from the igBeginDragDropTarget site.

pub const ACCEPT_PEEK_ONLY: DragDropFlags

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

pub const fn empty() -> DragDropFlags

Returns an empty set of flags.

pub const fn all() -> DragDropFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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) -> DragDropFlags

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

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

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.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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

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

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.

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

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.

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

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.

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

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.

pub const fn complement(self) -> DragDropFlags

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.
