Struct qt_core::EventPriority

source ·
pub struct EventPriority(/* private fields */);
Expand description

This enum can be used to specify event priorities.

C++ enum: Qt::EventPriority.

C++ documentation:

This enum can be used to specify event priorities.

Note that these values are provided purely for convenience, since event priorities can be any value between INT_MAX and INT_MIN, inclusive. For example, you can define custom priorities as being relative to each other:

enum CustomEventPriority { // An important event ImportantEventPriority = Qt::HighEventPriority,

// A more important event MoreImportantEventPriority = ImportantEventPriority + 1,

// A critical event CriticalEventPriority = 100 * MoreImportantEventPriority,

// Not that important StatusEventPriority = Qt::LowEventPriority,

// These are less important than Status events IdleProcessingDoneEventPriority = StatusEventPriority - 1 };

See also QCoreApplication::postEvent().

Implementations§

source§

impl EventPriority

source

pub fn to_int(&self) -> c_int

source§

impl EventPriority

source

pub const HighEventPriority: EventPriority = _

Events with this priority are sent before events with NormalEventPriority or LowEventPriority. (C++ enum variant: HighEventPriority = 1)

source

pub const NormalEventPriority: EventPriority = _

Events with this priority are sent after events with HighEventPriority, but before events with LowEventPriority. (C++ enum variant: NormalEventPriority = 0)

source

pub const LowEventPriority: EventPriority = _

Events with this priority are sent after events with HighEventPriority or NormalEventPriority. (C++ enum variant: LowEventPriority = -1)
