Struct qt_core::EventPriority

#[repr(transparent)]pub struct EventPriority(_);

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
};

Methods

impl EventPriority

pub fn to_int(&self) -> c_int

impl EventPriority

pub const HighEventPriority: EventPriority

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

pub const NormalEventPriority: EventPriority

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

pub const LowEventPriority: EventPriority

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