Struct qt_core::ApplicationState

pub struct ApplicationState(/* private fields */);

This enum type is used to specify the current state of the application.

C++ enum: Qt::ApplicationState.

C++ documentation:

This enum type is used to specify the current state of the application.

The states are

This enum was introduced or modified in Qt 5.1.

The ApplicationStates type is a typedef for QFlags<ApplicationState>. It stores an OR combination of ApplicationState values.

Implementations

impl ApplicationState

pub fn to_int(&self) -> c_int

impl ApplicationState

pub const ApplicationSuspended: ApplicationState = _

The application is about to suspend. When entering this state, the application should save its state, cease all activities, and be prepared for code execution to stop. While suspended, the application can be killed at any time without further warnings (e.g. when low memory forces the OS to purge suspended applications). (C++ enum variant: ApplicationSuspended = 0)

pub const ApplicationHidden: ApplicationState = _

The application is hidden and runs in the background. This is the normal state for applications that need to do background processing, like playing music, while the user interacts with other applications. The application should free up all graphical resources when entering this state. (C++ enum variant: ApplicationHidden = 1)

pub const ApplicationInactive: ApplicationState = _

The application is visible, but not selected to be in front. On desktop platforms, this typically means that the user activated another application. On mobile platforms, it is more common to enter this state when the OS is interrupting the user with e.g. incoming calls or SMS-messages. While in this state, consider reducing CPU-intensive tasks. (C++ enum variant: ApplicationInactive = 2)

pub const ApplicationActive: ApplicationState = _

The application is visible and selected to be in front. (C++ enum variant: ApplicationActive = 4)

Trait Implementations

impl Clone for ApplicationState

fn clone(&self) -> ApplicationState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ApplicationState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ApplicationState> for c_int

fn from(value: ApplicationState) -> Self

Converts to this type from the input type.

impl From<i32> for ApplicationState

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ApplicationState

fn eq(&self, other: &ApplicationState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
