Expand description

Flags used to define the behaviour of a Application.

Implementations§

source§

impl ApplicationFlags

source

pub const FLAGS_NONE: Self = _

Default. Deprecated in 2.74, use G_APPLICATION_DEFAULT_FLAGS instead

source

pub const IS_SERVICE: Self = _

Run as a service. In this mode, registration fails if the service is already running, and the application will initially wait up to 10 seconds for an initial activation message to arrive.

source

pub const IS_LAUNCHER: Self = _

Don’t try to become the primary instance.

source

pub const HANDLES_OPEN: Self = _

This application handles opening files (in the primary instance). Note that this flag only affects the default implementation of local_command_line(), and has no effect if HANDLES_COMMAND_LINE is given. See ApplicationExtManual::run() for details.

source

pub const HANDLES_COMMAND_LINE: Self = _

This application handles command line arguments (in the primary instance). Note that this flag only affect the default implementation of local_command_line(). See ApplicationExtManual::run() for details.

source

pub const SEND_ENVIRONMENT: Self = _

Send the environment of the launching process to the primary instance. Set this flag if your application is expected to behave differently depending on certain environment variables. For instance, an editor might be expected to use the GIT_COMMITTER_NAME environment variable when editing a git commit message. The environment is available to the command-line signal handler, via ApplicationCommandLineExt::getenv().

source

pub const NON_UNIQUE: Self = _

Make no attempts to do any of the typical single-instance application negotiation, even if the application ID is given. The application neither attempts to become the owner of the application ID nor does it check if an existing owner already exists. Everything occurs in the local process. Since: 2.30.

source

pub const CAN_OVERRIDE_APP_ID: Self = _

Allow users to override the application ID from the command line with --gapplication-app-id. Since: 2.48

source

pub const ALLOW_REPLACEMENT: Self = _

Allow another instance to take over the bus name. Since: 2.60

source

pub const REPLACE: Self = _

Take over from another instance. This flag is usually set by passing --gapplication-replace on the commandline. Since: 2.60

source§

impl ApplicationFlags

source

pub const fn empty() -> Self

Get a flags value with all bits unset.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

source

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

source

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

Convert from a bits value.

This method will return None if any unknown bits are set.

source

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

Convert from a bits value, unsetting any unknown bits.

source

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

Convert from a bits value exactly.

source

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

source

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

source

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

source

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

Whether any set bits in a source flags value are also set in a target flags value.

source

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

Whether all set bits in a source flags value are also set in a target flags value.

source

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

The bitwise or (|) of the bits in two flags values.

source

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

source

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

The bitwise exclusive-or (^) of the bits in two flags values.

source

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

Call insert when value is true or remove when value is false.

source

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

The bitwise and (&) of the bits in two flags values.

source

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

The bitwise or (|) of the bits in two flags values.

source

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

source

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

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

source§

impl ApplicationFlags

source

pub const fn iter(&self) -> Iter<ApplicationFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

source

pub const fn iter_names(&self) -> IterNames<ApplicationFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
