Struct CacheModeFlag

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

This enum describes the flags that you can set for a QGraphicsView's cache mode.

C++ enum: QGraphicsView::CacheModeFlag.

C++ documentation:

This enum describes the flags that you can set for a QGraphicsView’s cache mode.

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

See also cacheMode.

Implementations

impl CacheModeFlag

pub fn to_int(&self) -> c_int

impl CacheModeFlag

pub const CacheNone: CacheModeFlag

All painting is done directly onto the viewport. (C++ enum variant: CacheNone = 0)

pub const CacheBackground: CacheModeFlag

The background is cached. This affects both custom backgrounds, and backgrounds based on the backgroundBrush property. When this flag is enabled, QGraphicsView will allocate one pixmap with the full size of the viewport. (C++ enum variant: CacheBackground = 1)

Trait Implementations

impl<T: Into<QFlags<CacheModeFlag>>> BitOr<T> for CacheModeFlag

type Output = QFlags<CacheModeFlag>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<CacheModeFlag>

Performs the | operation.

impl Clone for CacheModeFlag

fn clone(&self) -> CacheModeFlag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheModeFlag

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

Formats the value using the given formatter.

impl From<CacheModeFlag> for QFlags<CacheModeFlag>

fn from(value: CacheModeFlag) -> Self

Converts to this type from the input type.

impl From<CacheModeFlag> for c_int

fn from(value: CacheModeFlag) -> Self

Converts to this type from the input type.

impl From<i32> for CacheModeFlag

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for CacheModeFlag

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

Tests for self and other values to be equal, and is used by ==.

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

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