Struct qt_gui::q_opengl_framebuffer_object::FramebufferRestorePolicy

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

This enum type is used to configure the behavior related to restoring framebuffer bindings when calling blitFramebuffer().

C++ enum: QOpenGLFramebufferObject::FramebufferRestorePolicy.

C++ documentation:

This enum type is used to configure the behavior related to restoring framebuffer bindings when calling blitFramebuffer().

This enum was introduced or modified in Qt 5.7.

Implementations

impl FramebufferRestorePolicy

pub fn to_int(&self) -> c_int

impl FramebufferRestorePolicy

pub const DontRestoreFramebufferBinding: FramebufferRestorePolicy = _

Do not restore the previous framebuffer binding. The caller is responsible for tracking and setting the framebuffer binding as needed. (C++ enum variant: DontRestoreFramebufferBinding = 0)

pub const RestoreFramebufferBindingToDefault: FramebufferRestorePolicy = _

After the blit operation, bind the default framebuffer. (C++ enum variant: RestoreFramebufferBindingToDefault = 1)

pub const RestoreFrameBufferBinding: FramebufferRestorePolicy = _

Restore the previously bound framebuffer. This is potentially expensive because of the need to query the currently bound framebuffer. (C++ enum variant: RestoreFrameBufferBinding = 2)

Trait Implementations

impl Clone for FramebufferRestorePolicy

fn clone(&self) -> FramebufferRestorePolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FramebufferRestorePolicy

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

Formats the value using the given formatter.

impl From<FramebufferRestorePolicy> for c_int

fn from(value: FramebufferRestorePolicy) -> Self

Converts to this type from the input type.

impl From<i32> for FramebufferRestorePolicy

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for FramebufferRestorePolicy

fn eq(&self, other: &FramebufferRestorePolicy) -> 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.
