Trait containing all GLDisplay methods.

Implementors

crate::GLDisplay

Required methods

fn add_context<P: IsA<GLContext>>(&self, context: &P) -> Result<(), BoolError>[src]

context

a crate::GLContext

Returns

whether context was successfully added. false may be returned if there already exists another context for context’s active thread.

Must be called with the object lock held.

fn create_context<P: IsA<GLContext>>(
    &self,
    other_context: &P
) -> Result<GLContext, Error>[src]

It requires the display’s object lock to be held.

other_context

other crate::GLContext to share resources with.

p_context

resulting crate::GLContext

Returns

whether a new context could be created.

fn create_window(&self) -> Result<GLWindow, BoolError>[src]

Returns

a new crate::GLWindow for self or None.

fn filter_gl_api(&self, gl_api: GLAPI)[src]

limit the use of OpenGL to the requested gl_api. This is intended to allow application and elements to request a specific set of OpenGL API’s based on what they support. See [crate::prelude::GLContextExt::get_gl_api()] for the retrieving the API supported by a crate::GLContext.

gl_api

a crate::GLAPI to filter with

fn gl_api(&self) -> GLAPI[src]

see Self::filter_gl_api() for what the returned value represents

Returns

the crate::GLAPI configured for self

fn gl_api_unlocked(&self) -> GLAPI[src]

fn handle_type(&self) -> GLDisplayType[src]

Returns

the crate::GLDisplayType of self

fn remove_context<P: IsA<GLContext>>(&self, context: &P)[src]

This is supported on crate feature v1_18 only.

Must be called with the object lock held.

context

the crate::GLContext to remove

fn remove_window<P: IsA<GLWindow>>(&self, window: &P) -> Result<(), BoolError>[src]

window

a crate::GLWindow to remove

Returns

if window could be removed from self

fn connect_create_context<F: Fn(&Self, &GLContext) -> GLContext + Send + Sync + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]

Overrides the crate::GLContext (XXX: @-reference does not belong to GLDisplayExt!) creation mechanism. It can be called in any thread and it is emitted with display’s object lock held.

context

other context to share resources with.

Returns

the new context.
