Method Descriptions

GetProcAddress(String)

Get an EGL library function by name.

If an EGL library is loaded, this function allows applications to get entry points for EGL functions. This is useful to provide to an EGL API and extension loader.

class function GetProcAddress(const AProc: String): Pointer; inline; static

Parameters

AProc: String : The name of an EGL function.

Returns

Pointer: A pointer to the named EGL function. The returned pointer should be cast to the appropriate function signature.

SetAttributeCallbacks(TSdlEglAttribArrayCallback, TSdlEglIntArrayCallback, TSdlEglIntArrayCallback)

Sets the callbacks for defining custom EGLAttrib arrays for EGL initialization.

Callbacks that aren't needed can be set to nil.

NOTE: These callback pointers will be reset after TSdlGL.ResetAttributes.

class procedure SetAttributeCallbacks(const APlatformAttribCallback: TSdlEglAttribArrayCallback; const ASurfaceAttribCallback, AContextAttribCallback: TSdlEglIntArrayCallback); static

Parameters

APlatformAttribCallback: TSdlEglAttribArrayCallback : Callback for attributes to pass to eglGetPlatformDisplay. May be nil.

ASurfaceAttribCallback: TSdlEglIntArrayCallback : Callback for attributes to pass to eglCreateSurface. May be nil.

AContextAttribCallback: TSdlEglIntArrayCallback : Callback for attributes to pass to eglCreateContext. May be nil.
