Make this->context() the current context for current block. The context is released when the return variable is destroyed. The "context object" uses this->makeCurrent() and this->doneCurrent() , hence it's compatible with enclosed scopes, and only the first created context object dtor eventually release OpenGL context.
Example
if (test){
auto context = viewer->activateScopedContext();
Texture tex;
tex->initializeGL();
}

void Ra::Gui::WindowQt::doneCurrent

Release this->context() . This results in no context being current in the current thread. In case a context has been made current multiple times, this function just deacrease the internal counter by one.

void Ra::Gui::WindowQt::makeCurrent
(
)
Make this->context() the current context. This function is made reentrant thanks to an internal counter that count how many time the context has been asked to be activated. If the context have already been made current with a previous call to makeCurrent, this function increase an internal counter by one so that doneCurrent do not release the context.
