/*
|
|
Used to asynchronously run an HTTP request.
|
|
Displays a simple animation on the UI to show the application hasn't frozen. Can be canceled by the user pressing B.
|
|
|
|
Usage example:
|
|
std::shared_ptr<HttpReq> httpreq = std::make_shared<HttpReq>("cdn.garcya.us", "/wp-content/uploads/2010/04/TD250.jpg");
|
|
AsyncReqComponent* req = new AsyncReqComponent(mWindow, httpreq,
|
|
[] (std::shared_ptr<HttpReq> r)
|
|
{
|
|
LOG(LogInfo) << "Request completed";
|
|
LOG(LogInfo) << " error, if any: " << r->getErrorMsg();
|
|
}, [] ()
|
|
{
|
|
LOG(LogInfo) << "Request canceled";
|
|
});
|
|
|
|
mWindow->pushGui(req);
|
|
//we can forget about req, since it will always delete itself
|
