// Helpers for asynchronously executing a base::[Once|Repeating]Closure (bound
|
|
// function or method) on a CEF thread. Creation of a
|
|
// base::[Once|Repeating]Closure can be facilitated using
|
|
// base::Bind[Once|Repeating]. See include/base/cef_callback.h for complete
|
|
// usage instructions.
|
|
//
|
|
// To use these helpers you should include this header and the header that
|
|
// defines base::Bind[Once|Repeating].

// Example of executing a bound function:
|
|
//
|
|
// // Define a function.
|
|
// void MyFunc(int arg) { /* do something with |arg| on the UI thread */ }
|
|
//
|
|
// // Post a task that will execute MyFunc on the UI thread and pass an |arg|
|
|
// // value of 5.
|
|
// CefPostTask(TID_UI, base::BindOnce(&MyFunc, 5));
|
|
//
|
|
// Example of executing a bound method:
|
|
//
|
|
// // Define a class.
|
|
// class MyClass : public CefBaseRefCounted {
|
|
// public:
|
|
// MyClass() {}
|
|
// void MyMethod(int arg) { /* do something with |arg| on the UI thread */ }
|
|
// private:
|
|
// IMPLEMENT_REFCOUNTING(MyClass);

// // Create an instance of MyClass.
|

// CefRefPtr<MyClass> instance = new MyClass();

// // Post a task that will execute MyClass::MyMethod on the UI thread and pass

// // an |arg| value of 5. |instance| will be kept alive until after the task
|
|
// // completes.
