# FTXUI Template
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Template example using the [FTXUI](https://github.com/ArthurSonzogni/FTXUI) library with a proper logger, thread-safe event handler and multiple pages paradigm. This template can be used in any project and is a good way to start a project using a simple and not-so-verbose approach.
|
|
|
|
## Build the project
|
|
|
|
You can simply use CMake with the following commands:
|
|
|
|
```bash
|
|
mkdir build && cd build
|
|
cmake ..
|
|
cmake --build . --parallel
|
|
```
|
|
|
|
## Using the Interface
|
|
|
|
### Event
|
|
|
|
Main thread-safe event handler. You can set a custom function in it that will be called once the
|
|
loop is starting. It is recommended to run the eventhandler in a separated thread.
|
|
|
|
Each event that is added or handled is thread safe.
|
|
|
|
_main.cpp_
|
|
```cpp
|
|
|
|
static inline void loop_event(EventHandler &handler, const EventPayload &payload)
|
|
{
|
|
// Called each time there is a new event in the event buffer...
|
|
}
|
|
|
|
int main(void)
|
|
{
|
|
// Basic usage
|
|
EventHandler handler;
|
|
handler.set_handler(loop_event);
|
|
Page1 page1(handler);
|
|
// Starting the event loop in a separated thread.
|
|
std::thread t_event(&EventHandler::loop, &handler);
|
|
t_event.join();
|
|
return 0;
|
|
}
|
|
```
|
|
|
|
_page1.cpp_
|
|
```cpp
|
|
void Page1::change_screen()
|
|
{
|
|
this->send_event(EventType::SWITCH_SCREEN, static_cast<size_t>(1));
|
|
}
|
|
```
|
|
|
|
### Logger
|
|
|
|
_'Logger'_ is a general Logger that can be instanciated anywhere as a singleton. It can have a maximum size for its buffer that can be changed on the go. Each LoggerType can be gathered from each data which can lead to multiple ways to print out a log.
|
|
|
|
```cpp
|
|
Logger& logger = Logger::GetInstance();
|
|
logger.push_back("Hello, world!", LoggerType::PRINT);
|
|
// std::vector<std::string>& buffer = logger.get_buffer();
|
|
```
|
|
|
|
### UserInterface
|
|
|
|
_'UserInterface'_ is the main object that can be instanciated anywhere as a singleton you can add any pages to it and cycle through them using the select_screen function.
|
|
|
|
```cpp
|
|
UserInterface &ui = UserInterface::GetInstance();
|
|
|
|
int main(void)
|
|
{
|
|
// Event declaration
|
|
EventHandler handler;
|
|
|
|
// Page declaration
|
|
PageX pagex(handler);
|
|
// other pages...
|
|
|
|
ui.add_screen(&pagex);
|
|
// other pages...
|
|
|
|
ui.start();
|
|
return 0;
|
|
}
|
|
```
|
|
|
|
## Creating a new page
|
|
|
|
To create a new page, just create a parent class from `Page` and create a `ftxui::Component` named `_page` in the constructor. You can follow the examples given in the [pages folder](src/pages). |
