## Documentation
The heart of ESPUI is
[ESPAsyncWebserver](https://github.com/me-no-dev/ESPAsyncWebServer). ESPUI's
frontend is based on [Skeleton CSS](http://getskeleton.com/) and jQuery-like
lightweight [zepto.js](https://zeptojs.com/) for handling events. The
communication between the ESP and the client browser works using web
sockets. ESPUI does not need network access and can be used in standalone access
point mode, all resources are loaded directly from the ESPs memory.
This section will explain in detail how the Library is to be used from the
Arduino code side. In the arduino `setup()` routine the interface can be customised by adding UI Elements.
This is done by calling the corresponding library methods on the Library object
`ESPUI`. Eg: `ESPUI.button("button", &myCallback);` creates a button in the
interface that calls the `myCallback(Control *sender, int value)` function when changed. All buttons and
items call their callback whenever there is a state change from them. This means
the button will call the callback when it is pressed and also again when it is
released. To separate different events an integer number with the event name is
passed to the callback function that can be handled in a `switch(){}case{}`
statement.

This section will explain in detail how the Library is to be used from the Arduino code side. In the arduino `setup()` routine the interface can be customised by adding UI Elements. This is done by calling the corresponding library methods on the Library object `ESPUI`. Eg: `ESPUI.button("button", &myCallback);` creates a button in the interface that calls the `myCallback(Control *sender, int eventname)` function when changed. All buttons and items call their callback whenever there is a state change from them. This means the button will call the callback when it is pressed and also again when it is released. To separate different events, an integer number with the event name is passed to the callback function that can be handled in a `switch(){}case{}` statement.
<br><br>
Alternativly you may use the extended callback funtion which provides three parameters to the callback function `myCallback(Control *sender, int eventname, void * UserParameter)`. The `UserParameter` is provided as part of the `ESPUI.addControl` method set and allows the user to define contextual information that is to be presented to the callback function in an unmodified form.
<br><br>
The below example creates a button and defines a lambda function to implicitly create an `ExtendedCallback` which then invokes a more specialized button callback handler. The example uses the `UserParameter` to hold the `this` pointer to an object instance, providing a mechanism for sending the event to a specific object without the need for a switch / map / lookup translation of the Sender Id to an object reference.
```
void YourClassName::setup()
{
ButtonElementId = ESPUI.addControl(
ControlType::Button,
ButtonLabel.c_str(),
" Button Face Text ",
ControlColor::None,
ParentElementId,
[](Control *sender, int eventname, void* param)
{
if(param)
{
reinterpret_cast<YourClassName*>(param)->myButtonCallback(sender, eventname);
}
},
this); // <-Third parameter for the extended callback
// or
ButtonElementId = ESPUI.button(
" Button Face Text ",
[](Control *sender, int eventname, void* param)
{
if(param)
{
reinterpret_cast<YourClassName*>(param)->myButtonCallback(sender, eventname);
}
},
this); // <-Third parameter for the extended callback
}
```
```
void YourClassName::myButtonCallback(Control* sender, int eventname)
{
if (eventname == B_DOWN)
{
// Handle the button down event
}
else if (eventname == B_UP)
{
// Handle the button up event
}
}
```
