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.
|
||||
It also possible to use a lambda function in the callback parameter. It also allows the user to define, in a more C++ way, contextual information in any form. This is shown by the [completeLambda](examples/completeLambda/completeLambda.ino) example.

* @author Ian Gray @iangray1000
|

*
|
||||
* This is an example GUI to show off all of the features of ESPUI.
|
||||
* This can be built using the Arduino IDE, or PlatformIO.
|
||||
*
|
||||
* ---------------------------------------------------------------------------------------
|
||||
* If you just want to see examples of the ESPUI code, jump down to the setUpUI() function
|
||||
* ---------------------------------------------------------------------------------------
|
||||
*
|
||||
* When this program boots, it will load an SSID and password from the EEPROM.
|
||||
* The SSID is a null-terminated C string stored at EEPROM addresses 0-31
|
||||
* The password is a null-terminated C string stored at EEPROM addresses 32-95.
|
||||
* If these credentials do not work for some reason, the ESP will create an Access
|
||||
* Point wifi with the SSID HOSTNAME (defined below). You can then connect and use
|
||||
* the controls on the "Wifi Credentials" tab to store credentials into the EEPROM.
|
||||
*
|
||||
* Version with lambdas. Comparing to version with only callbacks:

||||
* diff -u ../completeExample/completeExample.cpp completeLambda.ino|less
