I want to receive the callback function from the button of "Container" by generating an event from "Screens".

[mSH.1]

hello​

I want to receive the callback function from the button of "Container" by generating an event from "Screens".

The following is the definition of Callback Function for Button in Container.

// @ Container
 
void CC_Pop_Cancel_Check::flexButton_confirm_event()
{
    // Override and implement this function in CC_Pop_Cancel_Check
}
 
void CC_Pop_Cancel_Check::flexButton_cancel_event()
{
    // Override and implement this function in CC_Pop_Cancel_Check
}

Below are Screens inserted into Container.

#include <gui/scrautoremain_i1_screen/ScrAutoReMain_i1View.hpp>
#include <texts/TextKeysAndLanguages.hpp>
#include "BitmapDatabase.hpp"
 
ScrAutoReMain_i1View::ScrAutoReMain_i1View() 
{
 
}
 
void ScrAutoReMain_i1View::setupScreen()
{
    ScrAutoReMain_i1ViewBase::setupScreen();
}
 
void ScrAutoReMain_i1View::tearDownScreen()
{
    ScrAutoReMain_i1ViewBase::tearDownScreen();
}

I want to receive the callback function generated from the button of the container from the scene in the event method.

​thank.

Maybe just lost in translation, but you don't "receive" a callback function: you provide the function, and it gets called by the system on the specified event.

hello, Andrew Neil (Community Member)

It was implemented by reading the button state of the container periodically with handleTickEvent() of screens.

Is this best?

Sorry - what was implemented?

[mSH.1]

hello Andrew Neil 

By adding get and set functions to the container, a function that can get the button state from screens was added.

// @ Container
 
void CC_Pop_Cancel_Check::flexButton_confirm_event()
{
    button = 1;
}
 
void CC_Pop_Cancel_Check::flexButton_cancel_event()
{
      button = 2;
}
 
int CC_Pop_Cancel_Check::getPop_button()
{
	return button_start_check;
}
void CC_Pop_Cancel_Check::setPop_button( int data_s )
{
	button_start_check = data_s;
}

In screens, the get function of the container is read periodically through handleTickEvent() and the state of the button is checked.

#include <gui/scrautoremain_i1_screen/ScrAutoReMain_i1View.hpp>
#include <texts/TextKeysAndLanguages.hpp>
#include "BitmapDatabase.hpp"
 
ScrAutoReMain_i1View::ScrAutoReMain_i1View() 
{
 
}
void ScrAutoReMain_i1View::setupScreen()
{
    ScrAutoReMain_i1ViewBase::setupScreen();
}
 
void ScrAutoReMain_i1View::tearDownScreen()
{
    ScrAutoReMain_i1ViewBase::tearDownScreen();
}
 
 
 
void ScrAutoReMain_i1View::handleTickEvent()
{
     container.getPop_button();                   <-  Periodically check the button state
 
}

First of all, I checked that the above configuration works well, but I have a question about whether this method is effective.

thank​

So what's that got to do with callbacks?

[mSH.1]

hello Andrew Neil 

I couldn't find a way to pass the container callback function to the screen as an event, so I implemented it by polling as follows.

So what I want to know is if callback is possible.. And the method I made is efficient.
