How to change screen with touchgfx api functions with out interactions?

[mchin.1]

I am working on touchgfx LCD. I need a a support to develop our custom application.

i have seen touchgfx API functions setup screen but i need example for better understanding.

[MM..1]

application().gotoXXXXXScreenNoTransition();

[mchin.1]

Thank you but i have seen below information

switchScreen​

virtual void switchScreen(Screen *newScreen)Switch to another Screen.Will call tearDownScreen on current Screen before switching, and subsequently call setupScreen and draw automatically for the new Screen.Parameters:newScreenA pointer to the new screen.

how can i use this to switch from one screen to other

virtual void switchScreen(Screen *newScreen)

I am not getting this gotoScreen5ScreenNoTransition() in application.gotoScreen5ScreenNoTransition(); with out interaction.

I do not want to add interaction so at that time what should i do for screen change ?

[MM..1]

I dont check 4.18 , but every screen have in application Base generated NoTransition goto. Check it. Interaction dummy you need only for animated transition changes.

[mchin.1]

I am using 4.17.0 Base generated NoTransition goto not generated when add screen only

but generated whenvever adding screen change interaction

[MM..1]

You check file FrontendApplicationBase.cpp?

[mchin.1]

yes

i checked that file

not generated Base generated NoTransition in FrontendApplicationBase.cpp if i just add screen simply.

so How can i change screen with out this application().gotoXXXXXScreenNoTransition();. finally i got a error.

I have only one no empty screen in app no interactions and file in v 4.17

i am checking Screen Transition Declarations in FrontendApplicationBase.cpp ..Is it right?

1st screen is ok but for rest of the screens i did not get so how can i change my application from screen1 to screen 2 with out interaction. i need that give me support & concept.

[MM..1]

OMG yes without interaction you need add this manualy to GUI files as everythink.

FrontendApplication.cpp

#include <gui/common/FrontendApplication.hpp>
 
FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap)
 : FrontendApplicationBase(m, heap)
{
 
}
 
add here screen 2 3 4 ...
void FrontendApplication::gotoScreen2ScreenNoTransition()
{
 transitionCallback = touchgfx::Callback<FrontendApplicationBase>(this, &FrontendApplication::gotoScreen2ScreenNoTransitionImpl);
 pendingScreenTransitionCallback = &transitionCallback;
}
 
void FrontendApplication::gotoScreen2ScreenNoTransitionImpl()
{
 touchgfx::makeTransition<Screen2View, Screen2Presenter, touchgfx::NoTransition, Model >(&currentScreen, &currentPresenter, frontendHeap, &currentTransition, &model);
}

and into hpp ...

Thank you OK Is It works ? I will tell you after try manual addition.

Please tell about this stuff how to use beacause i am very new

Thank you but i have seen below information

how can i use this to switch from one screen to other

virtual void switchScreen(Screen *newScreen)

[MM..1]

maybe try

application().switchScreen( &Screen2View );

[mchin.1]

Hi

screen changing is working fine.

i have a doubt about buttons.

If i add any button with out interaction how can i know is that button pressed or not?

Is button operation work without button interaction?
