actually am trying to pass a string which is defined in model.cpp

up to presenter i can able to pass the whole string but when am passing to the view only i can able to get only first character...why this issue

void Model::tick()

{

tickCounter++;

char buff[20] = "hello hai";

if (modelListener != NULL)

modelListener->notifythetext(buff);

}

modellistener.hpp:

 virtual void notifythetext(char*) {}

presenter.cpp:

void Screen1Presenter::notifythetext(char *buff) {

view.newnotify(*buff);

}

presenter.hpp

 virtual void notifythetext(char*);

view.cpp:

void Screen1View::newnotify(char buff)

{ 

  touchgfx::Unicode::UnicodeChar dst[20];

  Unicode::snprintf(textArea1Buffer, 20, "%s", textArea1Buffer, dst);

  textArea1.invalidate();

  textArea1.setWildcard(textArea1Buffer);

  textArea1.resizeToCurrentText();

  textArea1.invalidate();

}

view.hpp:

 virtual void newnotify(char);

Inside of the function void Screen1View::newnotify(char buff) you never copy buff into dst using the Unicode::strncpy() function.

I got stuck at this part of program but after reading the code you posted I could fix the issue.
