TextArea in container move animation flickering

nme · ‎2023-07-07

Hello,

I made some test to realize a scrolling text, to do it I use :

Here my container code.cpp :

#include <gui/containers/Cont_Rolling_Text.hpp>

Cont_Rolling_Text::Cont_Rolling_Text():
    TextMoveAnimationEndedCallback(this, &Cont_Rolling_Text::TextMoveAnimationEndedHandler)
{
     /* setup animation */
    textArea1.startMoveAnimation(-textArea1.getWidth(), -8, 400, &EasingEquations::linearEaseNone);
    textArea1.setMoveAnimationEndedAction(TextMoveAnimationEndedCallback);
}


void Cont_Rolling_Text::TextMoveAnimationEndedHandler(const touchgfx::MoveAnimator<TextAreaWithOneWildcard>& b)
{
    /* reset it's position */
    textArea1.moveTo(0,-8);    
    /* reset animation */   
    textArea1.startMoveAnimation(-textArea1.getWidth(), -8, 500, &EasingEquations::linearEaseNone); 
    textArea1.setMoveAnimationEndedAction(TextMoveAnimationEndedCallback);
 
}


void Cont_Rolling_Text::initialize()
{
    Cont_Rolling_TextBase::initialize();
}

And .hpp

class Cont_Rolling_Text : public Cont_Rolling_TextBase
{
public:
    Cont_Rolling_Text();
    virtual ~Cont_Rolling_Text() {}

    virtual void initialize();
      void TextMoveAnimationEndedHandler(const touchgfx::MoveAnimator<TextAreaWithOneWildcard>& b);
    
    
protected:
  touchgfx::Callback <Cont_Rolling_Text, const touchgfx::MoveAnimator<TextAreaWithOneWildcard>&> TextMoveAnimationEndedCallback; 
};

It works well but on my screen text is flickering a little during animation

Have you any clues about this issue ?

Regards,

Nicolas
