textArea.invalidate(); makes my textArea disappear Hello there,i'm using touchgfx to show time data using touchgfx::Unicode::snprintf(textArea1Buffer, TEXTAREA1_SIZE, "%d", sec); but when I use invalidate() function to refresh the text area, the text disappear from my screen;instead, the code getRootContainer().invalidate(); works well and make things correct.by the way, the code using textArea1.invalidate(); can shown on TouchGFX simulator, it just doesn't work on my F411CEU6here is my code: uint16_t count = 0;
uint16_t sec = 0;
void Clock_screenView::handleTickEvent()
{
touchgfx::Rect Rect1;
if(count > 33)
{
touchgfx::Unicode::snprintf(textArea1Buffer, TEXTAREA1_SIZE, "%d", sec);
textArea1.invalidate();
//getRootContainer().invalidate();
count=0;
sec++;
}
else
{
count++;
}
} Is there anyone, who can explain this phenomena?Best regardsRust
