How can initiate custom value for Screen in TouchGFX

Simply in any Screen1View.cpp use in function

void Screen1View::setupScreen()

{

  Screen1ViewBase::setupScreen();

//example

   Unicode::snprintf(textAreaVerBuffer, TEXTAREAVER_SIZE, "1.%d", VERSION);

   textAreaVer.setWildcard(textAreaVerBuffer);

   textAreaVer.invalidate();

,,,

any other object change and invalidate

Thanks for your respond.

I have it, but start up screen seem start before I get value form model, where I store and read data

Unicode::snprintf(txtMainStartTimeOxyHourBuffer,TXTMAINSTARTTIMEOXYHOUR_SIZE,"%d",presenter->getOxyStartHour());

Unicode::snprintf(txtMainStartTimeOxyMinuteBuffer,TXTMAINSTARTTIMEOXYMINUTE_SIZE,"%02d",presenter->getOxyStartMinute());

before Screen turnoff I have been save data in the model, so when start i will read data from eeprom, and in model i will update it for screen.

Do we have another way?

Thanks and best regards

Model isnt good place for load presets. Better is main before oskernelstart or when you need model use make all object invisible in setupScreen.

Then after load change it to visible. But this cant be handled in model. You need refresh variable and manipulate objects on screen in void Screen1View::handleTickEvent()

That mean I can make extern variable from main, and extern it in Screen, which i need use this variable
