Question
Update a wildcard in a custom container called in a scroll wheel
In my main screen there is a scroll wheel which scrolls the contents of a custom container. The custom container has 5 wildcards. Now I intend to dynamically update those wildcards with my text resources. But I'm unable to do so. Please find my codes attached.
Screen1View.cpp
#include <gui/screen1_screen/Screen1View.hpp>
#include <texts/TextKeysAndLanguages.hpp>
void TextUpdate::updateText()
{
Unicode::snprintf(textArea1Buffer, TEXTAREA1_SIZE, "%s", touchgfx::TypedText(T_NAT_EVE1).getText());
textArea1.setWildcard(textArea1Buffer);
textArea1.setTypedText(touchgfx::TypedText(T_NAT_EVE1));
add(textArea1);
}
// Screen1View constructor
Screen1View::Screen1View()
: tickCounter(0), targetItem(0), scrollCompleted(false),
digitalHours(0), digitalMinutes(0), digitalSeconds(0),
textUpdateIntervalCounter(0), textUpdateObj() // Initialize textUpdateObj
{
}
void Screen1View::setupScreen()
{
Screen1ViewBase::setupScreen();
tickCounter = 0; // Reset the tick counter
textUpdateIntervalCounter = 0; // Reset the interval counter
targetItem = scrollWheel1.getSelectedItem(); // Initialize target item
scrollCompleted = false; // Reset scroll completion flag
digitalHours = digitalClock1.getCurrentHour();
digitalMinutes = digitalClock1.getCurrentMinute();
digitalSeconds = digitalClock1.getCurrentSecond();
}
void Screen1View::tearDownScreen()
{
Screen1ViewBase::tearDownScreen();
}
void Screen1View::handleTickEvent()
{
tickCounter++;
textUpdateIntervalCounter++;
// Scroll logic: Execute every 0.5 seconds (30 ticks at 60 Hz)
if (tickCounter % ticksPerStep == 0)
{
if (!scrollWheel1.isAnimating() && !scrollCompleted)
{
targetItem = (targetItem + 1) % scrollWheel1.getNumberOfItems();
scrollWheel1.animateToItem(targetItem, 500); // Smooth animation (500ms)
scrollCompleted = true;
}
else if (!scrollWheel1.isAnimating() && scrollCompleted)
{
scrollCompleted = false; // Reset flag when animation finishes
}
}
// Clock update logic: Execute every second
if (tickCounter % 60 == 0)
{
textUpdateObj.updateText();
if (++digitalSeconds >= 60)
{
digitalSeconds = 0;
if (++digitalMinutes >= 60)
{
digitalMinutes = 0;
if (++digitalHours >= 24)
{
digitalHours = 0;
}
}
}
digitalClock1.setTime24Hour(digitalHours, digitalMinutes, digitalSeconds);
}
// Text update logic: Execute every 2 seconds (120 ticks at 60 Hz)
if (textUpdateIntervalCounter >= 120)
{
textUpdateObj.updateText(); // Update text dynamically
textUpdateIntervalCounter = 0;
}
}
void Screen1View::resetScroll()
{
tickCounter = 0; // Reset tick counter
scrollCompleted = false; // Allow scrolling again
}

void resetScroll(); // Method to reset the scroll state
protected:
int tickCounter; // Counter to track ticks
int targetItem; // The target index for the scroll wheel
bool scrollCompleted; // Flag to ensure the scroll happens only once
static constexpr int ticksPerStep = 30; // Number of ticks for a 0.5-second delay (assuming 60 Hz)
int digitalHours;
int digitalMinutes;
int digitalSeconds;
int textUpdateIntervalCounter; // Counter for updating text every 2 seconds
TextUpdate textUpdateObj; // Object for TextUpdate
};
#endif // SCREEN1VIEW_HPP
I intend to print only in the first wildcard for the time being.
