ScrollList : Change Color/Draw rectangle Selected item

[Karan 123]

Hi,

I am using scroll List and also able to select the item by clicking that and tested that on simulator. Please check below image .

Screen1View::Screen1View() :
	scrollList1ItemSelectedCallback(this, &Screen1View::scrollList1ItemSelectedHandler)	    
{
 
}
void Screen1View::scrollList1ItemSelectedHandler(int16_t itemSelected)
{
	touchgfx_printf("Item Selected = %d \r\n" ,itemSelected) ;
	touchgfx_printf(Rx_Buffer1[itemSelected]) ;
      // Which API should I use ..
	touchgfx_printf(" \r\n" ) ;
}
 
void Screen1View::setupScreen()
 {
	  Screen1ViewBase::setupScreen();
	  scrollList1.setItemSelectedCallback(scrollList1ItemSelectedCallback);  // Added
 
}

How do I change color of Clicked Item (Text) or put rectangle over that .

Means which API should I use .?

Hello,

Here is an example on how to modify elements of an item (change color, change text, etc.) in a ScrollList when this item is being clicked.

Hope this will help.

Thanks for your appreciation ..

But As I have worked on LED,Button with FreeRTOS for Interfacing with hardware in TouchGFX Applications single bit .

ADC , UART as well .

But How to send USB File Names from (2D Array or any other means) to List items with FreeRTOS Queue .

I don't find any demo like that.

2DArray_USB_FILE_Names_Queue_Model_Presenter_View_List_Item.

Can you look attached file ... is it the right way ?
