Change scrollwheel content by a button in TouchGFX.

[Karim]

Hi,

Is it possible to change the content of a scrollwheel by a button in the same screen.

For example I have 3 options Menu 1, Menu 2 and Menu 3 in scrollwheel when the screen appears for the firs time. I want to change these options to Menu 4 ~ Menu 6 by clicking a button in same screen.

Is there any other solution?

Thank you everyone.

you can do , what you need write into

scrollWheelUpdateItem(MenuElement& item, int16_t itemIndex)

thank you for your reply.

Yes I your are right and I already use it. I defined scrollWheelUpdateItem in screenview.cpp and it updates the content when change the screen from other screen to this screen.

But I want change the content by clicking a Button in current screen. (By defining an interaction for example)

Into button action place

markervariable=4;
scrollwhell.invalidate

and in

scrollWheelUpdateItem(MenuElement& item, int16_t itemIndex)
{
if (markervariable == 4)
 {
 
 }
else {
actual code or any other change what show
 
}
}
