How to connect functions of QML files?

[Yonetici]

Hello guys,

I have 4 different QML files (Item1.qml ; Item2.qml ; Item3.qml ; Item4.qml) and a MainPage.qml file. I use them like this:

...
 
Item1 {
     id: item1
     ...
     }
 
Item2 {
     id: item2
     ...
     }
 
Item3 {
     id: item3
     ...
     }
 
Item4 {
     id: item4
     ...
     }
 
...

...

Item1 {
     id: item1
     ...
     }

Item2 {
     id: item2
     ...
     }

Item3 {
     id: item3
     ...
     }

Item4 {
     id: item4
     ...
     }

...

To copy to clipboard, switch view to plain text mode 

I added this code to my main file, MainPage.qml, and it works perfectly with my animations. However I have a problem: 4 different Item file has same function and I want to use these functions together (for example if it is a calculation function, then, I want to add my main file total calculation).

How can I connect them? Any idea?
