How to get the property value in another qml file(within same level).

[useryy2]

I have 2 files: file1.qml and file2.qml in same level folder.

file1:

import QtQuick 1.0

Rectangle{
    id: f1
    property int a: f2.a
}

file2:

import QtQuick 1.0

Rectangle{
    id: f2
    property int a: 1
}

When running, it notes me "Can't find variable: f2". I've also tried "file2.a" in file1.qml

Question is: How to get the property value in f2 from f1?

When you define a new type in a separate file, the first letter in the file name must be capitalized.
Rename your files to File1.qml, File2.qml

File1.qml

import QtQuick 1.0

Rectangle{
    property int a: 1
}

File2.qml

import QtQuick 1.0

Rectangle{
    property int a: f1.a
}

main.qml

    // must contain:
    File1 { id: f1 }

I will try it. - Fails
Any more rules about it? Where can I get them?

Hi I don't think properties defined in file1 can access to properties defined in a component defined in a different File such as file2 (of course they have to be capital letter!).

So to make it working you need 2 options:

A. to pass that property in the main file as the following one:

========== main.qml ========

Item {
File1 {
id: f1
a: f2.a // Here you bind the two properties
}

File2{
id: f2
}
}


B. Or if you really want to have "property int a: f2.a" definition inside the File1 component then you have to merge File1 and File2 in the same file:

===== File12.qml ==================
Item {
Rectangle{
id: f1
property int a: f2.a
}

Rectangle{
id: f2
property int a: 1
}

}

Hi, gnuton

I must could. I must have missed something or details.

I've created a simple project named interRef.zip
1) main.qml will get property in (content/)File1.qml
2) File1.qml will get property in File2.qml


Hope some one could help me out and tell what's this is about and where there is some detailed information.

Hi gnuton

Basically, you are right.

Using your method1, I declare

    File1{
        id: f1
    }

    File2{
        id: f2
    }

in the main file. Then file1 can get file2's property, or vice versa. Thanks very much for your answer.


But I just wondering where can I find official document about what gnuton said. en~, Nokia?
