[SOLVED] How to share variables between different pages ?

barmeier

Hi,

I retrieve a lot of data via a XmlHttpRequest from a server. I would like to present the data in different pages.

Could someone give me a hint ?

Thanks.

I think you can store your data in a C++ object, make it accessible from your QML page, call a method on this object in your qml, and that method in your C++ code can load the data into the target QML page .... please consider QAbstractItemModel and have look at http://doc.qt.nokia.com/4.7/qdeclarativemodels.html for examples, cheers.

Hi,
thanks for the reply, but I am unexperienced in using C++.
Do you think this is the only possibility to share data across pages ?

That would be bad.

Any other suggestions ?

Hi,

add a property to your PageStack and than you can access this property from pages by using
@
pageName.pageStack.yourPropertyName
@

I suggest not to talk with other page directly because this introduces unwanted coupling with pages. Share the data using setter and getter methods via javascript. Make sure it is a defined with .pragma library so that this JS is always shared.

Hi,

thanks for your help !

I found this in the wiki (shame on me)

http://www.developer.nokia.com/Community/Wiki/Defining_global_variable_in_QML

I think this is what srikanthsombhatla means. The hard page coupling should be no problem for me, but I want to share a JS array. It looks easier for me to try the JS-lib-thing.

Thanks a lot !
