how two connect two qml file using simple buttom

preeth

can anybody give a simple program to connect 2 qml files. when a button is clicked in one qml, the other qml file should open, please help,

I think you misunderstand the concept behind QML and parent-child hierarchy. But, to answer your query: use Loader element.

@sierdzio
i am very new to qml,
can you please explain with a code snippet

Beberd

I have do this with an Loader Item.
example:
@ Item {
anchors.fill: parent
width: parent.width
height: parent.height

    Loader {
        id: pageLoader
         }

}@

When the button is clicked, you emit a signal changePage().

And you can write a slot like this:
@ function getHomePage()
{
pageLoader.source = "home.qml";
}
@
Then you connect the slot and the signal in the main.

Please wrap your code in '@' tags. And thanks for that snippet, I was too busy to answer myself.

I am suffering from the same problem (not understanding the concept behind QML and parent-child hierarchy).
Have been searching for hours. Is there a link explaining this topic?
Need to keep all QML pages in memory (for they need to stay connected to C++), so loader will not do the job.
Thanks.

After the Loader finishes loading the file, it's content (available under item property) works the same as content loaded on application startup, and can be connected with C++ just the same.

Search Qt documentation, it's very helpful in most cases. And for QML - create some example projects. It takes a day or two to get used to the idea (declarative world is different from imperative one, after all), then it's all nice and rosy ;)

wspilot, you should create another topic and state your exact issue or goal. Other than that, you ought to have a look at some ready C++&QtQuick examples out there and practice, like sierdzio has already said.

"QDeclarative code samples":http://doc.qt.digia.com/4.7/qdeclarativeexamples.html

"QtQuick 2 code samples":http://qt-project.org/doc/qt-5.0/qtquick/qtquick2-qtquick-codesamples.html

Thanks.
Have done that for weeks. Have several Sailfish and plain QML sandboxes set up (but basically for C++/openGL <> QML testing).
I now need to navigate between the QML pages (and keep them in memory). In the normal GUI world very simple: hide, show, popup etc., but I cannot find sth. simular in QML.

@
visible = false;

Every Item has this property ;)

wspilot

Aha.
So, I'll create one main.qml with the specific UI pages based on components and use visible as switch.
Thanks.
