How to connect a Button to FileDialog function in ubuntu sdk?

Question

I've just started to deploy my first application for Ubuntu using QtCreator 3.1.1 based on Qt5.2.1 on Ubuntu 14.10.. I need to open some video files, so I'm going to put a Button to choose file obviously. Also I know I can use this function to open files:

FileDialog {
    id: fileDialog
    title: "Please choose a file"
    onAccepted: {
        console.log("You chose: " + fileDialog.fileUrls)
        Qt.quit()
    }
    onRejected: {
        console.log("Canceled")
        Qt.quit()
    }
    Component.onCompleted: visible = true
}

Here's my question: How can I connect them to each other? I want the FielDialog to be opened when I click on the button. And is that the only way to do this? I mean couldn't I do the same process in C++ code?

Of course you can do in C++. There's a Qt class called QFileDialog: http://qt-project.org/doc/qt-5/QFileDialog.html You can simply connect a button clicked signal to a slot that creates a QFileDialog, you can use some of the static functions like in the example:

fileName = QFileDialog::getOpenFileName(this,
    tr("Open Image"), "/home/jana", tr("Image Files (*.png *.jpg *.bmp)"));

and here how to use the QPushButton: http://qt-project.org/wiki/How_to_Use_QPushButton
