    Default Log In Page

    Hello, I'd like to ask question regarding connecting the QML to cpp, my goal is to send parameter from QML in forms of username and password to cpp, the cpp itself is connected with the GSoap. If the results return true, then the user can move to another page and if wrong username and password were send, nothing will happen; but at the mean time, I'd just show some text at the console screen. This is my code, please give me a clue of what i was lack at.
    Qt Code:
    1. //LogInPage
    2. import QtQuick 1.0
    3. import "comp"
    4.  
    5. Rectangle
    6. {
    7. id: mainWindow
    8. width: 360; height: 360
    9. signal dataRequired(string msg,string msg);
    10. function success() {console.log("connection done")}
    11. function fail() {console.log("fail")
    12. Image
    13. {
    14. id: backgroundAbout
    15. source: "comp/pic/background-about.jpg"

    Not to be rude but do you expect us to analyze and debug your code for you? You didn't even say how this code misbehaves with what you expect from it.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Sorry, I didn't mean to do so. I should have ask a more specific question. But by the way, it had been solved now, this is the link, just in case if anyone would want it: http://doc.qt.nokia.com/4.7-snapshot/qtbinding.html
