Extending QML - Adding Types Example

[akrynski]

Hi everyone!
I have just writen my own class in c++ and added it as a type to use with QML - just like in example in topic.
All seems to be ok except nothing is working
I get an error:

QDeclarativeComponent: Component is not ready
(qrc:mySysInfo.qml: File not found)

Path to mySysInfo.qml is in resource editor set to:

 <!DOCTYPE RCC><RCC version="1.0">
 <qresource>
     <file>qml/QtQuick2/mySysInfo.qml</file>
 </qresource>
 </RCC>

Remark: mySysInfo.qml is not a main project file but I want to use it as a component in main,qml.
What am I doing wrong?

The second question is I included into mySysInfo.h headers <QSystemInfo> and <QSystemDeviceInfo>, CONFIG += mobility
MOBILITY += systeminfo in application .pro file but when I try to write something like this

 QSystemDeviceInfo *si;
    si =  new QSystemDeviceInfo(this);

I get build error

E:\SYMBIAN\moje\QtQuick2-build-simulator\..\QtQuick2\mySysInfo.cpp:8: błąd:'QSystemDeviceInfo' was not declared in this scope

Why?

Hi,

1. The component's filename must always start with a capital letter.
2. Have you forgotten to add #include <QSystemDeviceInfo>?

ad.1 - I change it tomorrow and try again
ad.2 - no. it is included

Ok, I have changed all file names to beginn with capitals, my library name too but nothing is changed. I have the same errors.
I think the purpose of errors is that my component is being made dynamicly and the main interface (main.qml) is done by qmlaplicationviewer. But how to solve this conflict if it really is a conflict.
Ok, I solved it - it is not allowed to mix two different types of view: standard (by viewer) and declarative view.
My component works great except that it shows undefined values because I slill can not use QSystemDeviceInfo etc.
Here is my .pro file:

folder_01.source = qml/QtQuick2
folder_01.target = qml
DEPLOYMENTFOLDERS = folder_01

Qt += declarative

# Additional import path used to resolve QML modules in Creator's code model
QML_IMPORT_PATH =

symbian:TARGET.UID3 = 0xE26A57B0

SOURCES += main.cpp \
    mySysInfo.cpp

CONFIG += mobility
MOBILITY += systeminfo


include(qmlapplicationviewer/qmlapplicationviewer.pri)
qtcAddDeployment()

HEADERS += \
    mySysInfo.h

RESOURCES += \
    MySysInfo.qrc

Best regards, Andrzej.

I hate replying to myself but someone can find it helpfull
So I found my foult - wrong location of QTM_USE_NAMESPACE clausule.
But I still get undefined values from my component, perhaps from QSystemDeviceInfo class.
Let you see my code:

#include "mySysInfo.h"
#include <QSystemInfo>
#include <QSystemDeviceInfo>
#include <QDebug>
mySystemInfo::mySystemInfo(QObject *parent)
: QObject(parent)
{

    QSystemDeviceInfo* si;
    si =  new QSystemDeviceInfo(this);
    this->setManufacturer(QString(si->manufacturer()));
    qWarning() << "Manufacturer name is" << si->manufacturer();
    this->setProductName(si->productName());
    this->setModel(si->model());

    delete si;
...
...
QString mySystemInfo::manufacturer() const
{
    return m_manufacturer;
}
....
...

and from main.qml:

...
...
 Text {
        id: info

        text: "manufacturer = " + MySysInfo.manufacturer
...
...

By the way: I can't see any reply from qWarning so I can not check what happens.

CAN ANYBODY HELP ME? Now I really don't know what to do
