qobject

As of Exposing Attributes of C++ Types to QML classes used with QML have to be QObject s. Any chance I can use non QObjects s (aka POCO, not derived from QObject , but registered with Qt metasystem)? If not, is there a simple generic wrapping system to make my objects QML compliant. One I can think of is to add dynamic properties to a simple QObject . Or is there a way to implicitly convert to a QML compliant type so I do not need to wrap at all? This is one hot topic actually. I believe you may register your own PODs and pass them around ito and within the QML side (just as black boxes -- w/o

I have the following problem. I am developing a model in C++ and a View in Qml, connecting them via Controllers. In my model I perform multiple calculations. I also offer users of my application the possibility, to write custom event handlers, written in qml. Now I came across a point, where I decided to use Fixed point notation and I have written a corresponding C++ class. Now I want offer the FixedPoint class - including all its operators - to developers, who decide to extend my application in Qml. So far, I offered all data as QProperties, which is required by coding guidelines. But I am

My original code passed a QStringList from the signal to the slot and then returned a QList. Everything worked fine but I needed to change both the QStringList and QList into 2 different subclassed QObjects. Since then I have been receiving errors like "synthesized method first required here" or it simply crashes without any error message. I understand that qt copies all arguments passed in a queued connection and a qobject cannot be copied. So instead of returning a qobject I thought I would create both qobjects prior to emitting the signal. Then I would pass references to each object, modify

I have a Qt application on C++ and I want to assign a slot to a QPushButton. But I want to pass some arguments because I have more than one QPushButton doing similar thing so I want one function but with a parameter in it but Qt keeps saying me that there is no slot like this. Can someone tell me why and how should I do it? Thank you in advance In the .h file I have: (it was private in the beginning but I changed it in searching of the problem) public slots: void handleButton(int row, int col); Then in the .cpp: void fieldWindow::handleButton(int row, int col){ cout << row << " " << col <<

i use Reading/writing QObjects is it true? i serialize a class with it but when deserialize it isn't the original class! what can i do? this is my base class header: class Base : public QObject { Q_OBJECT public: explicit Base(QObject *parent = 0); }; QDataStream &operator<<(QDataStream &ds, const Base &obj); QDataStream &operator>>(QDataStream &ds, Base &obj) ; and .cpp is: Base::Base(QObject *parent) : QObject(parent) { } QDataStream &operator<<(QDataStream &ds, const Base &obj) { for(int i=0; i<obj.metaObject()->propertyCount(); ++i) { if(obj.metaObject()->property(i).isStored(&obj)) { ds <

I have the following class, where I try to obtain some metadata of an enum MyEnum . However, when looping over meta.enumeratorCount() its count is always 0. Basically I was follwing this example here . In order to find the problem, I was trying the same with methods too, same problem - method count 0. Code compiles, no errors no warnings. Must be a silly mistake .... maybe you can help me class FsxSimConnectQtfier : public QObject { Q_OBJECT public: explicit FsxSimConnectQtfier(QObject *parent = 0); enum MyEnum { G1, G2 }; static const QString simConnectExceptionToString(const DWORD id); };
