Error while compiling Q_PROPERTY

Current Environment : Qt 5.8 MSVC2015 64bit, Windows 7 64 bit.

I have successfully called a C++ method from Java Script. However, I encountered an issue when trying to retrieve the return value of the C++ method in JavaScript. To address this, I attempted to utilize Q_PROPERTY for accessing the return value of the C++ method in JavaScript code.

class ExportedObject : public QObject
{   
    Q_OBJECT
    Q_PROPERTY(QString myprop MEMBER m_buffer READ GetValue WRITE GetTile)

public:
    Q_INVOKABLE void GetTile(int row, int col, int level);
    Q_INVOKABLE QString GetValue();
    QString m_buffer;

This implementation resulted in the following error :

Error: C2660: 'ExportedObject::GetTile': function does not take 1 arguments

JavaScript Code :

var image =  window.interface.GetTile( row , col ,level);

Can anyone provide insight into what may be missing in Q_PROPERTY ?

Are there any alternative approaches to retrieving C++ return values in JavaScript?

Answer №1

After some investigation, I stumbled upon a straightforward fix for this issue. There is no requirement for Q_PROPERTY in this case:

window.interface.GetTile( row , col ,level, function(returnValue) {
    alert(returnValue);
});
