Re: TypeError: Property '' of object QObject(0x6cfdf0) is not a function

Ok, I'm getting rather mad on this.
I just want to get a value of a bool im my C++ class:

#ifndef HPC_MANAGER_H
#define HPC_MANAGER_H

#include <QObject>
#include <QDebug>

class hpc_manager : public QObject
{
    Q_OBJECT
private:
    bool occupiedOne = false;
    bool occupiedTwo = false;
    bool occupiedThree = false;

    int occupiedSlots = 0;

public:
    explicit hpc_manager(QObject *parent = nullptr);
    bool chargerIsOccupied();
    int getOccupiedSlots();


signals:

public slots:
    void set_current_charger(int cs);


};

#endif // HPC_MANAGER_H

I think I've set it up all right here...

#include "hpc_manager.h"

hpc_manager::hpc_manager(QObject *parent) : QObject(parent)
{

}

bool hpc_manager::chargerIsOccupied()
{
    if(occupiedOne && occupiedTwo)
        return true;
    else if(occupiedOne && occupiedThree)
        return true;
    else if(occupiedTwo && occupiedThree)
        return true;
    else
        return false;
}

int hpc_manager::getOccupiedSlots()
{
    return occupiedSlots;
}

The int was just my last hope for this...

But everytime I try to get the infos within my Qml:

    function slotSelected(id)
    {
        //console.log(hpcManager.getOccupiedSlots())
        if(hpcManager.getOccupiedSlots === 2)
        {
            hpcManager.set_current_charger(id)
            t.running = false
        }
        else
            console.log("All Chargers are occupied!");
    }

I get this "qrc:/WelcomeScreen.qml:73: TypeError: Property 'getOccupiedSlots' of object hpc_manager(0x55fcc300c0d0) is not a function"
Error. I tried different stuff like !== or so... but it's either unknown or simply just says "All chargers are occupied", but this can't be, because the value is set to "0" at the beginning.

What am I missing here?

@Meistermosher To expose a function to C++ use Q_INVOKABLE or use a slot, for this change to:

Q_INVOKABLE int getOccupiedSlots();

and

if(hpcManager.getOccupiedSlots() == 2)

Please read the docs: https://doc.qt.io/qt-5/qtqml-cppintegration-exposecppattributes.html#exposing-methods-including-qt-slots

You, sir, are my rescue! :)
Thanks a lot! This saved me a lot of headache.
